Perhaps what we have here is a matter of semantics. When a performance test is done at the factory the paperwork doesn't show that the condenser was producing more tonnage than the evaporator. You work for JCI. If you have attended one of their centrifugal classes the two formulas are presented. When one is on a job trying to diagnose a problem the two different divisors (24 for evaporator and 30 for condenser) are used. How else is one to determine if the condenser and evaporator are doing the same amount of work? Using 24 as the constant for both sides will only lead to confusion. We know the condenser has to do more "work" to overcome the heat of compression. If one uses the same constant for both, then they are going to have to do the math to determine if the condenser is rejecting the same heat as the evaporator, hence the reason for the constant of "30" for the condenser. The math is already done.this is for evaporator AND condenser water flows. the tonnage calculation doesn't care whether it is evaporator or condenser and it doesn't know the difference anyway.
Every reference I have found talks about the two different constants. Here's oneand another. ARI standard 550/590-98 says the same. But I guess in the end, we're all going to believe what we want to believe.
