Résumé

Recent works proposed the absorption Multi-Effect Refrigeration Technology (M-ERT), synergic coupling an Absorption Technology Section (ATS) with a Mechanical Vapor Compression Technology Section (MVCTS), according to Hybrid Compression Technology (HCT). This work continues M-ERT research. After introduction, research analyzes two common double-effect absorption cooling cycles from classic and feasibility increase points of view. The resulting new refrigeration cycle, 2-E HC VECTOR. is presented, its model is provided and model results are given. The model input data are: a) internal sink source temperature, 𝑇𝑀𝑐=𝑇𝐼𝑆𝑆=27 ℃; b) desorber inlet temperature, 𝑇𝐷𝐼=−25 𝑡𝑜−10 ℃; c) heat supply temperature 𝑇𝐺𝑂1, 2−𝐸 𝐻𝐶−𝑉𝐸𝐶𝑇𝑂𝑅=70 𝑡𝑜 170 ℃; d) new parameter, Temperature Regressive Difference, 𝑇𝑅𝐷=20 𝑡𝑜 60 ℃. The 2-E HC VECTOR benefits are: i) feasibility and exergy efficiency increase; ii) heat and work effectiveness increase by about 2.3 times as compared to classic absorption double-effect and MVCTS.
