Problems solved by technology

Its disadvantages are: 1. During the heat preservation cycle, the booster pump is turned on. In order to meet the requirements of simultaneous use by the user group, the power and displacement of the booster pump are generally relatively large. The heat preservation cycle is carried out by using the booster pump. High energy consumption
2. The device fails to solve the problem of how to solve the user's water consumption when the circulating solenoid valve is turned on. If the user turns on the faucet when the circulating solenoid valve is turned on, and uses a large amount of water, only a small amount of return water may pass through the temperature sensor, and the circulating solenoid valve is more expensive. Keeping it open for a long time makes the water pressure at the user end low, which affects the user's use
3. This device is not suitable for central heating. When it is used for central heating, it has the following characteristics: a. When it is used at low peak, only a very small number of users are using it, and the water flow is small; The water flow rate is relatively large; the b pipeline is long, and the drop of the water point may be relatively large
If a large flow circulation pump is used all the time, the energy consumption will be higher

Abstract

The invention relates to a centralized water supply intelligent hot water outlet device and its control method in the technical field of hot water supply equipment. valve, the water outlet pipeline is also connected with a water outlet branch pipe, and a micro water pump, an outlet water flow sensor and a one-way valve are arranged on the water outlet pipe, and the inlet end of the one-way valve is connected with the water storage tank; , the return water branch pipe is provided with a return water flow sensor and a return water branch solenoid valve. 5~20% of the effective flow cross-sectional area. It can insulate pipelines with low energy consumption, and can quickly switch between the state of heat preservation and the state of water.

Description

technical field [0001] The invention relates to the technical field of hot water supply equipment, in particular to a centralized hot water supply device. Background technique [0002] Solar water heaters, air energy water heaters, and gas water heaters are centrally installed on the roofs or roofs of enterprises, hotels or hospitals, and one or more large water tanks supply hot water to each hot water point or room. Point or room hot water outlet valve or the front branch pipe of the hot water outlet valve is connected, because there is always water in the pipe, and the water will not heat up. Constant temperature circulation or constant temperature circulation + timing circulation are commonly used in the industry. The circulation path is: water storage tank-outlet pipe-return water pipe-water storage tank, which can solve the problem of hot water in the main pipe of the water outlet pipe becoming cold. For example: a double-tube instant-on solar water heater is disclosed...
