During this year's heating season, hundreds of thousands of peasant families in Beijing will use "coal to electricity" and use Tsinghua Tongfang's low-temperature air source heat pump to heat the buildings. Heat pump technology to clean energy-saving, independent household, safe and easy to control features, a vast space for application and huge energy-saving emission reduction role. The picture shows the same side artificial environment engineer Han Linjun is debugging equipment. Zhuang Yuanping photo Late autumn in Beijing, near freezing at night. The weather forecast shows that the minimum temperature next Monday will drop to -3 ℃. Although the city's heating unit has been ready by the end of October, ready to meet the upcoming 2016 heating season; but the harsh environmental situation, Beijing has to face the dilemma of early heating. Coal, thermal power, winter heating, is the main source of air pollution in the northern region. In recent years, in order to practice energy-saving and emission reduction, Beijing is demanding more and more stringent requirements for starting early-stage heating: after several rounds of collective business negotiations, the average daily temperature of less than 5 ° C for five days in a row will heating be possible in advance. In the coming week, Beijing is expected to have two cold air activities. Because of the cold air control for a long time, coupled with unfavorable conditions of diffusion, cold fog days may come back. Clean energy, independent household, safe and easy-to-control heating, a resident of "good heart." South guy's "Kennedy nostalgia" Han Linjun was born in Zhejiang Province is a typical "80" after the science and technology male, but occasionally the tone of young artists. After he was admitted to Tsinghua University in 2003, he has been studying and working in Beijing and now has a Ph.D. Memories of hometown, he said: "No literary author of crisp spring, beautiful autumn ... ... hot summer, cold winter, become my most nostalgic nostalgia." It is such an experience, prompting Han Linjun determined to learn HVAC professionals, research cooling heat pump equipment, from Tsinghua University undergraduate, all the way to save our school master's and doctoral students. After graduation in 2014, Han Linjun choose first-line manufacturing, access to the same side of Human Environment Co., Ltd., engaged in air source, water source heat pump research and development and energy optimization. "Any object including air, water, etc., as long as the temperature is higher than absolute zero, that is -273.15 ℃, it contains heat." Han Linjun opened with popular science, he introduced the heat pump is able to heat objects from low temperature objects to high temperature devices , Similar to the pump, through the consumption of electricity, to achieve water from low to high transmission. "In most parts of our country, the winter outdoor temperature is higher than -20 ℃, the heat in the air is not low, and the heat pump can absorb the heat from the air to the indoor heating," said Han Linjun. He explained that domestic air conditioning is the most common electric pump device. In summer, the air conditioners heat the indoor air to the outside, and the indoor air is cooled down at room temperature. In winter, through internal switching, the function of the air conditioner is to absorb the heat in the outdoor air and send it to the room. At this time, the indoor unit sends the hot air and the outdoor unit emits the cold air. "Compared to normal electric heaters, the heat pump is more energy-efficient and it consumes 1 electric energy per unit, absorbing 2, 3, or even more heat from the air or water." Han Linjun said that the electric pump , Is to take heat from the air, to the water, hot water to the room through the radiator, very comfortable, and no fan noise. In the southern area without central heating, the heat pump technology has a wider application space and can play a greater role in energy saving and emission reduction due to its features of clean energy saving, independent household and safe and easy control.
