The constant temperature and humidity machine has the functions of heating, cooling, humidification and dehumidification, and can determine the product's ability to withstand high temperature, low temperature and humidity. So by what aspects does the constant temperature and humidity machine control the temperature? Now let the editor of the constant temperature and humidity machine explain this, I hope it can be helpful to everyone.
1. The heating device is the key to control whether the constant temperature and humidity machine needs to be increased; when the controller receives the heating command, it outputs voltage to the relay and provides about 3-12 volts of direct current to the solid-state drive. Its AC terminal is equivalent to the enable line; the contactor also absorbs the voltage across the heater to generate heat, and is driven by the circulating fan to provide heat to the machine for constant temperature heating and machine humidity.
2. Cooling is an important part of the constant temperature and humidity machine, which directly affects the estimation and performance of constant temperature and humidity. It includes four main components: compressor, condenser, throttling device and evaporator. The compressor is the heart of the refrigeration system. It sucks low-temperature and low-pressure gas, turns into high-temperature and high-pressure environment gas, condenses into liquid, and releases a lot of heat. The heat is taken away by the fan. Therefore, the bottom of the machine is produced by hot air, and then a low-pressure liquid is generated by throttling, and then it becomes a low-temperature and low-pressure gas due to evaporation, and then returns to the compressor. The refrigerant absorbs heat in the evaporator, completes the heat-absorbing vaporization process, achieves the purpose of improving the refrigeration research, and completes the process of the constant temperature and humidity machine refrigeration system.
The above two points are all about the temperature control measures of the constant temperature and humidity machine. Thank you for your understanding and support!
