What is the refrigeration capability of the display cabinet

One. refrigeration system of refrigerating display cabinet:

In the refrigeration system of the freezer, there are four parts: compressor, condenser, evaporator and capillary tube. The evaporator is installed above the interior of the freezer, other components are installed on the back of the freezer, and refrigerant is provided in the refrigeration system. The refrigerant changes from low-pressure liquid to gas to absorb heat and reduce the temperature in the freezer. Refrigerant that turns gaseous state is inhaled by compressor, rely on compressor to compress it into high temperature and high pressure gas, discharge into condenser again. In the condenser, the refrigerant in the gaseous state continues to heat the surrounding space, gradually liquefying into liquid. The high-pressure liquid must flow through the capillary, throttling and reducing the pressure can slowly flow into the evaporator, maintain the evaporator continues to vaporize, heat absorption and cooling. In this way, the freezer USES electric energy to do work, with the help of refrigerant state change, the heat around the evaporator inside the cabinet into the condenser after the cabinet to release, so repeated cycle, in order to achieve the purpose of refrigeration.

Two.Temperature control device of refrigerated fresh-keeping display cabinet:

The temperature control device of the refrigerated display cabinet is called the temperature controller. The main function is to connect the compressor when the temperature inside the cabinet is too high to make the refrigeration system work, so as to bring down the temperature of the cabinet. When the cabinet temperature drops to the required temperature, the compressor power is cut off.

Three. Freezing capacity of the display cabinet:

The freezing capacity of the freezer is mainly the ability of the freezer to freeze food in 24 hours! There are detailed marks on the nameplate on the back of the freezer. Including star, symbol, star symbol, temperature of freezer (℃), and approximate storage time of food. Four stars are frozen stars, indicating that the freezer has quick-freezing capacity. Freezing degree of freezer cabinet should be heavy and practical, freezing force is an important technical index that measures refrigerating appliance. Freezer and freezer are different, freezer main technical performance is not frozen, however refrigerate fresh. Excessive freezing power will not only unnecessarily increase the use of electricity, but also damage the internal organization and nutritional structure of food. For the person of exquisite color fragrance, last last is the first need that consumer buys freezer ark.
