ANNEX 56 INTERNET OF THINGS FOR HEAT PUMPS Introduction The increasing spread of digitalization will enable heat pumps, equipped with electronics, software, sensors and network connectivity, to participate in the Internet of Things (IoT). This can be at domestic building level or in an industrial plant. The ability to collect and exchange data and make use of it wisely will open new potentials for optimization and flexibility. Thereby heat pumps and digitalization can play a major role together to increase energy efficiency and introduce renewable energy into buildings and industry. With heat pumps and their components becoming con- nected devices participating in the Internet of Things, a variety of new use cases and services will be enabled. Such services and applications can be related to any part of the lifecycle of the heat pump. IoT-enabled heat pumps for household and commercial applications are serial products that are sold in large quantities. They pro- vide data that can be used for preventive analytics, such as what-if analyses for operation decisions, predictive maintenance, fine-tuning of operation parameters and benchmarking. They can be used for smart demand re- HPT TCP ANNEXES sponse to reduce peak load and to optimize electricity consumption, e.g., as a function of the electricity price (Figure 1). In contrast, industrial heat pumps are usually planned, manufactured and installed on a project-spe- cific basis by contractors and installers. Digitalization in industry can range from automated equipment, advan- ced process control systems to connected supply value chains. IoT-enabled heat pumps allow for integration in the process control system as well as a higher-level en- ergy management system, which can be used for overall optimization of the process. Each level of participation of a heat pump in a connec- ted world (Figure 2) is also associated to various signifi- cant risks and requirements for connectivity, data ana- lysis, privacy and security for a variety of stakeholders. Therefore, this Annex will have a broad scope, looking at different aspects of digitalization to analyze heat pump specific challenges and opportunities. Objectives The Annex focuses on opportunities and challenges of IoT-enabled heat pumps. Connected devices will play a major role in the future, addressing multiple aims, such as increased comfort for the user, reduction in energy consumption and decarbonization of heat supply. The re- sults of the Annex will be disseminated to relevant target groups, such as component manufacturers, heat pump manufacturers, associations and regulatory authorities, by means of tailored messages.
