The Chinese producer mentioned that its new photovoltaic air conditioner is out there in three variations with a cooling capability from 12.1 kW to 16 kW and a heating capability of 14 kW to 18 kW. It can be utilized for each residential and business functions.
Chinese air conditioner producer Gree Electric Appliances launched a photovoltaic DC air conditioner for residential and business functions on the SNEC tradeshow in Shanghai, China, this week.
“Our Photovoltaic Multi VRF System might be simply mixed with a number of photo voltaic modules and gives a whole energy era.
system answer,” mentioned a spokesperson from the corporate pv journal. “It will also be utilized in factories, buildings, faculties, accommodations, hospitals, residences, workplace buildings, laboratories, exhibition halls and business complexes.”
According to the producer, the system relies on a multimode commutation know-how that may change between 5 completely different operation modes inside 10 ms: when the air con system just isn’t wanted, the facility generated by the photo voltaic array is injected into the grid; if there may be extra solar energy, the air conditioner is turned on earlier than the grid injection; when PV energy is missing, air conditioners use grid electrical energy; if the PV energy era can meet all of the wants from the air conditioner; and when the PV system just isn’t working, the air conditioner attracts energy from the grid.
The firm claims that the direct drive utilization charge can attain as much as 98%. “Compared to the non-direct-driven system, it saves many AC-DC conversion processes, reduces gear funding, and improves system effectivity by greater than 6%,” added the spokesperson.
The outside unit is out there in three variations with a cooling capability from 12.1 kW to 16 kW and a heating capability of 14 kW to 18 kW. The rated enter energy is from 5.9 kW to 7 kW and the rated present is from 29.8 A and 35.5 A. The PV enter voltage vary is 120-400 V and the utmost PV enter energy is 6 kW.
The system makes use of R140A as refrigerant and has a sound energy stage of 74 dB(A) to 77 dB(A). It measures 900 mm × 340 mm × 1,345 mm and weighs 120 kg. The producer says that the air conditioner will also be mixed with its Gree Intelligent Energy Storage System that integrates vitality storage cells, BMS, and DC/DC.
“It additionally adopts low-voltage DC parts to make sure the protection of the unit, decreasing the hidden dangers of unintentional electrical shocks within the use and upkeep of the unit, in addition to hearth dangers on account of getting old of the wires,” the spokesperson continued to say. “It makes use of membrane capacitors that provide excessive voltage resistance, non-polarity, and the flexibility to face up to excessive ahead and reverse excessive pulse voltages.”
Gree relies in Zhuhai, China, and is the nation’s largest air conditioner producer. It operates factories in China, Brazil and Pakistan.
