Performance optimization of medical unit without condensed water

Studies the cooling and heating rate variation and condensation by changing flow pattern and parameters of air and water entering the unit. The experiment results show that cooling capacity of an unit increases as entering air temperature increases, while decreases as entering water temperature increases, and increases as temperature difference of supply and return water decreases. Whether the unit condensation occurs or not is concern with relative humidity of entering air. The unit can provide more cooling quantity than common units under relatively high water supply temperature, satisfying design demands.
