  "textContent": "An air-conditioner for a vehicle includes a vapor-compression refrigeration cycle, a determination unit and a controller. The refrigeration cycle includes a compressor for compressing refrigerant, an inside condenser for exchanging heat between refrigerant compressed by the compressor and air to be supplied to a passenger compartment to heat the air, an outside heat exchanger for exchanging heat between refrigerant and air outside a passenger compartment, and an inside evaporator for exchanging heat between refrigerant and air to be supplied to a passenger compartment. In addition, the refrigeration cycle is capable of operating an outside-air heat-absorption heating operation in which refrigerant absorbs heat at the outside heat exchanger and refrigerant radiates heat at the inside condenser, and an inside-air heat-absorption heating operation in which refrigerant absorbs heat at the inside evaporator and refrigerant radiates heat at the inside condenser. The determination unit determines whether or not the outside heat exchanger is frozen. The controller changes over the outside-air heat-absorption heating operation to the inside-air heat-absorption heating operation when the determination unit determines that the outside heat exchanger is frozen. According to the air-conditioner, a heating operation can be maintained without increasing drive power for the compressor even when the outside heat exchanger is frozen.",
