Efficiency improvement in aerothermal household heating systems
Abstract: This paper shows a new method to improve the aerothermal household heating system. The development bases the design on a forced convection assistance unit attached to the water radiators used for heating the house. The proposed design applies to any household heating system with wall radiators powered by an aerothermal unit. The household heating protocol is enhanced thanks to a quicker rate of room temperature rising, which allows setting up …

Analysis of Heat Transfer in a Heat Exchanger with Triangular Fins Using Finite Element Modeling
Abstract: The influence of radiation and convection on a catalytic reactor's triangular heat exchanger fins are examined. Heat escapes from the surface by radiation and convection having being transported by conduction throughout the fin. Convection and radiation enable the fin's tip to lose heat, whereas the base of the fin is kept at a constant high temperature. One of the walls is taken for consideration because of its symmetry and ease …

Effect of Different Cooling Pad Materials on the Performance of the Evaporative Cooler
Abstract: Air conditioning (AC) becomes the most necessary appliance in homes and offices in every developed and developing country for achieving the required thermal comfort condition. But the literature reveals that the excessive use of AC creates physiological discomfort such as headache, alleging symptoms (fever, cold, itching) chest pain, etc. The above mention issues may be mitigated up to a certain level by using an evaporative cooler instead of ACs. The …
