Energy-saving control management system of network central air conditioner and method thereof

Abstract

The invention relates to an energy-saving control management system of a network central air conditioner and a method thereof. The control management system comprises a central control cabinet, a general network controller, an Internet network architecture and a network air conditioner, wherein the general network controller adopts a TCP / IP protocol as a network control protocol, sends operation parameters of the air conditioner to the central control cabinet by the Internet network architecture and receives and executes control instructions of the central control cabinet. The invention also comprises the energy-saving control management method which uses a system energy efficiency ratio COP<sys> as an air conditioner energy efficiency mark and adjusts the operation parameters of the air conditioner by calculating the dynamic system energy efficiency ratio so that the dynamic system energy efficiency ratio is constant maximum, and the central air-conditioning system can work in an energy-saving state to a maximum extent.
