上海大的空调系统设计+CAD图纸(3)
Hall: dry bulb temperature of 26 degrees Celsius in summer, winter dry bulb temperature is 20 degrees Celsius, for fresh air volume after 30 m^3/h * p.
Rooms: dry bulb temperature of 26 degrees Celsius in summer, winter dry bulb temperature is 20 degrees Celsius, for fresh air volume after 60 m^3/h * p.
Big hotel is the main practical and economical on principle. In combination with its own situation, does not need to match with large precision air conditioning system, in accordance with the principle of the design of the comfort air conditioning.
At the tower is a budget hotel accommodation, economical, practical and convenient. According to Shanghai meteorological conditions, and air conditioning design set the basic scheme of the design specification, etc. This design using the fan-coil unit plus fresh air system of air conditioning, each layer has a fresh air units, each layer can use the current fan to conveying fresh air, fan coil units mainly bear indoor hot and cold load. Air conditioning system of water system with double control program system.
Through the initial load calculated the total cooling load of the hotel (including air) at about 500.83 kw, total moisture load (including air) at about 288.732 kg/h. Subsequent equipment selection as well as the subsequent calculations will take place on the premise of this argument.
