In a preferred embodiment the openable and closable means may be an electrically driven shutter or the like.
The openable device of the present embodiment is exemplified by an electric blind. As shown in fig. 1 to 3, the air inlet and the air outlet of the first housing portion of the fan chamber 102 may be the entire side wall of the air inlet side and the air outlet side of the first housing portion. Of course, the opening formed in the side wall of the first housing portion may be provided. The air inlet of the first shell part adjacent to the air inlet side of the first heat exchange part, namely the side wall 1023 of the first shell part on the air inlet side, is set to be in the form of an electric shutter, and the air outlet of the first shell part, namely the side wall 1021 of the first shell part on the air outlet side, is also set to be in the form of an electric shutter. More preferably, to ensure better air circulation and better heat dissipation from the fan compartment 102, the air intake of the first housing portion further includes an end sidewall 1022 of the first housing portion adjacent the end of the first heat exchanger, also provided in the form of an electrical louver.

When the air source heat pump unit 100 is in operation, relatively loud noise is generated. The noise of the air-source heat pump unit 100 mainly comes from the compressor 104 in the main room 103 and the fan 108 in the fan room 102, such as an axial flow fan in the present embodiment. The noise of the compressor 104 is greatly different from the noise of the axial flow fan. The compressor 104 noise is mainly mechanical noise generated by mechanical friction, and the sound pressure level and the sound power level of the mechanical noise are relatively large and have a long free propagation distance, but the mechanical wave wavelength is relatively short and is easily blocked by an obstacle. The noise of the axial flow fan is mainly wind noise generated by the friction between the rotation of the blades and air, and the pressure level and the sound power level of the wind noise are relatively small and the free propagation distance is short. In view of the above different source wave characteristics of the different noises, in a preferred embodiment of the present embodiment, a sound absorbing partition is provided in the main cabinet.
