    摘要: A heat pump system can be used with a vehicle. A cooling system includes a radiator connected to a cooling line and a first water pump and circulating a coolant along the cooling line so as to cool an electric component. A battery module is provided on a battery cooling line selectively connected to the cooling line through a first valve. And HVAC module includes an internal heater connected to the cooling line through a first connection line, a cooler connected to the battery cooling line through a second connection line, and an opening or closing door provided between the internal heater and the cooler and controlling external air passing through the cooler to be selectively introduced into the internal heater depending on cooling, heating, and heating and dehumidifying modes of the vehicle. A centralized energy is connected to each of the battery cooling line and the cooling line.

    摘要: An air conditioner for a vehicle includes: a compressor that compresses refrigerant for conditioning air in a vehicle cabin and defines a refrigeration cycle; a detecting section that detects a thermal load of air-conditioning in the vehicle cabin; and a control section that controls a rotational speed of the compressor such that the thermal load detected by the detecting section satisfies a predetermined air conditioning request in the vehicle cabin. In case where the air conditioning request is satisfied by controlling the rotational speed of the compressor, the control section periodically switches between a reference rotational speed and a low rotational speed that is lower than the reference rotational speed in order to maintain a state where the air conditioning request is satisfied. The reference rotational speed is a rotational speed within a predetermined range that includes the rotational speed at which the air conditioning request is satisfied.
