Cristiano Paoletti - patent application - Heat Pump

My patent application solves the problem of inefficiencies due to inevitable defrosts of air source heat pump (ASHP).

1. My Patent Application Ing. Cristiano Paoletti already published in Europe and United States and Japan

2. solves the problem of inefficiencies due to inevitable defrosts of air source heat pump OK, but what about these inefficiencies ? …and, which is more, what is an heat pump? My Patent Application

3. 1 kW 2 kW gratuit 3 kW

4. What we want to have ___________________ = Coefficient of Performance Heat Pump Efficiency What we have to spend COP = ____ 3 kW 1 kW = 3

5. second law of thermodynamics according to Carnot’s formulation COP Tcold ________ Thot- Tcold BUT there is water vapor in the air….

6. We need defrosting cycles !

7. -18% Due to the defrosting cycles …… inefficiencies occur !

8. -28%

9. -20%

10. Someone proposed this … In defrosting Evaporating Evaporating …and cycling whitout STOP!

11. GREAT!!!

12. GREAT!!! In defrosting Electric Power

13. FANTASTIC!!! In defrosting

14. In defrosting How to connect ? But………. (in order to switch between the three evaporators )

15. In defrosting But………. Very bad !

16. This is my invention !

17. -18% WHY? -6%

18. In defrosting Evaporating Evaporating JUST DEFROSTED PARTIALLY FROSTED Optimal Evap Pressure > Optimal Evap Pressure SOLUTION = EJECTOR!

19. How to connect ? Ejector ! OK,BUT….

20. Ejector ! OK,BUT…. How to connect ?

21. Instead ! What’s this ?

22. This is an automatic valve ( invented by me) which I have named C.R.I. valve C lose on R ise of I nlet pressure valve

23. -6% Everything recovered ! With my C.R.I. valve

24. Everything recovered ! BUT… more is possible ? YES… with Expander !

25. group fully automatic – NO control at all !
