Description

Air conditioner waste heat recovery utilizes device Technical Field The utility model relates to the technical field of air conditioner waste heat recovery, in particular to an air conditioner waste heat recovery and utilization device. Background With the increasing demand of energy and the deep penetration of the energy conservation and emission reduction concepts, the air conditioner waste heat recycling technology gradually becomes a research hot spot. In the existing air conditioner waste heat recovery system, a heat conduction pipe is generally adopted to transfer waste heat generated by air conditioner operation to a medium in a water tank, so that heat recovery is realized. However, the system has two general problems that firstly, the medium in the water tank is in a relatively static state, so that the heat exchange efficiency between the medium and the heat conduction pipe is low, and the waste heat cannot be fully recovered, secondly, the heat conduction pipe is easy to adhere to dirt such as scale, dust and the like on the surface to form thermal resistance in the long-term use process, so that the heat exchange efficiency is further reduced, the problem that the heat conduction pipe is time-consuming and labor-consuming to clean manually, and the problem that the cleaning is not thorough exists is solved, and in addition, the existing waste heat recovery device cleaning mechanism and the heat exchange strengthening mechanism often need independent power sources, so that the equipment structure is complex and the energy consumption is high.
