Haier Group Corporation, debuted its magnetic bearing centrifugal chiller unit with world’s greatest cooling capacity, 4200RT, at the 28th China Refrigeration Exhibit held in Shanghai New International Expo Center. One unit can cool a 100,000-square-meter, a feat unmatched to date, while the Integrated Part Load Value (IPLV), the index of efficiency at full load conditions, measures 13.18. The brand new unit brings the application of magnetic levitation technology in the refrigeration sector to an entirely new level.
At variance with conventional central air-conditioning, the maglev unit is oil and friction free, consumes 50 per cent less energy and has a 30-year-long service life, twice as long as units that are conventional. In terms of becoming among the essential development directions for the central AC business, magnetic bearing centrifugal chiller is taking the front seat as an effect of these advances. Early in 2006, Haier pioneered the development of the magnetic bearing centrifugal chiller sector in China and, in 2015, established its first version, rated at 2200RT, which, at that time, was the maximum accessible cooling capability on the market. The only rolled out 4200RT unit establishes a new world record. More advice: the Novelcare company
In terms of intellect technology, the unit features the self-cleaning Driverless maglev system, a system which is completely automated to the purpose of requiring no human intervention for upkeep and care during the whole life cycle, and requires half the power consumption of conventional units when in operation. The air conditioner is the primary component in the industry that uses artificial intelligence to large-scale industrial equipment, making full usage of the newest in technological improvements when it comes to the interconnection between man and machine and between machine and machine.
In the Chinese market, 539 magnetic bearing centrifugal chillers have been, to date, built and installed by Haier. Based on industry experts, the 4200RT unit that is new not only represents improvements in magnetic levitation technology applications and innovation, but also acts as a core contributor to energy conservation and emission reductions, while serving as a keystone for the transformation of the green building sector.

Within an other note that is intriguing, San Diego Gas & Electric’s plan aimed at reducing air conditioning usage during the hottest days of the summer is going by way of an important decrease of its own.
“Whenever we have programs which might be intended for energy efficiency and which are financed from our customers, we want to make sure they are achieving the things they set out to do ,” said SDG&E spokeswoman Amber Albrecht.
There are 20,000 SDG&E customers enrolled in the plan, 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 year-end credit through the Summer Saver Program on her SDG&E invoice that she estimated at $200 to $400, is skeptical concerning the utility’s motivations.
“I believe the plan is costing them too much,” she said. More facts on Ductless Air Conditioners here, should you like to find out more regarding the science of AC.
But Albrecht said the reduction came after having a cost-benefit review of the Summer Saver Program and was signed off by the California Public Utilities Commission (CPUC).
“We redesigned the program because we didn’t would like to remove (it) because for nearly all customers that are on it, we are seeing … load decrease,” said Albrecht.
The Summer Saver Program is just one of a bunch of what is called “demand-answer” plans that utilities offer as incentives for customers to reduce energy consumption when demands on the system are at their maximum.
“ The software was created to take AC units which are already running and turn them away at these crucial times,” Albrecht said. “If that AC unit isn’t running there’s nothing there and to turn off ’s no load reduction.”
The size of the credit also is dependent upon the size of the air conditioning units, whose one- hour cooling capacity is measured in tonnage. Normally, one ton will cool a residence of 400 to 700 square feet.
SDG&E pays $27 per short ton to get a customer registered at 100 percent and $10.35 per short ton for those registered in the 50 percent plan.
After some dialogue, Landry was put back onto the program.
“We’ve been working through our call center separately with each customer to discover what’s the best alternative for them,” Albrecht said. Other energy efficiency plans contain programmable thermostats and a “smart thermostat” strategy that enables SDG&E to control the meter on specific days.
“Instead of losing individuals, I think they should simply lower whatever they’re giving us” at the conclusion of the year, said Landry.
Albrecht said the report on the Summer Saver Program was done through the “E3 Calculator” used by the CPUC.
“It’s really about conserving all of our customers cash,” Albrecht said. “It’s our job to actually value (how) we’re spending these dollars. Can it be really resulting in that statewide goal, what our clients are spending for? Are we finding the results that are needed seriously to preserve the integrity of the power grid during these critical times? And otherwise, how do we get there?”
To help the state meet with its clean energy targets, California’s utilities have now been instructed to match with a 5 percent target for demand-response resources by 2020. As of mid-2015, the utilities needed another 640 megawatts of demand-response to satisfy the aim.
