Predicting and assessing energy performance of refrigeration systems.

Prévoir et évaluer la performance énergétique des systèmes frigorifiques.

Numéro : 1105

Auteurs : PEARSON A.


Rising energy costs continue to motivate users of refrigeration to play close attention to the operating efficiency of their systems. In cold storage and distribution it is difficult to assess the effectiveness of improvement initiatives due to the large daily variations in system load and weather conditions. Specific Energy Consumption (SEC) is becoming more widely used, but it takes a long time to build an accurate assessment.
This paper presents a novel method of predicting annual SEC for cold stores, chill stores and distribution centres based on daily energy readings. Using measured data from various sizes and types of site the method was checked and a means of assessing the margin of error in the prediction was developed. A simple tool for evaluating the effect of maintenance and repair is presented.
Opportunities for extending the methodology to other types of refrigeration and air conditioning systems are considered.
