The investigational research to examine the performance of the air conditioning cycle with different capillary tube geometries is discussed in this work. The effectiveness of a VCR cycle is significantly influenced by the capillary tube selection. It is necessary to analyze a basic VCR cycle capillary tube in order to understand the components it could enhance the cycle’s overall efficiency. Within an investigation that was testing using R32 refrigerant, two distinct configurations of 2000 mm long capillary tubes, namely helical and straight capillary, are investigated. The diameter of each capillary tube is kept constant at 2 mm. The objective of the research is to determine how the tube configuration impacts the total system execution of the AC cycle. The outcomes of the study conducted through experimentation revealed multiple significant results: First, the coiled structure has a 5.2% higher refrigeration effect for R32 than the straight capillary; second, the helical arrangement possesses the greatest coefficient of performance (COP), with an amount of 3.72, contrasting with the SC tube configuration with the identical rate of refrigerant flow. Variations in tube design, such as helical tube diameter, can affect how a VCR cycle performs. These significant findings apply to a straight capillary that is refitted with a 120 mm helical coil diameter.
