Recently, due to its high efficiency advantage, the VRF system business has been rapidly growing since 2004. Considering that the replacement cycle of air conditioners is usually about 10 years, the time of replacement of the system air conditioners introduced in the early days has arrived, and interest in the cost and process of replacement is increasing due to the discontinuation and aging of the components of the existing systems. Therefore, we propose a site customizable replacement solution that can re-use the existing pipes while replacing the indoor and/or outdoor units in the residential market. In addition, we introduce residential replacement case studies that present system air conditioner energy efficiency improvements and various cost reductions.
