AI Technical Summary

Technical Problem

Existing hot water supply systems cannot effectively regulate water consumption when it fluctuates significantly with the seasons, leading to high equipment investment or water pollution problems. Furthermore, traditional systems suffer from heat waste and equipment idleness during the off-season.

Method used

By introducing an adjustable on/off water supply mode into the hot water supply system, the system configuration can be changed by switching valves, and the hot water supply can be controlled by variable frequency pressurization equipment and temperature detectors, thus enabling flexible use of the hot water tank.

Benefits of technology

Reduce the size of the water tank when hot water usage is low to reduce land occupation and water pollution; pre-store hot water before peak periods to reduce the number of water heaters, lower initial investment, and improve system applicability and efficiency.

Abstract

The utility model discloses a hot water supply system capable of adjusting an opening and closing type water supply mode. The hot water supply system comprises a heat source, a first port, a hot water tank, frequency conversion pressurizing equipment, a second port and a third port, the heat source is connected with the first port through a hot water supply pipeline, a first valve is further arranged on the hot water supply pipeline, and the first valve is arranged close to the first port; a water supply branch is arranged on the hot water supply pipeline and connected with the hot water tank, a second valve is arranged on the water supply branch, the hot water tank is connected with the first port through frequency conversion pressurization equipment, a third valve is arranged between the hot water tank and the frequency conversion pressurization equipment, and a fourth valve is arranged between the frequency conversion pressurization equipment and the first port; the second port is connected with a water inlet pipeline of a heat source through a hot water return pipeline; the third port is connected with a water inlet pipeline of a heat source through a living water supply pipeline. Switching of hot water supply system forms is achieved by controlling opening and closing of the valves, and the problem of applicability limitation of a single system is solved.
