Développement d'une pompe à chaleur à deux circuits pour le chauffage et l'approvisionnement en eau chaude domestique.

Development of a two-circuit heat pump for heating and domestic hot water supply.

Auteurs : MÜLLER B.

Résumé

With the so called two-circuit heat pump it is possible to serve two different heat demands at different temperature levels. In parallel operation, the heat of lower temperature from the condenser is fed for instance in the floor heating while the hot water tank is charged by the circuit of higher temperature from the desuperheater. The design of a pilot-heat pump installation is described, measuring results obtained at a customer installation are discussed and possibilities for optimisation are pointed out. The COP at different working points and the seasonal performance factor is discussed. The described heat pump system is a ground coupled (bore holes) brine/water heat pump supplying a low temperature floor heating and domestic hot water production.
