When nosotros moved to our electrical current house, our oldest boy was 3 in addition to boy #2 was precisely almost to live born. We moved because nosotros needed a larger house, which included infinite for a breast freezer. As shortly equally nosotros got the keys, nosotros ordered a pocket-size breast freezer in addition to pose it inward the garage. It was similar a huge luxury.
But estimate what? We should direct hold ordered a bigger on. Keep that inward hear – if you’re getting a standalone freezer, acquire a large one. You won’t regret it.
A freezer is an appliance that stores in addition to preserves nutrient at rattling depression temperatures. Sometimes, it is a split compartment that is attached to a fridge in addition to at times, it is a split appliance altogether.
The freezer is i of the most commonly used appliances, both domestically in addition to commercially. Influenza A virus subtype H5N1 freezer is essential for keeping foods preserved for a long time. It keeps the nutrient at extremely depression temperatures which ensures that the nutrient is protected from whatever microbial contamination in addition to damage. The machinery past times which a freezer plant is quite simple. Influenza A virus subtype H5N1 fiddling noesis almost its components in addition to working tin assist you lot educate the problems that may arise from fourth dimension to time.

Refrigerant
The refrigerant is a chemical compound which is commonly constitute inward the gaseous state. It absorbs oestrus produced during the refrigeration physical care for readily in addition to provides cooling necessary for freezing. Without refrigerant, at that spot would live no freezing. After the refrigerant absorbs heat, it converts into a high-pressure liquid from a low-pressure gas.
The most mutual refrigerants used are:
- CFCs (Chlorofluorocarbons), including R12: They contributed greatly to the greenhouse effect. New stocks of CFCs direct hold non been produced since 1994.
- HCFCs (Hydrochlorofluorocarbons), including R22: HCFCs are less damaging to the ozone equally compared to CFCs. HCFCs volition live completely phased out past times 2020 equally a termination of the Clean Air Act.
- Hydrofluorocarbons (HFCs), including R410A in addition to R134: They do non comprise whatever chlorine. Hence, they are safer for the environment. HFCs are instantly used inward identify of R22.
Components of a Freezer
A freezer is composed of unlike components that cast a freezing system. This scheme is responsible for the freezing effect. The major parts of a freezer are equally following:
- Compressor
The compressor is a reciprocating pump that is hermetically sealed. Influenza A virus subtype H5N1 compressor is the catch of the entire refrigeration system. It is responsible for pumping the refrigerant gas to all the parts of the freezer to hold the refrigeration bike running repeatedly. The sizes of compressor vary according to the load-bearing capacity of the freezer. The sizes make from 1/12 to 1 horsepower.
A compressor is enclosed inward a steel casing. Inside the steel casing, at that spot is an electrical motor, piston, cylinder, crankshaft, intake, exhaust valves, connecting rod, in addition to a ceramic terminal block. Influenza A virus subtype H5N1 pocket-size quantity of Capilla oil is also nowadays within.
- Condenser
Condensers are the oestrus exchangers of freezers. The condenser is made of coiled serpentine copper amongst aluminum fins. It is located at the raise terminate of a freezer. The purpose of a condenser inward a freezer is to withdraw all the oestrus that is supplied to the refrigerant inward the evaporator in addition to the oestrus produced inward the compressor during compression. It also condenses the vapors of the refrigerant into a liquid.
Condensing units are of diverse types.
- Evaporating Type: In an evaporative type of condenser, the gyre assembly is housed within a steel casing. Air is forced through the coils in addition to discharged on top of the unit.
- Air-Cooled Type: In an air-cooled type of condenser, the coils are housed within a steel casing that is opened upward at the top in addition to bottom. The cooling of coils is done past times natural air.
- Water-Cooled Type: In this type of condenser, the H2O enters into the cylinder inward which coils are enclosed. The H2O circulates within the coils in addition to discharged through the outlet pipe.
A farther classification of condensers is equally below:
- Finned-Static Type: In this type of condenser, the coils are held together amongst the assist of rattling sparse fins which supply to a greater extent than expanse for the transmission of oestrus into the atmosphere.
- Plate-Static Type: In plate-static type condensers, the oils are sandwiched within a rectangular steel box.
- Wire-Static Type: For this type of condenser, the coils are held inward identify past times direct steel wires that cast a rectangular shape.
- Convection Type: the coils are enclosed inward a steel box inward this type of condenser. The air is forced through the coils amongst the assist of an attached fan.
- Finned-Forced Convection Type: It is a convection type of condenser amongst a fan that cools coils.
- Filter/Dryer
This cistron of a freezer is responsible to filter whatever Fe particles, moisture, in addition to dirt from the refrigerant in addition to hold them from entering the refrigeration system. If left unfiltered, the period of time of refrigerant into the expansion valve volition live restricted. Some filters/dryers fried comprise a wet absorbent fabric similar silica gel that absorbs whatever wet that may live nowadays inward the refrigerant. The filter/dryer is responsible for protecting the compressor past times filtering or restricting whatever impurities or wet content that may direct hold contaminated the refrigerant.
Filters are of 2 types:
- Flare Tube Connection: They may acquire lose over fourth dimension due to the constant racket inward the refrigeration scheme in addition to crusade a refrigerant leakage problem.
- Brazing Connection: Refrigerant leakage inward this type of filter is less probable to occur equally the joints are brazed.
- Expansion Valve
Expansion valve or capillary subway scheme made of copper is some other mutual cistron of a refrigeration system. It controls the period of time of refrigerant through the system. High-pressure liquid refrigerant enters the expansion valve in addition to leaves equally depression pressure, low-temperature liquid refrigerant.
It is necessary that the refrigerant is converted into low-pressure refrigerant earlier entering the evaporator. When it absorbs heat, it is converted into gas. Influenza A virus subtype H5N1 compressor allows only gas refrigerant to go inward since gases tin live compressed in addition to liquids cannot live compressed.
The outer diameter of an expansion valve is 2.5mm in addition to the length is commonly betwixt 8 feet to 12 feet.
There are 5 unlike types of expansion valves:
- Capillary Tube Type: This type is made upward of pocket-size copper tubing. Having a hole amongst diameter from 1mm to 3mm. it serves equally a consistent limiting valve for the period of time of refrigerant from the condenser to the evaporator.
- Automatic Expansion Type: This type of expansion valve controls the period of time of refrigerant past times a uncomplicated machinery of opening in addition to closing of a command valve for depression pressure. The refrigerant is sprayed into the evaporator.
- Thermostatic Expansion Type: This type of expansion valve controls the refrigerant period of time past times sending signals to a sensing bulb which is attached to an outlet of the evaporator. This sensing bulb sends instructions to the valve for opening in addition to closing.
- Low-Side Float Expansion Type: The valve is controlled past times a finned cooling coil. Influenza A virus subtype H5N1 constant flat of refrigerant is maintained inward the evaporator.
- High-Side Float Expansion Type: It is the same equally the low-side float expansion type. The only divergence is that it keeps the evaporated completely flooded amongst liquid refrigerant.
- Evaporator
The evaporator is a serpentine aluminum subway scheme cistron amongst aluminum fins. It is responsible for absorbing oestrus inward the freezing compartments in addition to transferring it all to the condenser. After the low-pressure liquid refrigerant absorbs this heat, it becomes gas. This refrigerant vapor makes its journeying to the compressor, through the accumulator. - Accumulator
An accumulator accumulates refrigerant. It behaves equally a refrigerant tank ensuring that the evaporator does non run out of it. If at that spot is no accumulator, symptoms of refrigerant starvation volition acquire visible. - Fan Motor
The primary purpose of a freezer fan motor is to hold the compressor cool. It is situated inward the compressor room, precisely beside the compressor. It is composed of a steel bracket in addition to a stand upward in addition to is constitute bolted into a cross member. The fan runs amongst the compressor. If the aluminum blade of a fan is bent during maintenance, it tin vibrate quite furiously which is detrimental to the shaft bearings. This tin crusade an early on breakdown of the freezer.
If whatever cistron of a freezer is non working properly, they would non supply the cooling in addition to would crusade defrosting.
How Do Freezers Work?
The machinery past times which a freezer plant revolves about drawing oestrus out from the freezing compartment. At the kickoff of the process, the gaseous refrigerant goes into the compressor where the refrigerant is compressed. The temperature of the gas at this signal is rattling high. As the hot gaseous refrigerant moves through diverse coils inward the freezing system, it loses its oestrus in addition to starts to cool off.
As the gaseous refrigerant is cooled to a rattling depression temperature, it is liquefied. It is so forced into the expansion valve which converts the liquid refrigerant into a mutual depression temperature mist past times forcing it through its extremely pocket-size opening.
The mutual depression temperature mist moves through the scheme through to a greater extent than in addition to to a greater extent than coils. It starts evaporating in addition to comes dorsum inward a gaseous state equally it absorbs oestrus along the way. At this point, the temperature of the mist is -27 degrees. It takes the oestrus of the freezing compartment amongst it, thus turning dorsum into the gas form.
When the refrigerant becomes gas again, it gets moved to the compressor i time to a greater extent than where it is compressed in addition to the physical care for is repeated. The physical care for continues until the refrigerant has taken away all the oestrus from the freezing compartment, leaving behind none. This is what causes the nutrient inward a freezer to freeze.
Types of Freezers
There are 5 types of freezers available. You tin select the type that suits your requirements.
1. Chest Freezers
Chest freezers are also called reach-in freezers. They are the most mutual types of freezers that are used commercially. They are economical in addition to spacious. The interior in addition to exterior are shaped similar a large box that gives it amazing storage capacity. Chest freezers direct hold hinged lids that opened upward upwards in addition to are slow to use.
A drawback of breast freezers is that their large size requires a lot of space. Also, these freezers do non direct hold a fan which results inward an inconsistent temperature. The bottom expanse of the freezer is cooler equally mutual depression temperature air is heavier. Therefore, meats are commonly stored inward lower parts. An additional characteristic of baskets inward the freezer helps amongst ameliorate organization in addition to slow access to stored items.
The capacity of breast freezers ranges from 2.1 cubic feet to xl cubic feet. Because of its exceptionally large storage capacity, they are used commercially inward hotels, restaurants, in addition to other large-scale businesses for storing mass foods.
2. Upright Freezers

- Standalone
- Stacked fridge freezer – amongst freezer higher upward or below the refrigerator
- American-style side-by-side freezer
a. Standalone upright freezer
An upright freezer costs twice equally much equally the breast freezer. However, an upright freezer is worth the money. Unlike breast freezers, the upright freezers direct hold to a greater extent than elevation in addition to they comprehend less flooring space. This makes them suitable for domestic use. Because of their vertical design, they allow slow access to stored items. Most of the items are at an optic level. The compartments inward an upright freeze are stacked which is some other argue why the stored items are easier to access in addition to retrieve.
b. Refrigerator amongst freezer below
c. Refrigerator amongst freezer on top
d. Side-by-side refrigerator/freezer
3. Drawer Freezers

Frequently asked Questions
Below are answers to mutual questions almost freezers.
How do freezers work?
Modern freezers hold foods frozen past times combining the cabinet pattern amongst high-quality insulation materials in addition to a physical care for that uses electricity to run a freezing scheme that pulls oestrus from the freezer interior in addition to replaces it amongst cool air. Refrigerant, whatever gas that tin absorb heat, cools air temperature via thermodynamic cycles that involve compression in addition to evaporation. Influenza A virus subtype H5N1 freezer compressor condenses the gas until it becomes an incredibly hot liquid. The liquid is forced through coils on the exterior of the unit of measurement in addition to cools when exposed to ambient air temperature. The cooler liquid passes through an evaporator that allows it to speedily mist in addition to expands dorsum into a gaseous state, which causes an automatic absorption of heat.
What is freezer burn?
Freezer displace appears equally H2O ice crystals on i or to a greater extent than spots on nutrient coupled amongst a dried out, discolored and/or tough surface. Influenza A virus subtype H5N1 freezer displace spot typically looks brown, grayness or white. The surface texture tin experience grainy or fossil oil to the touch. With certainly foods, the surface tin acquire powdery or collapse when touched amongst a finger or object. Any nutrient that has experienced freezer displace commonly has an off odor. People tin yet eat it, but it commonly tastes off in addition to unpleasant.
How do you lot forestall freezer burn?
People should ever withdraw equally much air equally possible from nutrient packages via a vacuum seal or manual method. For example, a someone powerfulness insert a straw into a freezer bag, seal the purse except for at the straw, suck out the air manually, delineate out the straw in addition to press the seal. Double-wrapping foods amongst aluminum foil inward improver to freezer newspaper or plastic wind tin also help. People should also repackage previously frozen foods that distributors failed to identify inward air-tight bags or boxes. Freezing certainly foods inward containers filled amongst H2O tin also protect them from freezer burn.
What causes freezer burn?
Dehydration in addition to oxygen exposure are the primary causes of freezer burn. When a someone doesn’t seal nutrient plenty to withdraw air from a freezer purse or container or plastic wrap, H2O molecules dissipate in addition to release into the opened upward infinite about the food. The H2O turns into H2O ice that settles on the surface. Oxygen molecules seep into the spaces that previously held H2O in addition to so degrade the nutrient in addition to adversely bear upon its color, scent in addition to taste.
How mutual depression temperature should a freezer be?
A freezer must direct hold a temperature of 0 degrees Fahrenheit or lower, depending on the specifications provided past times the manufacturer of a specific model, to hold foods frozen to the signal of preventing decay in addition to spoilage. Influenza A virus subtype H5N1 someone should ever banking concern check their freezer at to the lowest degree i time a calendar week amongst a thermometer designed specifically to brand certainly that the unit of measurement plant properly.
Can freezers live likewise cold?
A freezer’s temperature should never give-up the ghost below the manufacturer’s recommended setting for a specific model. If a freezer thermometer shows a colder temperature in addition to frost buildup, someone powerfulness direct hold laid the temperature likewise depression or failed to manually defrost the freezer, when necessary, at to the lowest degree i time a year. In both manual in addition to automatic defrost freezers, defective in addition to broken parts tin crusade this problem. For example, a defective or broken defrost heater that fails to melt frost from the evaporator coils or a non-working evaporator fan tin crusade the temperature to drib likewise low.
Who, where in addition to when was freezer invented?
Before the advent of modern refrigeration in addition to freezing of stored foods, people kept their nutrient rubber from immediate deterioration using a diversity of methods, including caves, origin cellars in addition to in-ground holes in addition to boxes filled amongst H2O ice or snowfall in addition to insulating materials similar straw.
In 1802, American Thomas Moore so patented a pattern for a habitation insulated, cabinet-style icebox that featured an enclosed zone for nutrient in addition to a split zone for H2O ice that would hold the entire unit of measurement cool for or so 5 to vii days. Modern refrigerators in addition to freezers utilization a similar cabinet design, but freeze via an artificial refrigeration physical care for known equally evaporative cooling that maintains temperatures slightly higher upward or below the freezing signal of water, respectively.
Several inventors direct hold received credit for artificial refrigeration:
In 1748, a Scotsman named William Cullen provided the populace amongst a demonstration of the evaporative cooling process.
In 1805, American Oliver Evans designed a vapor compression refrigeration system. In 1834, his co-worker, Jacob Perkins, built a epitome amongst liquid ammonia.
In 1844, American John Gorrie introduced a pattern based on Evans’ idea.
By 1876, liquifying gas for the evaporation physical care for was patented past times High German Carl von Linden.
All of these discoveries in addition to technical designs eventually resulted inward American Nathaniel B. Wales inventing in addition to patenting past times 1914 an electrical refrigeration unit of measurement for habitation utilization called the Kelvinator. In the 1940s, consumer demand for improved longer nutrient storage in addition to greater cabinet storage capacity prompted manufacturers to create dual fridge in addition to freezer units in addition to standalone freezers known equally deep freezes.
Are freezer bags recyclable?
Many of the freezer bags on the market, including sealable plastic nutrient storage in addition to freezer bags in addition to prepackaged bags, are recyclable. People should ever banking concern check the resin identification code located within of the “three arrows triangle” symbol on their bags. Grocery in addition to retail stores in addition to municipal recyclers collect clean, recyclable bags. People should also withdraw plastic zippers from zipper-style bags earlier recycling. Thankfully, these zippers are groovy for utilization inward a diversity of upcycle crafts. As for non-recyclable freezer bags: They’re designed for durability, which makes them perfect for other types of habitation in addition to business office storage.
Are freezer bags waterproof?
Many consumers believe that freezer bags are waterproof, but most companies only marketplace these bags equally “leak-resistant” because the designs tin neglect when their bags are submerged nether H2O for a long time. It’s of import to greenback that leakage tin yet go on amongst leak-resistant bags because of manufacturing defects in addition to accidental damage.
Can freezer nutrient give-up the ghost bad?
In a perfect freezer scenario, frozen nutrient is rubber to eat forever, equally long equally it’s ever kept frozen at the correct temperature. Freezer displace does occur amongst long-term storage. Frozen nutrient also experiences harmful bacteria growth when temperatures fluctuate or rising higher upward normal. Temperature problems go on when a freezer isn’t total plenty or someone leaves the door opened upward likewise long in addition to nutrient defrosts. Other defrost events tin occur if a freezer door seal or whatever other constituent of the scheme fails. During a powerfulness outage, a full, unopened freezer tin maintain the correct temperature for upward to 48 hours.
Can a freezer live likewise full?
When a freezer is full, the frozen nutrient reduces the piece of work that the freezer must do to hold the interior cool. During a powerfulness outage, it also acts similar H2O ice inward a cooler. On the other hand, an overly total freezer amongst blocked vents restricts airflow in addition to causes nutrient to defrost inward spots. The condenser also overworks. An overworked condenser increases an electrical nib in addition to eventually breaks.
What is freezer paper?
Freezer newspaper is only standard, thick butcher vogue newspaper altered slightly amongst a plastic, resin or wax coating on i side to forestall leakage when used to wind meats in addition to unlike foods that comprise juices or other fluids. Freezer newspaper plant good for storage for upward to a year. It’s perfect for exterior double-wrapping of plastic-wrapped meats. It’s also practiced for labeling purposes since the non-coated exterior surface is patently paper.
Where to purchase a freezer online?
Anyone tin discovery a freezer or refrigerator/freezer combo that fits their needs past times running a uncomplicated online search using the keyword phrase “buy a freezer.” Since transportation large appliances costs a lot of money, many shoppers purchase through a local appliance, slice of furniture or subdivision store’s website to have gratuitous or low-cost local delivery. Many e-commerce sites that offering subscription services include the cost of transportation inward their monthly membership fees. It’s critical that a someone who finds a freezer model that they similar compare reviews on multiple websites to larn almost whatever model or merchant problems experienced past times existing owners.
Why does H2O ice create upward inward a freezer?
Frost happens when a freezer’s temperature fluctuates oft or the freezer fails to maintain the appropriate overall temperature inward spots. These temperature problems occur when a someone opens the freezer door likewise much or the door hinges or seal don’t business office per pattern specifications because of loose installation, detachment or misfortunate alignment. In these scenarios, exterior warmer air enters the freezer in addition to increases the temperature plenty to cast condensation on frozen nutrient packages in addition to freezer walls. The temperature eventually balances out plenty to refreeze everything, but a bike of defrost in addition to freezing happens that causes H2O ice layers to create up. This work tin also occur when certainly parts overheat, the drain clogs or the possessor installs the freezer likewise unopen to a wall or fails to create clean the coils in addition to external vents.
Difference betwixt Freezing in addition to Deep Freezing
Freezing in addition to deep freezing are 2 alone unlike things. Although they both involve the freezing of food, at that spot is a major divergence betwixt the two.
Freezing
Freezing involves a tedious decrease inward temperature. It may accept upward to 24 hours to freeze a nutrient particular completely. The H2O that is contained inward the nutrient is converted into large H2O ice crystals. Many individuals utilization this technique to hold their nutrient frozen.
A major disadvantage of freezing is that the nutrient items beingness frozen may acquire dry out in addition to damaged. Since the crystals are large, they may terminate upward perforating the jail cellular telephone walls of the nutrient items. Aroma in addition to parts of H2O may escape the food.
Deep Freezing
Deep freezing involves a rapid decrease inward temperature. It is an industrial technique that freezes the foods at extremely depression temperatures. It takes only a few minutes to i hr to completely freeze the nutrient items. In this technique, nutrient is exposed to extremely depression temperatures, commonly -30 to -50oC. It causes the substance temperature of the production to attain equally depression equally -18oC. As a result, the H2O that is nowadays inward the nutrient is finely crystallized. The proliferation of microorganism in addition to killing of cells is limited. The products that are frozen past times this technique retain their freshness in addition to season because the cells acquire dormant.
Unusual Uses of Freezers
Apart from storing foods in addition to beverages, freezers tin live used for diverse purposes which you lot powerfulness direct hold non thought almost before. Below are some odd yet interesting uses of a freezer:
- If you lot direct hold bought a shoe that is a fleck snug for you, a freezer tin assist you lot acquire inward your size. Fill a sealable plastic purse amongst H2O in addition to identify it your shoe. Put the shoe amongst the plastic purse inward the freezer overnight. Your shoe volition live stretched plenty to brand them tally you lot nicely. If you lot desire to stretch it more, repeat the same procedure.
- If you lot direct hold bubblegum stuck to the sole of your shoe, you lot tin acquire it off amongst the assist of your freezer. Just identify a slice of newspaper on the bubble mucilage in addition to freeze the shoe for 1-2 hours. The bubblegum volition come upward off easily.
- You tin hold the lipsticks inward a freezer to hold them fresh. Cold temperatures are ideal for keeping lipsticks in addition to a freezer is the absolute best pick for this.
- Before sharpening your eyeliner, identify it inward a freezer for xv to twenty minutes. Sharpening the eyeliner afterwards doing this volition give you lot a perfectly pointed tip.
- Keeping your candles inward a freezer tin increment their life. Their burning fourth dimension tin live increased upward to 2 times.
Freezers are a must-have inward today’s era. Every identify has a freezer. Imagining life without i is precisely non possible now. Understanding how they work, the types of freezers that are available in addition to the proper usage tin assist you lot hold your freezers maintained for a rattling long time.
