A heat pump system for a vehicle includes a water cooled condenser that uses a coolant as a heat exchange media and uses waste heat generated from a motor and an electronic device to improve heating performance, efficiency, and dehumidifying performance. A control method is also described.

Heat pump system for vehicle

A controller of a thermal management system for a vehicle controls a first switching valve and a second switching valve to set a battery warming-up state in which a heat medium circulates between a battery-temperature adjustment heat exchanger and a heat-medium heating heat exchanger, and the heat medium does not circulate between a coolant-coolant heat exchanger and a heat-medium heating heat exchanger when both a battery and an engine need to be warmed up. In contrast, the controller controls the first switching valve and the second switching valve to set an engine warming-up state in which the heat medium circulates through between the coolant-coolant heat exchanger and the heat-medium heating heat exchanger while the heat medium does not circulate between a battery-temperature adjustment heat exchanger and the heat-medium heating heat exchanger when a temperature of the battery exceeds a target battery warming-up temperature in the battery warming-up state.

Thermal management system for vehicle

A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.

This vehicle air-conditioning device is provided with: a blower (23) that blows out from a blowout opening into a vehicle cabin; a refrigeration cycle (40, 340) that circulates a refrigerant by means of an electric compressor; an interior heat exchanger (24, 26) that is provided to the refrigeration cycle, and that exchanges heat between the blown air resulting from the blower and the refrigerant; an inside/outside air adjustment device (22) that adjusts the fractions of inside air and outside air included in the blown air; and a blowing control unit (65) that, when the temperature difference between the outside air temperature (Tam) and the target temperature (Tao) of the blowout air blown out from the blowout opening is less than a predetermined value, causes the operation of the blower while the electric compressor is in a halted state, and controls the operation of the inside/outside air adjustment device in a manner so that air containing at least outside air is blown out into the vehicle cabin As a result, if Tao is a temperature close to Tam, the electric compressor is halted and air containing outside air is blown by means of the blower, and so the blowout air can be a temperature close to Tao while effecting a reduction in power consumption

Vehicle air-conditioning device

The present invention is provided with: a first pump (23) and a second pump (24); equipment (31, 32, 34, 36, 37) of which the temperature is to be adjusted; heat exchangers (28, 33, 35); multiple flow paths (11 to 16) including a first pump installation flow path (11), a second pump installation flow path (12), and equipment installation flow paths (13, 14, 15, 16); a first switching unit (21) for selectively connecting the flow paths (11 to 16) with one another and a second switching unit (22) for selectively connecting the flow paths (11 to 16) with one another; and a reserve tank (46) for storing a heat medium. The reserve tank (46) is configured such that the pressure at the liquid surface of the stored heat medium is at a predetermined pressure (for example, atmospheric pressure), and is only connected to one flow path from among the multiple flow paths (11 to 16).

Vehicle heat management system

An electric power unit is composed of a secondary battery, a cooling fan, a fan motor and a case for the secondary battery, the cooling fan and the fan motor. The case has a partition for isolating the fan motor from the secondary battery and cooling fan. A magnetic joint is disposed between the motor and the cooling fan.

In a blower unit for a vehicle air conditioner, an inside/outside air switching door opens an inside air introduction port and closes an outside air introduction port when an inside air introduction mode is set. Plural ribs for irregularly reflecting an air-blowing noise generated by a blower fan are provided on an inner surface of the inside/outside air switching door, and top ends of the ribs are arranged along a main flow of inside air introduced from the inside air introduction port during the inside air introduction mode. Thus, the blower unit effectively reduces a reflected noise on the inner surface of the inside/outside air switching door, and effectively prevents a disturbance noise of the main flow of inside air.

Blower unit with noise-reducing structure for vehicle air conditioner

A bell-mouth ring is formed with a casing to be disposed proximately at an outer radial side of a shroud. The bell-mouth ring has a deflection wall surface for deflecting a flow of air blown out radially outwardly from the centrifugal multi-blade fan and further flowing radially inwardly toward the rotation axis along an inner wall surface of the casing, toward the driving means. In this way, it is possible to suppress air from flowing backward to a suction port through a gap between the shroud and the bell-mouth ring. Accordingly, it is possible to reduce the noise generated by an interference of the air sucked from the suction port with the air flowing backward or by the turbulence of the air flow which is generated in the gap.

Centrifugal blower having a bell-mouth ring for reducing noise

A deodorizing filter for adsorbing malodorous particles in air is disposed at a downstream air side of a circumferential wall of an inside/outside air switching rotary door which opens and closes inside and outside air intake ports. A gap having a predetermined distance is provided between the deodorizing filter and the circumferential wall of the rotary door. The deodorizing filter is rotated integrally with the rotary door. When the rotary door is rotated to open both the outside and inside air intake ports at their intermediately opened positions, the inside air flowing from the inside air intake port directly flows into an outlet side of an inside/outside air switching box, and the outside air introduced from the outside air intake port passes through the gap and the deodorizing filter and flows into the outlet side of the inside/outside air switching box.
