Description

Indirect heat exchange flat panel solar water heating system with tankless heating

technical field

The utility model relates to the technical field of solar water heaters, in particular to a flat solar hot water system capable of indirectly heating water in a water storage tank through an instant heating device.

Background technique

Traditional solar water heaters usually pass the water in the water storage tank directly into the flow channel of the heat collector to exchange heat with the heat collector, and it is easy to form scale on the inner wall of the flow channel of the heat collector, which affects the service life of the solar heat collector , and reduce the heat transfer efficiency of the collector. Since the water in the water storage tank is both the heated medium and the heat exchange medium, it is impossible to separate the heated medium from the heat exchange medium. The water heater can't work normally or even the flow channel is frozen and damaged.

In addition, solar water heaters mainly use solar energy to produce hot water. At night or when the sun is not good, the hot water produced by solar water heaters may not meet the needs of production and life. Direct heating to meet the needs of production and life.

In order to achieve the above object, the technical solution provided by the utility model is as follows: provide an indirect heat exchange flat solar hot water system with an instant heating device, including a flat solar collector, a water storage tank, the water storage tank includes a The shell of the water tank, the liner installed in the shell of the water storage tank, the insulation layer filled between the shell of the water storage tank and the liner, the heat exchange device installed in the liner or on the outer wall of the liner, and the flat solar collector through The upper circulation pipe is connected to the inlet of the heat exchange device, the flat solar collector is connected to the outlet of the heat exchange device through the lower circulation pipe, and an instant heating device connected to the upper circulation pipe and the lower circulation pipe is also included. A temperature control valve is installed on the pipeline connecting the thermal heating device with the upper circulation pipe or the lower circulation pipe.

The beneficial effect of the indirect heat exchange flat solar hot water system with instant heating device described in the utility model is: by installing a heat exchange device in the inner tank or on the outer wall of the inner tank, the flat solar heat collector passes through the upper circulation pipe It is connected to the inlet of the heat exchange device, and the flat solar collector is connected to the outlet of the heat exchange device through the lower circulation pipe. The grid-shaped heat exchange flow channel circulates inside, so that the heated medium is separated from the heat exchange medium, preventing the formation of scale in the flow channel of the flat solar collector, and the heat exchange medium with antifreeze function can also be used to resist freezing, and the thermal efficiency is high. . It also includes an instant heating device connected to the upper circulation pipe and the lower circulation pipe. The pipe connecting the instant heating device with the upper circulation pipe or the lower circulation pipe is equipped with a temperature control valve. During operation, if the water temperature in the water storage tank cannot meet the user's needs, the temperature control valve will be opened and the instantaneous heating device will be activated to heat the heat exchange medium, thereby increasing the temperature of the medium and ensuring that the heated medium (water ) can meet the needs of users after exchanging heat with the heat exchange medium.
