A vehicle air conditioner includes: a refrigeration cycle in which a refrigerant circulates; a high-temperature cycle in which a first heat medium in liquid form heated by the refrigeration cycle circulates; a low-temperature cycle in which a second heat medium in liquid form cooled by the refrigeration cycle circulates; and a seat that is provided in a vehicle interior and has a warm flow passage and a cold flow passage disposed close to each other. The warm flow passage is provided on the route of the high-temperature cycle, and the cold flow passage is provided on the route of the low-temperature cycle.

Air conditioner for adjusting a temperature of a seat and an interior in a vehicle

This air conditioning device for a vehicle comprises: a refrigeration cycle having a compressor, a condenser, an expansion valve, and an evaporator through which refrigerant sequentially flows; a high-temperature heat medium circuit in which a high-temperature heat medium that has been heat-exchanged with the refrigerant in the condenser circulates; a low-temperature heat medium circuit in which a low-temperature heat medium that has been heat-exchanged with the refrigerant in the evaporator circulates; a connection line for connecting the high-temperature heat medium circuit and the low-temperature heat medium circuit; a plurality of heat exchangers outside the vehicle that allow introduction of the heat medium; and a switching unit capable of switching modes for each of the plurality of heat exchangers outside the vehicle, among a mode for connecting to the high-temperature heat medium circuit, a mode for connecting to the low-temperature heat medium circuit, and a mode for not connecting to either of the high-temperature heat medium circuit and the low-temperature heat medium circuit.

Air conditioning device for vehicle

The area of a back-pressure chamber is increased so that pressing force on a rotational scroll due to back pressure is enhanced to reduce leakage of refrigerant gas through a chip clearance, thereby achieving improved compression efficiency. A scroll compression mechanism configured to form a compression pocket between a fixed scroll and a rotational scrollfacing each other and including a thrust plateconfigured to support a thrust load of the rotational scroll, and a back-pressure supplying mechanismconfigured to supply part of compressed refrigerant gas to a back side of the thrust plateas back pressure are provided. The back-pressure supplying mechanismincludes a back-pressure chamberformed on a thrust surfacefacing the back side of the thrust plate, a back-pressure supplying paththrough which the compressed refrigerant gas is supplied to the back-pressure chamber, and an inner seal ringand an outer seal ringdisposed radially inside and outside, respectively, of the back-pressure chamber. The outer seal ringis provided to be pressed between an inner peripheral surfaceof a housingand an outer peripheral surfaceof the thrust plate

Scroll compressor

A scroll compressor, includes: a scroll compression mechanism including an orbiting scroll, a fixed scroll, and a thrust plate supporting a load of the orbiting scroll in a thrust direction; a back-pressure application mechanism that applies, as back pressure, the refrigerant gas compressed by the scroll compression mechanism to a rear surface of the thrust plate; and a floating amount restriction mechanism that restricts an amount of floating of the thrust plate caused by the back pressure. The floating amount restriction mechanism includes a restriction pin that includes a shaft part and a head part, and locks the thrust plate to the head part to restrict the amount of floating. The shaft part passes through the thrust plate and has a front end part fixed to a front housing, and the head part has a diameter larger than a diameter of the shaft part.

Scroll compressor with controlled pressing force

Provided is a scroll type compressor which reduces variations in the pressing load of a rotating scroll on a fixed scroll, reduces the impact at the start of the compressor and suppresses noises, and can provide excellent durability. A peripheral elastic bodyand a bottom-portion elastic body, which is brought into a compressed condition in the axis line direction of the main shaft, are interposed between a stopper pinon the rotating scroll side and a concave portionon the main shaftside, whereby working errors of each part are compensated and the rotating scroll is constantly brought into close contact with the fixed scroll to maintain the sealing of the compression chamber.
