The ground liquid exchanger uses a relatively constant soil temperature at a non-freezing depth (approx. 1.2 to 2 m) of approx. +4 to +8 °C in winter and a temperature of approx. +10 to +14 °C in summer. With increasing depth, the ground temperature increases and approaches a constant value throughout the year.
It is made of REVEL-PEX system cross-linked polyethylene pipe of 16 x 1.8 mm with a PEX connection pipe of 23 x 2.5 mm and a fitting for connecting the hydraulic module. The length of the ED-KZ-RH pipe is optional according to the customer's order.
To determine the pressure losses when antifreeze flows through the ED-KZ-R ground heat exchanger, the selected lengths of the inlets (inlet and return branches of the exchanger) are pressure limiting.
