WebTo adapt the cooling capacity of the evaporator to the current cooling load of the cooled space, a number of control elements are used. The paper proposes a new method of regulating the cooling capacity for a one-stage refrigeration cycle with the R-744 refrigerant and an internal heat exchanger (IHX). Web29 de nov. de 2012 · A steam control valve that controls down to 2%, 3%, or 4% of heat exchanger size is required. Most steam valves control down to 40% of their full load consistently, and up to 80% of their full load. To control down to 2% would require a valve 5% or 1/20 of the steam exchanger size. A 1/3 valve is over six times larger than …
