Calorific effect in evaporator from mine compression refrigerator with different refrigerants Authors: K. Filek, B. Nowak
This work refers to use the pre – ecological refrigerants (R404A, R407C and R507) in mine compression
refrigerator. The work includes the results of air measurements and calculation. The measurements were
made on a test stand for 135 variants, which took into account various temperature, moisture and velocity
of air fl ow value through evaporator. The calculations were made by using numerical equation, which
were a mathematical model of cooling of air by using the compression refrigerator. All results are shown
in a table. This table is contained 48 cases, which are the most interesting in practical point of view. In
the other table are set up the differences in results of calculations and measurements.
