1. The 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.


2. 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. Generally, when the evaporating temperature is between -25°C and -50°C, a two-stage compressor should be used for refrigeration. The refrigeration system consists of an evaporator, a two-stage compressor, an oil separator, a condenser, an intercooler, an ammonia storage device, an ammonia liquid separator, a throttle valve and other auxiliary equipment, etc., which are connected to each other through a pipe to form a closed system . Among them, the intercooler uses a small amount of liquid refrigerant to vaporize and absorb heat at an intermediate pressure to cool the superheated steam discharged from the low-pressure stage, reduce the suction temperature of the high-pressure stage, and at the same time cool the high-pressure liquid refrigerant.
