Résumé

In order to improve the total COP of the small-sized LiBr absorption refrigeration machine driven by low grade heat energy, the authors developed a novel hollow fiber membrane solution heat exchanger with both heat transfer and water vapour transfer process to replace the traditional dividing wall type metal heat exchanger. They study the characteristics of the heat exchanger applied to the absorption refrigeration system. The results show that the heat exchanger can offer enormous contact area between high temperature solution from the generator and low temperature solution from the absorber, the temperature difference between inlet and outlet in both hot side and cold side is improved, water vapour transfer and latent heat transfer not only enhance the heat transfer effects, but also enlarge the deflation ratio of the system, the strong solution can be concentrated and the weak solution can be diluted further, and the heat load of generator and absorber can be reduced, and the COP of system will be improved.
