Split air-conditioning systems are indispensable for maintaining comfortable temperatures in shops and offices throughout the summer. Air-conditioning works by using a refrigerant liquid or gas to transport heat from one set of heat transfer coils indoors to a second outdoors connected by small bore copper pipe. Mechanical processes cause the refrigerant to drop in temperature allowing the fluid to carry heat outside the building.
As an energy intensive process it is important to ensure that an air-conditioning system achieves the maximum possible efficiency. By limiting the heat gain to pipework insulation plays a role in this but pipe insulation on air-conditioning systems performs another, more important, role.
Moisture condensing from the air can rapidly accelerate the corrosion of copper air-conditioning pipes. Corrosion diminishes the life of pipework and can be expensive to fix. As such it is essential to prevent condensation occurring on the pipework.
Insulation should be present along the entire length that, in order to prevent condensation, is able to demonstrate the following attributes:
