“…TRNSYS is a transient system simulation application that is used to model and simulate the performance and the behaviour of systems as a function of time. To simulate the complete system in TRNSYS, the first step is to identify the individual components whose collective performance describes the performance of the whole system [1].…”

“…Another problem is to obtain the performance of solar collectors by experimental investigations. In fact, the experimental method to predict the effect of the parameters that influenced solar collectors is time consuming and costly, so the alternative way to analyse the solar hot water system for long-term performance is the use of simulation software [1].…”

This paper presents a novel whey drying plant assisted by solar energy. In Italy, the whey is mostly used for feeding pigs and, regrettably, in the worst cases, it is discharged against the regulations to avoid significant disposal costs. Current technologies for the whey drying process are very polluting and expensive. Therefore, it is necessary to evolve the technologies for such processing to safeguard the environment and reduce operating costs. The plant is equipped by concentrated solar collectors which process the heat necessary to evaporate the whey in a vacuum dryer at a temperature equal to 65°C. In addition to the solar collectors, a boiler is present. The processed product is then deposited in a storage tank for its conservation. This thank is kept at a low temperature by an Ice Tank and an absorption refrigeration (H2O-BrLi) chiller. The warm water, which is heated by the field of the solar collectors, feeds the absorption chiller. A photovoltaic system electrically assists the pumps, thus making the entire system energy sustainable. The dynamic simulation of the processing of this drying plant is carried out by means of the TRNSYS software for the entire year. Solar fraction and efficiency of collectors are evaluated.

Solar water heating (SWH) systems becomes increasingly popular in modern buildings, due to significant reduction in energy consumption in heating applications. In this work, an active SWH is modeled using TRNSYS software for climatic conditions of Chennai, India, employing an external compound parabolic concentrator solar collector and stratified thermal storage system (STESS). The performance parameters are estimated on the basis of monthly and annual averaged solar fractions (SF) by varying the collector area, mass flow rate, various controller strategies, and STESS geometry. The simulated studies have specified the ability of the optimized system to supply the hot water demand of 280 L d−1 at 60°C, attaining a SF of 0.97. This design strategy can be implemented for the development of an efficient SWH system, utilizing zero energy consumption from conventional resources. The proposed TRNSYS model has been validated using experimental data under similar test conditions. An influence of placing XCPC under evacuated tubes is simulated, resulting 5% improvement in energy gained over an evacuated tube solar collector without XCPC.
