Connected refrigeration: Digitalization solution for air conditioning and refrigeration technology

Requirements management and technical specifications for an interconnected maintenance solution for air conditioning technology

Initial situation and problem

  • Customer service for stationary air conditioning systems is increasingly supported by connected solutions
  • The customer wishes to make the appropriate offer to their end customers - specialized companies for refrigeration and air conditioning technology
  • The offer should allow for the automation of maintenance (condition-based maintenance)

mm1 approach and solution

  • Assistance with designing the business model (value proposition, price structure, etc.)
  • Design a promising go-to market approach in the context of a previously three-step sales model
  • Perform technical requirements management and design the architecture of the connectivity solution
  • Prepare the detailed technical specification for the RfQ process


  • A new digital business model (freemium offering with monetizable premium services) has been designed and tested with market players
  • A connectivity solution for essential consumer devices and for sophisticated use cases (e.g. connectivity in cellar rooms) has been designed
  • A technical specification in the form of a detailed specifications sheet has been prepared (incl. BoM for essential components)
