If the hotel hot water is constant pressure, which is better, open or closed? What is the difference? Will the general company help to consider these comprehensive problems?
For the open system, a certain volume of return water tank should be considered to prevent the pump from being cut off. If the system pipeline is long, check whether the return water tank will be sucked up according to the flow time in the pipeline, and pay attention to the installation height of the water pump to prevent cavitation. Open systems are rarely used in air conditioning systems, especially in high-rise hotels. However, in recent years, due to the development of air conditioning technology and the need of energy saving, many foreign projects adopt cold storage pool air conditioning, and the corresponding water pipe system needs to adopt open system.
In a closed system, the water pipe at the end of the system is not connected with the atmosphere. Because the whole system in close system is full of water, the pump head only needs to overcome the circulating resistance, and does not need to overcome the static pressure of the water column, so it saves electricity. Considering the expansion characteristics of water, close system usually needs an expansion tank. In the design of chilled water piping system, when both systems can be used, close system should generally be adopted. Generally, there will be such service, but the problem about equipment is very important, and it should be in place after sale. I recommend Finney's central hot water unit to you, which can be trusted for 3 years after sale.
