Design and simulation of heat pumps and air-conditioning equipment using pure and mixed refrigerants with MoMo (Modular Modelling).

Author(s) : BENSAFI A., BORG S., NAZIRI I.

Summary

An approach to the steady-state simulation of heat pumps and refrigerating equipment is presented. Novel features of the proposed model are the strategy and formalism adopted in the programme development. Individual mathematical models for component design are linked to enable the simulation of a basic vapour compression cycle. The paper introduces some of the component modules, which can be used for pure as well as mixed refrigerants. Because numerous models can be used for a specific piece of equipment making up the whole refrigerating/heating unit, the modular modelling approach leads to a flexible and evolutive structure. The proposed model is validated with experimental results from an air-to-air split unit using R22 and a water chiller using R22 and R407C. Discrepancies smaller than 5% are obtained on the cooling duty and COP of the split unit and the chiller components.
