Pompe à chaleur d'efficacité élevée pour la production d'eau chaude domestique.

High efficiency heat pump for domestic hot water generation.

Auteurs : NEHME G., PALANDRE L., CLODIC D.

Résumé

A new concept of heat pump has been developed for domestic hot water (DHW) generation. The concept is based on recovery of heat on lukewarm wastewater recovered from sinks, showers, and bath tubes. The recovered lukewarm water is stored at atmospheric pressure in a tank. The typical average temperature of wastewater is of 31°C. The DHW is produced instantaneously by the heat pump and stored in a tank, and hot water is delivered at 61°C. Refrigerant blends showing different temperature glides have been developed in order to improve energy efficiency of the heat pump system. Simulations using dedicated software allowed calculating the annual energy consumption. Moreover, specific control has been developed taking into account the daily needs of DHW in hotels. Annual COPs of 7 have been reached.
