Chapter 13 - HVAC Applications for PE Pipe

The properties that control this process are based on the ability of the PE pipe to transfer heat either out of, or into, the system. The heat transfer by conduction mechanism that governs this system is the same as any heat exchanger. It is assumed that the ground is at a steady state condition. This type of heat transfer mechanism is What are omega-shaped heat transfer plates?What are omega-shaped heat transfer plates?Omega-shaped heat transfer plates can be snapped over the pipe and will not fall off. They also transfer heat more efficiently than U-shaped plates. In essence, U-shaped plates are simply an economy version of the same product at a lower price.
