A design in heating and cooling system of centralair-conditioning for Shanghai Bookmall
IntroductionNowadays, with the rapid development of national economy, people's life level has beencontinuously improved,the requirement of indoor environment id getting higher and higher.Both in terms of maintaining comfortable indoor environment and in keeping the quality ofpeople's life, health, safety, and the effect of heating and cooling source system is veryimportant.As the “heart”of refrigeration and air conditioning systems, cooling and heating systemplays a very vital role in system investment and energy consumption. Meanwhile, as themainstay of HVAC industry, refrigeration and air conditioning system of cold and heat sourceequipment is an important content of building energy supply systems. Heating and coolingsource project is to optimize the allocation of heating and cooling system as well as to runefficiently and stably for specified area and building.Topic sourceThe title of this topic is “A design in heating and cooling system of central air-conditioningfor Shanghai bookmall”.The task of this graduation design is required to build heating andcooling air-conditioning system load calculation; Through the analysis of the equipment ofheating and cooling source calculating and selecting ;as well as laying out the equipment andpipes of heating and cooling source room; No less than required engineering drawings in linewith national requirements and complete the design task on time.Design standardsThe construction area is 79,200 m2, with 4 underground floors and on the ground floor by a8-24 layers ranging from three zones, namely the Area A, Area B, C area. The directcombustion engine room and pump room cooling arranged in the ground. The heat sourceproject of air-conditioning system is supplied by direct combustion room in the main buildingon the eastern side of the ground floor, room features a direct-fired three direct-fired absorptionchiller unit, the main heat source to meet the annual demand of all cold water cycle pump, hotwater circulation pumps, and cooling water circulation pumps and other equipment located inthe direct-fired three underground room below the pump room cooling, cooling tower locatedcorresponding region B 14 layers of roof. Design principlesThe actual design of the main requirements of the project conditions and the calculatedload by Hongye HVAC software to select the appropriate heat source equipment. Meanwhileincorporating various types of reference data to choose a variety of devices suitable heat sourcerequired for the engine room and reasonable arrangement on the drawing.
