A website managed by the Environmental Investigation Agency (EIA) and Greenpeace is seeking examples of energy-efficient equipment with natural refrigerants, such as ammonia/NH3 (R717), or installations of those products to add to its database, called Cool Technologies.
The aim of the database is to provide policymakers and end users with energy-efficient HVAC&R equipment that does not rely on f-gas refrigerants, thereby reducing energy costs and avoiding direct emissions of high-GWP gases.
The website gathers products and installations showcased and implemented around the world, relying on input from industry stakeholders. It divides products into three main categories: refrigeration, air-conditioning and heat pumps. Each category is further divided into domestic, commercial and industrial, plus mobile refrigeration and air-conditioning.
Many HVAC&R companies have already submitted their products to feature in this global database. OEMs with R717-based products that are featured on the website include Evapco, Mayekawa, and GEA.
Installation case studies of energy efficient R717-based equipment include an adsorption systems fueled with biomasses in India, a Scottish ice rink and ammonia-based heat pump and chillers serving a Danish hospital and local district heating and cooling.
Call for submission
In light of the current negotiations around the revision of the EU F-gas Regulation, as well as studies indicating that the Kigali Amendment objectives may fall short in achieving the objectives set in the Paris Accord, the two NGOs are calling for other R717-based products and case studies to be featured in the Cool Technologies database to prove that energy-efficient and natural refrigerant-based solutions can be found worldwide.
Submission to the Cool Technologies website is free of charge, and information can be provided through a user-friendly form at this link. Alternatively, interested stakeholders can get in touch with the EIA team to learn more about the project.
