A double pipe includes an inner pipe through an interior of which low pressure gaseous cooling medium flows and an outer pipe having the inner pipe in its interior, the outer pipe being configured such that high-pressure liquid cooling medium flows between the inner pipe and the outer pipe, wherein the inner pipe has a plate member that extending in the longitudinal direction so as to partition the interior of the inner pipe into a plurality of chambers. The plate member has a helical shape along the longitudinal direction.

Double pipe

An air-conditioning device includes: a compressor; an outdoor heat exchanger; an evaporating unit configured to evaporate refrigerant a heater unit configured to heat the air by using the heat of the refrigerant a liquid receiver arranged at the downstream side of the outdoor heat exchanger and a restrictor mechanism provided between the heater unit and the outdoor heat exchanger, wherein, in an operation state in which the flow of the refrigerant is restricted by the restrictor mechanism and heat is released in the heater unit, a first operation mode and a second operation mode are switched, the first operation mode being set such that the liquid-phase refrigerant is stored in the liquid receiver and the gaseous-phase refrigerant is guided to the compressor and the second operation mode being set such that the liquid-phase refrigerant stored in the liquid receiver is guided to the evaporating unit.

Air-conditioning device

A vehicle air-conditioning device includes: a first coolant-water circulation path in which coolant water passes through an engine; a second coolant-water circulation path that is communicated with the first coolant-water circulation path and in which the coolant water passes through a vehicle-cabin radiator; a shutting off mechanism that shuts off, when switched to a shut-off state, the communication between the first coolant-water circulation path and the second coolant-water circulation path; and a refrigeration cycle. The refrigeration cycle has: a compressor for compressing cooling medium; a secondary evaporator in which the cooling medium absorbs heat from the coolant water in the first coolant-water circulation path; a secondary condenser that releases heat of the cooling medium that has absorbed the heat at the secondary evaporator to the coolant water in the second coolant-water circulation path; and a secondary expander that decompresses the cooling medium that has passed through the secondary condenser.

Vehicle air-conditioning device

A thermal management system for an electric vehicle that is used in the electric vehicle driven by an electric motor includes a refrigerant loop for an air conditioner, a refrigerant loop for a battery that allows a refrigerant for the battery to circulate among the battery, an evaporating unit and a heating device, and thermal management controlling means that, during charging of the battery, heats the refrigerant for the battery by using the heating device when temperature of the refrigerant for the battery is lower than target temperature of the refrigerant for the battery, and that allows the refrigerant for the air conditioner to circulate and to absorb heat from the refrigerant for the battery, in the evaporating unit, when the temperature of the refrigerant for the battery is higher than the target temperature of the refrigerant for the battery.

Thermal management system for electric vehicle and its control method

A vehicular air conditioning system of the present invention comprises an air conditioning unit which forms an air flow, a first ventthrough which the air flow formed by the air conditioning unit is blown out toward a passenger, a second vent through which the air flow formed by the air conditioning unit is blown out in an upper direction of the vehicle, an air flow blowout switching unit which switches between blowout from the first vent, and blowout from the second vent at predetermined intervals. The air flow blowout switching unit includes a door unit which closes one of the first and the second vents and opens the other vent, and a control unit which controls the closed state and the opened state of the door unit.

Vehicular air conditioning system

A vehicle air conditioning apparatus includes a heater core radiating heat of engine coolant to an air stream to be blown off to a vehicle compartment, a sub condenser operative to radiate heat of compressed refrigerant to the air stream to be blown off to the vehicle compartment for condensing refrigerant, an evaporator operative to allow expanded refrigerant by an expansion valve to absorb heat of the air stream in the vehicle compartment to be evaporated, a variable displacement compressor operative to compress evaporated refrigerant to be discharged to the condenser , a sensor that detects a discharge refrigerant pressure of the compressor , and a compressor control means operative to control a discharge refrigerant volume of the compressor so as to compel a blow-off temperature to lie at a given temperature in response to a detected result of the sensor

Vehicle air conditioning apparatus

A sub-condenser is disposed in a within-vehicle-compartment air passage P , so that the sub-condenser is permitted to receive heat from a heater core
