Summary

The paper presents the results of experimental investigations into the performance of a chiller equipped with an electronic expansion valve under steady state and transient conditions. The tests were carried out in the laboratory on a 25 kilowatt nominal capacity chiller both during cold start and hot start. For both start-up cases, the response of the chiller in terms of cooling capacity is very fast, leading to low on/off cycling losses. The superheat setting of the expansion valve influences both the transient and steady state performance of the chiller. Optimum refrigerant flow control can be achieved by integrating the control of the expansion valve into an overall microprocessor-based control strategy for the chiller.
