<br> This chapter includes air conditioning works, air conditioning systems, common air-conditioning equipment, air conditioning, refrigeration and air conditioning systems maintenance management five parts. ① air conditioning works including air composition and State parameters, air-conditioning of tasks, .the role of air conditioning and air conditioning system's basic structure. The basic structure of the air conditioning system, cooling system and air treatment and energy transmission distribution systems and automatic control systems, four subsystems. ② air conditioning system for the classification of a lot of .ways, according to the device settings can be divided into a centralized, detached and semi-centralized wait three types; press the air source is broken down into direct current, closed and recirculation systems, etc. Common centralized and centralized air conditioning system, a .centralized single duct air conditioning system, centralized double duct system and air blower plate Tube type air conditioning system. ③ common air conditioning equipment washers, surface heat exchangers, air humidification or reducing wet processing equipment, air purification equipment and air delivery and distribution equipment. .④ refrigeration system consists of refrigeration equipment, frozen water pipes and cooling water pipes, three subsystems. Refrigeration unit is at the core of the refrigeration system, common refrigeration modes have steam compression, absorption, etc. ⑤ air-conditioning system maintenance management includes air .conditioning system management, maintenance of air conditioning system, air conditioning and refrigeration equipment maintenance room maintenance and management. Refrigeration room is the entire building air-conditioning system's core, is the layout of the refrigerating system equipment specialized room. Good room management is the normal .operation of the air-conditioning system, the key is also important for property and equipment management. <br>.
