Air conditioning refers to the process of conditioning and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in buildings/structures by artificial means. It generally includes cold/heat source equipment, cold/hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes water pump, fan and pipeline system. The terminal device is responsible for the specific treatment of air by using the cold and heat transferred, so that the air parameters of the target environment can meet the requirements.
