Thermal Analysis of AC Condenser Coil

Abstract

A refrigeration and air conditioning engineer works on commercial, residential, public and industrial projects, including transportation and storage. Refrigeration is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir. The work of heat transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism, electricity, laser, or other means. Refrigeration has many applications, including, but not limited to: household refrigerators, industrial freezers, cryogenics, and air conditioning.

In systems involving heat transfer, a condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing, the latent heat is given up by the substance and transferred to the surrounding environment. Condensers can be made according to numerous designs, and come in many sizes ranging from rather small (hand-held) to very large (industrial-scale units used in plant processes).

In this project we will design condenser tubes with proper dimensions. The material of tubes is made up of copper and fins are varying with different materials like Aluminum 1100 and Aluminum 1050.The refrigerants varied will be R 12, R 22 and R134. The refrigerants are   Heat transfer analysis done on condenser by using ANSYS CFD (Fluent) and modeling of the condenser tubes is done in SOLIDWORKS.  CFD Fluent is used for to determine the heat transfer rate, temperature and velocity of refrigerant flow.
