Network pressure-superposed household cold/hot water supply system
The invention discloses a network pressure-superposed household cold/hot water supply system. The system mainly comprises a backflow preventer, a steady-flow tank, a negative-pressure eliminator, water supply pumps, a hot water circulating pump, a displacement heat exchanger, a temperature control valve, a safety valve, a hot water supply pipe, a cold water supply pipe, a hot water return pipe and a control cabinet, wherein the water inlet of the steady-flow tank is directly connected in series with a tap water inlet pipe; the negative-pressure eliminator is mounted on the steady-flow tank; a teletransmission pressure gauge is arranged on the steady-flow tank; the water outlet of the steady-flow tank is connected with the water supply pump through a pipeline; and the number of the water supply pumps is 2-4, all of the water supply pumps are connected in parallel, the water outlet main pipe of the water supply pumps are divided into two paths for water supply, one path is a cold water supply pipe connected with a user, and the other path is a water replenishing pipe connected with the displacement heat exchanger. The network pressure-superposed household cold/hot water supply system has the benefits that original pressure on the tap water inlet pipe can be fully utilized, the functions of heating, hot water circulation and the like can be achieved, and the network pressure-superposed household cold/hot water supply system has the advantages of saving energy and water, occupying a small space, lowering the investment, being high in automatic control degree and the like when applied to an indoor secondary water supply system to supply both cold water and hot water.
