Across the globe, annual food loss amounts total to approximately 1.3 billion tons of waste and 4.4 gigatons of greenhouse gas (GHG) emissions. To put that in perspective: If food waste were a country, it would rank as the third largest GHG emitting country in the world, surpassed only by the United States and China. The average supermarket, which brings in about $35M in annual revenue, will see $526,590 worth of food waste and 3,600 MWh worth of wasted energy use, where about 2,000 MWh is used for refrigeration—the equivalent of 170 households. SaaS for temperature monitoring Clearly, there is both an economic and sustainability burden to food loss besides the revenue loss and environmental impact. Luckily, this burden can be eased when using Software as a Service (SaaS), like food temperature monitoring. Supermarkets who monitor their food temperatures will improve their margins and overall profitability by selling food at its full price rather than marked down due to over ripening or close to expiration date. This, in turn, will deliver improved customer satisfaction because supermarkets will be able to continue to stock fresh food while minimizing the sale of old and ripened provisions.Supermarkets who monitor their food temperatures will improve their margins and overall profitability There are many benefits of using SaaS to improve supermarket efficiency, which can help to reduce food waste and lower energy costs in countless supermarkets worldwide. Many of the roughly 50,000 food retail locations that utilize electronics controllers use some level of SaaS technology like Alsense Food Retail Services, the newest cloud offering from Danfoss Climate Solutions for supermarkets and food retail applications. Alsense Food Retail Services is a sustainable, scalable, and secure modern platform that delivers tangible data to improve operational and energy efficiency while optimizing the performance of food retail operations. Its technology is engineered to provide supermarkets with actionable insights that allow you to track refrigeration asset performance, respond to alarms, integrate 24/7 monitoring, reduce energy consumption, and more to deliver savings as high as a 40% reduction in food waste and 30% decrease in energy costs. Examples of food loss prevention with Alsense Food Retail Services The sensor in the meat fridge notices a high temperature and submits an alarm to the cloud The alarm is analyzed by the Danfoss Enterprise Service Team (Managed services) The reason for the alarm is determined and a service provider is contacted The service provider is dispatched to the supermarket to fix the issue in the meat fridge to avoid food loss Danfoss’ advanced algorithms detect if the refrigeration systems are running efficiently or if they are over consuming energy Alsense Food Retail Services is a sustainable, scalable, and secure modern platform that delivers tangible data to improve operational and energy efficiency while optimizing the performance of food retail operations aktiv & irma, a supermarket in North Germany, has shown significant savingsWithout SaaS, the store’s ROI will take much longer than if you rely solely on the hardware as part of the Alsense Food Retail Services pilot program. In collaboration with Danfoss, they installed a solar photovoltaic system, storage system, and a charging station for guests. All major assets in the supermarket system are linked through the Alsense Food Retail Services cloud to manage loads and eliminate unnecessary peaks to best use each store’s energy. Regulating energy levels is accomplished through a variety of methods that offer potential savings: Load shifting: As high as 20 kW in additional peak reductions ($1,758.30 potential savings). Compressor curtailment Solar: 112 MWh electricity produced ($16,410.80 savings) Battery: Grid demand reduced by 40 kW ($3,516.60 savings) Peak load shaving: Charging station is throttled if needed to maintain target max peak level in the store. ($2,344.40 potential savings) aktiv & irma saved about 15% in additional energy costs and reduced over 70 tons of CO2 for a total savings of $20,168.80 compared to other supermarkets. For supermarkets that are considering marrying SaaS with their hardware expenditure, the return on investment (ROI) will depend largely on their level of SaaS investment. Without SaaS, the store’s ROI will take much longer than if you rely solely on the hardware. To put it simply, the more robust the SaaS program, the quicker supermarkets will see a return on the overall system investment. Alsense Food Retail Services? A zero-net, even net positive, billable energy supermarket is possible. The prerequisites to make these savings happen are based on energy efficiency, particularly reducing overall consumption and onsite heat and electricity generation and storage. Energy arbitrage services can enable energy bill optimization. Essentially, this means that energy can be stored in a battery and used when prices in the grid are high.Precooling can also be used to cool down cabinets before prices increase Precooling (curtailment) can also be used to cool down cabinets before prices increase. Another option is to turn off compressors for as long as possible when the energy prices are high. This means temperatures will drift upwards, so turn on the compressors before the temperature compromises food quality. Lastly, supermarkets have further potential to balance the grid via fast Frequency Response, peak Load Shifting, and seasonal Buffering. SaaS technology, like Alsense Food Retail Services, is a strong compliment to hardware assets that can help supermarkets achieve higher profitability and food loss and waste reduction. If a supermarket aims to go zero- or positive-net, the solution is to invest in both hardware and SaaS.
Control Systems have always played an important part in the function of HVAC systems and for many years were centered around the safe and optimum performance of the hardware deployed. Every HVAC system is a closed-loop process, with inputs fed into control logic that determines the best course of action to achieve the desired output. Energy management and integration into Building Information Management saw the advent of energy-saving techniques like free cooling and night-time purge reduce mechanical cooling loads, whilst occupation data allowed greater holistic management of systems. These are well-recognized practices that are being refined using predictive weather data, additional focus on heat recovery and more environmentally energy sources. Control Systems have always played an important part in the function of HVAC systemsThe scope of the typical systems loosely described above are around the management of systems on one site and their operation and maintenance tends to be centered around that particular location. Multi-site Development & Management The UK temperature-controlled warehousing market tends to develop on a project-by-project basis that fosters the site-by-site focus of ongoing management and maintenance. For multi-site logistics operators and manufacturers and distributors with a multi-site portfolio. this approach has the following disadvantages: Disparate system KPI data collection and reporting Setpoint adjustment left to untrained operators who apply their individual assessment of compliance risk and often don’t consider the financial and operational implications of fine-tuning (or meddling) Enterprise-wide energy management is difficult to control Duplication of staff tasked with reporting and maintenance Inconsistency of measurement and interpretation Slow response to system failures Poor interpretation of operational processes that impact system efficiency Portfolio Management The distinction here is that a portfolio of temperature-controlled sites is managed centrally instead of independently. The enabler to the solution is the rapid Energy management and integration into Building Information Management saw the advent of energy-saving techniquesdevelopment of access control systems and data communication. The next step is vital in the customer engagement process; what do they want to see? What’s important and what is not? How often do they want to see it and in what format? From experience of going through this process this is a voyage of discovery for the warehouse operator in understanding the stakeholders in their business. Quality and compliance managers are the obvious starting point, facilities managers, finance managers who are tasked with reducing energy costs, customer service and the end customer. Alongside the KPI monitoring, Jet Environmentals created a hierarchy of alarms management that alerts the right people with system information, that triggers a sequence of actions driven by the data. Trends are monitored to predict where there might be a problem on the horizon so action can be taken before there is an issue. Faults and failures are alerted instantly and corrective action alerts sent to the right people. Conclusion The continuous development of HVAC controls and reliability of secure data connections has provided a means of improving performance, lowering cost and building trust in provider/user relationships. To be successful, the roll-out of such a project requires the willingness and collaboration of all parties and the groundwork defining stakeholder requirements is vital in defining a scope that meets expectations.
Many of us are spending more time at home. Given that work and home lives are becoming more intertwined, it makes sense to create a “comfort zone” in the place where people spend the most time. I am speaking about the benefits of zoned HVAC comfort control through duct-free split systems. Imagine offering your customers the ability to cool their bedroom at night without having to cool the whole house. Maybe they want to cool their home gym to 68 degrees while leaving the playroom at 76 degrees. Duct-free systems offer the ability to individually set preferred comfort settings for each individual zone or room in the home. Control the temperature, humidity and even the volume and direction of airflow, all according to personal preference. Imagine offering your customers the ability to cool their bedroom at night without having to cool the whole house Pandemic trends During the pandemic, one trend we are seeing is more consumers adding duct-free systems to spare rooms to function as a home office or the conversion of a garage for a home theater or as a social-distanced gathering place for family and friends. There are many options today to meet all of these needs and more. LG offers a variety of stylish, duct-free indoor units ranging from a smoked glass mirror finish to traditional white. You can offer your customers the ability to customize their space with the Art Cool Gallery, a unit that looks like a picture hanging on the wall, allowing them to add their own artwork or photographs. With so many options, there is no reason not to have the comfort you deserve. Each unit is powered by an energy efficient inverter with heat pump technology – some offering up to 28 SEER. The SEER calculates air conditioning and heat pump cooling efficiency. The higher the number, the less you will spend on energy costs. These systems – many of which are ENERGY STAR® certified – are built with cost-savings in mind, so whether it is low installation costs or reduced lifetime costs, your customers will be surprised to see the money they will save with duct-free HVAC technology. app technology “Smart” indoor units from LG come equipped with Wi-Fi capabilities and on some other models, this function can easily be added using a separate module. This allows control via the included wireless controller or from a smartphone. The free app for both iOS and Android is called LG ThinQ®. This is where we have a unique advantage over the competition. The app is the same communication platform used with LG home appliances and TVs. When a homeowner presses the “away mode” it will set all of the indoor HVAC units to their predetermined temperature, and at the same time other smart appliances in the home - refrigerator, dishwasher, washer and dryer - will be set to a low energy consumption mode. Imagine the savings! The app also allows the control of HVAC modes (Heating, Cooling, Dehumidification, Auto Changeover, or Fan Only), temperature, airflow direction/vane movement (up, down, side to side), fan speed and of course power (on/off). Users can control one or several units and each can be set up for group control. For instance, a parent might want to control all of the zones in the house, but only give children control of their room. Duct-free units give everyone their own personal level of comfort. There is also the option of installing these units in rooms that are typically warmer in the summer months or difficult to keep cool as temperatures rise. A connected home LG units can also be voice-controlled when paired with Amazon Alexa or Google Home For a more connected home, any of the LG units can also be voice-controlled when paired with Amazon Alexa or Google Home. This offers the convenience and freedom to use simple commands to set a desired temperature in various areas, such as: “Alexa, set the master bedroom to 70 degrees,” or “Alexa, set the office to heating.” So how does it work? The inverter compressor can adjust the speed of the compressor in 1 hertz level increments to match the load. This allows the outdoor condenser to operate at the minimum-required hertz level to meet the load and achieves a desirable energy efficiency at lower sound levels. The indoor unit also maintains greater cooling and wicks the moisture from the air to provide lower humidity levels. The reward is monthly energy savings on utility bills. These duct-free systems allow homeowners to efficiently make the most of all available spaces.
