Haier Group Corporation, debuted its magnetic bearing centrifugal chiller unit with the largest cooling ability, 4200RT in world, at the 28th China Refrigeration Exhibition held in Shanghai New International Expo Center on April 12. One unit can cool a 100,000-square-meter, a feat unmatched to date, while the Integrated Part Load Value (IPLV), the indicator of efficiency at full load conditions, measures 13.18. The new unit brings the application of magnetic levitation technology in the refrigeration sector to a totally new level.
At variance with conventional central air-conditioning, the unit that is maglev is petroleum and friction uses up 50 per cent less energy and has a 30-year-long service life, twice as long as units that are traditional. As a consequence of the improvements, the front seat is being taken by magnetic bearing centrifugal chiller when it comes to becoming among the key development directions for the central air conditioning sector. Early in 2006, Haier in 2015, started its first model, rated at 2200RT, which, at the time, was the highest accessible cooling capability available on the market and, pioneered the development of the magnetic bearing centrifugal chiller sector in China. The only rolled out 4200RT unit establishes a new world record. More advice: NovelCare company
In terms of intelligence technology, the unit includes the self-cleaning Driverless maglev system, a method that is fully automated to the purpose of requiring no human intervention for upkeep as well as care 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 in the industry that employs artificial intelligence to large scale industrial gear, making full use of the latest in technological improvements in terms of the interconnection between machine and man and between machine and machine.
To date, Haier has, in the Chinese market, assembled and installed 539 magnetic bearing centrifugal chillers. Based on industry experts, the brand new 4200RT unit represents progress in innovation and magnetic levitation technology programs, but additionally functions as a core contributor to emission reductions and energy conservation, while serving as a backbone for the transformation of the green building sector.
Another intriguing way of looking at new era AC technology is through novelcare ac
Within an intriguing note that is other, San Diego Gas & Electric’s program directed at reducing air conditioning usage during the latest days of the summer is going via a significant decrease of its own.
“Whenever we have plans that are made for energy efficiency and which are financed from our customers, we wish to ensure 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 plan, most of them residential customers. The move marks the first time customers have now been cut in 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 doubtful about the utility’s motivations.
“I believe the program is costing them too much,” she said. More facts on Ductless Air Conditioners here if you want to learn more in regards to the science of AC.
But Albrecht said the cut came after a cost-benefit review of the Summer Saver Program and was signed off by the California Public Utilities Commission (CPUC).
“We redesigned the plan because we didn’t want to remove (it) because for the majority of customers who are on it, we’re seeing … load decrease,” said Albrecht.
The Summer Saver Program is one of a number of what is called “demand-response” plans that utilities offer as incentives for customers to lessen energy consumption when demands on the system are at their greatest.
“ The application was made to choose AC units which are already running and turn off them at these critical times,” Albrecht said. “If that AC unit isn’t running there’s nothing to turn off and there’s no load decrease.”
The Summer Saver Program runs from May through October and SDG&E says it won’t cycle the air conditioning more than 60 hours during that six-month span.
The size of the credit also depends upon how big 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 for a customer registered at 100 percent and $10.35 per short ton for those registered in the 50 percent strategy.
Landry, who lives in a two-story, 3,800-square foot house 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 plan, “I phoned them immediately,” for an explanation.
After some dialogue, Landry was put back onto the plan.
“We’ve been working through our call center separately with each customer to discover what’s the best solution for them,” Albrecht said. Other energy efficiency plans contain a “smart thermostat” strategy that allows SDG&E to control the meter on certain days and programmable thermostats.
Instead of dropping people “, I believe they should only lower whatever they’re giving us” at the conclusion of the entire year, said Landry.
Albrecht said the overview of the Summer Saver Program was done through the “E3 Calculator.
“It’s actually about conserving each of our customers cash,” Albrecht said. “It’s our job to actually evaluate (how) we’re spending these dollars. Is it actually resulting for the reason that statewide objective, what our customers are paying for? Are we finding the results which might be needed seriously to maintain the integrity of the power grid during these crucial times? And if not, how do we get there?”
To assist the state meet with its energy targets that were clean, California’s utilities have been instructed to fulfill a 5 percent goal for demand-response resources by 2020. By mid-2015, the utilities needed another 640 megawatts of demand-response to meet the goal.
