Belyayev AB - At low ambient temperatures, the heating capacity and coefficient of performance of a single stage vapour compression heat pump cycle is significantly getting reduced. A two-stage cascade heat pump cycle operating with two different refrigerants provides a sustainable solution to lift the condenser temperature above 70 ℃. Calculation of thermal performance for various refrigerants pairs has been carried out by using Engineering Equation Solver software. The following refrigerants pairs R410A/R290, R410A/R1234yf, R410A/R134a, R410A/R407C, R32/R290, R32/R1234yf, R32/R134a, R32/R407C, R404A/R290, R404A/R1234yf, R404A/R134a, R404A/R407C, R744/R290, R744/R1234yf, R744/R134a, R744/R407C for low and high-temperature cycles have been tested numerically. R32/R134a and R410A/R134a shows the highest vapour compression cycle COP 1.98 from -30 ℃ ambient air temperature and +60 ℃ heating circuit temperature range, but they will be eventually suppressed in near future by Paris Agreement. As an environmentally friendly alternative to the previous pairs in the cascade cycle, R32/R290 and R744/R290 working fluids combinations are proposed.
