“…Substantially there is lack of studies about the use of desiccant wheels for air humidification. La et al [16] and Zeng et al [17] investigated a solar heating and humidification system with a one-rotor two-stage desiccant device. Outside air is provided to the building environment while return air is used as moisture source.…”

“…Outside air is provided to the building environment while return air is used as moisture source. The first work [16] mainly deals with the experimental and theoretical analysis of the system while the second one [17] deals with its numerical optimization. They highlighted the system can improve occupants' comfort due to the increase in relative humidity, which is not strictly controlled, compared to an equivalent system without desiccant rotor.…”

“…The counter‐flow heat exchanger of TRNSYS Type 91, which relies on an effectiveness minimum capacitance approach, was used. The heat exchanger effectiveness is assumed to be 0.8 57 . In the constant effectiveness mode, the maximum possible heat transfer is calculated based on the minimum capacity rate fluid and the cold side and hot side fluid inlet temperature.…”

Hybrid solar thermal/photovoltaic‐battery energy storage system in a commercial greenhouse: Performance and economic analysis

et al. 2020

Performance and economic analyses of a hybrid solar thermal/photovoltaic‐battery energy storage (ST/PV‐BES) system for a commercial greenhouse were developed. One of the objectives of the study is to evaluate the best configuration of photovoltaic (PV) and solar thermal (ST) modules, and battery energy storage size to have the minimum levelized cost of energy. The system was economically optimized. Moreover, to assess the influence of economic parameters such as ST system cost, PV system cost, natural gas price, electricity price, and large renewable procurement (LRP) rate, a series of sensitivity analyses were undertaken. The results showed that the ST system cost and natural gas price were the most effective parameters on both levelized cost of energy and payback period. The role of future evolution of electricity, fuel cost, and financial incentives (LRP rate and carbon tax) in the economic performance of the system were also analyzed.

“…2.5 Building model A set of building models were created using TRNBUILD to simulate the performance of the UTC façade system as heating system in the winter [30] and together with the DEC in the summer. The set of simulations was created with a unique indoor thermal node [31], considering the influence of the volume to surface ratio by studying different building shapes. Three shapes were selected: compact, linear and tower.…”
