A novel double-suction double-row compressor is adopted outdoors to compress the refrigerant to different pressure steps for heat exchange. By adopting double condensers and a double-suction double-row compressor, the irreversible loss of the condenser in the heat transfer process is reduced and the heat exchange efficiency of the multi-row heat exchanger is improved through double condensing temperatures. By adopting a photovoltaic direct-drive technology and through multi-power management coordination control, energy complementation and smooth switching technology, the power supply proportion of commercial power and solar energy can be adjusted in real time according to the power required by the operation of the air conditioner and the photovoltaic power generation power, so that the efficient utilization of the solar energy is realized.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
