Currently, there are various types of freezers in design, style, size and price. In the following article Mobile World will outline the types of freezers currently on the market, the advantages and disadvantages of each and the type that suits your needs.
1. What is a freezer?
– Define
Freezer is household appliances used for cold storage including an insulation chamber and a heat pump system that transports temperatures from inside the chamber.
With temperature below – 18 degrees Celsius that freezer provides, bacteria cannot grow from which freezer can preserve and ensure food quality in the long run.
– Structure of the freezer
Here is the basic structure of a freezer:
+ Cabinet door
Freezers located are equipped with open doors like suitcases. Freezers are designed to open the front door like a refrigerator. Insulation gaskets is surrounded by the cabinet.
+ Insulation system
The insulation system helps the surrounding high temperature do not penetrate into the cold chamber. In other words, this system prevents the exchange of air inside and outside the freezer.
+ Outdoor unit – indoor unit
Outdoor play the role of radiating heat to the environment outside the cabinet. This is where the high pressure of the compression pump causes the refrigerated gas to liquefy and radiate heat into the environment.
The temperature of liquid cold gas will be almost equivalent to the ambient temperature after passing through the outdoor unit.
Cooler is to act as a heat collector outside the cabinet. This is where the cold liquefied gas from the outdoor unit goes through the throttle valve system to evaporate. This means that the liquid gas will no longer be compressed and evaporates quickly.
During evaporation, the gas draws heat and then cools the space inside the freezer.
+ Compressor
Compressors, also known as engines, cyclones help compress cold gas (refrigerant) at high pressure to cool liquefied gas.
The liquefied cold gas heats up a lot due to the heat generated through this compression process. The liquefied gas then passes through the condenser, where the temperature from the cold gas radiates to the outside environment.
Compressor rotor or compressor 1 or 2 cylinder piston is the type of compressor used a lot.
Civil freezers are commonly used 1-cylinder piton machines.
+ Gas
Gas R134a, and R600a are the kind gas Commonly used in most chillers. Besides, there are other types of gas R22 and gas R410a.
– Operation principle
The freezer operates on the principle of easy liquefied refrigerant (refrigerant). Gas in the form of gas will turn into a liquid state and generate heat after being compressed by the compressor under high pressure.
Through the outdoor unit, radiant heat will be dissipated into the surrounding environment. When the pressure drops, the liquid gas will turn into a gas state and absorb the surrounding heat in the indoor unit.
