Cold and hot water control method for cold and heat source machine, and air conditioning system using it

摘要: PROBLEM TO BE SOLVED: To provide a cold and hot water control method for heat source machine, an air conditioning system using it capable of carrying out further energy saving by simple structure reducing flow rate pump while suppressing increase throttling resistance valve to secondary side facility such as conditioner, controlling even supply temperature in response opening the facility, electric power consumption machine. SOLUTION: The is provided with pump, plurality facilities parallel each other, valve. detected, pressure reduced inverter that largest becomes substantially fully opened. If still does not become opened, machine raised when supplying water, lowered water. COPYRIGHT: (C)2008,JPO&INPIT
