Case Study on ECS-7000MT Cooling Tower Energy-Saving Controller and Central Air Conditioning Energy Management System

ECS-7000 Overview of Integrated Building Equipment Monitoring System:

The integrated building equipment monitoring system utilizes intelligent devices that integrate power distribution, control, energy efficiency, energy consumption measurement and analysis, safety alarms, and fieldbus communication to efficiently monitor and manage the building's HVAC/fresh air systems, ventilation, pumps, elevators, lighting, and other electromechanical equipment. The building equipment energy-saving controller should be installed within the power distribution cabinet of the controlled equipment. The controller should integrate relevant secondary circuit systems such as relays within the power distribution cabinet, employing sub-item energy consumption measurement, analysis, energy-saving control strategies, and fieldbus technology to reduce the operational energy consumption of building electromechanical equipment. 3. HVAC/Fresh Air Unit System

Monitor the actual electrical power, supply/return air temperature, CO2 concentration, etc., of the unit.

Automatically adjust the opening of cold/hot water valves and fresh/return air dampers to effectively control the system's fresh/return air ratio, total fresh/return air volume, cold/hot water flow, and fan efficiency under different seasons and operating conditions.
