摘要/Abstract

摘要：

为了探究严寒地区相变日光温室蓄放热性能的影响因素及其内在规律，首先，基于TRNSYS软件构建全尺寸相变日光温室模型，并进行试验验证其可靠性及准确性。随后，利用此模型探究温室跨度、北墙高度、传热系数等围护结构参数以及相变温度、相变潜热、相变材料用量等相变材料参数对相变温室空气平均温度、有效积温的影响情况。最终，使用SPSS进行多因素回归分析确立了有效积温与上述各个参数之间的非线性回归方程。在本试验工况下，通过数据分析获得以下结论：有效积温和空气平均温度随温室跨度和北墙传热系数的增大而减小，呈现负相关，随北墙高度、相变潜热和相变材料使用量的增大而增大，呈现正相关；在相变温度为23 ℃时，空气平均温度和有效积温达到最大，分别为16.63 ℃、36.29 ℃·d；构建了有效积温与北墙传热系数、日光温室跨度、北墙高度、相变材料使用量、相变潜热、相变温度等参数的非线性回归方程。本研究为严寒地区相变日光温室的设计和改造优化提供了便捷手段。

Abstract:

In this study, we explore the factors that influence and the inherent laws that govern the heat storage and release performance of phase-change solar greenhouses in cold regions. First, a full-scale model of a phase-change solar greenhouse was constructed using TRNSYS software, and its reliability and accuracy were verified through experiments. Subsequently, this model was used to investigate the effects of the structural parameters of the enclosure—such as the span of the greenhouse, the north-wall height, and the heat-transfer coefficient—as well as the parameters of the phase-change material—such as the phase-change temperature, latent heat, and phase-change material dosage—on the average air temperature and the effective accumulated temperature of the phase-change greenhouse. Finally, a nonlinear regression equation was established between the effective accumulated temperature and the aforementioned parameters using multiple regression methods within the SPSS software. The following conclusions were obtained by analyzing the data from these experiments: The effective accumulated temperature and the average air temperature both decrease as the span of the greenhouse and the north-wall heat-transfer coefficient increase, a negative correlation, and they both increase as the north-wall height, latent heat of the phase change, and phase-change material usage increase, a positive correlation. The effective accumulated temperature and the average air temperature reach their maximum values—16.63 ℃ and 36.29 ℃·d, respectively—at a phase transition temperature of 23 ℃. A nonlinear regression equation was constructed for the effective accumulated temperature in terms of the heat-transfer coefficient of the north wall, the span of the solar greenhouse, the north-wall height, material usage, latent heat of the phase change, and phase-change temperature. This study thus provides a convenient means for the design and optimization of phase-change solar greenhouses in severely cold areas.

Key words: solar greenhouse, phase change materials, heat storage and release performance, effective accumulated temperature, regression equations
