Constant Humidity Thermostat Industrial Air Conditioner for a Museum
Some places like museums, laboratories, pharmaceutical workshops, precision machining workshops, etc., due to their own complexity, in order to ensure high quality, high precision, high purity and high yield of products, it is necessary to strictly control the temperature and humidity of the ambient air, so the using of special precision constant temperature and humidity air conditioner is particularly important.
The constant temperature and humidity industrial air conditioner includes the following systems.
1. Refrigeration system
The refrigeration system is one of the key parts of the constant temperature and humidity machine. The constant temperature and humidity refrigeration system consists of two parts, a high temperature part and a low temperature part. Each part is an independent refrigeration system.
The evaporation of the refrigerant in the high temperature part absorbs the heat of the refrigerant from the low temperature part and evaporates; the evaporation of the refrigerant in the low temperature part absorbs heat from the object to be cooled (the air in the laboratory) to obtain the cooling capacity.
The high temperature part and the low temperature part are connected by an evaporative condenser, which is both the condenser of the high temperature part and the condenser of the low temperature part.
2. Heating system
Compared with the refrigeration system, the heating system is relatively simple. When the temperature in the conditioned air is lower than the required temperature, the computer controller of the constant temperature and humidity air conditioner will turn on the electric heater, heat the air, and send it to the air-conditioned room through the fan. So the effect of heating is achieved.
3. Control system
The control system is the core of the whole machine, which determines the heating rate, precision and other important indicators. The DUOKAI controller has a large-screen medium-temperature LCD display and RS485 interface to realize monitoring networking, fuzzy intelligent control, and the control accuracy can reach ±1°C and ±5%RH~10%RH.
4. Humidity system
The humidity system is divided into two subsystems: humidification and dehumidification:
The humidification method generally adopts the wet film humidification method. This humidification method has fast humidification speed and sensitive control, especially when the temperature is lowered, it is easy to realize forced humidification.
When the humidity in the conditioned air is greater than the required value, the compressor is started for cooling, the air is cooled to below the dew point temperature through the evaporator, and the moisture in the air is separated out, thereby achieving the effect of dehumidification.
5. Air supply circulation system
The air circulation system generally consists of a centrifugal fan and a motor that drives its operation, which provides the circulation of the air in the indoor unit.
In addition, Duokai constant temperature and humidity air-conditioning units have been widely used in laboratories, control rooms, archives, measuring rooms, food workshops, medicine workshops, precision machining workshops, and other places.
