The constant temperature and humidity test chamber is passed through three interconnected systems: a refrigerant circulation system, an air circulation system, and an electrical automatic control system.
First, the constant temperature and humidity test chamber The refrigerant circulation system: The liquid refrigerant in the evaporator absorbs the heat of the air (the air is cooled and dehumidified) and begins to evaporate, resulting in a certain temperature difference between the final refrigerant and the air. Liquid refrigerant It also completely evaporates into a gaseous state, which is then inhaled and compressed by the compressor (pressure and temperature increase). The gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into a liquid. After throttling through the expansion valve (or capillary tube), the refrigerant turns into a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant circulation process.
Second, the constant temperature and humidity chamber air ring system: the fan is responsible for the air from the air inlet inhalation, air through the evaporator (cooling, dehumidification), humidifier, electric heater (heating) after the air outlet to the user needs space The air sent out is mixed with the air in the space and returned to the return air.
Third, constant temperature and humidity test box electrical automatic control system: including power supply and automatic control part.
The power supply part through the contactor, the compressor, fan, electric add device, humidifier, etc. supply automatic control of the power is divided into temperature and humidity control and fault protection part: temperature and humidity control is through the temperature and humidity controller, Compare the temperature and humidity of the return air with the temperature and humidity set by the user, automatically run the compressor (cooling, dehumidification), humidifier, electric heating (heating) and other components to achieve automatic control of constant temperature and humidity.
