Condensing Heat Exchanger

The condensing tank is a constant pressure heat exchanger on the high pressure side of the apparatus in which the high temperature, high pressure freon gas gives up heat to the cooling water and condenses to the liquid phase. The freon leaves the heat exchanger at about the temperature of the inlet water to the tank.

The constant water flow through the tank permits the heat released by freon condensation to be measured. The water flow rate can be measured as can the temperature difference between the inlet and outlet water. From this data, the heat release rate can be determined. The freon flow rate is also known and its heat release can be estimated for the constant pressure heat exchange process.

Apply an energy balance argument to the heat released by the freon and that adsorbed by the water. Do your calculations yield what you expect?
