Description
Technical Field
[0001] The utility model belongs to the technical field of water heaters, in particular to a flat-plate solar energy and air energy integrated water heater. Background Art
[0002] Solar thermal technology converts solar radiation into heat through solar collectors. Flat-plate solar collectors are one of the most common types and consist of a heat-absorbing plate, a transparent cover, an insulating layer, and an outer shell. When sunlight strikes the collector, the plate absorbs the solar energy and converts it into heat, heating the heat transfer medium, typically water or antifreeze, flowing through the collector.
[0003] An air-source heat pump is a device that extracts low-grade heat from the air and raises it to a higher temperature for use. It consists of four basic components: an evaporator, a compressor, a condenser, and an expansion valve. The operating principle is that the refrigerant absorbs heat from the outside air in the evaporator, increases its pressure and temperature through the compressor, and then releases the heat through the condenser to the water or space to be heated.
[0004] The flat-plate solar energy and air energy integrated water heater is a high-efficiency hot water supply system that combines solar thermal utilization technology and air source heat pump technology. It can give priority to using flat-plate solar energy to provide energy, and use air energy to heat water on cloudy days, reducing dependence on traditional energy. Utility Model Content

At this time, the heated hot water in water storage space 1 flows out through the outlet pipe, and the empty water storage space 2 is replenished with water through the inlet pipe. This reciprocating process can achieve uninterrupted hot water supply without expanding the volume and number of water tanks. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0024] Figure 1 Shows the overall structural diagram of a flat-plate solar and air energy integrated water heater; Figure 1In the embodiment, the flat-plate solar energy and air energy integrated water heater comprises a water tank 100, a medium circulation pipeline 1 400 and a medium circulation pipeline 2 500. Both the medium circulation pipeline 1 400 and the medium circulation pipeline 2 500 have a heat exchange section placed in the water tank 100 and a free section exposed to the outside. The free section of the medium circulation pipeline 1 400 is connected in series with a photovoltaic component 410 and a one-way valve 1 420, and the free section of the medium circulation pipeline 2 500 is connected in series with an air energy collector 510 and a one-way valve 2 520. In the medium circulation pipeline 1 400, the photovoltaic component 410 is used to convert the absorbed solar energy into heat energy and heat the medium flowing in the medium circulation pipeline 1 400. When the medium flowing in the medium circulation pipeline 1 400 passes through the heat exchange section, it can exchange heat with the water in the water tank 100, thereby increasing the temperature of the water in the water tank 100. In the medium circulation pipeline 2 500, the air energy collector is used to heat the medium. The device 510 can heat the medium flowing in the medium circulation pipeline 2 500, and make the medium flowing in the medium circulation pipeline 2 500 exchange heat with the water in the water tank 100 through its heat exchange section; by utilizing the combination of the medium circulation pipeline 1 400 and the medium circulation pipeline 2 500, that is, when there is sufficient sunshine, only the medium circulation pipeline 1 400 is needed to heat the water in the water tank 100, and when it is cloudy, the medium circulation pipeline 2 500 is used to heat the water in the water tank 100. The combination of the two reduces dependence on traditional energy sources; in the above, the setting of the one-way valve 1 420 and the one-way valve 2 520 can force the medium in the medium circulation pipeline 1 400 and the medium circulation pipeline 2 500 to flow in one direction; it should be noted that in the above, the medium circulation pipeline 1 400 uses a pump body to make the medium flow, while the medium circulation pipeline 2 500 uses a compressor to achieve the flow of the medium therein.

The water inlet main pipeline 210 is connected to the water inlet branch pipeline 1 220 and the water inlet branch pipeline 2 230 through a tee. The water inlet branch pipeline 1 220 is connected to the water storage space 120, and a solenoid valve 1 221 is installed on the water inlet branch pipeline 1 220. The water inlet branch pipeline 2 230 is connected to the water storage space 2 130, and a solenoid valve 2 231 is installed on the water inlet branch pipeline 2 230; the water outlet pipe The pipeline 300 includes a water outlet main pipeline 310, a water outlet branch pipeline 1 320 and a water outlet branch pipeline 2 330. The water outlet main pipeline 310 is connected to the water outlet branch pipeline 1 320 and the water outlet branch pipeline 2 330 through a tee. The water outlet branch pipeline 1 320 is connected to the water storage space 2 130, and a solenoid valve 321 is installed on the water outlet branch pipeline 1 320. The water outlet branch pipeline 2 330 is connected to the water storage space 1 120, and a solenoid valve 4 331 is installed on the water outlet branch pipeline 2 330. The water inlet branch pipeline 1 220 of the water inlet pipeline 200 is connected to the water storage space 120 in the first state. In the first state, the solenoid valve 221 and the solenoid valve 321 are opened, and the solenoid valve 231 and the solenoid valve 4 331 are closed. In the second state, the water inlet branch pipe 230 of the water inlet pipe 200 fills the water storage space 2 130 with water and discharges the hot water in the water storage space 2 130 through the water outlet branch pipe 2 330. In the second state, the solenoid valve 121 and the solenoid valve 321 are closed, and the solenoid valve 231 and the solenoid valve 4 331 are opened.That is to say, by controlling the opening and closing of the solenoid valve 1 221 and the solenoid valve 3 321 as well as the solenoid valve 2 231 and the solenoid valve 4 331, the conversion of the water inlet direction and the water outlet direction can be controlled. In the first state, the water storage space 120 serves as the water inlet side and the water storage space 2 130 serves as the water outlet side, that is, the hot water supply side. In the process of supplying hot water to the water storage space 2 130, since the incoming cold water is completely separated by the partition 110, the water supply can be stable. At the same time, the water in the water storage space 120 is The cold water is also being heated. When the hot water in water storage space 2 130 is exhausted, the system switches to the second state. In this state, water storage space 120 becomes the outlet, and water storage space 2 130 becomes the inlet. The heated hot water in water storage space 120 flows out through the outlet pipe 300, while the empty water storage space 2 130 is replenished through the inlet pipe 200. This cycle repeats, achieving uninterrupted hot water supply without increasing the volume or number of water tanks 100.
[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
