Air conditioning brass tube function

1, outdoor unit and indoor unit connection of special air conditioning brass tube, fittings joint purpose is to connect the indoor unit and outdoor unit.

2. Refrigerant (Freon, commonly known as snow seed) is passed through the connecting pipe.

3, such as in the refrigeration mode (summer), the indoor machine absorbs the indoor heat (air conditioning), snow into low temperature snow, through a larger copper pipe out of the outdoor machine. You can touch the larger copper pipe with your hand, and it will feel colder and have water on the surface. 4. The snow goes out through the copper tube of the air conditioner and is compressed by the compressor, then the snow becomes high temperature and high pressure and enters the heat exchanger of the outdoor unit to release heat (the fan rotates).

5, then the snow kind of variable temperature in medium voltage by another copper tube (smaller one) to enter indoor, before entering the indoor machine through the throttle valve (capillary tubes or expansion valve), is used to throttle cutting volume is small, but after a throttle valve for volume suddenly become bigger, then the snow kind of instant snow becomes low temperature low pressure, and heat. 6. This completes a cooling cycle. If the heating cycle, on the contrary.

Air conditioning brass tube insulation material characteristics

1. Rock wool tube :(1) rock wool tube is made of basalt as the main raw material and large artificial inorganic fiber by high-temperature melting. It has the advantages of light weight, small thermal conductivity, good sound absorption performance, non-combustion and good chemical stability. (2) It is a new type of heat preservation, heat insulation, sound absorption material. (3) Rock wool pipe also has waterproof, heat preservation, heat insulation and cold insulation performance, has a certain chemical stability, even in the case of damp long-term use will not occur delirium. (4) Because its products do not contain fluorine (F-), chlorine (CL), so rock wool has no corrosion effect on the equipment, for non-flammable material.

2, glass wool tube :(1) sound absorption noise reduction, can prevent resonance. (2) Lightweight material, convenient installation. (3) Mildew resistance, aging resistance, corrosion resistance to ensure a healthy environment. (4) Low hygroscopicity, stable physical properties. (5) low thermal conductivity, strong thermal insulation performance (6) A1 fire, non-flammable. (7) Extrusion resistance and impact resistance.
