Title:
COMPOSITE AIR CONDITIONING AND HEATING DEVICE OF A HEAT-SELF-SUFFICIENT TYPE
Document Type and Number:
WIPO Patent Application WO/2012/011656
Kind Code:
A2
Abstract:
The present invention is a composite air conditioning and heating device of a heat-self-sufficient type, consisting of a hot chamber, a heat input and output unit(3), a cold storage unit(8), a heat storage unit(9), and a heat pump system(7), wherein: the hot chamber provides heat to a cold storage tank (8a) and a heat storage tank (9a) and receives the heat of cold and hot water from the cold storage tank (8a) and the heat storage tank (9a); the heat input and output unit (3) is mounted inside the hot chamber and consists of two or more heat exchangers used for both heat absorption and heat radiation in such a way as to allow the hot chamber to be self-sufficient in heat; each of the heat exchangers is connected to the cold storage tank (8a) and the heat storage tank (9a); the cold storage unit (8) consists of the cold storage tank (8a) which stores cold water, a cold water pump (8b) which circulates and provides cold water to a heat pump system (7), and an evaporator outlet duct (8c) through which the cold water provided to the heat pump system (7) flows back into the cold storage tank (8a); the heat storage unit (9) consists of a heat storage tank (9a) which stores hot water, a hot water pump (9b) which circulates and provides hot water to the heat pump system (7), and a condenser outlet duct (9c) through which the cold water provided to the heat pump system (7) flows back into the heat storage tank (9a); and the heat pump system (7) is so configured that the cold water in the cold storage tank (8a) absorbs solar radiant heat through the heat input and output unit (3) and transfers some of the heat to the hot water in the heat storage tank (9a). The composite air conditioning and heating device of a heat-self-sufficient type according to the present invention is highly effective in reducing fuel costs, since the COP thereof has a maximum value of 7 to 15 and the heat efficiency thereof is twice to more than four times higher than that of existing geothermal heat pumps or air heat pumps of which the COP is around 3.5.
