Abstract: In a vehicle air conditioner having a variable displacement compressor, a control unit calculates a target cooling temperature of air to be cooled by an evaporator, and controls a discharge capacity of the compressor such that a detected air temperature of the evaporator approaches the target cooling temperature. When a deceleration running state of the vehicle is detected, the control unit sets a corrected target cooling temperature lower than the target cooling temperature by a predetermined temperature, and controls the discharge capacity of the compressor such that the detected air temperature approaches the corrected target cooling temperature when the detected air temperature is lower than the corrected target cooling temperature, or controls the discharge capacity of the compressor approximately at the maximum capacity regardless of the corrected target cooling temperature when the detected air temperature is not lower than the corrected target cooling temperature.

Abstract: There is provided a car air conditioner with a high COP, low GWP and high reliability. A simple refrigerant R32 is filled in a refrigerant circuit 1 of the car air conditioner. This simple refrigerant R32 has a high COP and low GWP, but is easily polarized and produces contaminants and sludge. However, these contaminants and sludge hardly block a motor-driven expansion valve 6 or the like due to vibration and impact of a car. Therefore, this car air conditioner has high reliability. Furthermore, since the simple refrigerant R32 is a simple substance, recycling after collection is easy.

Abstract: In an air conditioning apparatus for a vehicle, a distance between the vehicle and a forward vehicle is detected. When the distance is equal to or less than a predetermined distance, a pollutant threshold of a concentration of exhaust gas pollutants is changed from a first level to a second level that is lower than the first level. Then, it is determined whether the concentration of exhaust gas pollutants is equal to or less than the second level. When the concentration is greater than the second level, an inside air mode is selected. When it is determined that the distance is greater than the predetermined distance, it is determined whether the concentration is equal to or greater than the first level of the pollutant threshold. When the concentration is greater than the first level, the inside air mode is selected.

Abstract: In a vehicle air conditioner, a controller calculates a first target post-evaporator temperature for defogging a windshield based on a detection humidity of a humidity sensor, and calculates a second target post-evaporator temperature for defogging the windshield regardless of the detection humidity of the humidity sensor. Then, the controller determines a smaller one between the first and second target post-evaporator temperatures, as a target post-evaporator temperature. Accordingly, even when the humidity sensor detects a humidity lower than an actual humidity of a passenger compartment when a blower operates by a low air-blowing amount, a windshield is prevented from fogging.

Abstract: A refrigeration system and method of refrigeration employ dual refrigeration circuits. Each circuit has an independent compressor, condenser and evaporator. In one refrigeration circuit, the flow of the refrigerant from the condenser to the evaporator is regulated in response to variations in the heat load at the evaporator while, in the other refrigeration circuit, the refrigerant is passed from the condenser to the evaporator at a substantially constant rate of flow. The refrigeration system can be used as a cooling system, including an air conditioning system, and as a heat pump. The evaporator in both circuits may be incorporated within a common heat exchanger as may the two condensers. Additionally, the flow of the refrigerant from the condenser to the evaporator in one refrigeration circuit may be regulated in response to variations in the heat load in the evaporator in that refrigeration circuit by a thermal expansion valve.

Abstract: The air conditioning case (11) includes: a right and a left case body (112, 111) made of resin; and a partitioning plate (113) made of metal, and the partitioning plate (113) is a partitioning portion for partitioning the face blowout opening portion (15) and the defroster blowout opening portion (16) which are formed into one opening portion by the right and the left case body (112, 111).

In the species of FIG. 5, the movable walls are separate valve elements disposed in a circular bore that opens the passages to the ambient surroundings. The actuator includes a spring, for biasing each of the valve elements out of its respective bore, and a holding device that weakens in response to the electrical leakage-warning signal.

Abstract: When a dehumidifying and heating operation is set in an air conditioner, refrigerant is circulated from a compressor to the compressor through a first exterior heat exchanger, a decompression device, an interior heat exchanger, an another decompression device, an inner heat exchanger and a second exterior heat exchanger, in this order. Further, by controlling a throttle opening degree of the another decompression device, a refrigerant temperature in the interior heat exchanger can be set higher than that in the second exterior heat exchanger. Thus, even when the interior heat exchanger is controlled to a temperature to be not frosted, heat can be absorbed from outside air in the second exterior heat exchanger. Accordingly, when an outside air temperature is low, by setting the dehumidifying and heating operation, air to be blown into a compartment can be dehumidified while sufficiently increasing heating capacity.

The difference between the mean radiant temperature and the cabin air temperature provides a measure of the total infrared heat loading on the cabin and is used to increase the cooling capacity of the climate control system.
