Abstract

The invention provides a double-stage enthalpy increasing rotor compressor, including a shell and a low pressure compression part and a high pressure compression part arranged in the shell. The compressor is characterized in that the low pressure compression part includes a first cylinder and a second cylinder, and the first cylinder and the second cylinder are overlapped. The invention increases displacement of the double-stage compressor without changing the diameter of the cylinder, broadens the displacement range of the double-stage compressor under the existing cylinder diameter, and improves the cooling and heating capacity of the double-stage compressor.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a two-stage enthalpy-increasing rotor compressor and an air conditioner and a heat pump water heater with the same. Background technique [0002] Existing rolling rotor type two-stage compressors are generally two-cylinder two-stage compressors. First, the displacement of the two-stage compressors is smaller than that of the two-cylinder single-stage compressors. Second, the balance of rotation is not as good as that of the two-cylinder single-stage compressors. However, there is a big gap between the energy efficiency and heating capacity of the single-stage compressor compared with the two-stage compressor, and the displacement of the two-cylinder two-stage compressor is enlarged. [0003] The existing two-stage rolling rotor compressor is generally two-cylinder two-stage, and the displacement of the two-stage compressor is much smaller than that of the two-cylinder compressor. Now, ...
