Purpose The purpose of this study is to numerically and experimentally survey the thermal
efficiency of a block-type heat exchanger operated in different working conditions by using …

Positive displacement compressors are essential in many engineering systems, from
domestic to industrial applications. Many studies have been devoted to providing more …

Due to the thermal inertia of building envelope and random uncertainty of occupant
behaviors, real-time and accurate forecasting for building cooling and heating loads is not …

Considering the storage of solar energy, which is intermittent in nature, and its usage even
when it is absence, this study deals with the evaluation of thermal performance of a water-to …

The solar air collector assisted air source heat pump is demonstrated to be an efficient clean
heating technology, while the research on its working modes, and the corresponding …
