How to design the hotel air conditioning hot water system?

1, depending on the distance between the hot water source and the water point. If the distance is too far, a lot of cold water must be released. This problem is particularly prominent when the central hot water system supplies water. If the water supply is decentralized, if there is no toilet and no water heater, there will be no such problem.

2. In the description, a hot water pipe is divided into floors, which should be a centralized hot water supply system (so-called central hot water system). This water supply mode should be used as a hot water reflux device, that is, a hot water circulation system. The specific method is to connect a return pipe from the hot water supply end to the bottom of the hot water supply source, and circulate it through the water pump in the middle, pumping the cold water accumulated in the main pipeline to the hot water source for reheating, so as to ensure that hot water can still be used after the water and electricity turn on the tap (because only the accumulated water in the main pipeline is discharged, there is still a small amount of accumulated water in the branch pipe when it is used). The circulating pump can be controlled by temperature, time, manual or water flow switch.
