Reducing Costs and Acting Sustainably
Aachen, Sept. 1, 2009 – About 65 percent of the total power consumption in supermarkets is related to cooling, thus resulting in high saving potentials for optimization measures. It not always has to be the new acquisition of state-of-the art cooling devices. GesySense® by Aachen based Gesytec GmbH provides a complete, radio-controlled system for monitoring and energy efficient control of existing installations. No matter if chest freezer, wall mounted chiller cabinets or entire cold storage rooms – all cooling devices thus can be operated close to the temperature limits. Waste of energy can be avoided and existing installations remain in operation longer – saving costs and providing a sustainable supermarket operation.
„To achieve energy savings of up to 15 percent with GesySense in cooling alone is absolutely realistic“, says Dieter Schunk, Gesytec’s CEO. „First installations affirm the efficiency of our system. In combination with other optimization measures such as intelligent ventilation or illumination of cooling equipment the waste of energy can be cut-down further, thus preserving the environment and avoiding needless costs.“
The legal regulations for foodstuffs cooling provide clear limit values. In order to observe them in any case cooling systems are mostly operated according to the worst case principle: The cooling is set the way to comply with the regulations even under the most inappropriate conditions – settings that are entirely unnecessary in normal operation and result in extremely increased energy costs. GesySense provides supermarket owners with a simple means enabling them to centrally capture the actual temperature of even older installations in short intervals and to use this data for operational optimization of the units. Thus too much cooling is eliminated saving energy, monitoring and observing set points. Furthermore the normal operation of all devices is constantly monitored.
The GesySense system consists of several components. First to mention the battery operated sensors. Those wireless modules whose housings meet the requirements for foodstuffs are attached to the relevant measuring points requiring no cables. Their batteries are designed for a life cycle of at least 5 years. The temperature sensors meter in intervals of 5 minutes, covering a range from -30 °C to +50 °C, with an accuracy of 0.3 °C. Digital sensors, additionally available, monitor for example door contacts or capture the data of consumption meters – further information to trace faulty functions and for energetically optimized control. Furthermore the load status of the battery is transmitted along with the current value in order to prematurely detect a possible failure.
All measurements are simply transmitted to a receiver by radio, where information about the reception quality is added and finally transmitted to a data logger. This data logger connects the system to the central IT where finally all messages are evaluated, storage temperatures continuously logged and, if necessary, generating alarms.
Data capturing is not limited to cooling devices. Other sections such as vegetables, chocolates, storage rooms or just common reference points can also be provided with sensors, thus contributing to capture the complete situation within the store. The radio supported systems also facilitates the integration of sporadically used or flexible spots such as for special promotions: Place sensor, parameterize, done.
Entire supermarkets are energetically monitored; losses are minimized and saving potentials are optimally deployed with GesySense, simple and flexible. Existing cooling equipment is refurbished and limbered up to comply with the requirements of the future – cost efficient and sustainable operation within the store.
