Summary

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=βˆ’25 π‘‘π‘œβˆ’10 ℃; c) heat supply temperature 𝑇𝐺𝑂1, 2βˆ’πΈ π»πΆβˆ’π‘‰πΈπΆπ‘‡π‘‚π‘…=70 π‘‘π‘œ 170 ℃; d) new parameter, Temperature Regressive Difference, 𝑇𝑅𝐷=20 π‘‘π‘œ 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.
