The worldwide online database “Cool Technologies” searches for examples of products and installations based on R744

A website run by the Environmental Investigation Agency (EIA) and Greenpeace is looking for examples of energy efficient equipment with natural refrigerants, such as CO2 (R744), or installations of these products to be added to its database, called Cool Technologies.

The purpose of the database is to provide policy makers and end users with references on energy efficient HVAC&R equipment that does not depend on fluorinated gas refrigerants, thereby reducing energy costs and avoiding direct gas emissions. strong PRP.

The website brings together products and installation examples from around the world, drawing 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, as well as mobile refrigeration and air conditioning.

Many HVAC&R companies have already submitted their products to be included in this global database. OEMs with R744-based products that are featured on the website include Advansor, Emerson, Enex, Epta, Fenagy, Panasonic, SCM Frigo, and Teko, among others.

Case studies of energy efficient R744 equipment installations can be found on three continents and include a chiller for an Alaskan microbrewery, several European commercial refrigeration installations, and the first commercial refrigeration systems in the Middle East and in Malaysia. Examples of domestic heat pumps from Reftronix and Denso/Vattenfall are also featured in the database.

Call for submission

In light of the current review of the EU F-Gas Regulation, as well as studies indicating that the objectives of the Kigali Amendment may not meet the objectives set out in the Paris Agreement, the two NGOs call other R744-based products and enclosures studies to be included in the Cool Technologies database to prove that energy-efficient, natural refrigerant solutions can be found worldwide.

Submission to the Cool Technologies website is free and information can be provided via a user-friendly form at this link. Alternatively, interested stakeholders can get in touch with the EIA team to learn more about the project.
