The present invention provides a two-stage enthalpy-increase compressor comprising an upper cylinder, a lower cylinder and a lower flange, the upper cylinder, the lower cylinder and the lower flange are successively arranged from top to bottom, a middle separator is arranged between the upper cylinder and the lower cylinder, the lower cylinder is used as a first stage compression cylinder, the upper cylinder is used as a second stage compression cylinder, the lower cylinder is provided with a lower cylinder air intake port and a lower cylinder enthalpy-increase port, the lower flange is provided with an intermediate cavity, the intermediate chamber includes a first cavity and a second cavity, the wall of the first cavity is provided with a first enthalpy-increase port, the first enthalpy-increase port is communicated with the lower cylinder enthalpy-increase port, a second enthalpy-increase port is arranged between the first cavity and the second cavity, the second enthalpy-increase port is provided with a check valve device, and the check valve device is used for one-way circulating of a refrigerant between the first cavity and the second cavity. The present invention further relates to an air conditioner. The two-stage enthalpy-increase compressor and the air conditioner improve the high-pressure stage suction pressure during enthalpy increase, reduce power consumption and improve the performance of the compressor.
Description
technical field [0001] The invention relates to the refrigeration field, in particular to a two-stage enthalpy-increasing compressor with variable intermediate cavity volume and an air conditioner. Background technique [0002] The double-cylinder single-stage compression technology realized by applying the principle of rolling piston compressor is relatively mature, and under the sustainable development theme of high efficiency, energy saving and environmental protection, the double-stage enthalpy-increasing compression technology has been applied to heat pump products, but this technology At present, there are problems of high power and low performance due to the large volume of the lower flange intermediate cavity under the condition of increasing enthalpy. Contents of the invention [0003] In view of the status quo of the prior art, the object of the present invention is to provide a two-stage enthalpy increasing compressor and an air conditioner, which can increase t...
