Solar hot water heating system

Abstract

The invention relates to a split type solar hot water heating system. The water supply and heating of the invention adopt a scheme combining non-pressure type with pressure type. The solar hot water heating system comprises a three-container insulating water tank, a solar collector, a control center, a wireless remote control, a circulating pump, an electromagnetic valve, an electric three-way valve, a gas water heater, a heating radiator / heating coil, a check valve, an electric wire, a water pipe and the like, wherein the inside of the three-container insulating water tank is provided with two non-pressure type inner containers and a pressure type inner container; the two non-pressure type inner containers constitute a heating working medium storage area, and the pressure type inner container forms a pressure type hot water storage area. The system of the invention can achieve the effect of supplying water for a pressure-loaded hot water system and has the advantages of simple installation and low cost of the non-pressure type system. In addition, the heat source of the system mainly adopts solar energy and also uses electricity and gas, thus truly realizing an effect of integrating light, electricity and gas. Furthermore, the pipes of the system are convenient to install, the control center has high integration and is convenient for maintenance and management.

Description

technical field [0001] The invention relates to the field of solar hot water heating. More specifically, the present invention relates to a split solar hot water and heating hot water system. Background technique [0002] Faced with the increasing demand of the society for energy-saving and environmental protection facilities, solar water heaters are becoming more and more popular among consumers. [0003] At present, the more common solar water heaters on the market are integrated, that is, the water tank and the heat collector of the solar water heater are manufactured as one. Since the water inlet and outlet pipes are only the same pipe, the gate valve must be closed when bathing, and the existing water in the water tank is used. Taking a bath, the water tank cannot be supplemented with water while taking a bath, which brings inconvenience to the user. [0004] In addition, there are two types of water supply and heating systems for solar water heaters: one is a pressur...

[0003] At present, the more common solar water heaters on the market are integrated, that is, the water tank and the heat collector of the solar water heater are manufactured as one. Since the water inlet and outlet pipes are only the same pipe, the gate valve must be closed when bathing, and the existing water in the water tank is used. When taking a bath, the water tank cannot be replenished while bathing, which brings inconvenience to the user

[0004] In addition, there are two types of water supply and heating systems for solar water heaters: one is a pressure-bearing system, which is very expensive to implement, complicated to install, and troublesome to maintain; the other is a non-pressure-bearing system. Rely on the drop to release the water in the water tank. If the pump is used to pressurize the water supply, the water supply pressure of the system will be unstable.

[0005] In addition, the water in the water heaters currently on the market has to be replaced every day, and the auxiliary electric heating tubes are seriously fouled, which greatly shortens the life; the vacuum tubes will not decrease in efficiency due to scaling
