Through the appropriate way to deal with air, so that the part of the air to reach life and production of the desired temperature, relative humidity, cleanliness and air flow and other environmental parameters required flow rate, which is the air conditioning. Commonly referred to as the air conditioning are household air conditioners and central air conditioning system into two categories. In order to prevent refrigerant cold (heat) loss in the supply tube, return process should be carried out on the steam pipe insulation.

Air conditioning is divided into home air conditioning, commercial air-conditioning and central air conditioning, air conditioning works each are different.

Commercial air conditioning works: usually divided into direct and indirect refrigerant type refrigerant type, the former for the direct purpose of indoor heating and cooling by freon, which is to achieve the effect of indoor heating and cooling for the refrigerant through the indirect effect of water.
Insulation required parts:
(1) The system connecting pipes, such as frozen water pipes, condensate pipes and direct media pipelines.
(2) The system of ventilation ducts, such as back to the pipelines.
(3) parts of the media unit piping and reservoir, indoor terminal equipment.

  

Central air-conditioning host is generally cold (hot) water unit for the system and terminal equipment to produce chilled water air-conditioning and air-conditioning hot water to meet the requirements. Air-conditioning chilled water outlet, return water temperature is 7 ℃, 12 ℃, air conditioning hot water, return water temperature is 60 ℃, 55 ℃.
They are below and above ambient temperature in order to prevent cold, heat loss and condensation, so the system piping and equipment must insulate.
Central air conditioning chilled water (air conditioning hot water) is mostly used seamless steel pipes, galvanized pipe or rigid plastic pipe (PVC or PP-R, PP-C pipe), thermal insulation should be carried out.
Central air-duct air cabinet or transport cold air handling units are mostly made of galvanized steel or glass steel plate, cold temperature of 14 ℃, it should also be heat-insulated.
Central air conditioning condensate water is generally made of galvanized steel and PVC plastic pipe, condensed water temperature is about 18 ℃, it should also be adiabatic. Others directly with super wind pipe insulation or composite duct. Central British cable Roxy products thermal conductivity, high dampness factor, condensation, air terminal and is the preferred unit of thermal insulation material.
