A target thermal sensation setter sets target thermal sensations for a finite number of parts into which the occupant is virtually divided. A cabin temperature controller individually controls a cabin air-conditioning unit and an auxiliary heater so that the thermal sensations of the respective parts of the occupant estimated by an occupant thermal sensation estimator fall within a range of the target thermal sensations.

A comfort sensation calculation unit quantitatively calculates comfort sensation of an occupant from an RRI of the occupant A, and a target control value of a thermal environment control device is set based on the comfort sensation of the occupant. Therefore, it is possible to achieve air conditioning control that reflects the comfort sensation of the occupant. When a signal output from the comfort sensation calculation unit and a signal output from the occupant thermal sensation calculation unit do not correspond to each other, the signal output from the comfort sensation calculation unit is corrected, and the target control value is determined.

Vehicle air-conditioning device and vehicle provided with vehicle air-conditioning device

A vehicle seat heater is provided in a vehicle seat. This vehicle seat heater includes a first heat generator, second heat generator, and controller. The first heat generator is disposed in a first area of the vehicle seat supporting an occupant. The second heat generator is disposed in a second area not being in contact with the occupant or being less pressed by the occupant than the first area is. The controller controls current application to the first heat generator in a manner such that a heating temperature zone of the first heat generator is a direct heat transfer temperature zone close to a body temperature of the occupant, and also controls current application to the second heat generator in a manner such that a heating temperature zone of the second heat generator is a radiation heat transfer temperature zone.

A reciprocating compressor of the disclosure includes a cylinder, a piston, a space for compressing gas, a discharge port for discharging the compressed gas from the space, a discharge valve, and a supplying port for supplying liquid that is different in kind from the gas. The cylinder has an axis extending in a direction of gravity. The piston is disposed to be reciprocable along the axis inside the cylinder. The space is constituted above the piston by being surrounded by the piston and an inner peripheral surface of the cylinder. The inner peripheral surface of the cylinder includes a straight portion and a throttle portion. The throttle portion is constituted such that an inner diameter of the cylinder decreases toward the discharge valve.

A vehicle air conditioner comprising a heat pump device including a compressor that compresses refrigerant, first and second heat exchangers disposed inside the vehicle cabin within an interior air-conditioning unit, and a pressure reducing valve. The vehicle air conditioner further comprises an air-conditioning controller which controls the heat pump device and interior air-conditioning unit, an exterior heat exchanger temperature sensor and a degree-of-heating requested detecting section. If the quantity of heat absorbed by the exterior heat exchanger has decreased, the controller operates the heat pump device to operate in a mode in which a refrigerant discharged from the compressor flows through the first and second heat exchangers, bypasses the exterior heat exchanger, and then is sucked into the compressor, and a second mode in which the refrigerant is flow throughs the first heat exchanger and is bypassed around the second and exterior heat exchanger after pressure has been reduced.

A heat pump deviceis operated so as to make a switch between multiple operation modes including a first dehumidification and heating operation mode in which a refrigerant discharged from a compressor is circulated through a downstream interior heat exchanger, a first pressure reducing valve, an upstream interior heat exchanger, and an exterior heat exchangerin this order so that the heat exchangerfunctions as a radiator and the heat exchangerfunctions as a heat absorber, and a second dehumidification and heating operation mode in which the refrigerant discharged from the compressor is circulated through the downstream interior heat exchanger, a second pressure reducing valve, the exterior heat exchanger, and the upstream interior heat exchangerin this order so that the heat exchangerfunctions as a radiator and the heat exchangerfunctions as a heat absorber.
