Abstract

The invention provides a double-rotor two-stage enthalpy-increase compressor, including: an inhalation pipe, a liquid separator, a housing inhalation pipe, a lower flange, a lower cover plate, a compressor housing, an enthalpy-increase pipe, an enthalpy-increase capillary, a low pressure cylinder, a lower roller, an intermediate plate, a high pressure cylinder, an upper roller, an upper flange, a crankshaft, a motor rotor, a motor stator, an exhaust pipe and a low pressure cylinder. The low pressure cylinder and the lower roller therein are disposed on the lower flange; the lower cover plate is disposed at the bottom of the lower flange; the enthalpy-increase pipe is disposed on the lateral of the lower flange; and a silencer expansion chamber is disposed in the lower flange. The invention also provides an air conditioner and a heat pump water heater.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a double-rotor two-stage enthalpy-increasing compressor, an air conditioner and a heat pump water heater. Background technique [0002] HFC, HCFC refrigerants such as R22, R410A, etc., due to the increase in the specific volume at ultra-low temperatures, the unit suction capacity of the compressor decreases, resulting in a significant drop in the heating capacity of the compressor, and due to the decrease in the suction capacity of the refrigerant Small, the unit flow rate is reduced, and the lubrication and cooling effect on the pump body and motor inside the compressor is not good. At low temperatures, the suction and exhaust pressure ratio of the compressor is also large, and the discharge temperature of the compressor is very high. [0003] The inventors have found that there are at least the following problems in the prior art: the enthalpy increase of the ordinary two-cylinder rot...
