Our office has been rather hot today. Even though the aircon is on full blast, it is ineffective. Why? because the PCs on our desks and computer monitors are radiating heat. In fact, PCs have a fan to expel the hot air from inside the case straight into the office. The PC generates hot air, because the chips it uses run hot, and a fan is used to cool them down, by blowing the warm air straight into the office. Desks are placed back to back, and the hot air radiates back to the user. So we need to pump up the air conditioning. It all seems grossly energy inefficient.
