The REAL Alternatives 4 LIFE project recently published a set of newly updated material on its e-learning platform. With the aim of addressing climate change and supporting the rapid move to alternatives from high GWP refrigerants...

Many in the HVACR industry seemed a little surprised when the U.S. Court of Appeals for the District of Columbia Circuit recently denied a petition that asked the court to revisit its August 2017 decision, in which it was mandated that the U.S. Environmental Protection Agency (EPA) cannot ban hydrofluorocarbon (HFC) refrigerants under Section 612 of the Clean Air Act.

Many air conditioning and refrigeration systems have their condensing units located outdoors for two main reasons. First, this takes advantage of the cooler outdoor ambient temperatures to reject the heat absorbed in the evaporator section, and second, to reduce noise pollution.

Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start.

The U.S. economy is looking more robust, with many economists predicting the gross domestic product (GDP) will grow between 2.5 and 3 percent this year.

The U.S. Environmental Protection Agency (EPA) cannot require HVACR manufacturers to replace so-called high-global warming potential (GWP) refrigerants with lower GWP replacements.

Daikin America Inc., a wholly-owned subsidiary of Daikin Industries Ltd, has completed the first United States retrofit installation of its new low global-warming potential (GWP) refrigerant, Creard R-407H, in the refrigeration system of a cold storage warehouse. Creard R-407H was used to replace the system’s existing R-22, and this successful conversion demonstrates that this new refrigerant from Daikin is an ideal option for similar conversions from R-22.

California State Sen. Ricardo Lara (D-Bell Gardens) recently introduced the California Cooling Act (Senate Bill 1013), which is designed to reduce the use of hydrofluorocarbons (HFCs), which are considered to be a growing source of greenhouse emissions in California and around the world.

WASHINGTON – U.S. Sens. John Kennedy (R-La.) and Tom Carper (D-Del.) recently introduced a bill, the American Innovation and Manufacturing (AIM) Act, which they state will provide certainty for businesses in the U.S. on the worldwide transition towards next-generation coolants.

Saying goodbye is never easy, whether it’s a relative, friend, or coworker. Last month, I was sad to say goodbye to my dear colleague, Ron Rajecki, who has been the editor of FROSTlines for the last three years. Ron has decided to pursue another “adventure” in the HVAC industry, and he leaves behind some very large shoes to fill.
