Cooling System

The  cooling system is the most economical and effective cooling method for large-scale greenhouses. The system has the advantages of simple equipment, low cost, low power consumption, large cooling capacity, and reliable operation. It is also a heat prevention and cooling facility commonly used in large-scale agricultural production buildings in various countries around the world. The system equipment cost is only one-seventh of the air-conditioning equipment, and the operating cost is only one-tenth of the air-conditioning. The system can be widely used in agricultural buildings such as greenhouses, livestock and poultry houses, and high-temperature workshops, theaters, and other buildings of hundreds to thousands of square meters for heat prevention and cooling.

The cooling system uses the principle of converting sensible heat in the air into latent heat when water evaporates to cool down. When unsaturated air and free water surface come into contact, the water vapor partial pressure of the free water surface is higher than that of the unsaturated air, so the liquid surface water vapor evaporates. When water evaporates into water vapor, it absorbs a large amount of sensible heat, which causes the air temperature to drop. The whole process is a heat exchange process in which the sensible heat in the air is converted into the latent heat of water vapor.
