    Frozen Refrigeration Units The equipment for the cooling capacity

    Refrigeration unit (Refrigeration unit): Refrigeration unit is composed of refrigeration compressor, condenser, chiller (evaporator), solenoid valve four main components, with oil separator, storage barrels, depending on oil mirror, diaphragm Hand valve return filter and other components.

    1, single-stage refrigeration cycle is the refrigerant in the refrigeration system have been compressed, condensed, throttling, evaporation of the four processes, they completed a single-stage refrigerator cycle, that is, to achieve the purpose of cooling. Car refrigeration unit production and sales manufacturers that single-stage refrigerator is a wider range of applications a class of refrigerators, it can be used in ice, air conditioning, food refrigeration and industrial production processes and so on.

    The evaporator is the equipment of the cooling capacity, the liquid refrigerant evaporates and absorbs the heat of the cooled object; the compressor is the heart of the system, plays the role of sucking, compressing and conveying the refrigerant vapor; the oil separator is used for sedimentation separation After the oil in the refrigerant vapor; the condenser condenses the high temperature refrigerant vapor discharged from the compressor into a saturated liquid; the reservoir is used to store the refrigerant ammonia condensate in the condenser and adjust the refrigerant between the condenser and the evaporator Ammonia liquid supply and demand relationship; ammonia separator is the ammonia gravity supply system in the important ancillary equipment; throttle on the refrigerant from the throttle antihypertensive effect while controlling and regulating the flow of refrigerant into the evaporator, and the The system is divided into two parts: high pressure side and low pressure side.

    2. Refrigeration system consists of evaporator, single-stage compressor, oil separator, condenser, ammonia device, ammonia separator, throttle and other ancillary equipment, etc., through the pipe connected into a closed system. among them,

    Refrigerated truck unit production and sales manufacturers pointed out that the general evaporation temperature at -25 ℃ ~ -50 ℃, should be used two-stage compressor for refrigeration. The refrigeration system consists of evaporators, two-stage compressors, oil separators, condensers, intercoolers, ammonia injectors, ammonia separators, throttle valves and other ancillary equipment, etc., through a pipe connected into a closed system The In the middle and lower cooler, the intermediate cooler uses a small amount of liquid refrigerant to vaporize the endothermic heat at the intermediate pressure, so that the superheated steam discharged from the low pressure stage is cooled to reduce the high temperature level of the suction temperature, and also the high pressure liquid refrigeration The working fluid is cooled.

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

       The high-temperature gaseous refrigerant entering the condensing coil passes through the coil wall and carries out heat exchange with the outside of the coil and the air, and the temperature of the refrigerant gas decreases as the time in the tube lengthens and gradually changes from the gaseous state to the liquid state.

    With a fan of super wind, so that the full coverage of the spray water on the outer surface of the coil, thereby improving the heat transfer efficiency. Spray water and air to absorb the heat of the coil wall after the temperature rise, the car refrigerator production and sales manufacturers said part of the water from the liquid into a gaseous, take away a lot of heat on the wall, hot and humid air in the water cut Live in the introduction of PVC heat exchange layer, hot air discharge. PVC hot exchange layer of water is flowing through the new air cooling, the temperature decreases, into the sump, and then by the pump into the sprinkler system, continue to cycle. The moisture in the air is automatically replenished by the water level control.Frozen Refrigeration Units
