HVAC COOLING WATER CONTROL SYSTEM AND CONTROL METHOD FOR HIGH-RISE BUILDING

摘要

The present invention relates to an air-conditioning water control method and an air-conditioning water control system of a high-rise building, comprising: a primary circulation pump system composed of a plurality of heat source devices and a circulation pump and supplying a circulated flow rate; A secondary circulation pump system configured to receive and output a flow rate of the heat source supply system, and include a plurality of circulation pumps, a pump control valve, and a plurality of pressure escape and retention valves connected in parallel to the circulation pump and the pump control valve; A circulation line connected to the output side of the secondary circulation pump system and purified to low, middle, and high-rise subsidiary systems, respectively; Not only is the system suitable for the high-rise building of unit buildings that do not use the local heat source, it is composed of a guinea circulation system consisting of a decompression and maintenance valve that returns the flow rate of the circulation line to a constant pressure after decompression, and saves energy and uses space. It is possible to operate stably by keeping constant the internal pressure of air conditioning piping water control system.
