Low temperature control method of high and low temperature humidity and heat test chamber: The refrigeration cycle adopts the reverse Carnot cycle, which consists of two isothermal processes and two adiabatic processes.
The process is as follows:
The refrigerant is compressed to a higher pressure by adiabatic compression of the compressor, and the refrigeration circuit consists of two parts isothermal Processes and It consists of two adiabatic processes.
Raise the temperature of the exhaust gas, and then transfer the refrigerant to the surrounding medium through the heat exchange between the condenser and the surrounding medium.
Cleaning of high and low temperature damp heat test chamber
1. Before operation, impurities inside should be removed. The power distribution room should be cleaned at least once a year. A vacuum cleaner can be used to pick up dust.
The outer packaging must be cleaned at least once a year. When cleaning, first wipe them with soapy water.
2. Put it in a laboratory with a better environment, equipped with appropriate air conditioning or cooling tower, and it can also be stored in a staff-managed laboratory.
3. The water path and humidifier need to be cleaned regularly, because if the water path is not smooth, it will cause scale deposits in the humidifier and cause the humidifier to dry out;
The humidifier can be damaged, so the water circuit and the humidifier must be cleaned regularly.
Clean the condenser every three months. When the surface of the test fabric is dirty or hardened, or the temperature control is completed, the test cloth must be replaced before the temperature and wet-bulb temperature control is erledone.
Test about every three months, wipe the body temperature changes with a clean cloth, wash the test cloth and replace it first
