Abstract
The paper considers the impact of various temperature hysteresis bands on the projected annual energy consumption of a domestic refrigerator when operating empty of product and with an internal product (comprising of 10L of water). Measurements from an IoT system employing a NodeMCU-based Generalized Predictive Control scheme, are used to support the study. A ThingSpeak platform and Smart Wi-Fi plug is used to realize the different temperature hysteresis bands whilst maintaining a given mean nominal internal temperature. Experimental measurements are taken from an IGENIX IG 3920 refrigerator. Results show that by judicious choice of hysteresis band, which is shown to be dependent on the internal product characteristics, annual energy savings of up to 20% can be obtained compared to worst case fixed hysteresis band scenarios.
