Abstract

The invention discloses a multi-split air-conditioning system and a control method. The system comprises a compressor, an evaporator, a condenser and a super-cooler, wherein a refluxing end of the super-cooler is used for realizing refluxing to the compressor via a refluxing pipeline; a super-cooling pipeline and an enthalpy increasing pipeline are also connected in parallel between the refluxing pipeline and the compressor, wherein the super-cooling pipeline and an exhausting pipeline of the evaporator are connected to a low-pressure air sucking end of the compressor after being jointed with each other; the enthalpy increasing pipeline is connected to a medium-pressure air sucking end of the compressor; moreover, the system also comprises a switching device for controlling opening or closing of the super-cooling pipe and/or the enthalpy increasing pipeline. The multi-split air-conditioning system disclosed by the invention has the advantages of overcoming the defects of poor energy conservation, low energy efficiency and poor user comfort in the prior art and realizing the beneficial effects of good energy conservation, high energy efficiency and good user comfort.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a multi-connected air conditioning system and a control method. Background technique [0002] At present, the vast majority of domestic on-line external unit products generally use ordinary frequency conversion high-pressure cavity scroll compressors, that is, non-enthalpy-increasing scroll frequency conversion compressors. Compared with enthalpy injection frequency conversion scroll compressors, the compressors have the same frequency Disadvantages of low capacity, low energy efficiency of the same capacity, high high-frequency exhaust temperature, and low heating capacity under low-temperature conditions. [0003] In addition, the country has clearly put forward the requirement of "energy saving and emission reduction", and it has been legalized and institutionalized. The relevant national multi-line energy efficiency standard requirements and the competitivene...
