Abstract

The invention provides a scroll compressor. The scroll compressor comprises a shell, a static scroll plate and a dynamic scroll plate, wherein the static scroll plate is arranged in the shell, the dynamic scroll plate is movably arranged in the static scroll plate, and a first compression cavity and a second compression cavity are formed between the sidewall of the static scroll plate and the sidewall of the dynamic scroll plate. The scroll compressor further comprises an enthalpy increasing channel. The enthalpy increasing channel comprises air inlet channel bodies and air outlet channel bodies which communicate with the air inlet channel bodies. The air inlet channel bodies are formed in the static scroll plate, and the air outlet channel bodies are formed in the dynamic scroll plate. The air outlet channel bodies comprise the first air outlet channel body and the second air outlet channel body, and the first air outlet channel body and the second air outlet channel body independently communicate with the first compression cavity and the second compression cavity correspondingly. A refrigerating agent is continuously injected into the first compression cavity and the second compression cavity through the air inlet channel bodies in an alternate mode. Through the scroll compressor provided by the invention, the problem that normal use of compressors is influenced by enthalpy increasing channel structures under non-enthalpy-increasing working condition in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a scroll compressor. Background technique [0002] As the ambient temperature decreases, the evaporation temperature of the ordinary air source heat pump system decreases. When the condensing temperature remains unchanged, the compression ratio of the compressor increases, the suction specific volume of the compressor increases, and the gas transmission coefficient decreases, resulting in compression efficiency. Rapidly lowered. When the ambient temperature drops below zero degrees Celsius and the evaporating temperature is too low, the increase in the compression ratio of the compressor will cause the discharge temperature to rise and exceed the allowable operating range of the compressor, causing the compressor to start and stop frequently, resulting in the system not working normally. In severe cases, it will cause the compressor to burn out. [0003] In order to solve the pr...
