• Resumen

  • The refrigerant amount reduction is a matter of increasing importance because of the rise in prices of current hydrofluorocarbons and the safety reasons of the leading natural alternatives. There is no space for the refrigerant deposit in vapour compression cycles with refrigerant charge optimised; consequently, it is essential to know which refrigerant charge will make the vapour compression cycle work with the best performance during a year. In this work, a simulation of the different tests of the seasonal COP campaign for a brine-water heat pump is performed using the software IMST-ART. With the results, it can be possible to understand the different behaviour of the heat pump during the year and guess the best criteria to establish the optimum refrigerant charge.
