Double supply system

The two combined supply system has been called "one source and two ends" by the heating industry since the beginning. The "one source" refers to the air source heat pump cooling and heating unit used as the cold and heat source, and the "two ends" refers to the end system in which the radiation coil and the fan coil coexist. All the rooms use water as the heat exchange medium (the fluorine fan uses the refrigerant for heat exchange). In summer, cold water is supplied, and low-temperature water is directly sent to the fan coil for refrigeration. In winter, hot water of about 45 ℃ is directly supplied from the outdoor unit for floor heating. The system cooperates with the stability of the secondary system of the buffer tank and the good thermal stability of the floor heating, and the overall stability of the system is high.
