Startup seeks to make energy-hogging air conditioners obsolete

A small clean-technology startup is aiming to rid the world of the rising climatic impression of air-con with a brand new method that it claims can cut back peak power demand by greater than 80% and greenhouse fuel emissions by 85%.

Parkland, Florida-based Blue Frontier LLC’s know-how, which is presently testing its merchandise at nationwide labs and in discipline trials, makes use of a mixture of a concentrated salt answer and proprietary warmth alternate know-how to take away moisture from the air and funky it. The corporate hopes to make a serious dent in one of many world’s largest shoppers of electrical energy.

Vitality hog

Air-con is an environmental dangerous boy on a few fronts. It accounts for practically 20% of power use in buildings, in line with the Worldwide Vitality Company. Because the world grows hotter, demand is anticipated to greater than triple by 2050, “consuming as a lot electrical energy as all of China and India immediately,” the company wrote.

The timing of air-con’s electrical energy use can also be unlucky; peak demand sometimes comes between 3 and 9 p.m.. That’s when the availability of photo voltaic power is low and capability should come from fossil fuel-burning sources.

“It tends to attract a whole lot of energy throughout very inconvenient intervals,” mentioned Daniel Betts, Blue Frontier’s founder and chief govt. “{The electrical} grid is sized for the height electrical load. Within the U.S., air-con makes up about 36% of most peak load however on the most popular days it may be greater than 70%.”

Most air conditioners additionally use hydrofluorocarbon refrigerants which are between 1,000 and three,000 occasions stronger than carbon dioxide as a greenhouse fuel.

Altogether, the World Financial Discussion board estimates that direct and oblique emissions from room air conditioners alone might contribute to a rise in world temperatures of as a lot as half a level centigrade by 2100.

“We sort out each single one of many issues of present air-con know-how,” Betts mentioned. “We make the consumption of power in line with renewable power technology, we enhance effectivity, and don’t use dangerous refrigerants.”

Buying and selling refrigerants for salt

Blue Frontier’s know-how is an alternative choice to refrigerant-based approaches which were used for practically a century. Standard air-con techniques depend on altering the stress of the refrigerant to make it chilly. Blue Frontier as an alternative employs a concentrated salt water answer to take away humidity from the air and makes use of the extracted water as a coolant, Betts defined.

“Salt options are very hygroscopic,” he mentioned. “They wish to be in an answer with water, that means they take up water from the ambiance.”

The patented two-stage system evaporates a portion of the water from the salt answer, thereby rising its focus. Like a squeezed-out sponge, the concentrated salt answer can then take up and retailer water from the air. About half of the work air conditioners do is dehumidification, so the primary stage within the course of robotically makes the air extra comfy. The second stage makes use of an oblique evaporative cooling course of that reduces the air temperature with out rising its humidity.

Because the course of dehumidifies first after which cools, Blue Frontier’s air conditioner can management indoor air temperature and humidity independently of one another, which typical air conditioners can’t. That permits for a wider vary of consolation circumstances that may be regularly tailored to the wants of the constructing and its occupants, Betts mentioned.


The corporate claims its know-how is 3 times extra environment friendly than a standard system, doesn’t use ozone-destroying refrigerants and operates intelligently when renewable power is plentiful within the grid. Through the intervals of highest warmth within the late afternoon and night it runs on low-cost storage that gives about six to eight hours of operation with minimal electrical energy consumption, thus eradicating the load from {the electrical} grid.

Blue Frontier is concentrating on the marketplace for five-ton industrial air-con models, that are probably the most offered air conditioners in U.S. industrial buildings. Betts estimated the potential market to be $800 billion, because the system not solely displaces present air-con know-how but in addition considerably reduces the fee to implement power storage and renewable power infrastructure.

It plans to launch its first models in 2023 however gained’t promote them to clients. Slightly it’s going to personal and function the models and promote the cool air as a service.

“We foresee that at quantity, the manufacturing price of our unit is akin to a standard air-con unit,” he mentioned. “The financial savings are so huge in comparison with a standard unit that we are able to leverage these financial savings to create an as-a-service mannequin.”

Thus far, the corporate has raised greater than $5 million in nondilutive funding and $1.8 million in enterprise funding and plans to hunt a $10 million spherical subsequent 12 months. In October, it was named the startup with probably the most potential to sort out the local weather disaster by the VERGE 21 Speed up Awards. The corporate was additionally listed as one of many Most Fundable Firms by Pepperdine College’s Graziadio Enterprise College.

“The Worldwide Vitality Company has declared that air-con is the largest blind spot in our combat in opposition to local weather change,” Betts mentioned. “As temperatures enhance globally, we are able to make air-con a part of the answer moderately than one of many largest components of the issue.”
