As the planet continues to warm over the next three decades, air conditioning will be one of the few home applications in the U.S. that will increase its consumption of energy in 2050 compared to 2017, but this will be mitigated by the growth of green HVAC technology.

So observed Raphael Chalogany, general manager of U.K. market research firm BSRIA, in a presentation last month at the AHR Expo in Atlanta.

Chalogany referred to a U.S. Energy Information Administration chart showing that annual air conditioning…

The Kigali Amendment, an agreement to phase down HFCs globally, to the Montreal Protocol was adopted by 197 parties meeting in the Rwandan capital on 15 October 2016. The Amendment sees developed countries take the lead on phasing down HFCs, starting with a 10% reduction in 2019 and delivering an 85% cut in 2036 (compared to a 2011–2013 baseline).

Developing countries are split into two groups. The first one — which includes China and African nations — will freeze consumption of HFCs by 2024, with their first reduction…

Delhaize Serbia, the country’s leading retailer, has opened its first CO2 transcritical supermarket. The store, located in Belgrade, opened on 7 November 2018.

“Now we are capable of implementing CO2 transcritical, and we will definitely go in that way for the future,” Duško Pantović, expert associate for refrigerant installations at Delhaize Serbia, told Accelerate Europe magazine.

Danish CO2 transcritical rack manufacturer Advansor provided the rack system. Danfoss, another Danish multinational, helped with the system design — working together with…

In an effort to improve the safety of ammonia refrigeration in ice rinks Accent Refrigeration Systems, Victoria, B.C.,plans to install a “new style” ammonia system at a rink in Port Alberni, B.C., next summer.

A key element is improved airflow. “So if there is a leak you can get the ammonia out of the air quickly,” said Art Sutherland, president and CEO of Accent Refrigeration Systems, a major designer and installer of ice rink refrigeration systems.

“If there is a leak you can get the ammonia out of the…

This week (26 November), the European Commission launched an ‘in-depth investigation’ into the acquisition by Nidec of Embraco.

The two companies are leading global suppliers of hydrocarbon-based household and commercial refrigeration compressors.

Nidec, which bought SECOP — another leading supplier of hydrocarbon compressors — in 2017, purchased Embraco from white goods manufacturer Whirlpool for $1.08 billion (€890 million) in April.

“Refrigeration compressors are used not only in commercial applications but also in our homes, in fridges and freezers,” said EU…

“Through electrification [of vehicles], I’m confident CO2-based MAC [mobile air conditioning] will make its mark,” said Michael Matthias, general manager, head of engineering, at Sanden International, which makes CO2 compressors for mobile air-conditioning systems.

He shared his views at ATMOsphere Europe 2018 (which was organised by publisher of this website shecco) in Riva del Garda, Italy, held on 19–21 November.

How will electric vehicles (EVs) increase the uptake of CO2 MAC? As Matthias explained at the natural refrigerants conference, it will only be possible to make a vehicle’s battery last longer — and thereby maximise the driving…
