Central air-conditioning system mainly includes two parts: hot and cold source host part and end equipment part, central air-conditioning self-control system, need to be equipped with automatic control system.

Analysis of the principle of energy conservation

Central air-conditioning system operating energy consumption is the most important energy consumption link in most public buildings, building energy consumption in the central air-conditioning system energy consumption of about 50%-70%, the recent national energy-saving targets and people's awareness of energy conservation gradually enhanced, reduce energy consumption enterprises not only increase disprofitability, but also advocate the national policy of energy conservation and emission reduction.
