The invention discloses a remote energy-saving control method and device for a central air conditioner fan coil, and belongs to the technical field of building energy conservation and intelligent control. Aiming at the problems that the prior non-intelligent temperature control panel cannot be controlled remotely, so that energy is wasted, the traditional transformation scheme has high cost and complex construction, the invention creatively discovers and utilizes the inherent characteristic that the non-intelligent temperature control panel is configured to automatically close the water valve in an initialized state after power failure is restarted. According to the method, a remote energy-saving control instruction is received, a module connected in series in a panel power supply loop is controlled to execute power-off-delay-power-on operation, and the panel is triggered to restart, so that the reliable closing of a fan coil water valve is indirectly realized. The corresponding device comprises a communication unit, a power supply control unit and a processing unit. The invention realizes low-cost non-invasive energy-saving transformation of the stock non-intelligent system, and has remarkable economic benefit and practical value.

Description

Remote energy-saving control method and device for central air conditioner fan coil Technical Field The invention belongs to the technical field of building energy conservation and intelligent control, and particularly relates to a remote energy-saving control method and device for a central air conditioner fan coil. Background Along with the increasingly urgent need of energy conservation and emission reduction, the fine energy-saving control of a central air conditioning system, particularly a fan coil unit widely applied to offices, hotels and other scenes, has become an important link of intelligent management of buildings. Traditional fan coils are usually controlled locally by an intelligent temperature control panel, and the panel has single function and cannot receive remote instructions without network communication capability. When people leave the area, the air conditioner is always continuously operated because the air conditioner cannot be closed remotely, so that a large amount of energy is consumed. Currently, the main scheme of energy-saving transformation of such stock equipment is to replace the stock equipment with an intelligent temperature control panel with a communication function. However, this scheme is costly, needs to rewire and construct the wall, implements the degree of difficulty in the building that has finished with the fitment, the cycle is long, and abandons original equipment and cause the wasting of resources. In order to reduce the transformation difficulty, some schemes for realizing remote switch by controlling the on-off of a fan coil power supply loop also appear in the industry. However, these solutions generally only control the start and stop of the blower, but cannot close the critical component water valve that controls the flow of hot and cold water. If the fan is stopped and the water valve is not closed, the cold and hot media in the coil pipe still exchange heat circularly, and the real energy saving cannot be realized. The other thinking is to add an independent electric valve in the waterway, but the existing pipeline is required to be cut and reformed, the construction is complex, the cost is also not very good, and the risk of water leakage exists. Therefore, on the premise of not changing terminal equipment on a large scale and not damaging the original decoration and waterway, the method for effectively and remotely switching off the water valve of the non-intelligent fan coil becomes a long-standing technical problem which is not solved effectively. Accordingly, the present invention is directed to a method and apparatus for remote energy saving control of a central air conditioning fan coil that at least partially addresses the above-mentioned problems.
