Experimental study of condenser material in the air conditioning system

In the air conditioning machine, condenser is considered to be the important component. The present study illustrates the condenser's performance with relevant experiments. The role of a condenser is to release the observed heat from the cooling system because the energy is removed out and the condensed air get drained out and proceeds with its path through the presence of the expansion valve. This present study literally focuses on the external fins and the condenser tubes through the heat transfer mode by the process of forced convection. The temperature changes were calculated for both air temperature system and refrigerator system and appropriate analysis was performed for evaluating the performance of the condenser. The dimensions of the fins, shape and tubing arrangements are also analyzed. The principle of a condenser is to expel the heat out of the refrigeration system by the condensation of vapor. Generally, there is no phase change occurring in the external fluids. In the condenser operated with forced convection mode, the circulated air over the specific surface is maintained with the help of a blower for effective heat transfer. The heat rejection from the condenser is theoretically calculated from the standard value of the compression cycles, without the considering the addition of heat supplied by the compressor inefficiency. The fluid flow of the refrigerant is assisted by the external gravity and hence the inlet tube is aligned at the top whereas the outlet tube is aligned at the bottom. The concept of pipe rising is excluded from the design and extensive care is taken for the adjustment of pipe levels during installation process. Horizontal or vertical air flow is commonly preferred. In the attempt of comparison with various tubes of different diameters, it is considered to focus on smaller tubes with varying diameters to match with the internal surface area of a larger segmental tube.
