The near and far room temperature sequence and energy consumption caused by hydraulic imbalance in air conditioning system

For public buildings air-conditioning system downtime in the evening, every morning as soon as possible to the maximum load to return to a comfortable room temperature. This can be done quickly with a hydraulically balanced system. If the cooling unit is started 30 minutes earlier than normal, the daily energy consumption is increased by 6%. If the unit starts up two hours early, imagine the additional energy consumption. After starting the night every morning during startup, most control valves are fully open in the variable flow system for regulation. If the system is unbalanced, near-end users will have overcurrent and under-current at the system's proportional loop. Adverse Loop To wait until favorable loop temperature reaches the set temperature is, in order to get the design flow. For all loops, including an advantageous loop, this will extend the time to reach the design temperature, produce a near-to-user room temperature timing, a long timing, and the higher the cost in terms of energy savings. The serious timing makes it almost impossible for the central control system to be completed in actual operation.
