Broad Air Conditioning Zhang Xiaodong: The leader of non

Great many years ago on the foreseeable air conditioning industry, electric air conditioning gas air conditioning replacement trend, so the first start in the domestic non-electric air conditioning. Today, this choice is undoubtedly wise, it also allows us to see Air Conditioning and Shining Path.

ambitious "Never produce electric air conditioning", rather than electric air conditioning have long been a great reputation. Provinces and cities in China in recent years, power cuts, we had to secretly admire the lofty vision. At present, the great mainframes have been sold to more than 40 countries, in the Chinese market share of over 50%, with more than 10 000 users of non-electric air conditioning. Many countries in Europe and the United States market share in the first, up to 90%, has been the world's multinational corporations and government organizations, the product of choice. Recently, the reporter on issues related to non-electric air conditioning on Zhang Xiaodong, deputy general manager of Broad Air Conditioning Co., Ltd had an exclusive interview.

Broad makes electric air conditioning

"China Science and Technology of wealth": Great Why only do non-electric air conditioning, never do anything electric air conditioning? Great significance to promote non-electric air conditioning where?

Zhang Xiaodong: This is from our corporate values. Broad coverage is a color with the values of products, services and management companies. Social transformation in China, the era of non-blurred, great has been insisted on "Seven noes," that does not pollute the environment, technology is not plagiarism, do not deceive customers, not cut-throat competition and avoid debt default, not tax evasion, not bribery, no unconscionable conduct. This is our principle of doing business or is the bottom line.

In the non-electric air conditioning, great stick along the road of specialization, only their own good at something unique in China, a direct-fired air-conditioning, power exhaust in the world's first air-conditioning, developed the world's only double-effect solar air-conditioning the world's largest non-electric air conditioner.

Course, the promotion of non-electric air conditioning is also out of environmental protection and rational use of energy considerations. Great for the tens of thousands of building blocks to provide air conditioning, waste heat from air conditioning, solar air conditioning and other non-electric air conditioning, saving 70 billion yuan for national investment in the construction of dozens of small power stations, to avoid power cuts losses 15 billion yuan. In addition, the great world more than 40 countries provide green services, not only great products are exported to international, but also to penetrate the lofty philosophy of environmental protection wherever we in the United States, France, Spain, Malaysia and other countries have made good results. Ambitious energy consumption survey data show that thousands of customers, great products than 1-4 times more energy-saving international counterparts. Over the years, great products for the global reduction of 10 million tons CO2, 30 SO2 emissions, saving four million tons of standard oil for use in thousands of square kilometers of vegetation to prevent desertification.

"China Science and Technology of wealth": we say that the non-electric air conditioning gas air-conditioned? Non-electric air conditioning is only natural gas for energy?

Zhang Xiaodong: The construction market in the present, the air conditioning on the classification of primary energy into electricity from the air-conditioned and non-electric air conditioning. Electric air conditioning is a type of material as the refrigerant Freon, to mechanical compression acting. We are talking gas air conditioning is lithium bromide as the refrigerant, to absorb the heat acting. Gas Air Conditioner While ambitious strategic layout and non-electric air conditioning accounts for a major share of the market, but it is not all. Non-electric air conditioning also includes as solar energy, waste heat power generation, power generation and gas, biogas, liquefied petroleum gas and other energy air-conditioning, heating energy as long as they can be great can be used for non-electric air conditioning.

"China Science and Technology of wealth": Air Conditioning and Core Technology?

Zhang Xiaodong: Gas air conditioning products is the key vacuum. Great all around it to the technology is carried out.

Cooled by liquid evaporation principle is to obtain heat from the surrounding, is like throwing in the hands of an alcoholic will feel cool, because alcohol absorbs the body heat and evaporation. Evaporative cooling devices used are based on the principle of design than heat. Under normal conditions of atmospheric pressure (760 mm Hg), the water was boiling to evaporate to 100 , but the manufacturer in sealed containers 6 mm Hg of vacuum, then the boiling point of water is only 4 . LiBr solution can create this vacuum, because the lithium bromide (LiBr) salt is a highly absorbent material that can continuously absorb water vapor will come around to maintain the container in the vacuum. It is the use of direct gas fired lithium bromide as absorbent, water as refrigerant, natural gas, diesel and other fuels for heating concentrated source of energy.

But refrigeration technology to ensure a vacuum. If there is no vacuum, it can not guarantee the water evaporated at 4 , the water can not evaporate, the temperature will not drop down, no way to refrigeration.
