Objectives: In this paper, the analyses of Vertical and Horizontal Buried Tube Air conditioning system have been done. The dimensions for optimum performance from the CFD simulation are found. The comparison of the performance of vertical and horizontal Buried tube heat Exchange air conditioning system is included. Methods/Statistical Analysis: CFD simulations were carried out for optimised dimensions of Buried Tube Air conditioning system. In second part of this paper, researcher presented the installation of actual horizontal and vertical Buried Tube Air conditioning system with the help of simulation results at specific region of Gujarat, India. Horizontal buried tube heat exchanger requires more installation area with dry soil. Vertical buried tube heat exchanger is installed from the analysis of simulation results. Pipes of specific diameter and thickness were buried in bore with special type of arrangement. Findings: Horizontal buried tube heat exchanger comprises of horizontal pipe of 0.104 m inner diameter with buried Length of 25 m, made up of RCC and buried at a depth of 3 m in a flat land whereas Vertical buried tube heat exchanger with 110mm diameter and 6mm thickness were buried in the bore of 610mm diameter and 8m depth with special type of arrangement. In the end researcher represented the actual results in context of performance, comparison of simulating and actual results with suggested best the design and loop of heat exchanger for optimum performance. The results also present the dimensions of Buried tube air conditioning system for producing optimum human comfortable condition. The accuracy of this Experimental setup has been verified by comparisons of temperatures of the air and soil and the performance between simulation results with the test data. Applications/Improvements: Vertical and Horizontal Buried tube heat exchanger are used as Buried tube air conditioning system. It can be used for cooling purpose in summer and for heating purpose in winter. It is also useful to handle the green house thermal loads.
