A method for air conditioning an electric or hybrid vehicle includes preconditioning a high voltage accumulator of the electric or hybrid vehicle. The electric or hybrid vehicle has an interior and the high voltage accumulator is air conditioned with an air-conditioning unit having a determined cooling potential. The high voltage accumulator has a current HVS temperature. The interior has a current interior temperature. During the preconditioning, the high voltage accumulator is supercooled in a preconditioning mode with the air-conditioning unit to an HVS temperature that is below an HVS operating temperature.

There is disclosed an air-conditioning apparatus for vehicle which is capable of selecting an appropriate operation mode while inhibiting the operation mode from being unnecessarily changed, and achieving rapid and stable vehicle interior air conditioning. A controller has respective operation modes of a heating mode, a dehumidifying and heating mode, a dehumidifying and cooling mode, and a cooling mode, and selects and executes these operation modes. The controller has a dehumidifying and heating mode maximum radiator temperature MAP and a dehumidifying and cooling mode maximum radiator temperature MAP. The controller selects an operation mode in which a radiator target temperature TCO is achievable by heat radiation in a radiator 4 with reference to each MAP, on startup or at a time of change of the operation mode.

The present disclosure relates to a system for controlling an air flow rate into a vehicle engine room. The system includes: an air intake port receiving an exterior air at a front portion of the vehicle and supplying the air into the engine room; air ducts formed at both sides of the air intake port and introduce the exterior air into a wheel side in order to improve aerodynamic characteristic; a control valve configured to selectively convey the air flowed in the air intake port into the air ducts; a radiator disposed between the air intake port and the engine room; and a control portion configured to control the control valve based on an operating state of vehicle. The air ducts are selectively communicated with the air intake port and disposed at upstream of the radiator.

A vehicular thermal management system includes: an indoor-air-conditioner disposed in a first vehicle body having a passenger space and including a compressor, a first condenser, an evaporator, a blower, and a refrigerant line; and a component-air-conditioner disposed in a second vehicle body combinable with the first vehicle body and including an electrical component line for cooling an electrical component of the vehicle and a first battery line for cooling a high-voltage battery including a chiller which extends toward the first vehicle body to be disposed behind the evaporator when the first vehicle body is combined with the second vehicle body.

An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. A length of a suction pipe that connects a gas-phase refrigerant outflow port of the ejector module to a suction port of a compressor is set to be shorter than a length of an outlet pipe that connects a refrigerant outflow port of an evaporator to a refrigerant suction port of the ejector module. A pressure loss that occurs when a refrigerant flows in the suction pipe may be set to be lower than a pressure loss that occurs when the refrigerant flows in an outlet pipe.

An aircraft air conditioning system comprises a process air line configured to supply compressed process air provided by a process air source to an air conditioning unit of the aircraft air conditioning system and a trim air line branching off from the process air line upstream of the air conditioning unit and being configured such that trim air flows through the trim air line, the trim air having been branched off from the compressed process air flowing through the process air line. A compressor is arranged in the trim air line and is configured to compress the trim air flowing through the trim air line. A turbine of the aircraft air conditioning system is configured to drive the compressor. A cabin exhaust air line is configured to supply cabin exhaust air discharged from an aircraft cabin to the turbine for driving the turbine.

The present disclosure provides a hybrid intercooler system integrated with an air conditioning system and a method of controlling the same. In accordance with the present disclosure, it is possible to stabilize the temperature of intake air passing through the inlet of an intercooler using a water cooling unit and increase the cooling efficiency of the intercooler using an air cooling unit. Consequently, it is possible to improve engine power and fuel efficiency.

A thermal request mediating device includes a calculation unit configured to calculate amounts of heat for thermal circuits, a mediation unit configured to determine amounts of absorbed heat or amounts of discharged heat which are allocated to the thermal circuits based on amounts of heat transferable between the thermal circuits, and a distribution unit configured to distribute amounts of absorbed heat or amounts of discharged heat to units which are included in each thermal circuit based on the determined amounts of absorbed heat or amounts of discharged heat.

A thermal management method and system in a vehicle include a chiller to cause heat transfer between a coolant loop that defines a path in which a coolant circulates and a refrigerant loop that defines a path in which a refrigerant circulates. The system includes an electronic expansion valve (EXV) in the refrigerant loop to control a flow of the refrigerant into a first part of the chiller, and a coolant pump in the coolant loop to control a flow of the coolant into a second part of the chiller. A controller controls the EXV and the coolant pump based on a target amount for the heat transfer.

A thermal management system includes a refrigerant line including a compressor, a water-cooled condenser, and a cooling core for indoor air conditioning connected to the water-cooled condenser such that refrigerant emerging from the water-cooled condenser is introduced into the cooling core for indoor air conditioning, and a battery line including a high-voltage battery heat exchanging module and a heater core for indoor air conditioning. The battery line is connected to the refrigerant line through the water-cooled condenser in a heat exchangeable manner such that the high-voltage battery heat exchanging module and the heater core for indoor air conditioning are connected in parallel to the water-cooled condenser via a first valve to cause cooling water heated while passing through the water-cooled condenser to be selectively introduced into the high-voltage battery heat exchanging module or the heater core for indoor air conditioning.
