Air conditioning system
Commercial air conditioning systems in offices, retail branches and data centres can be monitored remotely with IoT. Operators see energy consumption, temperatures and faults in one place, detect failing compressors or refrigerant shortages early and plan service visits precisely.

Commercial air conditioning: detect faults before it gets hot
In the solution examples, the PSsystec SMARTbox records energy consumption, temperature, voltage and operating status and sends the values via the cellular network to Deutsche Telekom's Cloud of Things, independently of the local network. For existing systems, the Arrow iCOMOX sensor box measures compressor vibration, because a compressor vibrates differently when refrigerant runs low. This data travels via NB-IoT, Power over Ethernet or a SmartMesh IP radio network into cloud analytics. Platforms on Microsoft Azure such as Johnson Controls OpenBlue Enterprise Manager or TwinWorX bring building services data together, while ICONICS software reads it via BACnet, OPC or Modbus and detects faults using a library of fault rules.
The examples come from retail, telecommunications, data centres and commercial real estate, mostly as energy monitoring and fault management. PASM, a Deutsche Telekom subsidiary, works with PSsystec to monitor the power supply and technical condition of more than 3,000 sites such as equipment and server rooms centrally and in real time. A retailer with more than 600 branches cut its energy costs by 5 to 10 percent with the PSsystec IoT Energymonitor, partly through demand-based control of its air conditioning. An HVAC service provider uses the Codestryke solution to plan its technicians' routes and avoid lengthy troubleshooting.

Commercial air conditioning: frequently asked questions
How can commercial air conditioning be monitored remotely?
Commercial air conditioning can be monitored using sensors and a gateway that sends readings via the cellular network to a cloud platform. This means the system also works at sites without their own Wi-Fi or LAN. At PASM, the PSsystec SMARTbox records energy consumption, temperature, voltage and operating status. Faults are detected automatically and forwarded to the responsible teams, and many parameters can be configured remotely. This saves on-site visits.
How can compressor faults in commercial HVAC be detected early?
Compressor faults can be detected early from its vibration behaviour. Failing compressors and refrigerant losses usually develop gradually until the temperature in the building rises noticeably. In the Codestryke solution, the Arrow iCOMOX sensor box measures compressor vibration, because a compressor without enough refrigerant vibrates differently from one that is fully charged. The service manager is notified and sends the technician out with the right spare parts.
How is server room air conditioning monitored?
Server and equipment rooms are monitored by feeding energy consumption, temperature and system status continuously into a central platform. PASM monitors more than 3,000 Telekom sites this way, with faults reported automatically. In NTT DATA's data centres, WAGO controllers monitor heating, ventilation and air conditioning systems and make the data available to an AI via Modbus. NTT DATA itself expects to use 35 to 40 percent less energy for cooling.
What does an HVAC monitoring system do for air conditioning?
A building services platform brings together data from all air conditioning systems, detects faults and alerts staff. ICONICS software collects data via BACnet, OPC or Modbus and checks it against a customisable library of fault rules. Johnson Controls OpenBlue supports remote monitoring of heating, ventilation and air conditioning. With TwinWorX, an air conditioning system transmits its refrigerant pressure into a digital twin about once per second.

Pump
Pump monitoring with IoT records vibration, temperature, pressure and energy consumption of running pumps. Operators detect damage and faults before a pump fails and plan maintenance by condition rather than at fixed intervals.
Compressor
With IoT, compressor maintenance follows actual condition: sensors record current consumption, pressure, temperature and running times. Operators detect creeping damage and unused running time early and cut energy and service costs.
Electric motor
Motor condition monitoring with IoT continuously measures the vibration, temperature and current draw of electric motors. Operators detect imbalance, bearing damage or winding faults early and replace motors based on condition rather than after a failure.
Packaging machine
OEE software automatically records run times, downtime, speed and rejects on packaging machines from the machine signals. Operators see where their lines lose performance, and machine builders use the same data for remote access and digital services.
Refrigeration system
A refrigeration monitoring system makes service plannable: temperatures, refrigerant circuit pressures, compressor status and energy consumption flow into a platform in real time. Operators and service partners detect faults early, avoid unnecessary site visits and reduce excess consumption.
Injection moulding machine
A connected injection moulding machine continuously supplies data on mould cooling, cycle time, electricity and compressed air. Plastics processors use it to cut energy use and scrap, detect faults earlier and bring machines from different makers onto one data basis.
