<<  Une pompe à chaleur est-elle capable de rafraîchir une maison ?  >>

Answer: yes, if it is a reversible heat pump.

Heat pumps are capable of cooling a home, but only the reversible models that have been designed for this use. Not all heat pumps offer this service. Among the reversible heat pumps, there is only the air-air aerothermal heat pump which allows the air conditioning of a home with real efficiency. Concretely, unlike its usual use, the heat pump will draw hot air inside the house or building to lower the temperature. Other reversible heat pumps can also be used to cool (more or less) the housing: the air-water and water-water heat pumps. The freshness being diffused through fan coils or a heating-cooling plan. However, their efficiency is much lower than the air-air heat pump.
