When Shanghai’s winter and summer seasons were “electric shortagesâ€, more than 40% of the electricity load was generated using air conditioners. Can we adjust the energy structure, let the air conditioner change the " eating habits", do not "eat" electricity, and turn "eat" natural gas to alleviate the voltage power of Shencheng?
It is reported that an air conditioner driven by "gas engine heat pump" has been successfully developed by Shanghai Jiaotong University. This prototype of "natural gas air conditioner" with completely independent intellectual property rights has passed the acceptance test. According to the plan of the Urban Council, at least 150 such air-conditioned air conditioners will be promoted throughout the city this year.
According to reports, although some manufacturers at home and abroad have designed direct-fired air conditioners, they have low efficiency. When they input 1 part of natural gas, they can only produce 0.8 parts of energy, and the "block" is large, which can only be used in super-large public places. The natural gas air conditioner developed by Prof. Huang Zhen and Associate Professor Gu Anzhong, vice president of Jiaotong University, is a natural gas-fueled internal combustion engine to drive the heat pump system. The 1 kcal gas can generate up to 1.9 kW of energy. Extremely high.
The internal machine of this prototype placed at Jiaotong University is the same as the ordinary air conditioner. The outer machine composed of the engine and the heat pump is an iron box 2 meters high and 1 meter wide. Professor Huang Zhen introduced that this 20 kW air conditioner can meet the housing needs of more than 600 square meters. In the summer, it is easy to reduce the indoor temperature from 38 ° C to 25 ° C. In winter, it can easily increase the temperature from -2 ° C to 28 ° C. The greater the temperature difference, the more efficient it will be.
Natural gas air conditioning not only saves money, but also protects the environment.
Huang Zhen calculated the account, the same use time, natural gas-driven heat pump saves 23% of energy than electric heat pump, the electricity price and gas price ratio, the cost can save 13% to 20%; a 1 million kcal / hour of gas Compared with an electric air conditioner, air conditioning has twice the cooling capacity and can reduce the sulfur dioxide emissions by 16 tons per year. In addition, the air conditioner can be started under normal pressure, the pressure on the pipe network is not high, and the natural gas pipeline of the citizen has begun to take shape. The natural gas of the West-East Gas Pipeline and the natural gas of the East China Sea have been passed into the homes of ordinary people, so it is special. It is suitable for villas, primary schools, shops, restaurants, cinemas and other places with actual use area ranging from several hundred square meters to thousands of square meters.
According to statistics, Shanghai's highest power load in the summer of 2003 reached 13.616 million kilowatts. Last year, this figure reached more than 15 million kilowatts, of which more than 45% of the electricity load came from electric air conditioners, and the proportion in winter also exceeded 40%. If you switch to natural gas to drive air conditioners, it will greatly ease the pressure on Shencheng's power shortage.
It is understood that the Shanghai Municipal Government has planned to add 150 to 180 such air conditioners in the city during the year. If the progress is fast, it will be used this summer.
