Energetic performance of different expansion valves in a supermarket.

Author(s) : BOBBO S., CAMPORESE R., FEDELE L., et al.

Summary

Adopting electronic expansion valves in the refrigerated display cabinets of many supermarkets enables an appreciable energy saving vis-à-vis the same installations equipped with thermostatic expansion valves. This is due to the fact that electronic valves enable a lower condensation pressure in the systems with air cooled condensers, which is adjusted to variations in outside air temperature. This paper reports the preliminary results of an investigation conducted in a supermarket in central Italy where the display cabinets were operated alternately with thermostatic and electronic expansion valves.
