Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system. Background technique [0002] With the continuous development of air-conditioning technology, people's requirements for its environmental protection and energy-saving performance are becoming more and more stringent. Traditional air-conditioners mostly use polluting Freon as the refrigerant, which has a serious pollution effect on the atmosphere. [0003] Carbon dioxide is one of the important components of the earth's biosphere. It is non-toxic, odorless, non-polluting, non-explosive, non-flammable, non-corrosive, OGP=0, GWP=1, friendly to the environment, and has excellent thermophysical properties. For example: the volumetric refrigeration capacity of carbon dioxide is 5 times that of Freon, which can make the compressor smaller; the viscosity is low, and at a relatively low flow rate, it can also form turbulent flow and have good heat tran...
