Performance d'une pompe à chaleur utilisant le CO2 en cycle transcritique pour la production simultanée de froid et d'eau chaude.

Performance of a transcritical CO2 heat pump for simultaneous refrigeration and water heating.

Résumé

A prototype transcritical CO2 heat pump was constructed to enable the simultaneous production of refrigeration at less than 0 °C and water heating to 90 °C for the New Zealand food processing industries. The performance of the prototype was measured across a range of operating conditions, before and after the addition of oil to the system. The optimum heating COP of the prototype was about 3 in most trials, but increased to 3.2 when operating the heat pump compressor at part-load with no oil in the system. The result of addition of oil is evaluated.
