Abstract Photovoltaic (PV) air conditioning (AC) is an effective way to solve the problems of energy consumption of office buildings. In this study, a set of parameters were designed for PV AC, including PV capacity, AC parameter, and inverter parameter. Then, the parameters were applied to a 20-m2 office building, and a PV AC system test platform was built. The test lasted for one year; the corresponding data including typical daily data and annual data were collected and analyzed. The results show that the PV AC system quickly decreases or increases the room temperature by ~9.5% and 17% in 1 h of cooling and heating periods, respectively, thus maintaining the room temperature within the set temperature range of ±0.9 °C. The data also show that by proper design of parameters, a PV AC system can satisfy the electricity demand of AC. In the cooling period, heating period, and annual operation conditions, the PV system provided 114%, 73%, and 188% of the energy for the AC system, respectively. Next, economic calculations show that PV AC is suitable for office buildings. The local payback period is only 7.5 years; both the energy saving and emission reduction are significant.

基于办公楼的光伏空调系统设计及适应性

摘要 光伏（PV）空调（AC）是解决办公建筑能耗问题的有效途径。在本研究中，为光伏交流设计了一组参数，包括光伏容量、交流参数和逆变器参数。然后，将参数应用于20平方米的办公楼，搭建了光伏交流系统测试平台。测试持续了一年；收集和分析了相应的数据，包括典型的日数据和年度数据。结果表明，PV AC 系统在 1 h 的制冷和制热周期内分别快速降低或升高约 9.5% 和 17% 的室温，从而将室温保持在±0.9 °C 的设定温度范围内。数据还表明，通过适当的参数设计，光伏交流系统可以满足交流的电力需求。在制冷期、制热期和全年运行工况下，光伏系统分别为交流系统提供了114%、73%和188%的能量。接下来，经济计算表明，光伏空调适用于办公楼。当地投资回收期仅为7.5年；节能减排成效显着。
