Heat exchangers that save energy by heat exchange between a fresh liquid and waste fluids

An apparatus to preferentially temper a liquid (only heat it, or, only cool it) by heat exchange with a fluid of indeterminate temperature. A tank of the liquid is plumbed to a liquid dispenser such as a water faucet, heater or chiller and has a internal heat exchanger sealed through each end. A drainpipe with a slit sleeve for double-wall safety, passes through the housing with an annular space between and is connected to a supply of fluids. A gasket seals the space forming a conduit for the liquid. One end of the housing extends from the tank for the liquid inlet. The conduit has natural convection holes into the tank controlled by convection valves which are moved by convection allowing convection only in the direction which preferentially tempers the liquid in the tank, regardless of the temperature, volume, rate, and time of flow of fluids. 2. The apparatus of further including a slit sleeve between the drainpipe and the gasket.3. The apparatus of and where the liquid is potable water and the fluid is waste fluid.4. The apparatus of wherein the tank has more that one heat exchanger. The field is heat exchangers that save energy by heat exchange between a fresh liquid and waste fluids.Current drainpipe heat exchangers only work in the ‘continuous flow mode’ when fresh water is being used and drained so both flow through the exchanger at the same time. They don't work in ‘batch flow mode’ where fresh water is used and drained separately, such as in wash machines, tubs, clothes dryers, furnace exhausts and the like. This is because they can't store heat between the fill-drain cycles. The instant invention uses a tank of the fresh water to overcome this problem and is thereby able to exchange more heat with the fresh water. Therefore a great deal of heat energy continues to be wasted adding to global warming and pollution.Hygienic hot water is unique in that, in any given time zone, its use peaks at certain narrow times-of-day: morning, mid-day and evening at which ...
