1. Refrigerant breathing system of constant temperature and humidity test chamber
The liquid refrigerant in the evaporator of the air conditioner digests and absorbs the heat value of the gas (the gas is cooled and dehumidified) and just begins to evaporate. There is a certain temperature difference between the refrigerant behind and the air, and the liquid refrigerant completely volatilizes into vapor state, and then it is sucked by the refrigeration compressor and contracted (the working pressure and temperature rise). According to the heat value digested and absorbed by the cooler (air cooling/water cooling), the vapor refrigerant solidifies into liquid. According to the throttle valve of the expansion valve (or capillary) of the air conditioner, the refrigerant with low temperature and bottom pressure enters the evaporator of the air conditioner to carry out the whole process of the refrigerant circulation system.
Second, the constant temperature and humidity test box price gas ring system software
The centrifugal fan is responsible for sucking gas from the gas supply outlet. The gas passes through the air conditioner evaporator (cooling and dehumidification), air humidifier and electric heating device (heating), and then is sent into the indoor space required by customers through the positive pressure air supply outlet. The conveyed gas is mixed with the gas in the indoor space and returned to the air supply outlet.
Three, constant temperature and humidity test box price home appliance automation control system software
Comprises a power supply part and an automatic control part.
The power supply part is divided into temperature and humidity control and fault protection part through contactor. Temperature and humidity control is to compare the temperature and humidity of return air with those set by users, and automatically operate the compressor (refrigeration, dehumidification), humidifier, electric heating (heating) and other components to realize automatic control of constant temperature and humidity.
