How can we use R-729 (air) into an AC system that produces comfortable air like an AC system that uses halogen refrigerant? Efforts to thoroughly address the challenges of climate change in the refrigeration sector. If air as a refrigerant is treated in the engine cooling system according to the vapor compression cycle, it will be very dangerous because the air refrigerant (R-729) contains oxygen gas. Based on the fire triangle rule, this will result in the problem of a fire incident. So it needs to be designed not by following the vapor compression cycle. The knowledge of how R-729 (air) as a refrigerant has been liquefied, is the scientific basis that can be developed into an AC system using R-729. In the air liquefaction process (R-729) high pressure is required and is carried out at several levels, then it is "expanded" using a special compressor where the driving motor is outside (open compressor type) To make R-729 can be used to produce a comfortable temperature, there is no need for high pressure. Because we don't need the R-729 liquid phase to be processed. Just reach a temperature of up to 18C. How to produce this system!!, of course the next article will answer that. #R729
