Solar water heater pressurizing method

Abstract

A solar water heater pressurizing method comprises the steps that a pressurizing device is installed at first, wherein the device comprises a first water control switch, a second water control switch,a first hand-operated three-way valve, a second hand-operated three-way valve, a booster pump, an electric three-way valve, a controller and a connection pipe; when water is fed into a solar water heater, the first hand-operated three-way valve is twisted, the first end of the first hand-operated three-way valve is closed, the second end and the third end of the first hand-operated three-way valve are opened, the third end of the second hand-operated three-way valve is closed, the second end and the first end of the second hand-operated three-way valve are opened, when a solar water box is filled with water, the second hand-operated three-way valve is twisted, the second end of the second hand-operated three-way valve is closed, and the first end and the third end of the second hand-operated three-way valve are opened; after water feeding of the solar water heater, a tap water system is pressurized when a faucet is directly opened for cold water using; and when the water in the solarwater heater is used, the second end of the first hand-operated three-way valve is closed, and the first end and the third end of the first hand-operated three-way valve are opened. The solar water heater pressurizing method has the advantage that three-in-one pressurizing of water feeding, water discharging and tap water of the solar water heater can be achieved.

Description

technical field [0001] The invention relates to a control method, in particular to a three-in-one method of tap water pressurization, upper water pressurization and lower water (hot water) pressurization of a non-pressure-bearing solar water heater. Background technique [0002] Since the solar water heater is a water heater assembled with vacuum heat collecting tubes, it can produce hot water when there is light, which is the most energy-saving. Therefore, in order to save energy and reduce costs, many families install solar water heaters. There are two types of solar water heaters: pressurized and non-pressurized. Due to the high price of pressurized solar energy, most households use non-pressurized solar energy. Since the non-pressurized solar water heater relies on atmospheric pressure to make the water in the water tank flow out when using hot water, because the pressure is small, the water flow is small, and there is no feeling of water flow impact when bathing, so the...

Problems solved by technology

Since the non-pressurized solar water heater relies on atmospheric pressure to make the water in the water tank flow out when using hot water, because the pressure is small, the water flow is small, and there is no feeling of water flow impact when bathing, so the non-pressurized solar water heater is used The solar water heater is not very comfortable when taking a bath; in addition, since the unpressurized solar energy is generally installed on the roof, due to the high installation position, it will be difficult to fill the solar water heater in places with low tap water pressure, which will cause the solar water heater to fail. use

Therefore, if you want to supply water to the solar water heater in a place with low water pressure, you must install a booster device; Install pressurization equipment; Another situation is that generally non-pressure-bearing solar energy can be installed on the roof of multi-storey buildings, generally without secondary water supply, and tap water pressure may be low on higher floors, which cannot be used normally Some equipment such as gas water heaters, water purifiers, etc., therefore also need to install tap water booster equipment

[0003] If two or three sets of pressurization equipment are installed, it will not only increase the cost, but also take up space, and the operation is very troublesome
