The paper presents the results of a theoretical analysis performed for a single-stage, water–lithium bromide absorption chiller at steady-state conditions. The model takes into consideration crosscurrent flow of fluids for heat and mass exchangers, two-dimensional distribution of temperature and concentration fields, local values of heat and mass transfer coefficients, thermal-parameter-dependent physical properties of working fluids and operation limits due to the danger of the LiBr–water hydrates and ice crystallisation. The main practical advantage of the model is the possibility to assess the influence of both the geometry parameters and operation parameters on thermal performance of the absorption chiller. The results derived from the implementation of the water vapour absorption process model for a horizontal tube absorber are consistent with the experimental measurements found in the literature.
