Method of operating hybrid air-conditioning system with fast condensing start-up

摘要

A method of operating a hybrid air-conditioning system for fast start-up for controlling the condition of air in a building enclosed space. The method comprises the steps of: (a) turning on the hybrid air conditioning system; (b) passing process air through a first zone of a moisture transfer wheel to raise the dry bulb temperature of the air passing therethrough; (c) passing the process air leaving the first zone of the moisture transfer wheel through a first zone of a heat transfer wheel to lower the dry bulb temperature of the process air passing therethrough; (d) passing regeneration air through a second zone of the heat transfer wheel to raise the dry bulb temperature of the regeneration air passing therethrough and regenerate the heat transfer wheel; (e) heating the regeneration air leaving the second zone of the heat transfer wheel to further raise the dry bulb temperature of the regeneration air leaving the second zone of the heat transfer wheel; (f) passing the heated regeneration air in step (e) through a second zone of the moisture wheel to lower the dry bulb temperature and regenerate the moisture transfer wheel; and (g) passing the air leaving the second zone of the moisture wheel through a recovery evaporator to further lower the dry bulb temperature.
