Abstract

The invention discloses a pump body assembly, a double-cylinder enthalpy-increasing rotary compressor and a temperature adjusting device. The pump body assembly comprises two cylindrical air cylinders, and the two air cylinders are coaxially arranged; each air cylinder comprises a cylindrical sealed cavity and a rotor arranged in the corresponding cavity, and the rotors correspondingly sleeve eccentric shafts in the cavities; the rotating centers of the eccentric shafts are coaxial with the cavities, and the rotors are always in tangent contact with the cavities in which the rotators are located in the rotating process; the pump body assembly further comprises air supplementing ports, and the air supplementing ports communicate to the air cylinders and are used for supplementing air and increasing enthalpy; and when the volume of a refrigerant constituting each cylinder is Vs, and the thickness of the rotor in each air cylinder is Dc, the following relation that Dc / Vs is larger than orequal to 0.479 and less than or equal to 0.511 is met.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body assembly, a double-cylinder enthalpy increasing rotary compressor and a temperature regulating device. Background technique [0002] With the rapid development of compressor manufacturing technology, compressor manufacturers have introduced a kind of enthalpy-increasing compressor with intermediate air supply. Defects of use. [0003] In the air supplementary enthalpy-increasing rotary compressor, usually the larger the cylinder refrigerant volume of the two-cylinder enthalpy-increasing compressor, the stronger its cooling and heating capacity, but the greater the crankshaft eccentricity required, according to the pump body of the compressor According to the component design specifications, when the cylinder bore and rotor outer diameter are constant, the radial wall thickness of the rotor is inversely proportional to the eccentricity of the crankshaft. The great...
