<p>PURPOSE:To provide an engine-driven type heat pump device having a cooling water circulation system which is constituted to minimize the number of cooling water pipes extending through a partition wall. CONSTITUTION:In an engine drive type heat pump device, an outdoor machine comprises three chambers, adjoining to each other, consisting of an engine room 7 to contain an engine 5, an outdoor heat-exchanger chamber 14 to contain a radiator 13, and a piping chamber 10 to contain a main accumulator a waste heat recovering apparatus) 8 to heat-exchange with a refrigerant. A cooling water circulation passage running from the engine 5 to the radiator 13 and the main accumulator (a waste heat recovering apparatus) 8 is arranged and after it runs from the engine 5 in the engine room 7 to the piping chamber 10, it is branched into two passages of the one returning to the piping chamber 7 after it runs through the radiator 13 in the outdoor heat-exchanger chamber 14 and the other being joined with one passage in the piping chamber 10 after it runs to the main accumulator (a waste heat recovering apparatus) 8 in the piping chamber 10. Thereafter, the cooling circulation passage is returned to the engine 5 in the engine room 7 to constitute a cooling water circulation system S.</p> |
