摘要： The present invention relates to an air-conditioning apparatus which is capable of performing a cooling operation in a stable manner in an environment having a low outside temperature. The air-conditioning apparatus according to the present invention comprises: a housing including an inlet, a bypass inlet, and an outlet; a fan configured to introduce air into the housing and discharge the air from the housing; a heat-exchange flow path deposed between the inlet and the outlet; a heat exchanger disposed at the heat exchange flow path; and a bypass flow path disposed between the bypass inlet and the outlet.

摘要： A conditioning unit (10) of the indirect free cooling type, particularly for conditioning computing centers, of the type comprising: - an air/air heat exchanger (11), inside which two air flows (12, 13), exchange heat: a primary air flow (12) from and toward an environment to be air-conditioned (14), and a secondary air flow (13), or process flow, drawn from outside, - first fans (15) for moving the primary air flow (12), - second fans (16) for moving the secondary air flow (13). The conditioning unit (10) comprises: - means (17, 18, 19) for detecting temperature and humidity for the primary flow (12) and the secondary flow (13) at the inlet of the conditioning unit (10) and for the primary flow (12) at the delivery toward an environment to be air-conditioned (14), - means (20, 21) for detecting the flow-rate of the primary flow (12) and of the secondary flow (13), - means (22, 23) for detecting the electric power absorbed by the first fans (15) and the second fans (16), - an electronic control and management unit (24) adapted to collect and process the data detected by the detection means (17, 18, 19, 20, 21, 22, 23) and, on the basis of the detected data, adapted to adjust the speed of the first fans (15) and the second fans (16).
