摘要

在工艺热应用的热冷却系统中，对使用LiBr-H2O的蒸汽吸收系统的设计进行了实验研究。设计并测试了LiBr-H2O蒸汽吸收系统在不同操作条件下的1.5kW冷却能力。改变了发生器温度、吸收器温度、冷凝器温度和蒸发器温度，分析了LiBr-H2O蒸汽吸收系统的性能。根据COP和循环比给出了实验结果。此外，为了验证结果，利用热力学第一定律建立了热力学模型，并在工程方程求解器中进行了模拟。通过模拟和实验估算出的COP和循环比与±5%的标准偏差吻合良好。此外，这项研究工作有利于乳制品行业在工艺热应用中的应用，并认识到乳制品行业节能需求的重要性。

Designing of system for high grade heat recovery in thermal coolingsystem for process heat applications

An experimental investigation on design of a vapour absorption system using LiBr-H2Ofor high grade heat recovery in thermal cooling system for process heat applications has been conducted. A 1.5 kW cooling capacityof the LiBr-H2O vapour absorption system has beend esigned and tested under various operating conditions. Generator temperature, absorber tem-perature, condenser temperature and evaporator temperature have been varied and perfor-mance of LiBr-H2O vapour absorption system has been analysed. Experimental results are presented in terms of COP and circulation ratio. Further, to validate the results thermody-namic model is developed using first law of thermodynamics and simulate in Engineering Equation Solver. The COP and the circulation ratio estimated through simulationsand exper-iments have been in good agreement with ±5% standard deviation. Further, this this research work is beneficial for dairy industries in process heat applications and realizing the impor-tance of the need for energy conservation in dairy industries.

期刊介绍： Journal of Thermal Enginering is aimed at giving a recognized platform to students, researchers, research scholars, teachers, authors and other professionals in the field of research in Thermal Engineering subjects, to publish their original and current research work to a wide, international audience. In order to achieve this goal, we will have applied for SCI-Expanded Index in 2021 after having an Impact Factor in 2020. The aim of the journal, published on behalf of Yildiz Technical University in Istanbul-Turkey, is to not only include actual, original and applied studies prepared on the sciences of heat transfer and thermodynamics, and contribute to the literature of engineering sciences on the national and international areas but also help the development of Mechanical Engineering. Engineers and academicians from disciplines of Power Plant Engineering, Energy Engineering, Building Services Engineering, HVAC Engineering, Solar Engineering, Wind Engineering, Nanoengineering, surface engineering, thin film technologies, and Computer Aided Engineering will be expected to benefit from this journal’s outputs.
