Abstract

Nowadays, the use of hybrid systems has become very common all over the world. In this study, the aim is to minimize the use of grid energy to provide heating and cooling energy with the help of a hybrid heat pump equipped with a flat solar collector, phase change material (PCM), and photovoltaic (PV) panels. To achieve the best results, a numerical dynamic model consisting of different solar PV panels in three models, batteries, inverters, and hybrid heat pump along with collector and PCM has been modeled by solving Engineering Equation Solver (EES) and TRNSYS software. According to the proposed scenarios, multi‐objective optimization has been done to simultaneously improve the study answers in several sections by multi‐objective particle swarm optimization algorithm with MATLAB software. Also, economic and environmental optimization is also presented separately for comparing and reviewing solutions. The results of multi‐objective optimization show that the amount of lifecycle cost (LCC) when using polycrystalline panel is 21.26% lower than monocrystalline panel and 38.71% higher than thin film panel. As a result, according to the specific conditions and attitude, you can choose the desired system. Also, in the economic optimization, it was found that the best system is related to the polycrystalline panel, the volume of PCM used in the system is equal to 1 , the number of panels used is 18, and the minimum amount of LCC is $3929.08.

带有太阳能集热器和 PCM 的优化混合光伏热泵系统的能量、放能、放能经济和环境评估

如今，混合系统的使用在全世界已非常普遍。在这项研究中，目的是借助配备了平面太阳能集热器、相变材料（PCM）和光伏（PV）板的混合热泵，最大限度地减少电网能源的使用，从而提供供热和制冷能源。为了达到最佳效果，通过求解工程方程求解器（EES）和 TRNSYS 软件，建立了一个数值动态模型，该模型由三种型号的不同太阳能光伏板、蓄电池、逆变器、混合热泵以及集热器和 PCM 组成。根据提出的方案，利用 MATLAB 软件的多目标粒子群优化算法进行了多目标优化，以同时改进多个部分的研究答案。此外，还分别进行了经济优化和环境优化，以比较和审查解决方案。多目标优化结果表明，使用多晶面板时的生命周期成本（LCC）比单晶面板低 21.26%，比薄膜面板高 38.71%。因此，根据具体条件和态度，可以选择所需的系统。另外，在经济优化中，发现最佳系统与多晶面板有关，系统中使用的 PCM 体积等于 1，使用的面板数量为 18，最低 LCC 金额为 3929.08 美元。

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
