Patent ID: 7360375

Claim:
A system (SC) for controlling the climate in an environment, including a first, vapour compression circuit (A), including a compressor ( 1 ) the output of which is connected to a condenser ( 2 ; 2 ′) followed by an expansion device ( 4 ) and an evaporator ( 5 ; 16 ) the output of which is connected to the intake of the compressor ( 1 ); a second, absorption circuit (B) which, in operation, has a hygroscopic solution flowing through it and includes a semipermeable-membrane regenerator ( 11 ) operable to allow the said solution to give up moisture (water) to a first airflow flowing in the regenerator ( 11 ) during operation, a dehumidifier with semipermeable membranes ( 13 ), arranged downstream of the regenerator ( 11 ) and operable to allow moisture to pass from a second airflow to the hygroscopic solution, and a circulation pump ( 14 ); the first and the second circuits (A, B) being connected by at least one heat exchanger ( 5 ) in which the hygroscopic solution flowing through the second circuit (B) give up heat to the cooling fluid flowing through the first circuit (A).
