Haier Group Corporation, debuted its magnetic bearing centrifugal chiller unit with the largest cooling capacity, 4200RT in world, at the 28th China Refrigeration Exhibit held in Shanghai New International Expo Center on April 12. The newest unit brings the use of magnetic levitation technology in the refrigeration sector to an entirely new degree.
At variance with traditional central air-conditioning, the unit that is maglev consumes 50 per cent less energy is friction and petroleum free and contains a 30-year-long service life, twice as long as conventional units. In terms of becoming among the crucial development directions for the central AC industry, magnetic bearing centrifugal chiller is taking the front seat as a result of these advances. Haier pioneered the development of the magnetic bearing centrifugal chiller sector in China and, in 2015, started its first version which, at that time, was the highest accessible cooling capacity available on the market. A new world record is set by the merely rolled out 4200RT unit. More information: Novelcare from Toronto Ontario
When it comes to brains technology, the unit includes the self-cleaning Driverless maglev system, a method that is fully automated to the idea of requiring no human intervention for upkeep as well as maintenance throughout the whole life cycle, and requires half the power consumption of conventional units when in operation. The air conditioner is the very first unit on the market that uses artificial intelligence to large-scale industrial gear, making complete usage of the latest in technological improvements in terms of the interconnection between man and machine and between machine and machine.
In the Chinese market, 539 magnetic bearing centrifugal chillers have been, to date, assembled and installed by Haier. Based on industry experts, progress are not only represented by the 4200RT unit that is new in invention and magnetic levitation technology applications, but additionally acts as a core contributor to emission decreases and energy conservation, while functioning as a keystone for the transformation of the green building sector.

Within an note that is other that is intriguing, San Diego Gas & Electric’s plan directed at reducing air conditioning usage during the latest days of the summer is going by way of a significant reduction of its own.
"Whenever we've plans which might be created for energy efficiency and which are financed from our customers, we want to make sure they're achieving the things they set out to do ,” said SDG&E spokeswoman Amber Albrecht.
There are still 20,000 SDG&E customers enrolled in the strategy, most of them residential customers. The move marks the first time customers have already been cut from the plan.
Chris Landry, a Scripps Ranch homeowner who has received a yearend credit on her SDG&E invoice that she estimated at $200 to $400, is doubtful about the utility’s motivations.

“We redesigned the plan because we didn’t want to remove (it) because for the majority of consumers who are on it, we are detecting ... load reduction,” said Albrecht.
The Summer Saver Program is just one of a host of what exactly is called “demand-response” plans that utilities offer as incentives for customers to reduce energy consumption when demands on the system are at their maximum.
“ The program was created to take AC units that are running and turn off them at these crucial times,” Albrecht said. “If that AC unit isn’t running there’s nothing ’s no load reduction and there to turn off.”
The size of the credit also depends on how big the air conditioning units, whose one- hour cooling capacity is measured in tonnage. Usually, one short ton will cool a dwelling of 400 to 700 square feet.
SDG&E pays $27 per ton for a customer enrolled at 100 percent and $10.35 per short ton for those registered in the 50 percent plan.
Landry, who lives in a two-story, 3,800-square-foot home and signed up for the 100 percent option, said she liked receiving the end-of-the-year credit so when she received a letter from SDG&E last month telling her she was being removed from the program, “I phoned them instantly,” for an explanation.
After some discussion, Landry was put back onto the plan.
“We’ve been working with each customer separately through our call center to discover what’s the best solution for them,” Albrecht said. Other energy efficiency programs contain a “smart thermostat” plan that allows SDG&E to control the meter on particular days and programmable thermostats.
Instead of dropping folks, “, I believe they should just lower whatever they’re giving us” at the conclusion of the entire year, said Landry.
Albrecht said the review of the Summer Saver Program was done through the “E3 Calculator.
“It’s actually about conserving our customers money all,” Albrecht said. “It’s our occupation to actually value (how) we are spending these dollars. Can it be really resulting because statewide target, what our clients are spending for? Are we seeing the results that are needed seriously to maintain the integrity of the power grid during these crucial times? And otherwise, how do we get there?”
To help the state meet its clean energy goals, California’s utilities have been instructed to match a 5 percent goal for demand-response resources by 2020.
