Air-conditioning apparatus for vehicle use

摘要: An air-conditioning apparatus for vehicle use which can obtain sufficient heater capacity even in a cold-climate region, utilize an existing unit, combine combustion type with simple assembly operation, and exhaust heat of motor travel automobile heating passenger compartment. The includes refrigeration cycle connecting refrigerant compressor, refrigerant/water exchanger, first pressure-reducer, exterior exchanger annular configuration. Further, hot-water connects the core, exhaust-heat cooler, water pump configuration parallel exchanger. Accordingly, during heat-pump heating, hot water, temperature raised by condensation circulates core so as to required capacity. During fuel heater, region.
