this case it has been interfered with, the results will be a reduction in the performance efficiency of the heat exchanger which in turn decreases the performance and increases the pressure drop. However, the formation of the deposits is affected by several factors such as temperature, the nature of water composition, and also the speed in which the fluids are moving in and out of the condenser. Normally, higher temperatures, reduced speed of flow of the fluid contributes greatly to the formation of the deposits. This is because as temperature increases, the degree in which calcium carbonate dissolves greatly reduces hence the formation of deposits becomes easy unlike when the temperatures are low (Nitsche & Gbadamosi, 2016).
HEAT TRANSMISSION 3 In estimating the loss in performance within the heat transfer between cooling water flowing inside condenser tubes and refrigerant gas outside tubes we start by calculating the chiller capacity which refers to cooling nature of the heat exchanger system and is calculated as shown below. Chiller capacity= (rate of liquid flow) x chilled water temperature change(T)x specific heat capacity of water (4.186kJ/Kg/ o C) Water temperature change (T) = temperature of the leaving water – temperature of the entering water Since deposition of calcium carbonate reduces performance efficiency, it is, therefore, possible to estimate the overall heat transmitted which is normally referred to as the heat duty which is
