Problems solved by technology

[0002] Existing solar water heaters mainly include a solar collector and a water storage tank. This solar collector absorbs solar energy and heats cold water, and stores hot water in the storage tank through circulation. This solar energy can only be used when there is sun , if it encounters rainy days or nights, it cannot be used, especially for users who need continuous hot water, it is far from meeting their needs

Embodiment Construction

[0017] Such as figure 1 1. A solar water heating system of the present invention, comprising a thermal oil circuit A, an oil replenishment circuit B and a hot water circulation circuit C.

[0018] The thermal oil circuit A includes a solar heat concentrator 2, a heat source pump 6, an auxiliary heat source 7 and a thermal power input side of a heat pump 8 connected in series in this circuit. The heat pump 8 uses heat input from the thermal power input side as power, and then performs Heating, output hot water from the hot water output side of the heat pump;

[0019] The oil supply circuit B includes an oil storage tank 1, an oil injection pump 4 and an expansion tank 3 connected in series in the circuit. The expansion tank 3 is located above the oil storage tank 1 and the hot oil circuit A. The expansion tank 3 is provided with an oil injection port connected to the oil storage tank 1 And the overflow port and the oil outlet connected to the hot oil circuit A. A liquid leve...

Abstract

The invention relates to a solar hot water system, comprising a hot oil circuit, an oil recharge circuit, and a hot water circulating circuit, wherein the hot oil circuit, the oil recharge circuit, and the hot water circulating circuit are provided with temperature sensors and pressure sensors; an anemometer and a radiation meter are arranged around a solar heat concentrator; the temperature sensors, the pressure sensors, the anemometer and the radiation meter are connected with a controller by signals; the controller is connected with the control switches of the solar heat concentrator and an auxiliary heat source. The system provided by the invention has the advantages that the system is designed reasonably to fully utilize solar energy and increase utilization ratio of solar energy; the system is not influenced by weather so as to ensure the hot water is supplied all the time; the solar heat concentrator and the auxiliary heat source are automatically controlled to switch on / off, so that degree of automation is high, and time and force are saved.

Description

Technical field [0001] The invention involves a solar hot water system. Background technique [0002] The existing solar water heaters mainly include solar heat collectors and water storage tanks. This solar heat collector absorbs solar energy and heats cold water. It is stored in the water storage tank by circulating.If you encounter rainy days or night, you cannot use it, especially for users who need to continue hot water, far from meeting their needs. Invention content [0003] In order to solve the above technical deficiencies, the invention provides a solar hot water system that can make full use of solar energy and provide continuous hot water. [0004] The invention is achieved through the following measures: [0005] A solar hot water system of the present invention, including: [0006] Thermal oil circuit, including the input side of the solar calorie concentrator, thermal source pump, auxiliary thermal source and thermal pump in the circuit; [0007] The oil replenish...
