伴随着中国经济的高速发展,小型中央空调市场在中国越来越兴盛。而在其中,商用场所对这一产品的需求更是处于高速增长之中。众所周知,在目前的市场中,主要有三种类型的产品:风管道式系统、水管道式系统以及变冷媒流量系统。而变频多联技术作为变冷媒流量技术中的一种,在市场中的运用和实践已经具有相当长的时间和经验了。采用该技术生产的变频多联式空调系统(简称变频多联机),具有安装简便、不占用室内空间、温度自由设定、可实现变频控制以及独立换新风等优点。同时据有关业内人士介绍,变频多联式空调系统通过变频或变容量调节,与其他技术类型的系统相比,在节能上有着比较明显的优势;而与传统的中央空调系统相比,则省去了主机房、冷却塔、水输配系统等等,逐渐成为商用空调的主要发展趋势,特别是在500-5000m~2的舒适性空调建筑内,越来越多地受到了业主的欢迎。2003年1月8日,海信集团与日立空调共同投资2亿元,成立了海信日立空调系统有限公司,其产品就紧紧锁定在变频多联式空调系
With the rapid development of China’s economy, the small central air conditioning market is booming in China. Among them, the demand for commercial products in this product is in rapid growth. As we all know, in the current market, there are three main types of products: wind pipe system, water pipe system and variable refrigerant flow system. The variable frequency multi-joint technology as a variable refrigerant flow technology in the market in the use and practice has been quite a long time and experience. The frequency conversion multi-type air conditioner system (referred to as frequency conversion multi-line machine) produced by this technology has the advantages of easy installation, no indoor space occupation, temperature free setting, frequency conversion control and independent replacement of fresh air. At the same time, according to relevant industry insiders, frequency conversion multi-linked air-conditioning system through frequency conversion or variable capacity regulation, compared with other technology types of systems, energy saving has a more obvious advantages; and compared with the traditional central air conditioning system, the province To the main engine room, cooling towers, water distribution system, etc., has gradually become the main development trend of commercial air conditioners, especially in the 500-5000m ~ 2 comfort air conditioning building, more and more by the owners welcome. January 8, 2003, Hisense Group and Hitachi Air Conditioning jointly invested 200 million yuan, the establishment of the Hisense Hitachi Air Conditioning Systems Co., Ltd., its products are tightly locked in the frequency conversion multi-linked air-conditioning system
