Three-in-one pressurizing method of feeding water, discharging water and tap water of solar water heater

Abstract

A three-in-one pressurizing method of feeding water, discharging water and tap water of a solar water heater comprises firstly installing a set of pressurizing device which comprises a first water control switch, a second water control switch, a first manual three-way valve, a second manual three-way valve, a pressurizing pump, a motor-driven three-way valve, a controller and a connection tube; screwing the first manual three-way valve to close the first end and open the second end and the third end when water is fed in the solar water heater, closing the third end of the second manual three-way valve and opening the first end and the second end of the second manual three-way valve; screwing the second manual three-way valve to close the second end and open the first end and the third end when the solar water heater is full of water; pressurizing a tap water system by directly opening a faucet to use cold water after water is fed in a solar water tank; and closing the second end and opening the first end and the third end of the first manual three-way valve when the water in the solar water heater is used. The three-in-one pressurizing method has the advantages of achieving three-in-one pressurizing of the feeding water, the discharging water and the tap water of the solar water heater.

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
