High-precision laboratory constant temperature and humidity air conditioning is one of the commonly used equipment in modern laboratories, which can provide a stable temperature and humidity environment for the laboratory to ensure the accuracy and reliability of experimental results. So, how does the high-precision laboratory constant temperature and humidity air conditioner work? Here's a detailed look at how it works.
1. The working principle of constant temperature and humidity air conditioning in high-precision laboratory.
The high-precision laboratory constant temperature and humidity air conditioner accurately controls the indoor temperature and humidity through refrigeration, dehumidification, humidification and other functions. Its core components include evaporators, condensers, compressors, expansion valves, etc.
The refrigeration cycle is one of the core working processes of constant temperature and humidity air conditioning. In the refrigeration cycle, the refrigerant absorbs indoor heat in the evaporator and becomes a low-pressure, low-temperature gas, which is then sucked in by the compressor and compressed into a high-pressure, high-temperature gas. The hot gas is then sent to a condenser, where it transfers heat to the outside air or water, where it condenses itself into a high-pressure liquid. Finally, the high-pressure liquid passes through the expansion valve into a low-pressure, low-temperature refrigerant, which is returned to the evaporator again to complete a refrigeration cycle.
In the process of refrigeration cycle, the function of the evaporator is to absorb indoor heat and reduce indoor temperature; The function of the condenser is to discharge the heat out of the outside and keep the indoor temperature stable.
Dehumidification is done by means of an evaporator in the refrigeration cycle. During the dehumidification process, the evaporator not only absorbs the heat from the room, but also extracts moisture from the air. As the water evaporates, the humidity in the air gradually decreases, thus achieving the effect of dehumidification.
Humidification is done by means of a humidifier. The water in the humidifier is heated and evaporated into water vapor, which is then sent into the room through the air supply system to increase the humidity in the room.
2. The workflow of constant temperature and humidity air conditioning in high-precision laboratory.
1.Temperature control: When the indoor temperature is higher than the set value, the control system of the constant temperature and humidity air conditioner will start the refrigeration cycle, absorb the indoor heat through the evaporator, and reduce the indoor temperature; When the room temperature drops below the set point, the refrigeration cycle is stopped and the room temperature is raised by feeding in warm air.
2.Humidity control: When the indoor humidity is higher than the set value, the constant temperature and humidity air conditioner will start the dehumidification cycle and reduce the indoor humidity through the evaporator; When the indoor humidity falls below the set value, a humidification cycle is initiated to increase the indoor humidity through the humidifier.
3.Air treatment: Constant temperature and humidity air conditioning will also filter, disinfect and other treatments to ensure the freshness and cleanliness of indoor air.
3. Technical characteristics of high-precision laboratory constant temperature and humidity air conditioning.
