A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which

                                                   had been a common household appliance for almost a century and a half. For this reason, a refrigerator is sometimes referred to as an icebox

                                                   in American usage. The refrigerant (working fluid) absorbs the heat of the outside (cooled material) in the evaporator and evaporates into gas

                                                   to enter the compressor. The gas is compressed by the compressor and the temperature rises. The gas discharged from the compressor

                                                   enters the condenser and is cooled to a liquid. When the refrigerant liquid exiting the condenser flows through the throttle body, the pressure

                                                   and temperature are reduced to become a two-phase mixture composed of gas and liquid, and then enter the evaporator to absorb the heat

                                                   of the objects around the evaporator, so that the temperature of the evaporator is reduced. To achieve the purpose of refrigeration.

                                                   Freezer units are used in households and in industry and commerce. Commercial refrigerator and freezer units were in use for almost 40 years

                                                   prior to the common home models. The freezer-on-top-and-refrigerator-on-bottom style has been the basic style since the 1940s, until modern

                                                   refrigerators broke the trend. A vapor compression cycle is used in most household refrigerators, refrigerator–freezers and freezers. Newer

                                                   refrigerators may include automatic defrosting, chilled water, and ice from a dispenser in the door.

                                                   The compressor serves as a key component in the refrigeration system.

                                              Refrigeration system: A combination of components that transfer heat from one place to another. Understand how the system operates

                                              Coolant: Responsible for heat exchange between internal and external environments.

                                              Condenser: Transfer the heat from the coolant to the outside environment.

                                              Evaporator: Transfer heat from the internal environment to the coolant.

                                                  The compressor is the "heart" of the refrigeration system and it is responsible for the circulation of the coolant in the entire refrigeration system.

                                                  When the coolant is liquid, it is in a gaseous state. Check the working simulation of the refrigeration system.

                                                  Environmental rooms reproduce and closely monitor any environment with a precise combination of humidity, temperature and light. Customers

                                                  have the option to choose a multi-temperature, or constant temperature room, which are customized to meet your testing and storage needs.

                                                  Compressors are used in domestic refrigeration, like domestic refrigerators or freezers. It can also be applied to commercial refrigeration, such as

                                                  refrigeration equipment in restaurants, bars, and other commercial facilities.
