Abstract: A vehicle air conditioner selectively switches one of a cooling mode in which an interior heat exchanger of a refrigerant cycle is operated as an evaporator for cooling air, and a hot-gas heating mode in which the interior heat exchanger is operated as a radiator for heating air. The cooling mode is selected by turning on an air-conditioning switch, and the hot-gas heating mode is selected by turning on a hot gas switch. When both the switches are turned on at the same time, a control unit determines a priority mode having a higher necessity among the hot-gas heating mode and the cooling mode. Specifically, the hot-gas heating mode is automatically set by the control unit when the outside air temperature is lower than a predetermined temperature, and the cooling mode is automatically set by the control unit when the outside air temperature is higher than the predetermined temperature.

Abstract: An air-conditioner is operated under one mode selected from among three modes, i.e., a cooling mode, a heating mode and an air-mixing mode. Conditioned air temperature is controlled by changing a cooling ability in the cooling mode, a heating ability in the heating mode, and a position of an air-mixing door in the air-mixing mode. When the operating mode is switched to the cooling mode or to the heating mode from another mode, the position of the air-mixing door is gradually changed to prevent an abrupt temperature drop or rise until a difference between a target temperature and an actual temperature becomes smaller than a predetermined value.

Abstract: An improved vehicle heating and air conditioning system includes a driver-manipulated temperature selector that is physically coupled to a discharge temperature control mechanism. The selector is operable in a normal mode in which movement of the selector away from a full cold setting produces a corresponding movement of the temperature control mechanism that increases the discharge air temperature by re-heating or a high fuel efficiency mode in which movement of the temperature selector away from the full cold setting allows the temperature control mechanism to remain in a full cold position for a limited range of selector movement while the discharge air temperature is increased by capacity reduction of the refrigerant compressor. The temperature selector is in the form of a rotary knob that is axially shiftable to change modes when the selector is positioned at the full cold setting and spring-biased so that the normal mode is established as the default mode.

Abstract: For cooling and/or heating a machine casing, a method and an arrangement is disclosed in which the machine casing is provided with cooling channels in which pipes are received. Between the pipes and the walls of the cooling channels, a cavity remains through which a cooling medium is circulated. A liquid heat exchange medium is circulated through the pipes. In order to vary the heat energy exchanged per time unit between the pipes and the machine casing, the kind of the medium circulating in the cavities is changed, or its composition is changed, or the flow velocity of the heat exchange medium is varied, or any desired combination of the above measures is realized. Thus, the heat flow, i.e. the exchange of heat energy per time unit, can easily be influenced by the provision of cavities between machine casing and heating or cooling medium by controlling its limiting heat exchange factors, i.e. thermal conductivity and heat transfer resistance.
