Recently, the high-efficiency, energy-saving, outdoor unitless air conditioner with the patented technology of “Water Source Heat Pump Household Air Conditioning” has been jointly developed by Hangzhou Chunqiu Air Conditioning Co., Ltd. and Sansuo Technology Co., Ltd. The successful research of this technology has enabled the split air conditioner to get rid of the "outdoor machine", and has made significant progress in energy saving and environmental protection.

This type of outdoor unit air conditioner is designed to maintain the existing air conditioning performance, and the transformation mode is reformed and innovated. The surface air, ground water or tap water is used to replace the outdoor air that the existing air conditioner relies on for energy conversion.


The energy conversion process is completed by the water circulation in a closed state, so that the main part of the air conditioner operation and conversion (commonly known as the outdoor unit) can be installed indoors, which is beneficial to safety and maintenance, and beautifies the appearance of the building. Moreover, the air-conditioning technology has achieved a breakthrough in energy-saving efficiency, exceeding the estimate of 40% energy saving rate of the technology in patent application.
