IOT in HVAC and M&E Applications

IOT in HVAC

 

IOT is all the rage and is being rolled out across many different industries and applications and some OEM manufacturers are incorporating the smart communication capabilities that IOT offers across a number of wide and varied devices from Hand Driers to Trains, but what about IOT in HVACR and M&E applications?

For many it’s considered as a new technology and they are taking a “wait and see” type approach before committing to the technology and its uses, especially with the different potential applications. Indeed, many don’t want to their sites be considered as “Guinea Pigs” trial sites. To some extent that is understandable.

However, at the other end of the spectrum there is an ever present need for Facility Managers to keep reducing operational PPM and Reactive maintenance costs, Energy Consumption, improve occupants’ wellbeing, and improve on equipment reliability.

It’s only a matter of time before the rise in smart building technology offers innovative ways to meet these demands.

Smart building – IOT technology in HVACR applications is already here and offers exactly that. Sensors can be installed on anything that doesn’t currently have any communication capability to improve the understanding of the sites and M&E equipment you manage.

We can monitor everything from water tank levels, fridges, freezers, water pump belt condition, air filter condition, refrigerant leaks etc. In fact anything that could impact on Business operations, profits and continuity.

Imagine the impact on a Restaurant if one of the fridges were to fail. Not only would the stock be lost, you would then lose Sales, Customers and you would have to buy new stock after having paid to repair the failure. If that could have been prevented before the failure then the benefits are obvious.

With this knowledge and equipment condition plus live alarm conditions, we can truly offer condition-based maintenance, rather than those dictated by SFG20, in addition with this knowledge we can optimise the operation of central HVAC systems, so they become more energy efficient, and improve the overall working environment.

By regularly pulling back this enhanced data from well applied sensors allows the contractor and occupier/customer to use the information from the sensors into a series of live dashboards. We can easily fine-tune the building information management to fulfil the needs of different occupants across multiple buildings.

SAVING ENERGY

Energy saving opportunities have often been hard to identify due to a lack of non-technical understanding in complex BMS systems especially with legacy BMS systems coupled with an understanding of HVAC functions are often to blame.

A lack of visibility into the individual operation of the central HVAC equipment plant has made it difficult for Building managers in making quick, informed decisions about issues that could have a significant impact on energy consumption.

Marketing 4’s HVAC IOT Smart building systems solves these problems. Our web based Remote accessible Monitoring system, integrates with our specially applied HVAC sensors to pull back data and analyse condition-based asset performance data to provide real-time, non- technical reports.

IOT Handheld

These retrofit solutions identify HVACR plant inefficiencies equips occupier, contractor or both with the ability to reduce energy consumption quickly and easily.

The impact on Utility spending in Commercial Buildings is directly correlated with ever changing tenant/occupier requirements mixed with HVACR plant often being switched to manual, will result in the usage problems between the original building occupancy and BMS set-up. With the IOT smart building technology, these inconsistencies can be quickly identified, allowing the Main HVACR equipment to operate within the ideal timeframes.

CONDITION BASED HVACR MAINTENANCE

HVAC IOT Smart building technology enables both occupiers and contractors to move away from traditional models of M&E maintenance such as SFG20 to a condition-based system.

Rather than the customer contacting a contractor that uses the traditional planned maintenance model or waits for an occupier to call in with an HVACR failure, we can use the IOT data from our specially applied and selected HVACR sensors to identify proactive maintenance requirements before they become a problem and then fail.

This proactive condition based HVACR maintenance approach to maintenance means we can improve asset lifecycles as well as reduce unnecessary checks on equipment that is hopefully performing to the required standard.

In fact, HVAC Contractors can move away from the needs of SFG20 to providing their customers with a more informed process before things go wrong. For example, by monitoring refrigerant pressures on Chillers, VRF and Split Systems we can identify that a refrigerant circuit is low on refrigerant and attend site to find and fix the leak before the system fails causing issues for occupiers and their customers. Additionally, we can predict when filters need changing, so they are replaced only when they need to be.

Tenant wellbeing can be severely impacted by issues with Temperature, Air quality and lighting quality.  Poor air quality can have a severe impact on the ability for employees to concentrate properly. Room temperature imbalances is also a constant point of contention, especially with those on the sunny/shaded side of the building and FMs are often forced to deal with complaints.

With the technical advancement of IOT sensors and their HVAC applications helps Businesses to solve these problems and improve the service delivery. As sensors become smaller and more powerful, we have more opportunities to monitor our buildings in a discreet and non-intrusive way.

We can maximise the information available from HVAC equipment such as temperature, pressure, liquid levels, Air Quality etc, to improve occupier wellbeing, alleviate room temperature disputes, inform contractors of impending problems, and so much more.

Summary

To summarise, automation is already enabling HVACR Businesses to improve efficiencies. As technology evolves these smart HVACR sensors in IOT systems will flag system errors or operational inconsistencies and log reactive tasks autonomously, before occupants or tenants report the issue.

With the opportunities HVACR IOT sensor technology provides, we will know what is happening when and why, allowing our systems to inform everyone involved with the building, engage with maintenance providers, ensure work is completed, reduce the risk of failure and improve the whole customer experience.
