A tropical air conditioning system bypasses the air conditioning systems to provide a cleaner air quality and lower CO2 emissions in an outdoor environment, according to a study by a leading US air pollution research group.
Calico Air conditioning, which operates more than 100 outlets in California, is among the biggest suppliers of air conditioning to cities across the US, but a growing number of people have reported problems with the equipment, including problems with cooling their homes and cooling buildings.
In a study of more than 300 people who had experienced problems with air conditioning in their homes, researchers found that those with the highest concentrations of CO2 in the air had the lowest rates of improvement in their CO2 levels, and that those who had been exposed to the lowest levels of CO02 had the best improvement.
“The results suggest that air conditioning is not a safe alternative to air conditioning,” said the lead author of the study, Dr Christopher Ostermeier.
“A high-quality air conditioning unit that reduces CO2 by cooling the building and its occupants will reduce indoor air pollution,” Dr Ostermeisters co-author, Professor Brian Levett, from the University of Wisconsin, said in a statement.
“It’s important to note that we did not find any correlation between the air conditioner’s effectiveness and the amount of COX-2 released in the atmosphere,” Dr Levets team said.
“We therefore concluded that the results do not support the claim that air conditioners have air quality benefits.”
Dr Ostermenes research found that people with higher levels of air pollution were more likely to experience air quality problems, including more frequent cooling failures and increased exposure to CO2.
The findings were published on Monday in the journal Environmental Science & Technology.
Caleco is one of the largest air conditioning companies in the US.
It is the third largest company in the world behind the UK-based Southern Power and the US-based HFC Energy.
The company says it has a “well-established and long-term commitment to providing high-performance, reliable air conditioning and air conditioning cooling solutions to customers across the country”.
The company has also launched a pilot project to test the effectiveness of its equipment on residential buildings and has been selling equipment to businesses for years.
It is not clear whether the air quality issues are related to the company’s CO2-reducing products.
Dr Oestermeier said the findings suggest that “the CO2 system’s effectiveness in reducing CO2 does not necessarily translate to increased air quality”.
The findings come after California Governor Jerry Brown ordered an investigation into whether Calico has broken state pollution laws.
The investigation has been taking place since 2015, but the company says the investigation has not revealed any evidence of illegal conduct.
