Central air conditioner-based medium water temperature difference power generation device

Abstract

The invention relates to the technical field of central air conditioners, and discloses a central air conditioner based medium water temperature difference power generation device which comprises a wall. A water tank is arranged at the outer side of the wall, an inner tank is arranged in the water tank, and a heat preservation layer is arranged between the water tank and the inner tank; and multiple sets of temperature difference power generation pieces are distributed on the outer surface of the water tank at equal intervals. A fan coil water return pipe is installed at the inner side of thewall, one end of the fan coil water return pipe penetrates through the wall and the water tank to be communicated with one end of the inner tank, a polarity converter is installed at the other side, close to the water tank, of the outer side face of the wall, and a storage battery is installed at one end of the polarity converter. The temperature difference between the water temperature in the fancoil water return pipe and the outdoor environment temperature is reasonably utilized through the medium water temperature difference power generation device, power generation is conducted through the temperature difference between the water temperature in the fan coil water return pipe and the outdoor environment temperature, a large amount of electric energy can be continuously generated and stored for living needs, and the device does not need to consume electric energy, greatly relieves power supply pressure and is higher in practicability, and stronger in social effect.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a power generation device based on the temperature difference between medium and water of central air-conditioning. Background technique [0002] Now office buildings and hotels have installed central air conditioners. In summer and winter, the central air conditioners will be turned on. In summer, the temperature of the water in the return water pipe of the media water fan coil is 12-15 degrees, which is lower than the outdoor ambient temperature. There is a large temperature difference between them. In winter, the temperature of the water in the return water pipe of the fan coil unit is 50-70 degrees higher than the outdoor ambient temperature. There is also a large temperature difference between the two, and the air conditioners in office buildings and hotels are long The operation of the whole circulating water system keeps circulating, so that there is a con...

Problems solved by technology

[0003] In view of the above-mentioned how to make reasonable use of the temperature difference between the water in the return pipe of the medium water fan coil unit and the outdoor environment, or use the temperature difference device to generate electricity, a large amount of electric energy can be continuously generated and stored for daily needs, and this device does not need Consumption of electric energy greatly alleviates the problem of power supply pressure. There is no effective technical solution in the prior art. Therefore, those skilled in the art provide a power generation device based on central air-conditioning media water temperature difference to solve the above-mentioned background technology. question
