The working principle of the freezer
Time:2021-08-30 Source:Wuxi Danxiao Machinery Hits:

When the air is cooled to below the dew point temperature, the water vapor in the air will condense into water. Remove the condensed water and reheat it to obtain low-humidity air. The cooling source of air can be the refrigerant, ice water or brine of the freezer. Modern refrigerating dehumidifiers usually use special compressors for refrigerating dehumidifiers for refrigeration. The principle of high-standard refrigerated dehumidifier humidity concept.


Single-stage refrigeration cycle system

Single-stage refrigerators are a widely used type of refrigerators, which can be used in ice making, air conditioning, food refrigeration and industrial production processes. The single-stage refrigeration cycle refers to the four processes of compression, condensation, throttling, and evaporation of the refrigerant in the refrigeration system to complete the cycle of the single-stage refrigeration machine, that is, to achieve the purpose of refrigeration.


Two-stage refrigeration cycle system

The two-stage refrigeration cycle is developed on the basis of the single-stage refrigeration cycle. Its compression process is carried out in two stages. The refrigerant vapor from the evaporator first enters the low-pressure stage cylinder and is compressed to an intermediate pressure, and then enters the high-pressure after intermediate cooling. The stage cylinder is compressed to the condensing pressure and enters the condenser.

Principle of refrigerant operation

The high-temperature gaseous refrigerant entering the condensing coil exchanges heat with water and air sprayed from the outside of the coil through the coil wall. The temperature of the refrigerant gas decreases as the time in the pipe increases, and gradually changes from a gaseous state to a liquid state. With the super strong wind of the fan, the spray water is fully covered on the outer surface of the coil, thereby improving the heat exchange efficiency. After spraying water and air absorb the heat of the coil wall, the temperature rises, and part of the water turns from liquid to gas, taking away a lot of heat from the pipe wall. The moisture in the hot and humid air is intercepted by the water baffle and introduced into the PVC heat exchange layer. , The hot air is discharged. The water in the PVC heat exchange layer is cooled by the fresh air flowing through, the temperature is lowered, and it flows into the water collection tank, and then is sent to the spray system by the water pump to continue to circulate. The water lost to the air is automatically adjusted and supplemented by the water level control device.
