Electrical heating water energy storage heating and solar water energy storage heating complementary system

Abstract

The invention relates to the field of heat facilities, in particular to an electrical heating water energy storage heating and solar water energy storage heating complementary system. The electrical heating water energy storage heating and solar water energy storage heating complementary system comprises a PLC system, a solar water heater and an electrical heater. The solar heater is provided with a heat storage water tank, a first water inlet pipe, a first water outlet pipe, a second water inlet pipe and a second water outlet pipe, wherein the heat storage water tank is provided with a water level and water temperature probe, and the second water outlet pipe is provided with a one-way retaining valve. The electrical heater is sequentially connected with a power-driven three-way valve, a water discharging pipe, cooling fins, a water returning pipe and a circulating pump. The power-driven three-way valve is connected with the second water inlet pipe, and the second water inlet pipe is connected with a water complementing pipe. The second water outlet pipe is connected with the water discharging pipe. According to the electrical heating water energy storage heating and solar water energy storage heating complementary system, the solar heater and the electrical heater are combined, complementation is achieved, in daytime, heating is carried out by fully utilizing the solar heat collection water, at night, heating is carried out by fully utilizing the low-price electricity of a coal to electricity policy, the heating cost is extremely low, the effects of bathing, heating, domestic water and the like can be achieved, energy is saved, and high efficiency is achieved.

Description

[0001] (1) Technical field [0002] The invention relates to the field of heating facilities, in particular to a complementary system of electric heating water energy storage heating and solar water energy storage heating. [0003] (2) Background technology [0004] At present, some of the household heating methods are central heating, and a considerable part of them are self-heating through heating equipment such as coal stoves and gas wall-hung boilers. The heating cost is relatively high, and the heating effect cannot reach the required temperature. Many such families have installed solar water heaters, which are useless except for bathing, and solar energy is not fully utilized, resulting in a waste of resources, so there is such a situation: on the one hand, solar energy resources are wasted in vain , On the other hand, the indoor temperature is not up to the requirement. [0005] (3) Contents of the invention [0006] In order to make up for the defects of the prior art...

[0004] At present, some of the household heating methods are central heating, and a considerable part of them are self-heating through heating equipment such as coal stoves and gas wall-hung boilers. The heating cost is relatively high, and the heating effect cannot reach the required temperature.

Many such families have installed solar water heaters, which are useless except for bathing, and solar energy is not fully utilized, resulting in a waste of resources, so there is such a situation: on the one hand, solar energy resources are wasted in vain , on the other hand, the indoor temperature is not up to the requirement
