PURPOSE:To reduce an amount of engine cooling air and dispense with a water jacket by spraying air condensed water generated in a heat pump evaporator provided with a compressor driven by an engine onto the engine together with outside air. CONSTITUTION:A heat pump evaporator 1 is provided with a compressor 3 having an engine 2 as a drive source and provided on the lower part with a drain receiver 4. A drain pump 7 is attached to a drain sprayer 5 provided on the tip with a drain nozzle 6 communicating to the upstream near the engine 2. Air condensed water generated in the heat pump evaporator 1 is accumulated in the drain receiver 4 and if necessary sprayed from the drain nozzle 6 to the engine 2. The drain water and cooling air from a cooling fan 8 cool the engine together. Thus, the amount of cooling air for the engine is substantially reduced to dispense with a water jacket for water-cooling. |
