Scroll compressor

Abstract

The invention discloses a scroll compressor, which comprises a fixed scroll component and a movable scroll component, wherein a spraying passage and a spraying hole are arranged on the fixed scroll component, the spraying passage is an annular passage, the spraying hole is arranged in the annular passage, a floating ring, an O-shaped ring A and an O-shaped ring B are arranged in the annular passage, the position of the floating ring is limited by a high-pressure and low-pressure isolation component, and the floating ring can move in the annular passage and can be fixed by a fastening element. The invention is characterized in that the spraying passage and the spraying hole are formed on the fixed scroll component, the mass of the refrigerating agents in a cavity is continuously increased because of the spraying effect, the exhaust temperature of the compressor is obviously reduced because of the cooling effect of the refrigerating agents, and the compressor can work normally. The sprayed refrigerating agents improve the refrigerating quantity, and improve the capability of the compressor, and at the same time, because the capability improvement is greater than the power improvement, the efficiency of the compressor is obviously improved.

Description

technical field [0001] The invention relates to a compressor, especially a scroll compressor. Background technique [0002] When the ordinary compressor is heating at low ambient temperature, the heating capacity of the air conditioning system will drop rapidly with the drop of the outdoor ambient temperature, while the required heat will rise rapidly with the drop of the outdoor ambient temperature. When the outdoor temperature is very low, The heating capacity of the air conditioning system will be too small to meet the winter heating demand in cold areas. At the same time, as the outdoor ambient temperature decreases, the evaporation temperature will also drop below zero degrees Celsius, and the compressor will increase the suction specific volume and compression ratio. As a result, the exhaust gas temperature rises rapidly, and long-term operation will inevitably cause a sharp decline in compressor performance and insufficient heating capacity, and the wear and tear of m...

As a result, the exhaust gas temperature rises rapidly, and long-term operation will inevitably cause a sharp decline in compressor performance and insufficient heating capacity, and the wear and tear of mechanical parts will increase or even be damaged.
