TL;DR: In this paper, the authors reported a numerical analysis of a supersonic ejector in single-phase conditions using R134a as the working fluid and compared the predicted entrainment ratio with the experimental data of Garcia del Valle et al. (2014).
Abstract: The present work reports a numerical analysis of a supersonic ejector in single-phase conditions using R134a as the working fluid. A numerical benchmark of some thermodynamic and two-equation turbulence models has been carried out to highlight the numerical model offering the best compromise between accuracy and calculation cost. The validation is achieved by comparing the predicted entrainment ratio with the experimental data of Garcia del Valle et al. (2014). The k−ω SST model together with the REFPROP 7.0 database equation appears to be the best combination to predict accurately the ejector performance and capture the shock wave structure. The influence of the outlet temperature, the discussion about the validity of some assumptions made by one-dimensional (1D) models and the exergy analysis within the ejector for the present operating conditions will later be discussed in Part 2 (Croquer et al., 2015).

TL;DR: In this paper, a detailed screening heat pump model was used to compare the seasonal performance of ASHP vs GSHP in a residential building in the cold climate city of Montreal, and a life cycle cost analysis was performed to account for the difference between initial and 10-year operating costs of the two systems based on current prices in Quebec.

TL;DR: In this article, the types, characteristics, advantages and disadvantages of different adsorbents, refrigerants and working pairs are summarized, together with the models that describe the adsorption equilibrium.
Abstract: Solid sorption refrigeration is a type of environmental benign and energy saving technology and the sorbents utilized can be divided into physical, chemical and composite sorbents, according to the nature of the forces involved in the adsorption process. The types, characteristics, advantages and disadvantages of different adsorbents, refrigerants and working pairs are summarized in this paper, together with the models that describe the adsorption equilibrium. Moreover, some of the procedures to prepare composite adsorbents are presented. The application of different working pairs for different situations is related with the adsorption heat, the adaptability to the driving temperature and to the desired working pressure. The methods to measure the adsorption quantity of different working pairs are compared, and future research directions of adsorption working pairs are also analyzed.
