A chiller is providing 5 tons of cooling to an air handler by cooling water transfer between the two devices. The chiller is drawing 3.5 kw of electrical power during this operation. At what rate must the chiller dump energy to the environment (say to a cooling tower) in Btu/hr to satisfy the first law of thermodynamics for that device? Notice that the cooling tower is rejecting not only the energy removed from the cooled space but also the energy input to the chiller.
