Design of Central Air Conditioning System for Organ Hostel in Changsha
Abstract: The design for an organ hostel Changsha central air conditioning system designed to meet summer cooling and winter heating requirements, providing a comfortable working environment for the staff room. The hostel building with a total area of approximately 336056.8m2, the total height of 20.5m. The guest house a total of six, with a restaurant and rooms based. Design includes: air-conditioning cooling load calculation; determine the pision of air conditioning systems and system solutions; choice of hot and cold sources; air terminal handling equipment selection; design and calculation of wind systems; indoor air supply and air distribution in the form of selected; design water systems, layout and hydraulic calculations; design duct systems and plumbing systems of insulation; muffler vibration-proof design and so on. The basis for design specifications to consider energy efficiency and comfort requirements, the use of air-conditioning fan coil system design - the new air system program, and each choice of a new air unit.
