Abstract
The task is to design the air conditioning system of a puter room in Jinan. The building has four floors, with a total construction area of 3715m2 and meters floor height. The air conditioning area of each layer is 460m2. The purpose of this design is to maintain the constant temperature and humidity of the room air and to keep a certain degree of fresh air volumn, so that the operation puter is safe and stable, and the crew fortable.
In the design, there is a brief introduction about the history and status of air-conditioning for puter room. Through research pare several forms of central air conditioning system, and according to the characteristics of puter room itself, finally the semi-centralized central air conditioning system is selected as the solution. The air supply uses independent fresh air and fan coil units, and the fresh air will be handled to the indoor air state point by the fresh air units and directly sent into the room.
