ABSTRACT:
An air conditioner has a heating capacity which is increased with a compressor driven by an engine when an outdoor temperature is too low. A work load of the compressor is increased by injecting refrigerant into the compressor via an injecting port. As a result, a load of the engine is also increased so that a coolant temperature is also increased. A large heat radiation from the hot coolant to the indoor air is established at a coolant heat exchanger.
