Water-cooled eco-friendly air conditioners can certainly cool workshop spaces—the answer is beyond doubt. Customers often compare water-cooled air conditioners with traditional air conditioners. Since the cooling cost of a water-cooled air conditioner is extremely low—cooling a 100㎡ workshop for one hour requires only 1 kWh of electricity—how does a water-cooled air conditioner achieve cooling? And how effective is its cooling performance?
A water-cooled air conditioner is a direct evaporative cooling unit. It utilizes renewable energy from the natural environment to influence the dry-bulb temperature and humidity of the air. Cool air is obtained through heat exchange between air and water in direct contact, or via a wetted media surface. The advantages of this cooling method are that it is environmentally friendly, has low equipment costs, low energy consumption, and low requirements on the surrounding environment.
The refrigeration process of a water-cooled eco-friendly air conditioner differs from that of a traditional air conditioner. Its air treatment process is essentially a constant-humidity cooling process: after the treated air undergoes constant-humidity cooling, its temperature can be lowered, but its humidity will increase. The sensible heat and latent heat offset each other, resulting in a total heat of zero.
Therefore, when using a water-cooled eco-friendly air conditioner for ventilation and cooling, it can only provide sensible cooling capacity, not total cooling capacity. Moreover, the sensible cooling capacity provided by a water-cooled eco-friendly air conditioner depends on its airflow volume, the wet-bulb temperature depression (difference between dry-bulb and wet-bulb temperatures) of the intake air, and the moisture content of the intake air.
