Abstract: Most experimental studies have been performed to investigate the fire resistance of a single member, beam, column, wall, and slab. However, a limited number of experimental studies have been performed on full-scale structures, especially reinforced concrete (RC) structures. This paper aims at investigating temperature distribution on a full-scale RC structure under fire. RC structure is constructed 2,400(width) × 1,000 (length) × 2,100 (height) mm and consists of one column, two beams, two walls, and two slabs. This specimen is heated on one side with ISO-834 standard time-temperature curve for 2 hours and temperature distributions during the test are measured using thermocouples inside the structure. To investigate the relationship of temperature distributions between full-scale structure and a single member, the experimental results of full-scale structure are compared with those of a single member throughout the other experimental studies.

Abstract: In this study, the effective factors on the heat transfer and pressure drop in heat pipe heat exchanger design based on the LMTD and effectiveness-NTU has been investigated. Increasing fuel cost and energy conservation, fuel consumption and also, pollution air are the most important consideration to be taken in new heat exchanger design, and modern compact heat exchangers. This paper describes a theoretical method to the design and performance of heat pipe heat Exchanger. Design of heat pipe heat exchanger for identifying of the principal parameters, which can optimize the performance of heat exchanger. Heat pipe heat exchanger efficiency with copper pipes is 10% higher than steel but steel pipe for strength and its ability to heat recovery of hot gases is preferred. Increasing the number of rows of tubes will increase efficiency. The largest diameter pipes and increasing the number of fins improved efficiency. Pressure drop of the heat pipe heat exchanger placed as heat recovery unit
