Compressor and air conditioner

Abstract

The invention provides a compressor. According to the compressor, a low-pressure cylinder, a first high-pressure cylinder and a second high-pressure cylinder are arranged in an overlapped way, and separation plates are arranged between two adjacent cylinders; the first high-pressure cylinder and the second high-pressure cylinder are both arranged at a same side of the low-pressure cylinder or respectively arranged at two sides of the low-pressure cylinder; a lower flange is disposed at the downside of the low-pressure cylinder, the first high-pressure cylinder and the second high-pressure cylinder; the first high-pressure cylinder is inside provided with a first slip sheet, the second high-pressure cylinder is inside provided with a second slip sheet, and the low-pressure cylinder is inside provided with a third slip sheet; the first high-pressure cylinder and the second high-pressure cylinder are arranged in a parallel way and then are connected with the low-pressure cylinder in a serial way; the first high-pressure cylinder or / and the second high-pressure cylinder is / are a capacity-variable cylinder; and the low-pressure cylinder is taken as a first-stage compression cylinder. The invention also relates to an air conditioner. By employing the compressor and the air conditioner disclosed by the invention, the quantity of working cylinders of a multi-cylinder compressor is convenient to adjust.

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...

Problems solved by technology

[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
