Thermal Insulation
Thermal Insulation Thermal insulation is used in HVAC to avoided heat loss or heat gain from the duct of pipe. It also avoids condensation on cold surfaces. A heat-insulating material is one which has low thermal conductivity. Eg. 1. Duct carries chilled air from the AC unit to space, Heat loss or gain can change the temperature of the air To avoid heat loss or gain, thermal insulation is used 2. Pipe Chilled water pipe carrying water or refrigerant from one unit to other to avoid Heat loss or gain, thermal insulation is used. Steam is generated in boiler and it is taken to the turbine through the pipe. To reduce heat loss or gain, insulation is used. Required Property on Insulating material 1. Can withstand high or low temperature 2. Should have a long life and can not be easily damaged. 3. Easy to install. 4.Should be economical. 5.Fire resistance. 6. resistance to Ozone and UV. Various material such as asbestos, glass wool, expanded polystyrene, puff, nitrile material is used f
