Heat pump technology is a battery thermal management with considerable potential and which has obvious advantages in environmental adaptability energy saving. The small-channel heat exchanger an important part of the system, uniformity two-phase refrigerant header branch channels one key issues that restrict performance system. In this paper, flow visualization phase separation experimental pla...

this paper proposes a method to solve multi-objective problems using improved particle swarm optimization. we propose leader particles which guide other particles inside the problem domain. two techniques are suggested for selection and deletion of such particles to improve the optimal solutions. the first one is based on the mean of the m optimal particles and the second one is based on appoin...

During the past two decades, the utilization of Active Chilled Beam (ACB) systems as promising air-conditioning systems has becoming increasingly prevalent in Europe, North America and Asia. However, the studies on air distribution of ACB systems are still inadequate. The air distribution has a great impact on thermal comfort. The ununiformity of air distribution will easily lead to turbulent f...
