Method and device for environment conditioning

摘要

A device for environment control in a space protected against an outside environment is disclosed. The device comprises a circuit with a first circuit portion in which a heat-absorbing medium (204) is arranged to pass through a first heat exchanger (203). A second circuit portion, which is connected in series with the first circuit portion, is arranged to pass the heat-absorbing medium through a second heat exchanger (207). Moreover, a third circuit portion is arranged to transmit heat absorbed by the heat-absorbing medium in the first circuit portion to an electrically driven refrigerating circuit. The second and third circuit portions are arranged in parallel and the device comprises a valve mechanism (209) for guiding the heat-absorbing medium to the second circuit portion when the valve (209) is in a first state and to the third circuit portion when the valve is in a second state.
