Compressors and Air Conditioners

Abstract

The invention provides a compressor. A low-pressure stage cylinder, a first high-pressure stage cylinder, and a second high-pressure stage cylinder are stacked. A partition is arranged between two adjacent cylinders. The first high-pressure stage cylinder and the second high-pressure stage cylinder are both Placed on the same side of the low-pressure stage cylinder or on both sides of the low-pressure stage cylinder respectively, the lower flange is placed on the lower side of the low-pressure stage cylinder, the first high-pressure stage cylinder and the second high-pressure stage cylinder; the first high-pressure stage cylinder is set The first sliding vane, the second sliding vane is arranged in the second high-pressure stage cylinder, and the third sliding vane is arranged in the low-pressure stage cylinder; the first high-pressure stage cylinder and the second high-pressure stage cylinder are arranged in parallel, and the parallel first high-pressure stage cylinder and The second high-pressure stage cylinder is connected in series with the low-pressure stage cylinder, the first high-pressure stage cylinder or / and the second high-pressure stage cylinder are variable capacity cylinders, and the low-pressure stage cylinder is used as a first-stage compression cylinder. It also relates to an air conditioner. The compressor and the air conditioner of the present invention can conveniently adjust the number of working cylinders of the multi-cylinder compressor.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a rolling rotor type three-cylinder two-stage variable capacity and enthalpy increasing compressor and an air conditioner. Background technique [0002] As the ambient temperature drops, the specific volume of the refrigerant increases, and the unit suction capacity of the compressor decreases, resulting in a significant drop in the heating capacity of the compressor. Electric auxiliary heating is usually used to increase the heating capacity of the compressor or a two-stage enthalpy increasing compressor to solve the problem of low heating capacity at low temperature. The method of using electric auxiliary heat to increase the heat of the compressor mechanism has low energy efficiency; since the displacement of the ordinary two-stage enthalpy increasing compressor cannot be adjusted, its adaptability to operating conditions is poor. Thermal capacity and energy efficiency, the energy e...

[0002] As the ambient temperature drops, the specific volume of the refrigerant increases, and the unit suction capacity of the compressor decreases, resulting in a significant drop in the heating capacity of the compressor.

Electric auxiliary heating is usually used to increase the heating capacity of the compressor or a two-stage enthalpy-increasing compressor to solve the problem of low heating capacity at low temperature

The method of using electric auxiliary heat to increase the heat of the compressor mechanism has low energy efficiency; since the displacement of the ordinary two-stage enthalpy increasing compressor cannot be adjusted, its adaptability to operating conditions is poor. Thermal capacity and energy efficiency, the energy efficiency of operation under normal working conditions is greatly reduced
