Full Description
Reports a drop-in system performance comparison of refrigerants R22 and R407C. The test conditions include standard rating condition, overload condition and low-temperature condition. Finds that the cooling capacity of R407C is about 3% lower than that of the R22 system, and the coefficient of performance for the R407C system is 4% lower than that of the R22 system. The drop-in test results show that the condensing pressure for R407C is 200 to 300kPa higher than that of R22.
