Abstract

The embodiment of the invention provides a sliding chute rotary type air-supplementing and enthalpy-increasing compressor and a heat pump system thereof, the sliding chute rotary type air-supplementing and enthalpy-increasing compressor combines the advantages of a reciprocating type fluid machine and a rotary type fluid machine, a working cavity of the sliding chute rotary type air-supplementing and enthalpy-increasing compressor rotates in space while realizing periodic change, and an air suction and exhaust valve is not needed; meanwhile, due to the change of the position of the working cavity, the air supply or exhaust position can be conveniently set, the energy efficiency of the energy system is improved, and the conversion between the compressor and the expansion machine is realized.

Description

technical field [0001] The invention belongs to the technical field of heat pumps, and in particular relates to a chute rotary compressor for supplementing air and increasing enthalpy and a heat pump system thereof. Background technique [0002] Compressor is a device used to compress gas. At present, refrigeration / heat pump compressors are reciprocating compressors and rotary compressors. For reciprocating compressors, due to their mechanical structure limitations, suction valves and Exhaust valve, while the air valve position of medium and small compressors introduces a relatively large clearance volume, which leads to a decrease in the volumetric efficiency of the compressor, especially under high pressure ratio conditions, the compressor efficiency is extremely low, and the ordinary reciprocating The structure of the rotary compressor cannot realize air supply; for the rotary compressor, the compression chamber often introduces rotary motion, resulting in poor sealing ef...

[0002] Compressor is a kind of equipment used to compress gas. At present, refrigeration / heat pump compressors are reciprocating compressors and rotary compressors. For reciprocating compressors, due to their mechanical structure limitations, suction valves and Exhaust valve, while the air valve position of medium and small compressors introduces a relatively large clearance volume, resulting in a decrease in the volumetric efficiency of the compressor, especially under high pressure ratio conditions, the compressor efficiency is extremely low, and ordinary reciprocating The structure of the rotary compressor cannot realize air supplementation; for rotary compressors, the compression chamber often introduces rotary motion, resulting in poor sealing effect. In order to improve the sealing performance of rotary compressors, higher requirements are put forward for the processing of the rotor, and the processing cost is high.

Therefore, when the weather is cold and the ambient heat is low, it will be very difficult to collect heat. Refrigeration / heat pump compressors reflect in the heat pump system that the density of the working fluid sucked by the compressor decreases, resulting in a decrease in the mass flow rate of the working medium that transfers heat, thereby reducing air conditioning. heating capacity of the system
