What is home central air conditioning multi-connected?

Home central air conditioning concept originated in the United States, is relative to the traditional form of decentralized home air conditioning, it is also an important part of the commercial air conditioning, also known as household central air conditioning, unit-type adjustable central air conditioning. Its working principle is similar to the central air conditioning, but also by a host through the air ducts to send air or hot and cold water to drive a number of end of the way to control the temperature of different rooms, in order to achieve the purpose of indoor air conditioning for the purpose of air conditioning. It combines the advantages of large-scale central air conditioning and home air conditioning, and can simultaneously meet the needs of a variety of household types of more than 70 to 600m2 multiple rooms. According to its working principle can be divided into two kinds: one is by the large central air conditioning system evolved from the air conditioning system, such as small air-cooled chiller, small air duct unit, etc.; the other is by the split wall air conditioning equipment evolved from the air conditioning system, such as a tow four, a tow more, and so on.

Home central air conditioning is divided into two kinds of wind system and water system. Wind system consists of an outdoor machine, indoor host, air supply piping and various rooms of the air outlet and control valve, etc., the use of duct air supply, with a host can control a number of different rooms, and can be introduced into the new air, can effectively improve the quality of indoor air, prevent the occurrence of air-conditioning disease; water system consists of an outdoor machine, water piping, circulating pumps and various indoor end (such as fans, coils, etc.) consists of cooling water, cooling water and heat exchanger, heat exchange, cooling water and heat exchanger, cooling water and heat exchanger, cooling water and heat exchanger, air-conditioning system. Exchange heat with the heat exchanger, so as to achieve the purpose of regulating the indoor temperature.

At present, the home user type central air conditioning is mainly divided into two genres: one is the water-cooled genre represented by the United States, such as Keli, York, Trane, McWhirr, Tsinghua Tongfang, etc.; the other is the Freon or lithium bromide genre represented by Japan, such as Hitachi, Daikin, Sanyo, Qingdao Haier, and so on.
