A thermal management system for a vehicle includes a cooling apparatus for circulating a coolant in a coolant line to cool at least one electrical component provided in the coolant line, a battery cooling apparatus for circulating the coolant to the battery module, a chiller for heat exchanging the coolant with a refrigerant to control a temperature of the coolant, a heater that heats an interior of the vehicle using the coolant, and a branch line. A condenser included in the air conditioner is connected to the coolant line so as to pass the coolant circulating through the cooling apparatus.

A vehicle-mounted temperature controller has a first heat circuit and a refrigeration circuit. The first heat circuit has a first radiator exchanging heat with outside air, a first heat exchanger, and a first pump, and configured so that a first heat medium is circulated therethrough. The refrigeration circuit has the first heat exchanger discharging heat from the refrigerant to a first heat medium to make a refrigerant condense, a second heat exchanger absorbing heat to the refrigerant to thereby make the refrigerant evaporate and to cool an object to be cooled, and a compressor, and is configured so that the refrigerant circulates through the first heat exchanger and the second heat exchanger and thereby a refrigeration cycle is realized. When the object to be cooled starts being cooled, the compressor is started up after the first pump is started up.

A method for operating a brushless electric motor of a motor vehicle, particularly an electromotive refrigerant compressor, with two sub-motors arranged in sections and each comprising n-phases, by means of a converter corresponding to the number of phases of the electric motor.

The second switching points are shifted by a first phase angle and the converter is controlled on the basis of the first switching points and the second switching points. The first phase angle is selected such that a resulting current flow over the converter is smaller than a first threshold value. A unit of a motor vehicle, comprising a brushless electric motor is also disclosed.

A vehicle air conditioner includes a heat pump system and an air conditioner ECU that controls the heat pump system. An operation mode of the heat pump system includes an air cooling mode, an air heating mode, a serial dehumidification air-heating mode, a parallel dehumidification air-heating mode, a battery-only cooling mode, and an air-cooling battery-cooling mode. The air conditioner ECU separately sets conditions for permitting cooling of a battery, depending on the operation mode.

Disclosed is a heat pump system for a vehicle, providing for selective heat-exchanging heat energy generated from a coolant with a coolant upon condensing and evaporation of the coolant to control an internal temperature of the vehicle using the heat-exchanged coolant of a low temperature or a high temperature. The heat pump system adjusts a temperature of a battery module by using one chiller that performs heat exchange between a refrigerant and a coolant and improves the heating efficiency of the vehicle using a waste heat of an electrical component and a battery module.

An adsorption system for the production of demineralized water aboard a motor vehicle comprising: a condenser, an evaporator, a first and a second adsorbent bed, each containing adsorbent material. Each adsorbent bed is selectively connectable to the condenser and/or the evaporator by pipes provided with at least one control valve. Each adsorbent bed is selectively and alternately connectable to a supply circuit of a heating source and to a supply circuit of a cooling source via supply valves. The condenser is directly and selectively connectable to the evaporator by a direct branch provided with a relative throttle valve, An inlet valve is arranged along an air inlet branch, and selectively establishes a fluid connection between the air of the environment outside the system and the adsorbent beds, so as to capture water from the external air through an adsorption phenomenon performed by the adsorbent beds and to produce water.

An air-conditioning system including a primary circuit and a secondary circuit is provided. The primary circuit includes a flow of refrigerant, an evaporator and a chiller configured to exchange heat between a coolant and the refrigerant. The secondary circuit includes a heat exchanger in fluid communication with the chiller to receive the coolant. The heat exchanger includes a phase change material in heat exchange relationship with the coolant, such that the coolant exchanges heat with the phase change material to store thermal energy in the phase change material. The air-conditioning system is implemented in a machine in which during an idle-off state, the stored energy in the heat exchanger is discharged to provide an air-conditioning effect.

A control method for a battery cooling system of a vehicle which is provided for controlling temperature of a battery module by using a refrigerant supplied to a chiller in the battery cooling system may include (A) determining, by a controller, whether an air conditioner is operated, while driving or stopping the vehicle in a state where the vehicle is started, (B) controlling, by the controller, a first expansion valve, and detecting, by the controller, the temperature of the battery module when the controller determines that the air conditioner is operated, and (C) determining, by the controller, selective operation of a second expansion valve through determining whether the temperature of the battery module, which is detected through the controlling in (B), is within a predetermined range.
