What are the coils in a freezer?
frozen water
My freezer works but the refrigrator doesn't?
Your refrigerator may have coils or connections which are independent of the freezer.
What happens to the thermal energy if you put a cup of water into the freezer?
Thermal energy in the water is transferred to the air in the freezer, mainly by convection. From there, it is absorbed by the evaporator coils which line the interior of the freezer; the refrigerant fluid in the coils circulates to the outside, where it is compressed and the heat is dissipated into the room as it passes through the condenser coils on the outside of the freezer.
How do you recoil a chest type freezer?
A chest type freezer can be recoiled by draining the coolant and cutting the coil lines. New coils are then soldered onto the inlet and outlet and the system is recharged.
How does a frost-free freezer work?
If you have an old refrigerator or one of the small dorm refrigerators, you know all about the frost that forms around the coils that cool the freezer. If you let it build up long enough, the frost can get 6 inches thick and eventually there is no room to put anything in the freezer. This frost forms when water vapor hits the cold coils. The water vapor condenses -- turns to liquid water. Think of the water beading up on a glass of iced tea on a summer day -- that is an example of water vapor in the air condensing. The same thing happens on the ice-cold freezer coils, except that when the water condenses onto the coils it immediately freezes. A frost-free freezer has three basic parts: * A timer * A heating coil * A temperature sensor Every six hours or so, the timer turns on the heating coil. The heating coil is wrapped among the freezer coils. The heater melts the ice off the coils. When all of the ice is gone, the temperature sensor senses the temperature rising above 32 degrees F (0 degrees C) and turns off the heater. Heating the coils every six hours takes energy, and it also cycles the food in the freezer through temperature changes. Most large chest freezers therefore require manual defrosting instead -- the food lasts longer and the freezer uses less power.
Can a microwave be on top of a fridge freezer?
Yes. The short waves that bounce around inside the oven should be well shielded from penetrating the freezer ice. Heat from the freezer coils rises, but that should not harm the microwave. Neither device should have any negative impact on the other in that configuration.
Can I keep my freezer in the garage in the winter?
Your freezer operates on the basic principles of the refrigeration cycle. Your freezer does not make cold, it removes heat from the cabinet space. That heat is then discharged to the outside of the unit via a set of coils (either on the back or bottom of the unit). This cycle should keep the operating components of your freezer operating well throughout the winter months.
Can you put a deep freezer in storage?
You can store a deep freezer, however there are a few things to keep in mind when doing so. To prepare the freezer for storage, first empty the contents. Clean the freezer with a mild soap/detergent and leave the lid open for it to dry out completely. When moving the freezer (and during storage as well), be sure to avoid placing it on it's side--always keep it upright! If on it's side, the coils and liquid lines can leak and permanently damage the freezer system.
Why are freezer on top of fridge?
One possible reason is because of the size of the freezer compared to the size of the refrigerator portion. If the refrigerator portion were placed over the freezer, then you would have to kneel down to use the freezer. Another part of it could pertain to convection. Cold air tends to circulate down. So with the right amount of gap between the freezer portion and the rest, just enough cold air can flow down to cool the refrigerator. So the evaporator coils are only in the freezer and yet can cool the entire unit. If the evaporator coils were on the bottom, then only the lower portion of the refrigerator would be cool since heat rises, and some of the cavity space would be wasted. So for simplicity and efficiency, the coils are placed on top and that this area is made the freezer. So they cool only the freezer and have a small opening to let the cold air come down (or warm air to come up to be more accurate) to reach the 34-38 degrees Fahrenheit needed for the refrigerator. Sometimes there is an adjustable damper there. The thermostat is just for the refrigerator in most cases, since if the refrigerator is within proper range, the freezer would be too, all because of the design. On those with a control for the freezer, that control generally moves a little damper (door). So the colder you set the freezer, the harder you are making the refrigerator portion to cool. Since the actual thermostat is located in the refrigerator section, the longer the compressor must run to make that compartment the proper temperature when you close the damper (by setting the freezer control colder).
What are some common mechanical problems with freezer appliances?
Common mechanical problems that may occur with freezer appliances include the fuse not working, faulty wiring occurring over prolonged periods of use, a faulty thermostat cooling to an incorrect temperature or stopping completely and even coils within the freezer failing to freeze within an efficient amount of time.
What the problem when your refrigerator stop working because you notice 6 little fork holes are in the top freezer part?
If you have an older refrigerator that needs to be manually defrosted and you have scraped the ice from the coils compartment with a fork, you probably pierced the coils and now have no coolant in the refrigerant system. Time for a new refrigerator.
Can you get sick from frost burned ice-cream?
sure it is!! And, it tastes so good! the frost is from humidity in the air (when you open the door), or foods placed in the freezer (especially hot foods) which freezes, the humidity that is, on the coils of the freezer. the cold gas in the coils cause it to freeze. yum yum yum.. freezer frost!
