Title:
WASTE HEAT UTILIZATION HEAT PUMP SYSTEM
Document Type and Number:
Japanese Patent JP2014159928
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a waste heat utilization heat pump system capable of maintaining lubrication of a compressor.SOLUTION: A waste heat utilization heat pump system comprises: a compression type heat pump circuit utilizing a shaft output of a prime mover 2 as a power source of a compressor compressing refrigerant; and an absorption type heat pump circuit utilizing waste heat from the prime mover 2 as a heat source of a regenerator 21 heating absorbent. The waste heat utilization heat pump system is configured such that the refrigerant evaporated in the compression type heat pump circuit is circulated to an absorber of the absorption type heat pump circuit. The waste heat utilization heat pump system includes, at an outlet of the regenerator 21, a separator 23 separating lubrication oil of the compressor and the refrigerant from the absorbent of absorption type heat pump circuit. The waste heat utilization heat pump system is configured such that the lubrication oil of the compressor and the refrigerant separated by the separator 23 are circulated in the compression type heat pump circuit.
