Utilisation de la chaleur récupérée à basse température dans l'industrie grâce aux nouvelles pompes à chaleur à température élevée.

Utilization of industrial low-grade waste heat by means of new emerging high-temperature heat pumps.

Auteurs : BRONDUM P., MARKUSSEN M., REINHOLDT L.

Résumé

A project supported by the Danish Energy Agency has the objective to accelerate the implementation of new large (> 500 kW) high-temperature heat pumps by means of full-scale demonstration. High temperature is here defined as above 85ºC water temperature. In this project only natural refrigerants are investigated. Although many other factors besides heat pump technology influence the feasibility of such technology, these new products will through the combination of high output temperature, refrigerant type and size of commercially available heat pumps, dismantle some of the existing heat pump barriers. The first phase is to examine 4 different suitable refrigerants (and unit types): R717 in a Vilter/Star unit; hybrid (combination of R717 and R718); R744; and R718. The purpose of this examination is to make a map of which refrigerant is preferable for given conditions.
