China Gas Information
Power air conditioning a mainframe energy efficiency of about 1.3 (a energy efficiency for the actual system for heat and system for energy consumption ratio), and gas air conditioner a energy efficiency can be reached 1.7. Therefore, to speed up the development speed of the gas air conditioner is the future energy utilization direction, the gas air conditioning is to solve the electricity crisis, electricity and gas energy balance one of the options.
In Europe, the fuel gas air conditioning has become the first choice users. Japan, South Korea gas air conditioning market share in excess of 85%. In China, Beijing, Shanghai and guangzhou city gas central air conditioning in the central air conditioning market share in excess of 30%.
Use the most significant advantage of fuel gas air conditioning is environmental protection. Natural gas is recognized as the green energy. The same calorific value of natural gas and coal, natural gas in the flue gas than particles is 1/600 of the coal, sulfur dioxide, coal, 1/120 of the carbon monoxide is 1/130 of the carbon dioxide, coal insufficient two-thirds of coal. So, comprehensive comparison, if the power of air conditioning pollution index as 1, so the air conditioning, natural gas pollution index is only 0.05.
Our country now more than 80% of its electricity from coal-fired power. In coal-fired power conversion efficiency is about 30% of the cases, the price of electricity for huge, about 70% of the energy to a waste.
In addition, the fuel gas air conditioning water refrigerants, water is used in high vacuum state to the characteristics of low boiling point, in the evaporator and absorb heat boiling in, thus making use of air conditioning freezing water. Use of lithium bromide absorption, as agent after boiling water evaporation indoor away, then used repeatedly. So continuously circulation, and completely free of LvFuTing alternatives. And of avirulent, harmless to human body, will not harm the atmosphere, and can reduce the ozone layer 3% to 50% of the greenhouse gas emissions. To protect the ozone layer, the refrigerant reduce because of the greenhouse effect and bring to have the important meaning.
