At this conference, YAIR Central air conditioning released a number of products. It covers more than ten kinds of central air conditioning product series of ultra-low temperature, low temperature and standard unit series.

The ultra-low temperature VWV air source heat pump heating dual supply unit on display at this conference can realize the heating needs in the ultra-low temperature environment and provide integrated heating and cooling solutions for families. Through the world's first "two-stage vortex compression technology", it achieves ultra-low temperature environment heating of -45 ° C, breaking the industry exclusion zone. This technology creatively developed the Yangtze "high efficiency ultra-low temperature strong heat air conditioning" unit. So that the unit can be reliable heating operation at -45 ℃, ultra-low temperature environment heating ability is strong, is the ideal product for cold, extremely cold area heating.

"Two-stage vortex compression technology" is the industry's first patented innovation technology, and it is also the only single heat pump system that can achieve heating function in extremely cold areas (below -40 degrees ring temperature). It is of great significance to improve the energy structure in extremely cold areas and further improve energy efficiency! This is also an outstanding contribution made by China as a responsible major country in the context of the "double carbon goal" proposed by the United Nations.
