[0023] Example

[0024] This utility model features a matching air-cooled outdoor unit. Powered by a compressor, it forces the refrigerant into circulation. The refrigerant entering the thin-walled air handling unit is a medium-temperature, high-pressure gas-liquid mixture. After being throttled and depressurized by the solenoid valve and expansion valve components within the connecting pipe casing 50, it enters either the primary heat exchanger 21 or the secondary heat exchanger 22. The primary heat exchanger 21 causes the air on the application side to undergo cooling, condensation, and dehumidification under the power of the motor 31 and the fan 32. The secondary heat exchanger 22 causes the air on the application side to undergo heating and dehumidification. The circulating air on the application side undergoes heat exchange with the secondary heat exchanger 22. The temperature and humidity sensor 42 is connected to the control board of the control box 40. It compares and performs logical operations with the command values ​​set in the control panel 41, sending signals to control the opening and closing of the solenoid valve, thus completing the functional segment operation of the primary heat exchanger 21 or the secondary heat exchanger 22. The speed of the motor 31 and the fan 32 is adjusted according to the temperature and humidity control requirements to achieve precise temperature and humidity control. During maintenance, simply loosen the detachable bolts on one side of the motor panel 60 to allow the motor panel 60, along with the motor 31 and impeller 32, to rotate and open, enabling inspection and maintenance of the blower unit's interior.
