Embodiment Construction

[0008] As shown in the drawings, this embodiment is a high-efficiency energy-saving air conditioner, including an evaporator 1, an indoor fan motor 2, a connecting pipe 3, a stop valve 4, a throttling element 5, a compressor 6, and an air heat exchange condenser 7 And the outdoor fan motor 8, the compressor 6 is a fully enclosed fixed-speed AC motor-compressor, the motor and the compressor are directly connected to drive, and the working conditions of the compressor 6 are set at a condensation temperature of 43°C and an evaporation temperature of 5.7°C , the subcooling temperature is 38°C, the suction temperature is 18°C, and the ambient temperature is 35°C. The indoor fan motor 2 and the outdoor fan motor 8 adopt DC motors, preferably Y04-R type DC brushless motors, and the efficiency can reach 89%. Parts such as the air heat exchange condenser 7, the evaporator 1 and the throttling element 5 are similar to the corresponding parts of the existing similar air conditioner.

Abstract

The invention relates to a type of apartmental air conditioner with air-condition for short. It includes compressor, condenser for heat exchange with air, fan electric machinery and throttling component. The compressor are totally enclosed constant speed alternating current motor--compressor with technical characters that operating condition of the compressor is set up as that condensing temperature is 43 minus or plus 0.5Deg.C, evaporating temperature is 5.7 minus or plus 0.2Deg.C, super-cooling temperature is 38 minus or plus 0.8Deg.C, inspiration temperature is 18 minus or plus 2Deg.C and ambient temperature is 35 minus or plus 1Deg.C. Adopting above-mentioned operating condition as design conditions of compressor can make the compressor achieve the largest efficiency when the air-condition work practically and the air-condition have upper utilization ratio of energy sources.

Description

technical field [0001] The invention relates to a room air conditioner, especially the improvement of the operating conditions of a compressor. Background technique [0002] Currently commonly used single-phase AC fixed-frequency room air conditioners, hereinafter referred to as air conditioners, are mainly composed of fully enclosed fixed-speed AC motor-compressors (hereinafter referred to as compressors), air heat exchange condensers and evaporators, fan motors and air conditioners. components such as flow components. In the national standard GB / T7725 "Room Air Conditioners", the working conditions of fixed-frequency air conditioners with climate type TI are stipulated. In order to improve the energy efficiency of the air conditioner, the known technologies adopted at present are: one is to select a high-energy-efficiency compressor; the other is to enhance the heat transfer technology; the third is to optimize the matching of the fan motor. However, the technical requir...
