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

Ciprés kicked off the webinar, emphasising the importance of staying abreast of regulatory trends in air conditioning and refrigeration.

The agenda for the session was structured to provide valuable insights, interactive elements, and a glimpse into CAREL’s latest white paper on heat pumps. Despite the overwhelming response with over 400 participants and 150 questions, the team assured attendees that while not all queries could be addressed during the session, responses would be shared via email in the coming weeks.

Participants were introduced to the webinar’s format, which included interactive polls and a game component designed to test knowledge about heat pumps. The game offered enticing prizes for the top performers, fostering engagement and competition among attendees.

A key feature of the webinar was the interactive element facilitated through a live polling platform. Attendees were encouraged to join in using a unique code, allowing them to participate in polls and quizzes, enhancing their learning experience.

Exploring decarbonisation with heat pumps

As the webinar continued, participants delved into the crucial role of heat pumps in decarbonisation efforts worldwide. With the imperative to combat climate change and meet the goals outlined in the Paris Agreement, heat pumps emerge as a key solution to reduce CO2 emissions. Ciprés highlighted how heat pumps offer a sustainable alternative to fossil fuel boilers, potentially slashing global CO2 emissions by a significant margin.

Despite their potential, heat pumps currently constitute only a fraction of the global HVAC market. Galenda shared insights from the International Energy Agency, indicating that merely 10% of buildings worldwide are equipped with heat pumps. To achieve broader adoption and reach the ambitious target of 20% penetration by 2030, concerted efforts are required, including substantial investments and overcoming various challenges.

The discussion then turned to the classification of heat pumps based on their external exchanges. Attendees learned about the three primary types: air source, water source and ground source. Each type harnesses renewable energy, contributing to decarbonisation efforts. While air source heat pumps offer simplicity and lower installation costs, their performance is subject to fluctuations based on outside temperatures. Conversely, water source heat pumps provide consistent performance but require careful consideration of water flow and characteristics. Ground source heat pumps offer stability throughout the year but entail higher installation costs and complexities.

Participants gained insights into the advantages and disadvantages of each heat pump type. Air source heat pumps offer ease of installation but are susceptible to performance fluctuations and ice formation. Water source heat pumps deliver consistent performance but demand meticulous planning and may incur higher installation costs. Ground source heat pumps provide year-round stability but come with significant upfront investment and implementation challenges.

As the first segment concluded, attendees gained a deeper understanding of heat pump technology and its pivotal role in decarbonisation efforts. Despite challenges, the potential for widespread adoption remains promising, driven by advancements in technology and growing environmental consciousness. By embracing innovation and collaboration, stakeholders can pave the way for a sustainable HVAC landscape, where heat pumps play a central role in mitigating climate change and achieving carbon neutrality.
