NH3/LNO3 kullanarak absorpsiyon makineleri için çok fazlı buhar üreticisi/ayrıştırıcısı olarak çizgisel güneş alıcısının performan değerlendirmesi

A parabolic trough solar collector acting as a desorber (vapor separator) has been recently suggested (Lecuona-Neumann, Rosner, & Ventas-Garzon, 2016) and (Famiglietti et al. 2018). The desorber significantly reduced the complexity and cost of a solar driven absorption heat pump. However, it introduced an innovative flow layout, which is a two-phase, boiling, gravity driven and stratified counter flow. The comprehension of its capabilities is necessary in order to unveil its potential. In the current work, a simplified assumption of the complex flow is suggested and implemented in finite difference and thermodynamic simulations of a single-effect absorption cycle acting as an air cooled chiller using NH3/LiNO3 as the working fluid. The performance of the cycle has been investigated for satisfying the cooling demand of a representative living apartment in the Mediterranean climate. The results of the simulations are compared with experimental data.
