although domestic market of central air conditioners is affected by economic environment and the fixtures market is in a downturn in recent years, great potential has been found in non coal heating, healthcare, home improvement, rail transit, industrial waste heat utilization, and special air conditioners for base stations, nuclear power plants, data centers and more. the central air conditioner companies need to think carefully about seeking more market space in the increasingly fierce competition. however, the general considerations are how to improve product efficiency and lower costs. as a result, some of the companies found breakthroughs in energy saving retrofits.
some earlier installations of central air conditioners in china, especially for high-end hotels, metros built in the early years and public buildings, are now facing retrofit issues due to high energy consumption, backward technology and product aging and have bigger demands for magnetic levitation oil-free chillers with high energy efficiency and add-on flexibility. multistack modular oil-free chillers feature energy saving, higher refrigeration efficiency than traditional oil-lubricated chillers, never-drop energy efficiency, low maintenance and operating costs. typical example is the central ac retrofit project for the supercomputer room of national oceanographic center, qingdao. multistack helps save maintenance costs for about ￥50,000 yuan annually and other annual expenses for ￥1.92 million yuan. after the debut of modular oil-free chillers, multistack adopted a different marketing strategy of “applying before promoting”. in the “applying” stage, the modular oil-free chillers showed remarkable energy-saving performance and were highly appreciated by the user.
policy of “non coal heating” brings energy saving brands
nowadays, china’s air environment quality is challenged by murky haze, especially in beijing, tianjin and hebei regions. warnings of “heavy air pollution” have been issued again and again. in order to reduce fuel pollution and improve air quality, many cities of northern china carried out the policy of “non coal heating”, which presented huge business opportunities for central air conditioning companies. multistack won bids for “non coal heating” projects and became one of the enterprises supplying central air conditioners to beijing, tianjin and shanxi. the “non coal heating” policy was issued in 21 cities and provinces in china in 2017 which will expand the market significantly.
