Title:
GAS ENGINE DRIVEN HEAT PUMP
Document Type and Number:
Japanese Patent JP2016191536
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas engine driven heat pump that can supply heat to a cylinder heat exchange section while effectively using waste heat of an engine.SOLUTION: In a gas engine driven heat pump, a cooling water circulation circuit L2 is branched from a first branch portion B1 on the downstream side of a gas engine E, and includes: a first cooling water flow passage L2a for recirculating cooling water in the gas engine E via an auxiliary evaporator H3; and a second cooling water flow passage L2b for recirculating the cooling water in the gas engine E without interposing the auxiliary evaporator H3. The second cooling water flow passage L2b is branched from a second branch portion B2 located downstream of the first branch portion B1, and includes: a radiator side flow passage L2ba for recirculating the cooling water in the gas engine E via a radiator R; and a cylinder side flow passage L2bb for recirculating the cooling water in the gas engine E via a cylinder heat exchange section Hb.SELECTED DRAWING: Figure 1
