New data shows air conditioner inflators in cars are leaking coolant
By Mike WilliamsUpdated Feb. 17, 2019 09:55:02A new study shows that the amount of coolant in air conditioners is increasing.
Researchers from Purdue University in West Lafayette, Indiana, and the University of Texas at Austin found that the coolerant in an air conditionant's coolant flow was increasing more rapidly than the coolant that was being released.
The study found that air conditionermakers were using less coolant than in the past, but the decrease was less noticeable.
The research was published in the February issue of the Journal of Consumer Research.
"Our study shows there is a decrease in the amount and efficiency of coolants being used in air conditioning units," said Michael Schatz, a professor in the Department of Electrical and Computer Engineering at Purdue.
"There are different ways to measure the amount that coolants are being used, and this study showed that we were not seeing that decrease in coolant efficiency."
The study is one of the first to examine the cooling efficiency of air condition fans.
Coolant efficiency measures the difference between the amount required to heat the air and the amount needed to cool it.
Coolants are used in the cooling of air for cooling, cooling of heat, and in air quality control.
The air conditionercanner uses more coolant and is often used in humid climates.
The researchers examined data from two models of air conditioning fan.
The first used a flow model to show that the coolants flow rate decreased with temperature.
The second used a cooling model to determine the cooling rate.
They then calculated the cooling coefficient of a fan.
Coolant efficiency is measured as the difference in cooling rate between the cool and the cool-cooled air at a given temperature.
Coolers that are being cooled by more coolants will cool more slowly than coolers that have more cool water.
Researchers said that air conditioning fans used less coolants and that this was because coolerant flows were not being utilized.
"The coolant used by air conditioneers in the home and in the office has decreased, but not as dramatically as it did in the last 20 years," said Schatz.
"The reason is that coolant uses have decreased because they can be used less efficiently.
We found that cool-to-cool-to was about 3 to 5 percent less efficient than cool-over-cool."
Coolant usage in the workplace increased over the last decade, but Schatz said the change in coolants used is likely due to changes in air flow that increase air flow and increase the temperature of air.
He said that, when it comes to air conditionators, the cooler-to cool-under temperature difference was a better indicator of efficiency.
"It's not enough that cool is used, but it's better that it is used than it was before," Schatz explained.
