Embodiment 2

[0085] The single-stage and double-stage compression work and switching principle of Embodiment 2 and Figure 14 The same as shown, the difference lies in the structure of the liquid distributor and the arrangement of the liquid reservoir. The liquid distributor 1a of the second embodiment is a double-pipe liquid distributor, that is, the liquid distributor 1a has two air outlet pipes, 2a and 2b respectively, and the first air outlet pipe 2a communicates with the refrigerant suction port 504 of the second cylinder 50, The second air outlet pipe 2b constitutes the first air inlet pipe of the three-way valve 22, that is, the first air inlet pipe of the three-way valve 22 is the same pipeline as the second air outlet pipe 2b of the liquid separator 1a. The three-way valve 22 also has a second air intake pipe 4a, and the second air intake pipe 4a communicates with the enthalpy increasing pipe 5 through the liquid reservoir 3. The three-way valve 22 also has an air outlet pipe 8a,...

Abstract

The invention provides a two-stage enthalpy-increasing rotor compressor, which includes a shell, a first cylinder, a second cylinder, a pump body partition, a lower flange and a lower flange cover; the first cylinder is provided with a first sliding vane groove to accommodate the first sliding vane, the second cylinder is provided with a second sliding vane groove to accommodate the second sliding vane, the second cylinder is provided with an enthalpy-increasing refrigerant flow hole, and the partition flow hole communicates with the enthalpy-increasing refrigerant flow hole and the first The suction port of the cylinder; it is characterized in that the side of the pump body partition close to the second cylinder also has a partition ventilation groove, and the partition ventilation groove communicates with the partition flow hole. The invention applies the variable capacity control technology to the two-stage enthalpy increasing compressor, which effectively improves the energy saving effect.

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 two-stage enthalpy-increasing compressor: the two-stage rolling rotor compressor is divided into two stages of compression, the first-stage cylinder sucks low-pressure gas, and discharges medium-pressure gas after compression, which enters the second stage through the closed passage (intermediate cavity) in the pump body , as the second-stage air intake, the high-pressure gas discharged after compression enters the shell, and an air supply device is installed in the middle cavity. [0003] The existing double-cylinder variable capacity compressor: the variable capacity adjustment is realized through the unloading of one cylinder. When the cylinder is unloaded, the pressure balance at both ends of the slide is controlled. Unloading; ...
