Sweating A.C.

They have installed new types of air conditioners in our renovated department. There is a central plant from where they circulate very cold water through copper pipes. For smaller places like lecture halls and offices, they have put split A.C. units on the walls, which are said to consume very little electricity. For bigger places like operation theaters and wards, they have installed air handling units. The thing i said to consume less electricity, though I cannot imagine how. If we go by simple physics, the degree of cooling required will consume that much energy no matter what. Perhaps it is new quantum physics that ordinary people do not understand. But the copper tubes sweat. If the air conditioner is put off, water drips from the tubes and collects on whatever is underneath. They told us to keep the air conditioners on permanently to avoid sweating, whether the rooms are occupied or not. It is true that the tubes do not sweat when the machines are on at all times. But the solution seems very costly. The nurse of the ward above the operation theater complains that the floor exudes water and the ward gets flooded. We had to put stones under cupboards and locker units, so that they would not rust. The contractor checked the drainage, which was OK. Now he says it is the sweating of the air conditioner. I wonder why such a thing has to happen only in our hospital and in my ward. The architect seems to be stumped, since no solution is offered by him despite multiple calls. I could always Google this to find a solution, but so can he, and he is unlikely to accept my solution anyway, if his behavior in past is any indicator of his current and future behavior. So all I can do is wait and hope for the best.
