HYBRID HORIZONTAL DRAINPIPE HEAT EXCHANGER
The present invention is low-cost hybrid horizontal drainpipe heat exchanger that has a large internal diameter and that is best suited for long length application. Several embodiments are disclosed for drainwater heat recovery including a first to ambient air, a second to water with a single-wall-of-separation to the water, and a third having a double-wall-of-separation along with a vent to the ambient. All are based on a hybrid tube wherein a relatively narrow concave copper strip (a tube segment) is engaged in matching curved recesses in a large bore plastic tube segment. In the drainwater-to- fresh water embodiments a pressure chamber for the water supply is created beneath the concave copper strip by means of a thick, elongated gasket that seals against it and against the inner wall of a second plastic tube segment. Inlet and outlet fittings connect between a building's cold water supply and a hot water heater or a faucet. Socket fittings on each end of the hybrid tube heat exchanger provide connection means to standard drainpipe. Because of the low cost and where the length cannot be long, multiple units can be run in parallel or in series or in a zig-zag arrangement.
