Abstract: This paper investigates the effect of refrigerant flow control on the steady-state and transient performances of refrigeration systems. The objective is to identify the effect of alternative expansion valves and design and control criteria on the energy efficiency of the system. The results indicate that a high valve-gain reduces the on/off cycling losses but produces high-amplitude superheat oscillations at steady-state conditions. Low valve-gain, on the other hand, increases the cycling losses but improves the stability of superheat control at steady-state conditions. For optimum performance, a variable-gain refrigerant flow-control device is required. Variable gain, together with other control refinements, can be implemented through the development of microprocessor-controlled electronic expansion-devices.
