ABSTRACT:
A water-cooled air conditioning system using a regenerative condenser water circuit to reheat the supply air during a dehumidification mode. The air conditioning system may be any type of water-cooled system, including a water source heat pump or water-cooled air conditioner. The reheat circuit circulates water leaving the condenser through the reheat heat exchanger and then returns the water to the condenser inlet. Thus, the reheat circuit ensures that water leaving the condenser is warm enough to provide sufficient reheating for the supply air, regardless of the water source temperature. In addition, a modulation assembly controls the amount of water flowing through the reheat circuit, and thereby its temperature, so that the temperature of the reheated supply air can be maintained within a narrow range.
