Consider an office room that is being cooled adequately by a 12,000 Btu/h window air conditioner. Now it is decided to convert this room into a computer room by installing several computers, terminals, and printers with a total rated power of 8.4 kW. The facility has several 7000 Btu/h air conditioners in storage that can be installed to meet the additional cooling requirements. Assuming a usage factor of 0.4 (i.e., only 40 percent of the rated power will be consumed at any given time) and additional occupancy of seven people, each generating heat at a rate of 100 W, determine how many of these air conditioners need to be installed to the room.

Question
Consider an office room that is being cooled adequately
by a 12,000 Btu/h window air conditioner. Now it is
decided to convert this room into a computer room by installing
several computers, terminals, and printers with a total
rated power of 8.4 kW. The facility has several 7000 Btu/h
air conditioners in storage that can be installed to meet the
additional cooling requirements. Assuming a usage factor of
0.4 (i.e., only 40 percent of the rated power will be consumed
at any given time) and additional occupancy of seven people,
each generating heat at a rate of 100 W, determine how many
of these air conditioners need to be installed to the room.
