Abstract:
A double-stage capacity-variable compressor and an air conditioning system having the same. The double-stage capacity-variable compressor comprises a first cylinder group (10) and a second cylinder group (20). The first cylinder group (10) comprises: a first cylinder (11) having a first sliding slot (12) for a sliding vane and a first via (12a) that is in communication with the first sliding slot (12) for a sliding vane and used for receiving a high-pressure gas, a first sliding vane (14) that abuts against the circumferential surface of a centrifugally disposed first roller (30) and has a positioning slot (15), and a locking mechanism (16). The upper end of the locking mechanism (16) is in communication with the first via (12a), the lower end selectably receives a high-pressure gas or a low-pressure gas, so that the locking mechanism (16) has a locked position or an unlocked position. The second cylinder group (20) comprises a second sliding vane (23) that always abuts against the circumferential surface of a centrifugally disposed second roller (40).
