Title:
マルチ熱源ヒートポンプ装置
Document Type and Number:
Japanese Patent JP7357324
Kind Code:
B2
Abstract:
To provide an open loop type and direct expansion type heat pump device having low cost and furthermore having improved heat exchange efficiency compared to a closed loop type heat pump device.SOLUTION: A multi heat source-heat pump device includes a freezing cycle in which a compressor 110 compressing refrigerant, a four-way valve 120, an outdoor heat exchanger 130, an expansion valve 140 and an indoor heat exchanger 210 are connected via a refrigerant piping 2, 3. By switching the four-way valve 120, the outdoor heat exchanger 130 functions as a condenser and the indoor heat exchanger 210 functions as an evaporator during cooling operation, and the indoor heat exchanger 210 functions as a condenser and the outdoor heat exchanger 130 functions as an evaporator during heating operation. The multi heat source-heat pump device comprises as the outdoor heat exchanger 130, two heat exchangers i.e. a water refrigerant heat exchanger 131 that is immersed into water in a water reservoir in which water such as groundwater is stored, and an air refrigerant heat exchanger 132 having an air blowing fan.SELECTED DRAWING: Figure 1
