Environmental Simulation Series Refrigeration Principles

Generally, there are two cooling methods for simulating high and low temperature environments, including air-cooled and water-cooled, depending on different refrigeration methods and the required cooling capacity of the test chamber or laboratory.

Water cooled: Using water as a cooling medium to dissipate heat through a cooling tower; The condenser is generally shell and tube type/plate exchange.

Air cooled: Using natural air as the cooling medium, heat is dissipated through a fan, and the condenser is made of V-shaped aluminum fins and a fan.

Cooling effect:

The specific heat value of water is higher than that of wind, which can lower the condensation point of refrigerant. Therefore, water absorbs more heat efficiently than air in the process of heat transfer. Therefore, the refrigeration effect of water-cooled units is better. With continuous technological research and development upgrades, the refrigeration effect of air-cooled units has also been greatly improved.

Installation and maintenance:

Due to the different transmission media between the two, water-cooled units need to be used together with cooling water towers, water pumps, and cooling water pipes. Air cooled units use air as the transmission medium, so they can be placed in a well ventilated area. The installation is simple and does not require a cooling water tower, which reduces the maintenance cost compared to water-cooled units.
