Variable capacity compressors and air conditioners

Abstract

The present application provides a variable capacity compressor and an air conditioner. The variable capacity compressor comprises a compressor body and a gas-liquid separator (10), the compressor body comprises a variable capacity compression cylinder (1), a sliding vane (4) groove is arranged in the variable capacity compression cylinder (1), and the sliding vane (4) A sliding vane (4) is arranged in the groove, and the compressor body also includes a control component, which cooperates with the sliding vane (4) to limit the sliding of the sliding vane (4), or release the restriction on the sliding vane (4). , the gas-liquid separator (10) is connected to the suction port (14) of the variable volume compression cylinder (1) through the suction pipe (12), and the suction pipe (12) is provided with a control valve (11), and the control valve ( 11) The connection or closing of the suction pipe (12) can be controlled to adjust the state of the control component. According to the variable capacity compressor of the present application, the structure is simple, the control of the variable capacity components can be realized outside the cylinder block, and the reliability of the compressor can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a variable capacity compressor and an air conditioner. Background technique [0002] With the improvement of national energy efficiency standards for air conditioners, the energy efficiency requirements for compressors are also getting higher and higher. In order to address climate change in different seasons, since the country implemented the APF energy efficiency standard, the evaluation dimension of compressor energy efficiency has also changed from cooling to cooling and heating. In order to adapt to changes in cooling and heating under different climatic conditions, air conditioners must be in The cooling capacity is low under light working conditions, and the cooling capacity is large under heavy working conditions. In order to solve this problem, a variable capacity compressor has been developed, that is, the compressor operates in two cylinders when a ...

Problems solved by technology

[0003] The currently known variable capacity compressors basically act directly on the control components inside the pump body, and then act on the parts of the pump body to achieve unloading or combination to achieve variable capacity. It is necessary to connect high-pressure pipelines from the system, resulting in complicated pipelines. , the system assembly is difficult, and the high pressure control of the system also affects the efficiency, and at the same time affects the reliability of the compressor and the controller
