The central air-conditioning system, also called centralized air-conditioning system, refers to an air-conditioning system that purifies, cools (or heats), humidifies (or dehumidifies), treats, conveys, and distributes air in a centralized or semi-centralized manner in the same building. It is mainly composed of air treatment equipment, air delivery equipment, air distribution equipment, cold (heat) source equipment and control parts.
According to the difference in the amount of refrigeration and the range of use, central air-conditioning is divided into two categories: central air-conditioning for industrial and commercial use and central air-conditioning for domestic use. Central air-conditioning for commercial and industrial use has a general cooling capacity of 50 kW or more. Central air-conditioning for household and similar purposes is a traditional one. A central air-conditioning product between a large central air conditioner and a room air conditioner with a cooling capacity of not more than 50kW. Industrial air-conditioning central air-conditioning is widely used in various industrial refrigeration locations, office buildings, shopping malls, rail transit, airports, hospitals and other types of large-scale construction .
Central air-conditioning has been mainly used in industrial professional places, commercial establishments and municipal places; in recent years, with the development of refrigeration technology, especially multi-line and small-scale water-cooled machines, traditional central air-conditioning work products have gradually entered the residential sector; based on Aiken air-conditioning Refrigeration network, HVAC information and industry online tripartite data.
Industry competition
After years of competition and development, the domestic central air-conditioning industry has taken the lead from foreign brands such as Europe and the United States, Japan and South Korea, and has formed a domestic, European and American brand, and the three major camps of Japan and South Korea. The domestic brand camp is based in Gree. The United States, Haier, Tiancai, the traditional five major European and American brands for Johnson Controls York, McQuay, Carrier, Trane, Dayton Bush, Japan and South Korea brands include Daikin, Hitachi (Tsingtao), Toshiba, Mitsubishi Electric and so on. Accumulation of precipitation in recent years, the trend of 'national advancement and retreat' has become increasingly prominent and obvious, the domestic brand camp market appeal and brand influence is increasing.
Central Air Conditioning Industry Status Analysis
Central air-conditioning applications are extensive, and can be used in office buildings, movie theaters, shopping malls, airports and other commercial public places, but also can be used in the family sector. According to the prospective industry research institute released "Central air-conditioning industry market demand forecast and investment strategic planning analysis report The data show that in 2017, the capacity of the central air-conditioning market could reach nearly one hundred billion yuan, an increase of more than 30% year-on-year. Among them, multi-line is the core category in the central air-conditioning market, accounting for 51.5% of the central air-conditioning market from approximately 45% in 2016. Occupy half of the country.

East China area is the most important central air-conditioning market in China
The central air-conditioning market demand is closely related to the level of regional economic development and residents' income levels. East China, North China, and South China are the regions with the most developed economy in China and the highest level of residents' income. They occupy the main share of the central air-conditioning market.
The trend of household consumption upgrades is obvious, and the demand for driving multiple inverters is continuously increasing.
From the cooling and heating effects, the central air-conditioning has more obvious effects on multi-connection, and the operation efficiency is high. From the aesthetic point of view, the central air-conditioning has many online structures, occupying less space, using only one outdoor unit, and the indoor The centralized management of the machine greatly reduces the energy consumption. In addition, the central air-conditioning multi-line service has a longer service life than the traditional air-conditioner. Therefore, under the trend of household consumption upgrade, central air-conditioning with more obvious advantages but relatively high prices Online demand continues to rise. Not only in first and second tier cities, but also in the three-and-four-tier rural market, where the trend of consumption upgrade is more pronounced, the penetration of variable-frequency and multi-line will continue to increase.
In general, whether it is from the central air-conditioning industry as a whole or just focusing on the domestic central air-conditioning sector, domestic brands represented by Gree and Midea have already occupied the commanding heights in the total amount, but when we subdivide into the product structure, the national brands are large. The features that are not too strong are evident, especially in the field of water machines that represent the state-of-the-art technology of central air-conditioning and the multi-industry areas that represent the future development direction of the industry. Therefore, the central air-conditioning industry needs to achieve similar domestic home- Work hard.
