Central air-conditioning by a host through the air duct or hot and cold water pipes had received a number of ways to control the end of the room in order to achieve different indoor air-conditioned air-conditioning purposes. Air supply duct means used by a host to control a variety of room and fresh air can be introduced to effectively improve indoor air quality, air-conditioning to prevent the occurrence of disease. Residential central air-conditioning and is independent of a small air-conditioning system, is to focus on the form of air conditioning load of the system, the cold heat transfer medium by means of some to the air-conditioned rooms, to meet the requirements of a comfortable living.

     Residential central air-conditioning allows the emergence of a more beautiful living room, central air conditioning in today's market has become a popular product, especially in the real estate market. Experts in the industry, residential central air-conditioning of this benefit, "fat" the market is relatively high for some time in the future will become the vital importance of the manufacturers. They think that, in addition to the necessary marketing strategy, quality of products under its own great efforts, and continue to meet people's demand for progress in the quality of life is fundamental to all business development.

     Residential central air-conditioning was good

     As in recent years to improve the living conditions of people, along with environmental protection and enhancement of health consciousness, people started to take their own lives and the working environment air quality, and residential central air-conditioning due to the installation of beautiful, and has a number of rooms at the same time to the cooling heating function, the beginning by a number of high-income families of all ages.

     Not only that, but the general air-conditioning in the home of the now shrinking profit, residential central air-conditioning was as high as the profits of about 20%. Therefore, adding residential central air-conditioning market competition, in addition to Tsinghua Tongfang, York and other large central air-conditioning manufacturing giant, there are a number of domestic air-conditioning "players", such as Haier, Gree, such as the United States.

     At the same time, also known as professionals, by income level and housing restrictions and other factors, at least for now, residential central air-conditioning demand is still limited. Such as a 100 square meters of三室一厅as an example, the installation of 3-4 tuyere, the price at 1.8 million to between 20,000 yuan. At present the market price of the installation of three sets of ordinary air-conditioning, only about half the cost.

     To be cost-effective products to improve

     Due to the vast majority of residential central air-conditioning means the use of air-cooled, the unit coefficient of performance (COP) has always been low. Therefore, to improve host performance, increase the coefficient of performance units, first of all, to improve the compressor performance, the use of high-performance inverter compressor, the compressor to improve the accuracy of processing and assembly of the compressor to optimize the structure design; Second to increase heat exchanger heat transfer efficiency, the use of new materials, new processes, optimizing the heat exchanger structure; the final to improve the fan, water pump structure. At present, the unit should improve the coefficient of performance evaluation methods, the use of a condition only factor to evaluate the performance of unit energy consumption is far from enough, many experts have suggested that the use of seasonal cooling (heat) coefficient to evaluate the performance of generating units energy consumption. At present, the evaluation software in this regard, the use of the results can be well in line with reality.

     Residential central air-conditioning performance of the host not only performance, but also the installation of officers of the level and quality installation. Even the best performance of the host, if the poor quality of system installation, the host will not be able to give full play to its efficiency, so that air conditioning performance has been greatly affected.

     Residential central air-conditioning compressor is mainly affected by the price, heat exchanger, fans and valves affected. Since the majority of residential central air-conditioning compressor are imported from abroad, accounting for the price of the unit cost of 1 / 4 to 1 / 3, plus a number of key valves also need to import, therefore, residential central air-conditioning prices also high, this is the impact of its rapid access to the family of one of the main factors. As China's scientific and technological progress, more and more parts will be replaced by domestically produced components, the future of residential central air-conditioning will be increasingly cost-effective.

     In addition, environmental protection is an eternal topic of human beings. For residential central air-conditioning, it contains a lower unit noise, lower energy consumption, the use of sound, recyclable, renewable cooling agent, this need has been actively exploring manufacturers. Huge market demand for space, determine the residential central air-conditioning is very optimistic about future prospects, the market capacity of the factories and businesses to make more optimistic.
