EQUIPMENT INCLUDING A HEAT PUMP FOR HEATING AN EXTERNAL FLUID WITH A LARGE TEMPERATURE DIFFERENTIAL

摘要

The invention relates to equipment including a heat pump for heating an external fluid with a large temperature differential, said heat pump (10) including: first (11) and second (12) heat exchangers; a coolant; a coolant circuit including a compression unit (13) connected to an outlet of the first heat exchanger (11) and to an inlet of the second heat exchanger (12) and an expansion unit (14) connected to an outlet of the second heat exchanger (12) and to an inlet of the first heat exchanger (11), wherein the coolant is one of the coolants selected from among a hydrofluorocarbon coolant and a hydrofluoroolefin coolant, and wherein the second heat exchanger (12) and the coolant circuit are suitable for circulating the coolant in a transcritical cycle.
