Cooling to the Green Deal with natural CO2 refrigerant systems

WELSHPOOL, United Kingdom, 17 August 2021: Invertek Drives showcased its dedicated VFD, Optidrive Coolvert, for use on CO2 refrigeration display cases used in the retail sector. The company added that its Optidrive Eco operates on larger current refrigeration compressor racks and cold rooms.

Invertek make the announcement against the backdrop of the European Commission’s Green Deal, also referred to as Fit for 55, which sets out proposals to cut EU net greenhouse emissions by at least 55% by 2030, compared to 1990 levels. This could mean the current target of reducing fluorinated greenhouse gas (F-Gas) emissions by two-thirds by 2030, compared with 2014 levels, will be adjusted and tightened further.

The EU F-Gas Regulation brought a 44% reduction in the amount of available HFCs in the EU, compared to 2015. By 2030, the current regulation allows only 20% of HFCs being available, with stepped drops between then and now. This could change in the recast.

According to Invertek, the impact of both means there is a need to ramp up the use of natural refrigerants, such as CO2, in cooling and refrigeration systems. And this isn’t just in the EU but throughout the world as part of the existing Kigali Amendment to the Montreal Protocol, it said.

Variable frequency drives (VFDs), the company said, are playing an important role in reducing emissions and energy use in HVAC&R systems. Optidrive Coolvert, it said, is one of the smallest VFDs in its class providing OEMs with opportunities to reduce panel space and lower machine costs. It fits directly into refrigeration display cases alongside a CO2 compressor, it added.

This is in addition to end-user savings of up to 25% using CO2 refrigerant condensing systems, which it is specifically designed to work with, the company claimed. A combination of meeting EU F-Gas Regulations and cutting energy use is a significant benefit for the end-user as well as for the environment, it said.

Mike Carman, Head of Sales, Invertek Drives, said: “The recast of the F-Gas Regulation comes as the EU sets out its new and wider environmental ambitions through the Green Deal. It’s widely believed this is the precursor to a significant adjustment in the F-Gas Regulation timeframe.

“With either more cuts in the amount of HFCs available in the EU or increased limits on emissions, it’ll impact on the manufacturers and end-users of refrigeration and wider HVAC/R systems”

According to Invertek, the Optidrive Coolvert also has the widest ambient operating range of between -20 degrees C and +60 degrees C, making it ideal for use in a wide range of environments. It can be used for the control of CO2 ­­­­rotary or scroll, BLDC compressors used in supermarkets and convenience store display cases; heat pumps, and condensing units, the company said. This is in comparison to the Optidrive Eco VFD, which operates on larger-capacity semi-hermetic and screw compressors used in industrial and food retail refrigeration racks, and chillers, the company added.

According to Invertek, Coolvert is compatible with all motor types, including induction motors, permanent magnet motors, brushless DC motors, synchronous reluctance motors and Line Start PM motors ranging between Single Phase (Active PSE) 7A and 20A, and Three-Phase 14A to 24A (input of 200V to 480V).

Its open Modbus RS485 communication, the company said, ensures seamless connection to any external application controller, allowing the OEM freedom to select which components to use, which again helps lower manufacturing costs.

With an IP20-rated front and an IP55-rated rear, its panel mounting allows the drive’s power electronics to be cooled by the chilled air of the condenser, the company said, adding that this allows OEMs to select the smallest panel size for the control of the electronics, while removing heat generated by the drive and maintaining the IP rating.

AHRI Board approves decarbonization general position statement

ARLINGTON, Virginia, 18 May 2021: The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) on May 14 released a General Position Statement on Decarbonization, advancing the association as a resource for states and localities grappling with how to successfully, sustainably and affordably reduce emissions related to the built-environment.

AHRI revealed the paper as noting, “The air conditioning, heating, ventilation, refrigeration, and water heating industry has a long history of providing innovative, high-quality, energy-saving, affordable products that enhance the comfort, safety, health, and productivity of businesses and people around the world”. It expresses AHRI’s support for “the ongoing, science-based transition to a lower carbon society, in which consumer choices for heating, cooling, water heating, and commercial refrigeration are the most energy efficient, environmentally beneficial available anywhere in the world, while maintaining appropriate and adequate levels of safety, health, comfort, and affordability”.

Stephen Yurek, President & CEO, AHRI, said: “Our member companies – which have more than 100 years of experience and expertise in product solutions, technology, and innovation – can serve as a valuable resource in helping the nation achieve a lower carbon society.”

The statement, AHRI said, comes on the heels of the success of the American Innovation and Manufacturing (AIM) Act, passed by Congress in 2020, which provides authority to the Environmental Protection Agency to regulate the production of high-global warming potential hydrofluorocarbons and establishes a national phase down structure for the refrigerants that are widely used in air conditioning and refrigeration equipment. That effort, AHRI said, more than 10 years in the making for the industry, is forecast to ultimately result in a 0.5 degree reduction in global temperatures over the next 30 years, even as it creates jobs and helps the industry’s global trade posture.

Supreme Court in Canada endorses climate action to protect future generations

VANCOUVER, British Columbia, Canada, 25 March 2021: Not-for-profit legal firm, West Coast Environmental Law applauded the March 25 decision by the Supreme Court, upholding Canada’s price on carbon pollution, which confirmed the ability of all levels of government to take action to address the climate crisis, consistent with the overarching responsibility of the Canadian government to ensure that youth and future generations inherit a healthy atmosphere.

In light of the decision, the legal organization urged the Canadian government to ramp up its climate ambition and to strengthen and enact Bill C-12 without delay to ensure that Canada meets its future climate goals.

“Canada has missed every climate goal it has set for itself, in large part because of inconsistent and half-hearted efforts by both federal and provincial governments,” said Andrew Gage, Staff Lawyer at the firm. “This decision makes it clear – the buck stops with the federal government. The Canadian government must work cooperatively to encourage provincial action, but it can also step in when provinces fail and take the steps required to protect Canadians from climate change.”

Lawyers at the firm said the legal victory has the potential to result in environmental benefits well beyond climate action. “It is a landmark decision for the environment,” said Anna Johnston, Staff Lawyer. “By rejecting the provinces’ attempts to minimize federal authority over climate, the Supreme Court has made it abundantly clear that when it comes to environmental protection, we need all hands on deck.”

Warned Dr Silvie Harder, Climate Scientist: “Canada is warming at twice the global average – leading to increased floods, wildfires and other climate disasters. With today’s decision, the Canadian government is well placed to increase its climate ambition, bring our fossil fuel addiction under control and align with what the global scientific community says is needed to keep Canadians safe.”

Lawyers at the firm urged the Canadian government to press forward with its Net Zero Emissions Accountability Act, Bill C-12, which it said, has been languishing in Parliament. “Carbon pricing is good,” Gage said, “but a strengthened Bill C-12 will ensure that current and future governments keep working to achieve our climate targets.”

AHRI applauds inclusion of HFC reduction language in Omnibus Bill

ARLINGTON, Virginia, 27 December 2020: The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) on December 22 expressed its gratitude to House and Senate negotiators who included language in the just-passed Omnibus bill to bring about a national phasedown of HFC refrigerants. Particular appreciation also is due to Senators John Kennedy (R-La.), Tom Carper (D-Del.) and John Barrasso (R-Wyo.) as well as to Representatives Frank Pallone (D-NJ), Pete Olson (R-Tex.), and Paul Tonko (D-N.Y.) for their tireless efforts to see this bipartisan initiative through to completion, AHRI said.

The language included in the bill would bring about a national phase down of HFCs and allow for a market- and consumer-friendly transition to new and better performing refrigerants and related products and equipment, AHRI said.

“We are gratified that negotiators included this bipartisan, jobs-promoting language in the Omnibus bill, and we are grateful to the Senate and House champions who worked so hard to see it accomplished, and to the House and Senate for passing the bill,” said Stephen Yurek, AHRI President & CEO. “Our industry has been working toward this goal for more than 10 years, and it is very exciting to see our vision of an HFC phasedown reach the home stretch. We are hopeful that President Trump will quickly sign the bill, so we can pivot toward implementation.”

Quoting a 2018 study by Interindustry Forecasting at the University of Maryland (INFORUM), AHRI said an HFC phasedown will create 33,000 new manufacturing jobs, increase direct manufacturing output by USD 12.5 billion, and increase the US share of the global HVACR export market by 25%.
