Foreword

Enter, market economy lateral to promote rapidly with China new century, the integration of urban and rural economics of China has obvious quickening trend too, so the building trade has already got fast development. In several in the civil architecture consumes energy, the warm energy-consuming situation of understanding air-conditioning equipment is most serious, its energy of dawdling accounts for and always dawdles more than 40% of energy, this is the most important factor of running cost after influencing the project to be completed too. So, it just becomes a most important difficult problem in front of system engineer of air conditioner that the energy-conservation in the warm open air-conditioning system is designed, and there is important realistic meaning in the fast development of this pair of warm open air-conditioning systems.

1,Design parameter of the warm open air-conditioning system of the reasonable choice

1,Highly energy-consuming case study of the warm open air-conditioning system of the building

At present, the highly energy-consuming problem exists yet in the warm open air-conditioning system of building of China, also there are a lot of unreasonables in the regulation system design of the air conditioner, cold plane and air blower and water pump break away from, order orbit that run while being high-efficient, can’t yet it realizes energy utilization to be high-efficient. The switch in the warm open air-conditioning system of the building is not switched over in time, will cause the waste of the efficiency of the air conditioner too. On the structure thermal insulation of the BLDG, it is unreasonable to because moves towards and enters the deep design and exists a lot the glass structural adoption of curtain wall, this will cause the internal and external districts of the air-conditioning system to be uneven in temperature. Generally influenced by external meteorological factor bigger in the outer zones of the air-conditioning system, need cooling at the temperature, but need heat supply at low temperature. In addition, the water amount unbalance situation in Read more
