The AC is installed with roll bond evaporator, newly designed, tube and fin condenser and rotary compressor. All these three are attached using copper tubes and the refrigerant is supplied which is rotated through this setup. The refrigerant which comes out of the compressor goes into the condenser which is initially at high temperature and then while coming out of the condenser the temperature of the refrigerant is reduced and now it enters the roll bond evaporator through capillary tube in which the low temperature refrigerant is evaporated and then the refrigerant again goes to compressor. The refrigerant used in this project is R-22, tube and fin condenser and 1 ton rotary compressor. Roll bond evaporator, copper tubes, expansion valve are used for assembling of mobile air conditioner and design of AC In the present work, we have attached 6 roll bond evaporators to cool the ups room and connected to throttle valve, compressor condenser with the help of copper tubes. When the AC is switched on the compressor get started and refrigerant enters into compressor condenser. It then enters into the roll bond evaporator and it helps to reduce the room temperature. There are many cell tower rooms in many companies and colleges ups rooms. For best efficiency, life and reliability the temperature needs to be uniformly constant at 23°Celsius. This project also provides a 3D uniform temperature as required by the set point.

This study presents a comprehensive assessment of the hydrodynamic performance of a novel pipe network with tessellated geometry and allometric scales. Numerical simulations were used to evaluate flow behaviour and pressure drop. The comparison geometry featured a Parallel Pipe Pattern (PPP), while the proposed design employed a Rhombic Tessellation Pattern (RTP). Steady-state simulations were conducted under identical boundary conditions, examining water mass flows ranging from 0.01 to 0.06 kg/s. The results revealed RTP significant advantages over the PPP. The RTP, integrated with a fractal tree pattern, demonstrated remarkable capabilities in achieving uniform flow distribution and maintaining laminar flow regimes across the mass flow rates. Additionally, exhibited an average reduction in pressure drop of 92% resulting in improved efficiency. The Reynolds number at PPP inlet was 5.4 times higher than in the RTP, explaining the considerably higher pressure drop. At a mass flow rate of 0.06 kg/s, the PPP experienced a pressure drop of up to 3.43 kPa, while the RTP’s pressure drop was only 0.350 kPa, highlighting a remarkable decrease of 91.5%. These findings underscore the RTP superior performance in minimizing pressure drop, making it suitable for accommodating higher mass flow rates, thus highlighting its exceptional engineering potential.
