The European building market needs a radical shift towards sustainable thermal energy systems: Heat Pumps play a pivotal role in replacing gas boilers in multi-family houses, combining ease of installation, modularity, ecological refrigerants, compact thermal storage and acoustic optimisation.

To exploit to potential of Heat Pump systems in residential application, there is a need for optimal design and operation. While numerous theoretical studies exist, there are few experimental studies that demonstrate the potential. We validate optimal design and operation in our VCLab.

Within the „WP-QS im Bestand” research project, up to 75 air-source and ground-source Heat Pumps in single-family houses built between 1826 and 2001 are being detailed measured under real conditions. The contribution includes interim results of an efficiency analysis for around 40 to 50 Heat Pumps.

Heat Pumps are key to the EU’s carbon neutrality goal by 2050. Integrating comfort and energy management in residential applications makes this transition sustainable, reliable and optimal to users.

The presentation gives an overview on the findings of IEA HPT TCP Annex 56 that analysed opportunities and challenges of IoT and digitalisation for Heat Pumps in more than 40 case studies of various IoT products and services.

We will discuss the recent and expected growth in Heat Pump adoption and how smart controllers make Heat Pumps even more efficient. Real case studies of Heat Pumps and how Heat Pumps are lowering energy bills. We will tell how AI and data optimize Heat Pumps energy consumption.

A spreadsheet-based planning tool is developed for the evaluation and comparison of different thermal renovation variants and Heat Pump solutions for multi-story residential buildings. The techno-economic evaluation and optimization allows design recommendations for specific or cluster of buildings.

The lecture presents partial results of the development of a high-temperature Heat Pump within the framework of the large joint project KETEC (Research Platform for Refrigeration and Energy Technology) between University of Chemnitz, Fraunhofer ISE Freiburg and the ILK Dresden.

Application of steam compressors in Heat Pump cascades achieve high temperature output by the usage of natural refrigerants thus avoiding environment harming substances which were needed previously. Experiences in integrated Heat Pumps in refrigration cycles are getting more widespread.

In this presentation current challenges for sucessful integration of high-temperature Heat Pumps, technical and regulatory will be discussed.
In addition a short market overview on process heat demand and supplier of HTHP will be given.

Turboden Large Heat Pumps’ features will be presented together with potential innovative implementations. In addition, some reference cases for both district heating and industrial applications will be described.

This presentation will introduce the development of various high-temperature Heat Pump technologies using water, HC’s, and R-744 as working fluids. 6 different demo-systems will be presented, and a status from on the latest testing activities in the HTHP laboratory at DTI will be given.

The Plus project in Magnor, Norway, in collaboration with Enrad and Frascold, aims to create an eco-friendly furniture factory. Enrad R-290 Heat Pumps equipped with Frascold compressors for hydrocarbons play a key role in reducing greenhouse gas emissions. The project exceeds emission reduction goals.

The role of large capacity Heat Pumps in de-carbonizing cities across Europe.

The presentation will cover the objectives and status of the EU-funded SPIRIT project that will demonstrate three full-scale (> 0.7 MW_th) industrial Heat Pump systems upgrading waste heat to valuable temperatures (135-160 °C) in the paper & pulp and food & beverage industry.

Our focus is on the significance of certification in ensuring high performance and energy efficiency standards. We highlight tangible benefits like reduced energy consumption, lower emissions, improved indoor air quality, and cost savings.
