What Is A 2 Pipe HVAC System? A 2-pipe HVAC system is one that uses the same piping alternately for hot water heating and chilled water cooling, as opposed to a 4-pipe system that uses separate lines for hot and chilled water. Two-pipe originated 50 or 60 years ago as a cost-effective way to add
What Is The Main Purpose For Refrigerant Piping Insulation? In refrigeration and air-conditioning applications, insulation needs to be able to protect against condensation. Moisture control is critical to thermal efficiency. If moisture intrudes the insulating material surrounding cold-water piping, thermal efficiency is lost. What is the purpose of refrigerant piping insulation? The right insulation for
What Are The Basic Principles Involved In Refrigeration And Air Conditioning? The absorption of the amount of heat necessary for the change of state from a liquid to a vapor by evaporation, and the release of that amount of heat necessary for the change of state from a vapor back to the liquid by condensation
