REAL-A Central Air Conditioning Energy-saving Cloud Control Management System

1、System Equipment Control and Management

Due to the characteristics of multi-parameter, nonlinearity, and fluctuating cooling and heating loads in central air conditioning systems, it is easy to cause the system operating conditions to deviate from the efficient operating state, resulting in reduced thermal conversion efficiency of the chiller units. Under the condition of ensuring comfort, in order to improve the energy efficiency of the central air conditioning system, comprehensive energy efficiency tracking control and management of various components such as chiller units and water circulation systems must be implemented.

2、Chiller Units

Based on the collected supply and return water temperatures, pressure, flow rates of the chilled and cooling water circulation systems, and ambient temperature and humidity, the central air conditioning intelligent controller calculates the actual system load and dynamically adjusts the number of operating chiller units and temperature settings. The control modes of chiller units can be divided into two situations.

3、Hot Water Circulation

When ambient temperature, humidity, system process parameters, and the heat load of the air conditioning terminals change, the process parameters of the water circulation system also change accordingly. The central air conditioning intelligent controller optimizes the efficiency of the chiller units based on the cooling load value, provides control strategies, dynamically adjusts the chilled water flow rate through the chilled water pump energy efficiency controller, dynamically adjusts the cooling water flow rate through the cooling water pump energy efficiency controller, dynamically adjusts the hot water flow rate through the hot water pump energy efficiency controller, and adjusts the operating frequency of the cooling tower fans through the cooling tower fan energy efficiency controller to meet the user's heat demand and ensure that the COP of the chiller units remains in an efficient conversion state.

4、Energy Management

On the management computer, centralized control and energy efficiency management of system equipment such as chiller units and related electric regulating valves in the water circulation system are achieved. Through the intelligent metering unit, electricity consumption statistics of the air conditioning system are transmitted via the energy bus to the management computer or other energy statistical management systems, enabling the statistical management of system operating parameters and energy statistical reports.
