    Moc cieplna wymienników górniczej sprężarkowej chłodziarki powietrza
    (Wydawnictwa AGH, 2009) Nowak, Bernard; Filek, Krzysztof
    This article applies to mine compression refrigerator of air. In this article, work of refrigerator with or without inner regenerative heat exchanger (subcooler) is considered. The equations are given, from which thermal powers of evaporator, condenser and subcooler of refrigerator are determined. Focused character of all elements of refrigerator is assumed (expect specified, compressor and expansion valve also). For refrigerator with subcooler, system compound with 12 algebraic equations is received, in which unknowns are: temperature and humidity of cooled air, temperature of water after the condenser and temperature of refrigerant in five characteristic points of its circulation and ariolity degree of refrigerant of evaporator's inlet. For refrigerator without subcooler, the system is composed of 9 equations with the same as before unknowns, with the exception of 3 equations refer to subcooler.
