 Context examples 

Humans only make the problem worse by consuming more fossil fuel-generated energy to run air conditioners.

(Dangers of Concurrent Heat Waves, Air Pollution, The Titi Tudorancea Bulletin)

Refrigerators and air conditioners based on HFCs and HCs are also relatively inefficient.

(Green material for refrigeration identified, University of Cambridge)

The results could be used in the development of highly-efficient solid-state refrigerators and air conditioners, without the need for bulky and expensive magnets.

(Electronic solid could reduce carbon emissions in fridges and air conditioners, University of Cambridge)

The researchers looked at the energy needed to meet cooling needs of populations exposed to heat stress by taking into account climatic conditions, type of housing, access to electricity and ownership of air conditioners.

(Billions at risk from heat stress at home, SciDev.Net)

A promising replacement for the toxic and flammable greenhouse gases that are used in most refrigerators and air conditioners has been identified by researchers from the University of Cambridge.

(Electronic solid could reduce carbon emissions in fridges and air conditioners, University of Cambridge)

The gases currently used in the vast majority of refrigerators and air conditioners —hydrofluorocarbons and hydrocarbons (HFCs and HCs) — are toxic and flammable.

(Green material for refrigeration identified, University of Cambridge)

In addition, the gases currently used in the vast majority of refrigerators and air conditioners are toxic, highly flammable greenhouse gases that only add to the problem of global warming when they leak into the air.
