为了得到经济高效的具有两种工作容量的空调系统,人们已经试过了各种方法。比如:使用两个压缩机,使用双速压缩机,使用速度可调的压缩机。然而,这些方法通常过于复杂和昂贵。为了解决这个问题,弗吉尼亚州的Bristol压缩机制造厂改造了原有的压缩机设计,他们更换了一个关键的部件,从而创造了一种单压缩机提供两种容量的方案,而且该方案只有其它方案成本的几分之一。这项技术被称之为TS(取 Various methods have been tried to get a cost-effective air-conditioning system with two working capacities. For example: the use of two compressors, the use of two-speed compressors, the use of adjustable speed compressors. However, these methods are often too complicated and expensive. To solve this problem, the Bristol compressor manufacturing facility in Virginia modified the original compressor design and replaced a key component, creating a single-compressor solution that offers both capacities, with only the other A fraction of the cost of the program. This technique is called TS (take
