Installation frigorifique et de chauffage d'un supermarché utilisant des pompes à chaleur à hydrocarbures et un groupe refroidisseur de frigoporteurs à ammoniac.

A supermarket refrigeration and heating system using hydrocarbon heat pumps and an ammonia chiller.

Résumé

The authors present different concepts on the use of ammonia and hydrocarbons in indirect (dual loop) refrigerating systems in supermarkets. The work shows that indirect systems may attain the same efficiency and lower total equivalent warming impact (TEWI) than conventional direct expansion systems, and the use of only natural working fluids in such systems is feasible. However, there are a number of practical problems to be overcome, particularly in the small hydrocarbon units required, and the reliability and practicability of the ammonia systems.
