Virtual design on the heat pump refrigeration cycle: challenges and approaches
International Journal of Air-Conditioning and Refrigeration - Tập 32 Số 1
Yoon Jei Hwang, Noma Park
AbstractVirtual product design (VPD) of the refrigeration cycle has long been a major subject of many engineers and manufacturers. Issues should be the question of how simulation gets close to the real world in virtual ways. It is especially true when we consider variable refrigerant flow (VRF) heat pumps, having various types of indoor unit combinations, long and ...... hiện toàn bộ
Ventilation methods to prevent the spread of airborne pathogens from teachers to students
International Journal of Air-Conditioning and Refrigeration - Tập 31 - Trang 1-12 - 2023
Chang Heon Cheong, Seok-Ho Hwang, Beungyong Park
This study investigates different ventilation systems to prevent the spread of airborne pathogens from teachers in an elementary school classroom setting. The analyzed systems include a general mechanical ventilation system and a hybrid ventilation system. The hybrid ventilation system used a combination of natural ventilation, general mechanical ventilation, and local mechanical ventilation syste...... hiện toàn bộ
Performance analysis of a novel ejector-assisted condenser outlet split dual-evaporator refrigeration system
International Journal of Air-Conditioning and Refrigeration - - 2024
Gulshan Sachdeva, Parinam Anuradha, Vaibhav Jain, Y. T. VenkataTeja
The performance of an ejector-assisted condenser outlet split dual-evaporator cycle is compared with a conventional dual-evaporator cycle albeit consisting a pressure reducing valve. The cycles do not employ any separator due to its inability to efficiently separate the liquid and the vapor phases. The comparison of both the cycles has been made for the same cooling capacity in low-temperature eva...... hiện toàn bộ
Tối ưu hóa việc thu hồi nhiệt của bộ trao đổi nhiệt dạng ống và bó ống với các baffle xoáy liên tục cho hệ thống thông gió bằng khí Dịch bởi AI
International Journal of Air-Conditioning and Refrigeration - Tập 32 - Trang 1-16 - 2024
Md Ashfaqul Bari, Manuel Münsch, Bastian Schöneberger, Bernhard Schlagbauer, Andrea Alina Tiu, Andreas Wierschem
Chúng tôi báo cáo một đánh giá định lượng về tác động của baffle xoáy liên tục lên hiệu suất thu hồi nhiệt của các bộ trao đổi nhiệt dạng ống bó theo chiều đối lưu. Góc nghiêng của baffle đã được thay đổi từ $$11^{\circ }$$ đến $$22^{\circ }$$. Do lưu chất chảy qua bó ống theo một góc do dòng chảy xoáy bên trong vỏ, bộ trao đổi nhiệt hoạt động theo chế độ đối lưu chéo. Các mô phỏng bằng phần mềm F...... hiện toàn bộ

Design optimization of cross-counter flow compact heat exchanger for energy recovery ventilator
International Journal of Air-Conditioning and Refrigeration - Tập 30 - Trang 1-15 - 2022
Won Seok Kim
Energy recovery ventilators (ERVs) are the key equipment to fresh air ventilation, which is helpful for the control of respiratory diseases like COVID-19. In this paper, design optimization of the compact heat exchanger in a proposed heat recovery ventilator of the energy efficient building has been carried out and discussed. Appropriate theoretical models are required to evaluate system performan...... hiện toàn bộ
Effect of gas spacing and resonance frequency on theoretical performance of thermoacoustic refrigerators
International Journal of Air-Conditioning and Refrigeration - Tập 31 - Trang 1-14 - 2023
B. G. Prashantha, S. Seetharamu, G. S. V. L. Narasimham, K. Manjunatha
In this paper, the design and analysis of 500 W thermoacoustic refrigerators for the temperature difference of 28 K using helium and air are discussed. Helium is the best working gas, but air is chosen to study the possibility of replacing helium for the future cost-effective refrigerator since it is much cheaper than helium. Heat and work flow equations of thermoacoustic refrigerators are discuss...... hiện toàn bộ
Investigating the impact of indoor temperature on the performance of the retail commercial refrigeration system
International Journal of Air-Conditioning and Refrigeration - Tập 30 - Trang 1-27 - 2022
Oliver Brownbridge, Matthew Sully, Joshua Noons, Ibrahim M. Albayati
Commercial food outlets in the UK are responsible for 3% of the UK total energy consumption, with refrigeration systems account for 29% of this total. In this paper, a validated model that simulates a commercial refrigeration system installed over 2000 sq. ft to mimic a real express store installed at the Riseholme Refrigeration Research Centre at the University of Lincoln, UK, is presented.

Experimental study of the influence of pad angle on the thermal performance of a direct evaporative cooling system
International Journal of Air-Conditioning and Refrigeration - Tập 31 - Trang 1-12 - 2023
M. Mehrabi, K. Goudarzi, S. Davoodabadi Farahani
One of the most important parts of direct evaporative cooling systems is the cooling pad. Pads vary in materials and construction features. The parameters studied in the performance of the pads are air speed, pad thickness, geometrical characteristics, and its configuration and the provided water flow rate. The performance of the pads is usually determined through saturation efficiency, pressure d...... hiện toàn bộ
Introduction to magnetic refrigeration: magnetocaloric materials
International Journal of Air-Conditioning and Refrigeration - Tập 31 - Trang 1-13 - 2023
Souheila Mellari
This work presents a review of research work on the magnetic refrigerator, of which different research is presented. The principle of magnetic refrigeration at room temperature and its interests has been shown. The phase transitions, first-order and second-order, have been shown with the advantages and disadvantages of both. Indeed, the first-order materials benefit from high magnetic entropy and ...... hiện toàn bộ
Performance and design analyses of various configurations of dew point evaporative cooling-based desiccant air-conditioning (DAC) systems for hot and humid conditions
International Journal of Air-Conditioning and Refrigeration - Tập 30 - Trang 1-14 - 2022
Marco Lao, Jie Lin, František Mikšík, Kyaw Thu, Takahiko Miyazaki
Thermally driven desiccant- and evaporative cooling-based technologies are promising greener and cheaper alternatives to compressor-based systems due to the separate handling of latent and sensible loads. Desiccant air-conditioning (DAC) systems comprise a desiccant dehumidifier, a sensible cooling unit, a heat source for regeneration, and a heat recovery unit. These components of a DAC system can...... hiện toàn bộ
