New Air -5℃ to -40℃ Low Temperature Air-Cooled Unit (24/7 Operation)

Low-Temperature Air-Cooled Units for Scientific Research

Low-temperature air-cooled units for scientific research are air-cooled refrigeration equipment designed to provide cold sources ranging from -5°C to -40°C for research experiments. At specific temperatures, researchers can read physical data from experiments. The temperature range of the low-temperature air-cooled units introduced by our company is as follows: the new natural air can reach a low temperature of -40°C, operating continuously 24 hours a day; the cold air can reach a low temperature of -90°C, operating continuously 24 hours a day.

Working Principle

According to the principle of the refrigeration system: low-temperature, low-pressure liquid refrigerant undergoes heat exchange with the air flowing into the evaporator. The evaporator absorbs heat from the air, and during the evaporation process, the refrigerant temperature remains unchanged. The liquid refrigerant evaporates into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. After being compressed by the compressor, it becomes a high-temperature, high-pressure gaseous refrigerant and then enters the condenser. In the condenser, it undergoes heat exchange with the natural air drawn in by the cooling fan, discharging the heat of the high-temperature, high-pressure refrigerant out of the unit. The refrigerant then flows out of the condenser through a dryer filter, which removes moisture or other impurities from the refrigerant during the evaporation process. It then enters the expansion valve for expansion and throttling, a process that rapidly lowers the temperature, turning the refrigerant into a low-temperature, low-pressure liquid. The refrigerant after this process re-enters the evaporator for heat exchange and evaporation, thereby completing the entire refrigeration system cycle. This cycle continues continuously, allowing for sustained refrigeration. The cold air is then delivered to the desired cooling destination through the fan via the air outlet.

Unit Selection

Low-temperature air-cooled units for scientific research are available in split and integrated designs. The split type is suitable for space cooling, with an installation method similar to that of household air conditioners: the condenser is installed outdoors, while the main unit is installed indoors. The integrated unit has a wider range of applications, with the main unit for space cooling placed outdoors and connected to air ducts leading indoors. Note: This can be designed for fresh air or recirculated air.
