Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/064814
Kind Code:
A1
Abstract:
An air conditioning device configured in such a manner that the flow rates of a refrigerant and a heat medium which are subjected to heat exchange are regulated to improve the energy efficiency of the device to thereby reduce the energy consumption of the device.
An air conditioning device provided with: a first heat medium conduit switching device (22) and a second heat medium conduit switching device (23) which are equipped with a refrigerant circulation circuit (A) having flow restriction devices (16) for respectively regulating the flow rates of refrigerants flowing to inter-heat medium heat exchangers (15), and also with a heat medium circulation circuit (B) having the inter-heat medium heat exchangers (15) and a utilization heat exchanger (26) which exchanges heat between a heat medium and air, the first and second heat medium conduit switching devices (22, 23) being located on the inlet side and the outlet side of the heat medium in the utilization heat exchanger (26), the first and second heat medium conduit switching devices (22, 23) mixing or distributing, by adjusting the degree of opening of the heat medium conduit switching devices, the heat media relating to the inter-heat medium heat exchangers (15); and a control device which, in a total cooling operation mode or a total heating operation mode, controls the degree of opening of the heat medium conduit switching device of at least on the inlet side or the outlet side which adjusts the amount of heat exchange in each of the inter-heat medium heat exchangers (15).
