What is central air conditioning?

The concept of home central air conditioning originated in the United States. Compared with the traditional decentralized home air conditioning form, it is also an important component of commercial air conditioning. It is also called household central air conditioning and unitized adjustable central air conditioning.

Its working principle is similar to that of central air conditioning. It also uses a host computer to drive multiple terminals through air ducts or hot and cold water sources to control the temperature of different rooms to achieve indoor air conditioning.

It combines the advantages of large-scale central air conditioners and ordinary household air conditioners, and can simultaneously meet the needs of multiple rooms of various house types ranging from 70 to 600 m2.

According to its working principle, it can be divided into two types: one is the air conditioning system evolved from the large central air conditioning system, such as small air-cooled chiller unit, small air duct unit, etc.; the other is the air conditioning system evolved from the split wall-mounted air conditioning equipment.

Various air conditioning systems are available, such as one-to-four, one-to-multiple, and so on.

Home central air conditioners are divided into two types: wind system and water system.

The air system consists of outdoor units, indoor hosts, air supply ducts, air outlets and regulating valves in each room. It adopts the air duct air supply method. One host can control multiple different rooms and introduce new air, which can effectively improve

The quality of indoor air prevents the occurrence of air-conditioning diseases; the water system consists of outdoor units, water pipes, circulating water pumps and various indoor terminals (such as fans, coils, etc.). It exchanges heat with cooling water and heat exchangers to achieve regulation.

indoor temperature purposes.

At present, household central air conditioners are mainly divided into two schools: one is the water-cooled school represented by the United States, such as Kaili, York, Trane, McQuay, Tsinghua Tongfang, etc.; the other is Freon or Freon represented by Japan.

LiBr school, such as Hitachi, Daikin, Sanyo, Qingdao Haier, etc.
