由于潜在的能源成本节约和广泛的环境友好政策，太阳能的开发越来越受欢迎。在这种情况下，太阳能冷却是特别令人感兴趣的，因为在太阳辐射更丰富的地区和阳光充足的季节通常需要更大的冷却负荷。本工作的目的是评估整合传统的蒸汽压缩循环与太阳能喷射循环的潜在效益，以利用太阳能，而不影响夜间或阴天制冷的可能性。为了模拟太阳能循环、弹射循环和传统循环的行为，建立了一个数值模型。考虑到天气数据和全球工厂的性能，该模型之后被用来估计一组全球性能参数。
Exploitation of solar energy is becoming increasingly popular thanks to the potential saving on energy costs and to widespread environmental friendly policies. In this context, solar cooling is particularly interesting since greater cooling loads are usually needed in areas where the solar radiation is more abundant and during sunny seasons. The present work aims to evaluate the potential benefits of integrating a traditional vapour compression cycle with a solar powered ejection cycle, in order to take advantage of solar energy without prejudicing the possibility of cold production during night or cloudy days. A numerical model is implemented in order to simulate the behaviour of solar capitation circuit, ejection cycle and traditional cycle. Considering weather data and global plant performance, the model is thereafter used to estimate a set of global performance parameters.
