Heat pumps are becoming increasingly popular in the HVAC industry due to their efficiency and versatility. In this webinar two experts delved into the intricacies of heat pumps, shedding light on key trends and regulations shaping the market:

  • Miriam Solana Ciprés from CAREL’s Knowledge Center, responsible for following regulations and trends in HVAC
  • Matteo Galenda, application specialist HVAC Residential

Exploring market trends and refrigeration components

Attendees learned about the dominance of air-to-air heat pumps in the global market, constituting approximately 80% of installed units worldwide. However, there has been a notable shift in recent years, with air-to-water heat pumps emerging as the predominant choice in certain regions, particularly in Europe. Insights from the European Heat Pump Association highlighted this evolving trend, underscoring the importance of monitoring market dynamics to anticipate future developments.

Galenda provided a detailed overview of key refrigeration components, essential for the functionality of heat pump systems. Participants gained insights into the roles of components such as condensers, expansion valves, compressors and four-way valves in facilitating heat transfer and refrigerant circulation. The discussion emphasised the significance of electronic controllers in regulating system operations, alongside advancements such as DC compressors with permanent magnets for enhanced efficiency.

Throughout the webinar, interactive quizzes kept participants engaged and challenged their understanding of safety standards, refrigerant regulations and system components. Attendees showcased their knowledge by accurately answering questions related to refrigerant restrictions, market trends, and the functionalities of key components. The quizzes fostered a dynamic learning environment, enabling participants to test their comprehension and reinforce key concepts discussed during the webinar.

The interactive nature of the webinar facilitated engagement and knowledge sharing among participants, highlighting the collective effort to drive innovation and sustainability in the HVAC sector.

Question: ‘How do changes in F-Gas regulations affect the heat pump market?’

Response: The changes in F-Gas regulations, particularly the latest revision, will indeed have a significant impact on the heat pump market. Here’s how:

Phasedown of F-gases: The revised regulations include a strong phasedown of fluorinated refrigerants, aiming to reduce their usage over time. This phasedown will directly impact the availability and usage of certain refrigerants commonly used in heat pumps.

Specific bans on heat pumps: For the first time, specific bans on certain types of heat pumps are being introduced. These bans vary based on the type of heat pump, whether it’s a monobloc or split system, and the nominal capacities. These bans are set to come into effect in the near future, with different timelines for implementation depending on the type and capacity of the heat pump.

GWP limits: The regulations also set limits on the Global Warming Potential (GWP) of refrigerants that can be used in heat pumps. This means that heat pump manufacturers will need to ensure that the refrigerants they use meet these GWP limits, which may require transitioning to alternative refrigerants with lower GWPs.

Ban on certain refrigerants: Some fluorinated gases will be completely banned under the revised regulations. This adds urgency for manufacturers to transition away from these banned refrigerants and adopt alternatives that comply with the new regulations.

Challenges and opportunities: While these regulatory changes present challenges for the heat pump market, such as the need for redesigning systems and transitioning to new refrigerants, they also create opportunities for innovation and market growth. Manufacturers will need to adapt to these changes by developing more sustainable and environmentally friendly heat pump solutions.

Overall, the revised F-Gas regulations signal a significant shift in the heat pump market towards greater sustainability and environmental responsibility. Manufacturers, policymakers and stakeholders will need to work together to navigate these changes and ensure a smooth transition to more eco-friendly heating and cooling solutions.
