Bob and Tim are going out to a new job. It’s an air cooled chiller on the rooftop of an office building. This is the first air cooled chiller that Tim has ever seen so Bob is going to have to describe the operation of the chiller to Tim.
Tim read the specifications of the chiller to Bob as they were riding down the road to the job. He said, “This is a 100 ton chiller with 2 reciprocating compressors used for the refrigeration. (Figure 1) It is an air cooled chiller so that means it has multiple fans. It is on the rooftop so we’re going to have to do all service from the ground to the roof. How do we get to the roof”?
