Novel pressure-bearing type hot water system

Abstract

The invention relates to a novel pressure-bearing type hot water system comprising a hot water device, a primary water tank and a secondary water tank; a hot water outlet of the hot water device is connected with the primary water tank, and a cold water inlet of the hot water device is connected with the primary water tank through a first circulating water pump; a hot water supply pipe is arrangedon the primary water tank, a second circulating pump is installed on the hot water supply pipe, the water outlet end of the circulating pump is connected with an electromagnetic valve, a first bypasspipe is arranged on the side, at the water inlet end of the second circulating pump, of the hot water supply pipe, and a first one-way valve is arranged on the first bypass pipe; a second bypass pipeconnected with the primary water tank is arranged on the side, at the water outlet end of the first one-way valve, of the first bypass pipe; a second one-way valve is arranged on the second bypass pipe; and the primary water tank is provided with a water replenishing port for replenishing water, and the secondary water tank is provided with a water outlet for connecting a hot water pipe of a user. The phenomenon that the temperature is suddenly cooled and suddenly heated when the user uses hot water is not easy to appear to the hot water system.

Description

technical field [0001] The invention belongs to the technical field of hot water supply, and in particular relates to a novel pressure-bearing hot water system. Background technique [0002] Heat pump technology is a new type of energy-saving hot water heating method that has attracted much attention this year. Compared with electric water heaters, its energy-saving effect can reach more than 75%. Compared with gas, it will not produce exhaust gas pollution. Therefore, at present, hotels, schools, hospitals, factories and other places with high water demand have used heat pump technology to heat hot water to save costs. At present, many merchants use open stainless steel systems in order to save initial investment. The water pressure of this system is low, it is uncomfortable to use, the water tank insulation effect is poor, and the energy saving is not high. At the same time, as the use time increases, the water tank is prone to water leakage. At the same time, there is al...

Problems solved by technology

At present, many merchants use open stainless steel system in order to save the initial investment. This system has low water pressure, which makes it uncomfortable to use.

At the same time, there is also a method of using a pressure-bearing modular water tank as a hot water storage method, but the installation of the existing solution is relatively complicated, and it is also easy to cause the temperature to fluctuate when using hot water.
