The outdoor uses a novel double-suction double-row compressor to compress the refrigerant to different pressure steps for heat exchange. By adopting a double condenser and a double-suction double-row compressor, the irreversible loss in the heat transfer process of the condenser is reduced and the heat exchange efficiency of the multi-row heat exchanger is improved through double condensation temperature. The photovoltaic direct-drive technology is adopted, and through the multi-power management coordination control, the energy complementation and the smooth switching technology, the power supply proportion of the commercial power and the 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.

When the water spraying device is adopted, water directly flows to fins and heat exchange tubes of the heat exchanger to evaporate through spraying pipes, and non-evaporated water flows to the water receiving disc to enter the water storage tank, and is pumped to the upper part or the front part of the heat exchanger again by the circulating water pump to circulate. If the spraying device is used, water is sprayed into the air for evaporation and cooling, and the cooled air flows through the heat exchanger for heat exchange.
The refrigerating unit adopts two heat exchangers at the outdoor side along the air flow direction, and the two heat exchangers have different condensation temperatures in a refrigerating mode. The low temperature condenser is located on the windward side, and the high temperature condenser is located on the leeward side.

The refrigerants of the high temperature evaporator and the low temperature evaporator are independent of each other. The air to be treated is cooled (not dehumidified) by the high-temperature evaporator, dehumidified (cooled) by the low-temperature evaporator, and then sent into a room after reaching the air supply condition. The purpose of independent temperature and humidity control is achieved.
When the unit operates in a heating mode, the indoor windward side heat exchanger is changed into a low-temperature condenser, and the leeward side heat exchanger is changed into a high-temperature condenser, wherein indoor air is preheated by the low-temperature condenser and then is further heated by the high-temperature side condenser and then is sent to the indoor.

The two paths of refrigerant come out and then are converged into the room. The refrigerant entering the room respectively enters the indoor windward side heat exchanger and the leeward side heat exchanger after passing through the first throttling device and the second throttling device, and the refrigerant coming out of the windward side heat exchanger enters the second air suction port of the compressor through the E port and the S port of the second four-way reversing valve. The refrigerant coming out of the indoor lee side heat exchanger enters the first air suction port (the high-temperature evaporator corresponds to the high-temperature condenser) of the compressor through the E port and the S port of the first four-way reversing valve. The photovoltaic panel collects solar energy and converts the solar energy into electric energy to be supplied to the indoor unit, the outdoor unit and the humidifying device of the air conditioner.
