As is well known, in order to better control indoor humidity and temperature, many people choose constant temperature and humidity air conditioning units, which can meet the environmental requirements of indoor temperature ± 1 ℃ and relative humidity ± 5%, and can achieve more precise parameter control. They have been used in various industries.

How to choose a constant temperature and humidity air conditioning unit?

1、 Check the accuracy of the equipment

Some environments have relatively high requirements for the accuracy of air conditioning, and accuracy is also an important indicator for judging the quality of air conditioning. The main feature of a constant temperature and humidity machine is precise control of temperature and humidity. Therefore, when purchasing an air conditioner, please check whether the control accuracy of the equipment meets the requirements.

2、 Check device security

Air conditioning units usually run for a long time. If the quality of the parts is poor, it is easy to malfunction during operation, and even bring safety hazards. Therefore, when purchasing, the stability and safety of constant temperature and humidity air conditioning should be considered.

3、 Considering energy-saving and environmental protection performance

Energy conservation and environmental protection are the major trends in social development. Only equipment that meets energy-saving and environmental protection requirements can be considered high-quality equipment, which can reduce operating costs and improve economic benefits.

4、 Consider the convenience of device operation

The design of high-quality constant temperature and humidity air conditioning units is very user-friendly, easy to operate, easy to understand, and does not require excessive maintenance and management, which can save labor costs.

Construction of Constant Temperature and Humidity Air Conditioning Units

Constant temperature and humidity air conditioning is mainly divided into refrigeration system, heating system, dehumidification system, humidification system, and control system.

Refrigeration system: High temperature liquid refrigerant flows out through a filter, is throttled and depressurized by a capillary or expansion valve, and enters the evaporator. Due to the decrease in pressure, the refrigerant continuously absorbs heat from the air in the evaporator and converts it into steam, which is then sucked in by the compressor. The compressed high temperature and high pressure gas enters the condenser, and the heat is continuously carried away by the condenser. The refrigerant is then converted back into a high temperature and low pressure liquid and enters the capillary, continuously circulating.

Heating system: heated by PTC ceramics to reach the set temperature.

Dehumidification system: When the compressor starts, the air temperature passing through the evaporator cools to below the dew point temperature, and water is released.

Humidification principle: By working with an electrode humidifier, water is heated into steam.

Control system: The temperature and humidity are adjusted through a PLC control module, and the parallel port is integrated and controlled through a 485 communication interface.

In addition to these basic functions, additional functions such as purification and sterilization can also be added.

In the process of selecting a constant temperature and humidity air conditioning unit, the first step is to clarify the temperature and humidity requirements for various tasks in laboratory operations, and to find well-known manufacturers and brands to ensure the performance of the product.
