A geothermal heating and cooling system that uses a water source to provide a heat transfer medium is provided. Elements of the system may include a water source, one or more circulation loops coupled to the water source, a heat exchanger and/or heat pump, and/or a monitoring component configured to monitor for conditions within the system, including leak integrity and water quality.

An evaporator (10) includes a substantially plate-like body member (12) defining an operatively outer surface (14) and an operatively inner surface (16), both surfaces (14, 16) being substantially smooth to inhibit detritus from attaching to the body member (12). The body member (12) is shaped to cause incoming fluid from which heat is to be extracted, in use, to follow an extended, circuitous path past the body member (12) initially along the outer (surface 14) of the body member (12) prior to the fluid impinging on the inner surface (16) of the body member (12).

The instant invention provides for a kit and method of raising inlet temperature of a water supply by utilizing thermodynamic properties associated with difference in temperatures across a gradient and friction. In particular a portion of an inlet supply pipe is disposed in a sewer line such that the opposing flow of waste water and related material interacts with the inlet piping by increasing the temperature thereof.

Integrated systems and methods for onsite wastewater treatment in which a portion of onsite energy demands may be driven by energy harvested from the wastewater. Thermal energy of wastewater may be transferred from an onsite wastewater treatment system to an onsite heat pump to recover thermal energy, at least a portion of which may then be delivered to an onsite energy demand.

A system capable of providing a liquid purification process using heat regenerating or recovering via heat exchangers (“HEs”). The system, in one embodiment, includes a first set of thermal conductive channels (“TCC”), a second set of TCC, and a third set of TCC. The first set of TCC configured in a first HE is arranged in cylindrical shape which is able to surround or enclose a boiler. A function of TCC is to guide a liquid flow traveling through an HE. The second set of TCC configured in a second HE guides a second liquid flow traveling through the second HE. The third liquid flow such as a cold water stream, for example, flows through the third set of TCC adjacent to the first set of TCC and extracts heat from the first liquid flow such as hot purified water via TCC.

The present invention relates to a heat exchanger, an energy recycling system, a fluid distribution manifold and a baffle. The heat exchanger comprising: a first fluid tube through which a first fluid of a first temperature flows; a second fluid tube through which a second fluid of a second temperature flows; a baffle located in at least one of said tubes for moderating flow of at least one fluid passing therethrough; wherein the heat exchanger is configured for communicating thermal energy between the first fluid and the second fluid.

The invention relates to a heat recovery unit to transfer heat from a gray water source discharged from a bath or a shower to preheat fresh cold water supplying a bath, a shower, a boiler system or hot water heater. The heat recovery unit comprises an inner tube, an outer tube, a non-return valve, an anode, deflectors as well as associated piping and fittings. Fresh water from a pressurized public network or well flows through the inner tube while the gray water flows between the inner and outer tubes. The non-return valve installed in the fresh water pipe prevents contamination of the drinking water system. A translucent pipe may be installed in a section of the gray water piping system to detect any leaks. An insulated jacket may be placed around the unit to reduce heat loss. The heat recovery unit may be used in domestic, commercial, industrial and institutional buildings.

A heat exchanger module (1) has a supply pipe portion (4) and a return pipe portion (6) that are connected fluidically to a heat exchanger chamber (2) of the heat exchanger module (1). The supply pipe portions (4) of a plurality of heat exchanger modules (1) can be interconnected fluidically to form a supply pipe (24), and the return pipe portions (6) of a plurality of heat exchanger modules (1) can be interconnected fluidically to form a return pipe portion (26). A feed pipe (12) is arranged inside the supply pipe portion (4), and a heat exchange fluid can be fed via the feed pipe (12) to the supply pipe portion (4).

A plate heat exchanger and methods of construction and use which allow the plate assemblies used in the exchanger to be easily cleaned and maintained and which allow the plate assemblies to be individually and separately removed from the exchanger for cleaning or maintenance while the exchanger remains online and while the other plate assemblies in the plate heat exchanger continue to operate.
