I have read the drawings, a pipeline marked two kinds of pipe diameter, I do not know the actual installation is like how can we simply say that the cooling principle?
One for a back, also known as high pressure tube (fine), low pressure pipe (coarse), freon inside, this is the central air-conditioning, or more than one.And the central air conditioning of the water system. You're not talking about that
Specific or to map to see! Cooling principle? Are you talking about cooling towers and cooling water? This has no electricity, still have air cooling, give an appraisal first! Ha-ha
Two copper tubes, one is the high pressure pipe, one is the low pressure pipe, the pipeline inside is the refrigerant;A simple refrigeration cycle:Compression condensation throttling evaporation compressionThe compressor to compress refrigerant of low temperature and low pressure, high temperature and high pressure gas into the cooling air in the condenser to the inside, as the high temperature liquid, through the throttle throttle components, become low temperature liquid into gas at low temperature and low pressure in the evaporator evaporation inside, and then back to the compressor to form a complete refrigeration cycle.
The special copper tube and fittings for the connection of the 1~ outdoor unit and the indoor machine are for connecting indoor and outdoor machines.2~ through the pipe through the cold medium (freon, commonly known as snow species).3~ such as in the refrigeration mode (that is, summer), the indoor machine absorbs the indoor heat (exhaust air conditioning), the snow species into low pressure, medium temperature snow species, after a larger copper tube out to the outdoor machine. You can feel the larger copper tube with your hands and feel colder, and the surface will have water.4~ kinds of snow are out of the copper tube and compressed by the compressor to change high temperature and high pressure. The snow enters into the outdoor heat exchanger (fan rotates).5~ and variable temperature pressure snow snow by another (a small brass) into the room, into the indoor machine through the throttle valve (or a capillary expansion valve, etc.) is the throttle section size is very small, but after the throttle valve because the volume suddenly changed, Yu Shixue the moment will become low temperature and low pressure refrigerant, and endothermic.6~ this completes a refrigeration cycle. In the case of heat cycles, the opposite is true. In this way, you should understand the function of the two copper tubes.7~ two tubes are connected to the indoor machine, the general is thin to the indoor release of cold air medium pipe, coarse absorption room heat exhaust pipe. The difference between the inlet pipe and the outlet pipe is that the inlet pipe is thinner, and there is a capillary or a thermal expansion valve at the back, and the outlet pipe interface is larger.In addition, do not use sharp objects / in the usual course of hard bumps of the two tubes, otherwise in the summer air conditioning refrigerant will break through the leakage of refrigerant leakage formation, the refrigeration air-conditioning is not in use, the air conditioning function will lose the cooling effect.
