21, a DC system allows the air conditioning black e decker and solar energy through direct docking

By the end of 2015 Beijing black e decker house prices will rise 15%
21, a DC system allows the air conditioning black e decker and solar energy through direct docking technology black e decker achievement appraisal, experts believe that this will increase the promotion of PV market drivers, is expected to get rid of dependence on government subsidies. By Gree independent research and development of photovoltaic inverter black e decker direct drive centrifugal day in the outcome of the appraisal meeting of the Guangdong Provincial Science and Technology Department, has been recognized as a leading international expert group unanimously. black e decker Due to the instability of photovoltaic power generation, electric front access to electricity, you need to install the regulator device, which increases the cost of photovoltaic power generation applications, but also reduces the efficiency of electricity use, is one of the factors is difficult to promote the product side of PV. Root introduced and compared to conventional solar air conditioning, this technology eliminates the need for grid-connected inverter, the direct use of solar power, but also in air conditioning can require less or stop, the surplus electricity back to the grid issue, not only reduces investment costs, but also improve the utilization of solar energy by about 6% to 8%. Air conditioning is a true electric tiger, the energy consumption in public buildings, the building air conditioning system energy consumption accounted for more than 50%. Zhuhai Gree staff said to demonstration projects, for example, a 400kw solar inverter centrifuge 4-10 months a year to work, work eight hours a day, solar power 340kw, may be saving 571,200 kwh, according to commercial electricity price of 0.9678 yuan. kwh a year, saving 552,800 yuan. Currently, this technology has been applied in Gree large central air conditioning on. China Refrigeration black e decker and Air Conditioning Industry Association Secretary General Zhang Zhaohui and other experts said the new technology will be the first large-scale solar energy used in central air-conditioning, reducing the user's capital investment and energy consumption from renewable energy utilization point of view to solve the problem of air conditioning energy consumption; currently , including the promotion of renewable energy, including black e decker photovoltaic mainly black e decker rely on government subsidies, new technologies and emerging black e decker new products, increased its market drivers.
