According to the whole-house internal circulation
air conditioning system and the whole-house five-constant
system, an internal circulation
air conditioning module is arranged, and a single-tube-pass pipeline
system and an
airflow relay channel are matched; the internal circulation air conditioner module, the internal circulation power point position in the internal circulation air conditioner module and the single-tube-pass pipeline system are matched to achieve air conditioner air leading-in towards a
public space and air flow air returning in a room, the air conditioner heat exchange module adjusts the temperature of the air conditioner air, and an air flow
relay channel serves as an air flow
relay node for breaking through the
public space and the room. And whole-house air-conditioning internal circulation is realized. According to the embodiment, the air conditioner indoor units (fan coils) of the
public space and all the rooms are combined into the unified internal circulation air conditioner module on the equipment platform, then the air conditioner indoor units of all the rooms in the room group can be removed, the main source of room
noise is eliminated from the source, and the
noise reduction effect is achieved. Comprise indoor unit fan
airflow noise, fan
mechanical noise,
refrigerant flow noise and drainage pump operation noise, and the building space constant static requirement is truly met.
