Влияние рабочего тела на коэффициент преобразования теплового насоса.

Various refrigerants used in heat pumps are compared according to their effectiveness. Formula for approximate definition of COP is offered for various refrigerants. It is exposed that values of COP for refrigerants under consideration differ a little one from the other and are equal 4,6...5,2 at Δt = 25...35 °C.
