摘要： An isolation mounting arm for use with an expansion tank has a passageway with a first end portion, a second end portion, and a medial portion located between the first end portion and the second end portion with the drain port located at the terminal end of the second end portion. A first tee is located in the first end portion with oppositely disposed first and second ports. A second tee is located in the second end portion, with oppositely disposed fourth and fifth ports. A first valve member is coupled to the first port, a second valve member is coupled to the second port, and a third valve member is located adjacent to the drain port. An expansion tank is coupled to either the fourth port or the fifth port with a plug coupled to the other port.

摘要： A system produces domestic hot water and includes a tank having top and bottom portions and containing heat storing fluid, and a tapping unit including first and second tapping coils. The first tapping coil is immersed in the bottom portion of the tank. The second tapping coil is fluidly connected in series to the first tapping coil by a connection pipe, and to the hot water port, and is immersed the top portion of the tank A switching device switches between a first state in which water flows from the cold water port through only first tapping coil to the hot water port, and a second state in which water flows from the cold water port through the first tapping coil and, after flowing through the first tapping coil, through to the second tapping coil to the hot water port.

摘要： A heating and cooling system for use with hot, cold and source fluid circuits. A conduit module couples a heating/cooling module with the fluid circuits. The conduit module includes four three-way valves to communicated fluid from and to the fluid circuits to first and second heat exchangers in the heating/cooling module. The first heat exchanger is used to heat a fluid flow and the second one chills a second fluid flow. The conduit module simultaneously supplies a hot fluid flow to a hot fluid circuit and a cold fluid to a cold fluid circuit. The source fluid is routed by the conduit module. A method of circulating fluid is also disclosed.

摘要： The invention discloses a heat storage water dispenser system, it comprises a heat storage tank, an overflow tank and a two-way valve device, the overflow tank is installed on the top of the heat storage tank, the overflow tank is provided with an exhaust port connected with the atmosphere, and the two-way valve device is installed between the heat storage tank and the overflow tank, an exhaust channel is formed between the two-way valve device and the overflow tank; the heat storage tank is provided with an expansion water channel and a hot water outlet channel, one end of the expansion water channel is connected with the heat storage tank, and the other end is connected with the overflow tank. Due to the existence of the expansion water channel and the design of consistent internal and external pressure of the heat storage tank of the present invention, the heat storage water dispenser system does not need to bear pressure in the heat storage tank, the water temperature range can be controlled in the range of 30-95 degrees, and can effectively solve the defects that the water outlet flows out without reason during heating and the water outlet delays when taking water.
