3中國產業信息網發布的《2015-2020年中國中央空調市場專項調研與投資方向研究報告》指出：隨著綠色經濟與低碳經濟時代的發展，空調行業的技術開發也緊隨潮流，呈現出鮮明的新的發展趨勢：更高的運行節能性與更低的生產消耗，更完善的舒適健康性，更人性化的使用便利性和智能化。空調技術開發主要圍繞以下幾個主題：
? ? 變頻空調技術，提高節能制冷效率，環境保護，提高舒適性和空氣品質，智能化網絡控制。
① 變頻空調技術② 提高節能制冷效率③ 環境保護和安全性④ 靜音化⑤ 高舒適性和室內空氣品質⑥ 智能化網絡控制
用戶使用情況:隨著社會的發展，城鄉結構以及政策的調整，政府對于農村問題的關注，近年來農村整體生活水平有所提高，食品類家電類紛紛得到
普及提升，空調作為區分電視等普通家電的高檔家電，也得到一定的普及，放眼望去，大多數房屋外都掛有空調壓縮機。但使用情況不大樂觀。

The product cycle is an economic theory that was developed by Raymond Vernon in response to the failure of the Heckscher-Ohlin model to explain the observed pattern of international trade. The theory suggests that early in a product's life-cycle all the parts and labor associated with that product come from the area where it was invented. After the product becomes adopted and used in the world markets, production gradually moves away from the point of origin. In some situations, the product becomes an item that is imported by its original country of invention.[1] A commonly used example of this is the invention, growth and production of the personal computer with respect to the United States.
