Abstract: A self-contained air-conditioning unit which includes an outer box, a base plate slidably removably inserted in the outer box, and a bulkhead on the base plate partitioning the interior of the outer box into an indoor portion and an outdoor portion. A compressor and a condenser are provided adjacent a rear face of the outer box. In the outdoor portion are provided a compresser, and a condenser adjacent the rear face of the outer box. The condenser includes a central portion and left and right curved ends. An evaporator and an indoor fan are provided in the indoor portion. A fan motor drives the indoor fan and an outdoor fan which faces the central portion of the condenser. Air inlets having louvers are provided in the outer box adjacent the curved ends of the condenser. Blow-off ports are provided in the outer box between the outdoor fan and the bulkhead. A slinger ring is disposed on the outdoor fan to scatter condensed water on the base plate.

Abstract: An air conditioner comprising:a compressor for compressing a refrigerant,an outdoor heat-exchanger,a pressure reducing device which controls flow rate of said refrigerant,an indoor heat-exchanger,refrigerant pipes connecting said compressor, said outdoor heat-exchanger, said valve and said indoor heat-exchanger in series,characterized in thatsaid pressure reducing device is a thermal electric type expansion valve comprising a bimetal piece held in a heat insulated manner and to move its moving part responding to an input electric power to a heater to heat said bimetal piece thereby to change flow rate of said valve and,said air conditioner further comprises an electric power output means which issues said input electric power, value of which changes responding to a refrigerant state difference between a first refrigerant state measured by a first measurement element disposed on either one of said indoor heat-exchanger or said outdoor heat-exchanger that is functioning as an evaporator and a second refrigerant
