摘要： A ventilation and air conditioning apparatus for a vehicle includes: a ventilator that sucks air from outside the vehicle; an air conditioner that conditions air inside the vehicle; a duct for fresh outside air that connects the ventilator with the air conditioner so as to supply the air that the ventilator has sucked from outside the vehicle to the air conditioner; and a duct for conditioned air that supplies the conditioned air blown out from the air conditioner to inside the vehicle. The duct for fresh outside air is branched so as to be connected to the duct for conditioned air. With this configuration, even if the operation of the air conditioner is stopped due to, e.g., a leakage of a flammable refrigerant, an amount of ventilation can be secured in the vehicle.

摘要： Heating equipment, including a first heat exchanger, a compressor, a second heat exchanger, and a first expansion valve that decompresses a refrigerant flowing from the second heat exchanger to the first heat exchanger, are connected so as to circulate the refrigerant. A third heat exchanger provides heat of the refrigerant flowing from the second heat exchanger to the first heat exchanger to the refrigerant flowing from the first heat exchanger toward the compressor. An injection circuit merges part of the refrigerant flowing from the second heat exchanger to the first heat exchanger with the refrigerant that is sucked by the compressor. An injection expansion valve is installed in the injection circuit and decompresses the refrigerant flowing in the injection circuit. A fourth heat exchanger is installed in the injection circuit to supply heat of the refrigerant flowing from the second heat exchanger toward the first heat exchanger to the refrigerant flowing in the injection circuit.
