The present disclosure relates to a thermal dissipation system of an electric vehicle that includes: a heat exchanger arranged at the front part of the electric vehicle for providing heating or cooling to an air conditioning system of the electric vehicle; a first heat sink (220) and a second heat sink (230), which are respectively arranged at the two sides of the front part of the heat exchanger (210); a number of rotatable and adjustable air deflectors (121, 131) for changing the flow direction of the air (250) flowing through the heat dissipation system. Temperature sensors are included within the thermal dissipation system for sensing the working temperatures and the environmental temperatures of a battery pack and a motor of the electric vehicle. Opening and closing states of the air deflectors are adjusted in accordance with data provided by the temperature sensors.

A vehicle air conditioning apparatus 10 includes: a refrigerant circuit 11 in which a compressor 21, a heat source side heat exchanger 23, an expansion device 24, and a load side heat exchanger 25 are connected by pipes; and a controller that performs switching between a heating operation in which refrigerant in the refrigerant circuit 11 circulates and a defrosting operation of the heat source side heat exchanger 23 in which the refrigerant in the refrigerant circuit 11 circulates in a direction opposite to a direction in the heating operation. The controller produces an airflow flowing from the load side heat exchanger 25 into a cabin through a first air outlet 5 in the heating operation, and an airflow flowing from the cabin into the load side heat exchanger 25 through the first air outlet 5 is produced in the defrosting operation of the heat source side heat exchanger 23.

An environmental control system, 20, is described wherein bleed air is cooled by a heat exchanger. A fan, 22, pulls ambient air from a ram inlet duct across at least one heat exchanger, 28, 30, and to an outlet. An air cycle machine drives the fan, 22. The bleed air passes downstream of the at least one heat exchanger, 28, 30, to a compressor, 38, and then drives a first stage turbine, 54. The first stage turbine, 54, has an outlet communicating with a condenser, 58, and then a second stage turbine, 60. An icing control system taps hot air downstream of the compressor, 38. An add heat valve, 102, is selectively moveable between a first position blocking flow from the tap passage, 100, a second position where it passes air from the tap passage, 100, to the condenser inlet, and to a point downstream of the condenser and to the second stage turbine, 60. In a third position, the valve only communicates air from the tap passage, 100, into the condenser.

A the battery warm-up apparatus includes an electric motor (2), a battery (4), an electric generator (6) for charging the battery, an engine (7) for driving the electric generator, a refrigeration circuit (8a) arranged to pass through inside the engine in a manner that a temperature medium flows through an inside thereof, a heat exchanger (9), a battery-heating channel (8b) branched from the refrigeration circuit, arranged to pass through the battery and connected to the refrigeration circuit again, a first switching valve (13) arranged at a first portion of the refrigeration circuit, the battery-heating channel being branched from the refrigeration circuit at the first portion, the first switching valve connecting and disconnecting the battery-heating channel relative to the refrigeratiort circuit, a battery temperature sensor (4a), and a controller (15) for operating the first switching valve on the basis of temperature (T_B) of the battery and for allowing the temperature medium to flow through the battery-heating channel.

A dehumidifier comprises a suction unit (45) which humid air (47) is sucked in, a dehumidifying unit (43) having a chiller (56) and for cooling down the humid air sucked in and for dehumidifying by condensing the moisture in the humid air, a discharge unit (46) having a heat radiator (54) and for heating and discharging dry air (49) as dehumidified at the dehumidifying unit, a refrigerant circulating system (44) for cooling down the humid air at the dehumidifying unit and for heating the dry air at the discharge unit, and a heat exchanger (1) for performing heat exchange between the humid air and the dry air as dehumidified at the dehumidifying unit (43).
