不同功率驱动系数下光伏直驱冰蓄冷空调系统性能及老挝地区适用性分析
|
摘要
对光伏直驱冰蓄冷空调系统压缩机在不同驱动功率配比下的实验数据进行分析,结果表明,驱动功率系数为1.17时系统具有较高的运行稳定性,功率系数为1.02时适用于晴天工况,系数为0.88时长期欠功率运行会影响压缩机使用寿命.根据老挝气象数据对比分析可得,所设计系统在老挝不同地区均具有较好适用性,可以满足不同地区的用冷需求,为太阳能光伏空调在老挝及其他东南亚国家的推广使用提供理论及实践基础.
The tests and experiments under different power ratio are conducted to evaluate the performance of the ice storage air conditioning system.The results of the experiment reveal that the proposed system ran quite stably when the power ratio was 1.17,ran stably in sunny day when the power ratio was 1.02,but the life of the compressor was influenced when the power ratio was 0.88 because the compressor ran with prolonged low power.Furthermore,according to the comparative analysis of the meteorological data of Laos,the proposed system is possible to provide the cooling load which is sufficient for different regions of Laos.The research results also can provide the theoretical and practiced basics for the ice storage air conditioning system in large-scale applications in Laos and south-east Asian countries.
