Page 35: Air Conditioning The Computer Room
9. Air Conditioning the Computer Room 9-1 Main Features of the Floor-Duct Air Conditioners This system is installed by building a floor over an existing floor and using the space between these two floors as an air-conditioning duct. This system has the following characteristics: 1 The temperature and humidity can efficiently and reliably be controlled, since the air-conditioned air is sent directly to the machine. -

Page 37: Conditions For The Installation Of Computer-Room Air Conditioners
9-4 Conditions for the Installation of Computer-Room Air Conditioners (1) Outdoor Temperature and Humidity Generally the values set for general air conditioners are used, although the value higher than the maxi- mum outdoor temperature and humidity may be set for devices like computer-room air conditioners that must keep the air temperature and humidity under predetermined levels. -
Page 38: Setting The Air Conditioners
9-5 Setting the Air conditioners (1) Air-Conditioning Load 1 Once the floor plan is made and the conditions for the air-conditioning system are set, air conditioning capacity has to be determined by calculating the load. 2 Unlike the outdoor air, computer load remains constant throughout the year. However, it is possible that there are considerable fluctuations within a day. - Page 39 (2-3) Calculating the Load and Selecting a Model Calculate the temperature difference by setting the outdoor temperature; then, calculate hourly loads. The chart shows the result of a calculation, supposing that the system reaches its highest load at 12 o'clock. Outdoor temperatures in this example Summer : 32˚CDB relative humidity 60% Winter : -2˚CDB relative humidity 42%...
