Article: Thermochemical Resorption Heat Pump Module: Case study with UK climate Siddhesh Pawar (24932842) Zacharie Tamainot-Telto (24635721) Steven Metcalf (24636270) Energy generation, conversion and storage (excl. chemical and electrical) Adsorption Ammonia COP Heat Pump Metal Halide Salts Resorption <p dir="ltr">Resorption systems (RES) utilize the difference in ammonia equilibrium of two distinct salts to produce useful heating/cooling. The salt with comparatively lower ammonia affinity is used as a Low Temperature Salt (LTS) and the other as a High Temperature Salt (HTS), in a two-reactor system. In this work, BaCl₂, MgCl₂, NaBr, NH₄Cl and SrCl₂ are paired with 18 different HTS’s, each pair is studied, thermodynamically mapped for high/ low operating temperature, pressure, COP and energy output value. NH₄Cl and NaBr are found to be the most promising LTS’s while SrBr₂ and MnSO₄ are found to be the best HTS’s. The resulting four combinations can be used for residential heating in the United Kingdom. The thermodynamic cycle evaluations suggest that the COP range lies between 1.10-1.50. In addition, more than 4140 J g_NH3^-1 of heat energy can be delivered using these pairs for residential heating at 50℃.</p> 2026-09-15T12:42:13Z Dataset Dataset 10.6084/m9.figshare.33792865.v1 https://figshare.com/articles/dataset/Article_Thermochemical_Resorption_Heat_Pump_Module_Case_study_with_UK_climate/33792865 CC BY 4.0
