The problem is that an outdated inefficient Rankine Refrigerant Heat controls 99% of the market and in extreme climate temperatures (High Delta Ts) the Rankine COP efficiencies are 0-1 in the example of - or + 10-20C , virtually useless and use excess Kwh. The HVAC OEMs are about the slowest good ole boys to adapt or innovate. Our co, Sencera (sincere.com) is mfg the 1st Stirling Heat Pump that replaces Rankine Refrig Heat Pumps @same and delivers 30% HIGHER COP efficiency over Rankine Heat Pumps and is performs even better in extreme cold/hot climates. Trust and used by NASA Stirling was previously known as super expensive and used in the RPS systems in the Space shuttles. We reconfigured Stirling to be low cost ($600 mfg cost 3 Tom/10Kwh Units) with a Patented all Rotary design and utilize Helium or Nitrogen(NON toxic and NON flammable) with working prototypes with independent lab verified COP efficiencies HIGHER than Rankine. In 2024 you'll see the comm'l entry of our 1st Home Units then we scale to EVs and Comm'l Cold Chain apps. Since 100% of every Rankine Heat Pump leaks in all Homes, Schools, Hospitals and Businesses and depends on Refrigerants, the lazy HVC market's new spin is "sustainable" Refrigerants, such B.S, they contain harmful CFC/HFCs or in Europe you have R-290, a Propane derivative, try lighting a match next to it and see what happens:). The Industry is so old and apathetic it's going to see a refreshing disruptive change maker in Stirling as an end user option that can serve Colder/otter climates and significantly reduce Kwh/Utility Bills.
