    Zmiana parametrów termodynamicznych powietrza w parowniku chłodziarki górniczej z czynnikiem R407C
    (2006) Filek, Krzysztof; Łuska, Piotr; Nowak, Bernard
    The main topic in this publication is connected with work of mine compression refrigerator with the refrigerant R407C. The publication includes the results of the change of temperature and air humidity, which are proceed in the evaporator. 45 variants were tested. This variants were differed in properties (temperature, relative humidity and flow rate through the evaporator). In the work are shown the results of 24 variants, for which the properties of air inlet are the most close to reality (excavations in the underground mines). Moreover, this publication includes the results of numerical calculations of precooled air parameters and the thermal power of evaporator. In this case all results of air parameters before precooling are used as the input data. The findings are compiled in the tabular form and in the shape of diagram.
