CHILLER UNIT ENERGY SAVER (CUES)
Refrigeration systems can account for as much as 40% of some businesses total energy consumption (quoted by the Carbon Trust). A refrigeration system commonly runs cycles of cooling which switch on and off according to the fluctuations in air temperature, wasting money by making the unit work harder than it needs to.
The theory of refrigeration is simpleâ€¦ by maintaining the temperature of the â€˜airâ€™ inside the cabinet at a preset level it is anticipated that the food will also take on the same temperature. However, because air has a completely different thermal characteristic to almost all food products it is quite normal for the owner/operator to routinely take temperature samples of the stored food products via a hand held probe to ensure food is correctly preserved.
Soâ€¦ we know that â€˜airâ€™ temperature is not an accurate measure of â€˜foodâ€™ temperature. Air entering a refrigerated space has very little thermal energy compared to the significantly greater thermal mass of most food products, and yet each time a door is opened and warm air comes into contact with the thermostat, there can be a fairly immediate response which leads to the compressor being energized even though the temperature of the food has not changed.
GREENEnergy has a SMART solution â€“ CUESÂ â€“ which is a range of temperature monitoring products designed to improve the efficacy of refrigeration systems by up to 40%, plus improve equipment performance and reliability – at the same time providing more accurate control of the temperature of stored food products.
