The present paper explores the possibility of replacing the water cooling stream with an ammonia stream in surface condensers. Considering the high enthalpy of phase change of ammonia, if the boiling process of ammonia replaces the water cooling process, then the required cooling for condensation can be provided at a smaller surface area and coolant flow rate. To this end, first, the ammonia flow in one tube of a sample surface condenser is modeled, and the heat transfer equations are solved for different inlet temperatures and flow rates. By repeating the solution with the tube length considered constant, the required inlet flow rate for one tube at different temperatures is obtained. Then, it computes the heat transferred from one tube, and by dividing the total heat needed for condensation of steam by the calculated heat, it obtains a relation for computing the total surface and flow rate required. The investigation results reveal that the ammonia flow rate required is considerably lower than that of water, and also, at low ammonia temperatures, the surface area required will be considerably low.
