    Ocena jakości pracy chłodziarki TS300 z wykorzystaniem statystycznej analizy danych
    (Wydawnictwa AGH, 2011) Łuczak, Rafał
    In the article, an analysis of air parameter validation, which is cooled by direct action cooler type TS300, made by Termospec Ltd., and influence of air parameters on a process of its cooling and refrigerating power of applied cooler were presented. A cooling efficiency was evaluated by statistical criteria in the form of multiple regression equations. In this work a statistical analysis of air and water parameters was shown and on this basis an estimation of evaporator and condenser input data was made. An application of obtained statistical equations allows in the simply and fast manner determine the cooled air parameters and makes possible to realize a simulation of evaporator and condenser powers in the relationship to input data validation in the places of forecast refrigerator localization.

    Zwalczanie zagrożenia temperaturowego w wyrobiskach górniczych chłodziarkami powietrza bezpośredniego działania typoszeregu TS
    (Wydawnictwa AGH, 2010) Łuczak, Rafał
    Problems connected with proper climatic conditions and opportunities of their improvement in terms of intensification of production, growth of depth and difficult geothermal conditions require a complex application of many means in order to assurance of suitable working conditions. The usage in polish mining the local refrigerating systems with direct action and with refrigerating power 300 kW and 350 kW is a leading solution of air treatment in the exploitation place. In this article parameters of work of direct action cooler located in the excavations of coal mine »Sosnica-Makoszowy« – »Makoszowy« were analyzed.
