Problems solved by technology

[0012] However, conventional air conditioners have the following problem: when the compressor needs to be restarted after the compressor is stopped, the inertia of the rotating shaft generated when the compressor is started must be overcome in the initial stage, thus consuming a lot of power.
Moreover, when the compressor is repeatedly started or stopped, the motor and its rotating shaft are easily damaged

Embodiment Construction

[0038] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0039] Such as Figure 4 with Figure 5b Shown, the casing 10 of the variable frequency compressor 3 of the air conditioner of the present invention includes the following structures: the electric part 5, which is made up of the rotor 12 and the stator 11; the compression part 6, which is arranged on the lower side of the electric part. The compression unit 6 also includes the following components: a cylinder 14, which forms a barrel-shaped compression space inside; and a rolling piston 17, which is eccentrically arranged in the compression space and is rotatable.

[0040] The rolling piston 17 is eccentrically connected to the rotating shaft 13 connected to the rotor 12 , and when power is supplied to the electric part 5 , the rotor 12 and the rotating shaft 13 rotate together by a rotating mechanism formed between the stator 11 and the rotor ...

Abstract

This invention discloses a kind of air conditioner controlling method. It includes: first time operation step for judging indoor refrigerating load; step for selectively carrying out starting-stopping operation or changeable capacity operation according to the first step judged refrigerating load.

Description

technical field [0001] The present invention relates to an air conditioner, in particular to a control method for an air conditioner equipped with an inverter compressor. Background technique [0002] In general, an air conditioner is a device that cools or heats indoor air through heat exchange between a refrigerant and indoor or outdoor air. The refrigerant passes through the compressor-condenser-expansion valve-evaporator in sequence, and changes with the thermodynamic cycle process, especially using the heat transfer generated during the state change of the refrigerant to cool or heat the indoor air. The state change occurs in the evaporator and condenser. [0003] A compressor is a device that supplies energy from the outside in order to perform a thermodynamic cycle. As a machine for compressing fluids such as refrigerants and gases, compressors are classified into rotary compressors, reciprocating compressors, and screw compressors according to the way fluids are co...
