[0197] In some embodiments of the present application, reference Figure 20-21 The water receiving tray may be provided with a diverter plate 312 arranged along the width direction of the chassis. The diverter plate divides the water receiving tray into two drainage paths arranged along the front and rear directions of the chassis. The diverter plate plays the role of diversion and drainage, avoids excessive concentration of condensed water, improves the drainage effect of the water receiving tray, and also plays the role of strengthening the chassis strength.

[0198] In some embodiments of the present application, reference Figure 20-21 The water receiving tray is provided with a guide plate 313 arranged along the width direction of the chassis. The guide plate is a segmented rib staggeredly distributed on both sides of the diverter plate. The guide plate can play a role in drainage, improve the fluidity of condensed water, and make the condensed water flow to the drain hole.

[0201] The height of the guide plate is greater than that of the diverter plate, so that the height of the diverter plate is not too high, and it can divert the water better. At the same time, it can divert the water evenly when there is more water in the water receiving tray, avoiding a large difference in the amount of water in the two water channels, the inability to share resources, and increased drainage time.

[0208] The compressor is arranged on the chassis and between the water pumping device and the indoor heat exchanger.

[0209] The parking air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator.

[0210] The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0211] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas.

[0212] The exhausted refrigerant gas flows into the condenser.

[0213] The condenser condenses the compressed refrigerant into liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0214] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0215] The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0216] The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled.

[0217] Throughout the cycle, the air conditioner can regulate the temperature of the indoor space.
