Technology suppliers made the case for the energy saving potential of CO2 heat pumps in Southeast Asia’s hospitality sector.

Connecticut has joined California, New York and Maryland in announcing its intention to phase out the use of HFC refrigerants.

The Maryland Department of the Environment (MDE) announced yesterday that the state will be pursuing measures to phase out the use of HFCs, closely following a similar announcement by New York Governor Andrew Cuomo on Monday and the passage of the California Cooling Act by the California legislature on August 30.

Honeywell has announced the commercial availability of R452B, the lower GWP “mildly flammable” refrigerant alternative to R410A.

New York Governor Andrew M. Cuomo announced today that he was directing the state’s Department of Environmental Conservation (DEC) to issue regulations phasing out the use of HFCs.

The Spanish government has approved a plan for €1.5m in aid for the conversion or replacement of supermarket refrigeration systems to alternative low GWP refrigerants.

A recent paper argues that multi-ejector CO₂ technology in supermarkets can lead to better performances than HFCs in terms in energy efficiency, even in warm climate locations. As a result, the “CO₂ equator” could be moved south.

Convinced of their status as a market-ready alternative to HFCs, Swiss retailer Migros expects the “vast majority” of its supermarkets to use natural refrigerants by 2030 – most of which will use CO₂ transcritical systems.

As the price of high Global Warming Potential (GWP) refrigerants increases and regulations become tougher, Danfoss is continuing its Refrigerant Week initiative to help industry professionals and decision-makers make the transition to lower-GWP refrigerants. Refrigerant Week, an official affiliate of Climate Week NYC, will take place from September 24th to 28th and feature webinars, tools, resources, and local events aimed at promoting and enabling lower-GWP solutions.

ASHRAE is pleased to announce registration is open for its 2019 Winter Conference, to be held in Atlanta, Ga., Jan. 12–16, at the Omni Hotel Atlanta at CNN Center and the Georgia World Congress Center. Registration for the conference provides entry to the co-sponsored AHR Expo, to be held Jan. 14–16 at the Georgia World Congress Center.

Engie Refrigeration’s air-cooled Quantum chillers can now be equipped with heat recovery, making it possible to reuse up to 100% of the generated waste heat.

Researchers at the Fraunhofer Institute claim to have developed a viable propane heat pump using low volume heat exchangers and a special compressor.

California has voted to pass the California Cooling Act which will restrict the use of high GWP HFC refrigerants and other HFC compounds.

A-Gas has warned customers to beware of offers of cut-price refrigerant as these may be stolen or illegal imports.

Having designed and installed the first NH₃/CO₂ cascade refrigeration systems in the Phiippines, Omnico Engineering Ltd. foresees growing demand for natural refrigerant-based HVAC&R equipment there. This website spoke to Omnico Engineering Managing Director Bjarne Waldstrom about these first installations ahead of the ATMOsphere Asia conference on natural refrigerants, to be held in Singapore next month.

Denmark-based HB Products has recently developed a new ‘zero super-heat control’ vapor quality sensor for CO₂ systems, named HBX-CO2-CU-XX.

The illegal import of refrigerants in disposable cylinders continue with the Baltic states adding to the outcry.

Brandels, a UK manufacturer of cooling products for dispensing alcoholic beverages, launched a new line of beer, cider and wine dispensers using hydrocarbon refrigeration technology.

Viking Cold Solutions, a Houston, Texas-based thermal energy storage (TES) systems manufacturer, reported in a study last week that it was able to reduce both peak energy consumption and peak demand at a California frozen food distribution center by installing one of its systems in the facility’s 93,000-sq-ft low-temperature freezer.

The board of the International Institute of Ammonia Refrigeration (IIAR) has given its approval for the trade group to work with ASHRAE on writing a safety standard for hydrocarbon systems used in commercial and industrial applications.
