Question
A manufacturing company is intending to use its
water cooled condenser for its
proposed cold storage room. The name plate of the
condenser gives the following
specifications:
refrigerant ammonia
condenser water inlet 30 OC
condenser water outlet 40 ỌC
condensing temperature 35 OC
refrigerant flow 3.84 kg/min
circulating water flow 120 kg/min
If the company decided to purchase a new
compressor and evaporator, find the tonnage
of the system and the temperature in the
evaporator, (b) what is the COP? (c) find the
theoretical hp required.
