Abstract:

As well known, a vapor compression refrigeration cycle is a closed cycle consisting of a compressor, a condenser, an expansion valve and an evaporator. The performance of the cooling system is significantly dependent on the condenser. The aim of this study is to conduct heat transfer tests on the compact condensers of built-in refrigerators and to propose improvement suggestions according to the test results. In the introduction section, information is given about the type of condenser used in built-in refrigerators and the parameters affecting the heat transfer. In the material and methods section, the selected coil type condenser and the constraints on the component where it is mounted are explained. Explanatory information about the experimental setup to be used can also be found in this section. In the results section, the results of the experiments on the coil condenser are given. The test results in the discussion section were examined and suggestions were made to increase the performance of the condenser on the refrigerator. The results show that the heat transfer capacity, which is an important parameter determining the condenser performance, and the pulldown temperature are directly related to the condenser surface. It can also be concluded that even if the condenser thermal capacity is sufficient, the pulldown temperature should also be taken into account. Although the thermal capacity of the coil condenser meets the requirements, it is observed that the pulldown temperature is not at the desired values.
