AI Technical Summary
In traditional heating systems, the heating hot water unit and the terminal return water share a water tank, which causes the water temperature in the tank to drop rapidly. In extremely cold weather, the heating temperature is insufficient and cannot meet the heating requirements.
A tonnage-type flat-top insulated water tank is used, which is equipped with multiple air source heat pumps and connected to the water supply and return pipes through rubber flexible joints. The buffer water tank and hydraulic balance pipe are used to control water level imbalance and increase the terminal temperature of the heating.
In extremely cold weather, the heating water temperature increases by 8-10℃, significantly raising the indoor temperature and achieving efficient and energy-saving heating.
