Abstract
A water cooling condensation control system having a water inlet line valve which is opened only when the equipment being cooled is receiving electrical power, an ambient temperature sensor for sensing the dry bulb temperature of the ambient air in the vicinity of the equipment being cooled, an ambient humidity sensor for sensing the relative humidity of the ambient air in the vicinity of the equipment being cooled, a return water temperature sensor for sensing the temperature of the return water in the cooling water return line, a return water flow control valve for controlling the amount of return water, an input water temperature sensor for sensing the temperature of the cooling water provided to the equipment via the cooling water inlet line, and a pump for controllably diverting return water from the return line to the inlet line. A microprocessor controller responsive to the ambient temperature sensor, the ambient humidity sensor and the return water temperature sensor for calculates the dewpoint of the ambient air in the vicinity of the equipment being cooled and controls the return water flow control valve to maintain the return water temperature above the dewpoint within a predetermined range, and further controls the pump to divert return water to the inlet line when the difference between the return water temperature and the inlet water temperature exceeds a predetermined value.
