Abstract: An automotive air conditioner comprises a housing having an air flow passage defined therein. The housing includes mutually opposed side walls between which a part of the air flow passage is defined. A fan is installed in an upstream part of the air flow passage to introduce air into the air flow passage. An evaporator is installed in the air flow passage at a position downstream of the fan. The evaporator is of a stack type including a plurality of flat tube elements which are stacked on one another. Every adjacent two of the flat tube elements leave therebetween a clearance which has inlet and outlet sides. The evaporator is postured in such a manner that the flat tube elements extend between the mutually opposed side walls of the housing having the inlet sides of the clearances of the flat tube elements directed upstream toward the fan.

Abstract: An air conditioning apparatus preferentially ventilates a space close to a seat and/or a steering wheel on which a passenger directly makes a contact in a passenger compartment while a vehicle is parked. The uncomfortable feeling of a passenger that might occur when he/she is getting into the parked vehicle can be reduced using a small capacity in the air conditioning as compared to the air conditioning apparatus ventilating the whole space in the vehicle.

Abstract: Fresh air exchange is achieved by uncovering two ports which, respectively, allow stale air to leave the trailer through a high pressure duct and fresh outside air to enter the trailer through a low pressure duct. The trailer end of the ducts are connected to the refrigeration unit evaporator section where the evaporator fan provides the pressure differential. The opposite ends of the ducts are connected to a bracket mounted on the refrigeration unit frame and are exposed to the outside fresh air through a hole in the refrigeration unit's grille when the cover over the ducts has been opened by the linear solenoid under the control of the microprocessor.

Abstract: A vehicle air conditioning system is capable of learning preferences for a plurality of passengers, altering control characteristics of air conditioning means based on the results of learning, and automatically controlling the system. The system is capable of adjusting a temperature separately and independently for the left and right sides of a passenger compartment, and stores a temperature setting map of preferences of respective passengers for the Dr side and Pa side. Temperature set points are used for calculating blowing temperatures and determining opening degrees of air mix dampers. If a set point temperature is changed by a manual setting, the temperature-setting map is altered and restored by learning such change, and thus the temperature-setting map can be updated to reflect preferences of each passenger for each of the Dr side and Pa side.

Abstract: When the air blowing amount of a blower 23 is large, a high pressure is controlled so as to be increased higher than when the air blowing amount by the blower 23 is small. By this construction, refrigerant noise is drowned out by air noise and is made difficult to hear. In addition, in general, as a high heating capability is required when the air blowing amount is large and, on the contrary, a high heating capability is not required when the air blowing amount is small, in the event that the high pressure is controlled based on the air blowing amount, the noise attributed to the refrigerant noise, that is felt by the occupants when heating is performed using the hot gas, can be reduced without damaging the sense of being heated.

The discharge duct is disposed below a floor surface of a trunk of the vehicle for causing the air refrigerant discharged from the electricity storing apparatus to flow therethrough. The fan is situated in the discharge duct for discharging the air refrigerant. The fan is disposed outwardly of an interior material provided on a side of the trunk of the vehicle. The arrangement of a cooling apparatus can prevent the operating noise of a fan from entering a passenger compartment and which can facilitate the installation of luggage in a trunk.

Abstract: In an air conditioner for a vehicle, when a target rotation speed of an electric compressor calculated by a target rotation speed calculating means is higher than an upper limit set by an upper limit setting means and a noise level is reduced from a level equal to or higher than a predetermined noise level to a level lower than the predetermined noise level, an inverter controls the compressor to stop for a predetermined period of time and subsequently increase rotation speed to the upper limit. Since the compressor is stopped for the predetermined period of time, the rotation speed of the compressor is controlled without detecting a rotational position of the compressor. Therefore, when the target rotation speed is higher than the upper limit and the noise level is decreased lower than the predetermined noise level, an actual rotation speed of the compressor is immediately decreased.

An auxiliary air conditioning system located exterior of the sleeper compartment is powered by the auxiliary engine. An auxiliary supply duct extends into the sleeper compartment and joins the duct of the sleeper compartment air conditioning unit. A valve operated by air pressure blocks air flow from the sleeper compartment air conditioning unit into the auxiliary duct while in the main position. In the auxiliary position, the valve blocks air flow from the auxiliary duct into the sleeper compartment air conditioning unit.

Abstract: In a seat air conditioning unit for a vehicle seat constructed with a seat cushion and a seat back, when a seat air conditioning operation is performed in a cooling operation of a passenger compartment, a cooling capacity of cool air blown from the seat back is set smaller than a cooling capacity of cool air blown from these at cushion while a passenger sits on the vehicle seat. Further, the cooling capacity of cool air blown from a lower portion of the seat back can be set smaller than the cooling capacity of an upper portion of the seat back. Accordingly, even when the cooling operation is continued for a long time while the seat air conditioning operation is performed, the waist portion of the passenger can be prevented from being excessively cooled.

Abstract: A vehicle air conditioner includes an air conditioning case, a blower fan for blowing conditioned air into a passenger compartment, and an evaporator disposed in the air conditioning case. The air conditioning case has a cooling opening upstream from the evaporator, so that at least inside air is blown by the blower fan to vehicle electronic units through the cooling opening.

Further, because at least inside air, without being cooled by the evaporator, is blown to the electronic units, the electronic units can be prevented from being excessively cooled. Accordingly, it can restrict the surface temperature of the electronic units from reducing less than a dew point, thereby effectively reducing condensed water on the electronic units.
