Title:
HEAT PUMP
Document Type and Number:
Japanese Patent JP2015152183
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a new heat pump capable of supplying hot heat and cold heat.SOLUTION: A heat pump includes compression means, condensation means, first expansion means, air heat exchange means, second expansion means and evaporation means. The condensation means performs heat exchange between a refrigerant compressed by the compression means and a heating medium for hot heat supplied to a heating device. The first expansion means can selectively achieve an effective state of decompressing the refrigerant which has passed through the condensation means and an invalid state of substantially not decompressing the refrigerant. The air heat exchange means performs heat exchange between the refrigerant which has passed through the first expansion means and air. The second expansion means can selectively achieve an effective state of decompressing the refrigerant which has passed the air heat exchange means and an invalid state of substantially not decompressing the refrigerant. Then, the evaporation means performs heat exchange between the refrigerant which has passed through the second expansion means and the heating medium for cold heat supplied to a cooling device.
