Monitoring HVAC in critical environments

The customer is a major general hospital

Addressed business problem

Today, the hospital runs multiple HVAC systems. Typically, each system has its own basic, local and individual supervision. Ensuring continuous service of the HVAC systems is considered a crucial factor for the overall operation. A failing system may cause severe impact resulting in increased cost and even human suffering.

The operations and maintenance organisation of the hospital needed improved control. They also needed easy-to-use visualisation to quickly identify and preempt any malfunction.

Solution

Free2move proposed a modular solution that fully utilises existing investments in control systems, complemented by Free2move's wireless sensors to provide a comprehensive overview . By use of Free2move's 2Connect™ platform; including the information from sensors such as monitoring of air pressure, differential pressures, temperature of fan engines, rotation speed of fan engines, power consumption of fan engines, vibration of fan engines; a complete visualisation of system health is provided.

Results

By the implementation, the customer has gained a modular, agile and reliable solution, supporting

  • Reduced operational cost
  • Reduction in needed site visits and on-call staffing
  • More accurate and pro-active maintenance planning
  • Increased customer satisfaction by higher mean time between failure (MTBF)

Products employed in this solution

  • Differential pressure sensors
  • Barometric pressure sensors
  • Air-flow sensors
  • Engine block temperature sensors
  • Engine current consumption sensors - also used for calculation of energy consumption
  • Engine rotation sensor (tachometer)
  • Engine vibration sensor
  • Ambient room temperature sensors
  • Ambient room humidity sensors
  • Celebes gateways
