Heat exchange；When the water temperature of 18 water outlet of solar thermal collector is lower than the water temperature in conditioned water water tank 20, central controller
It controls second solenoid valve 2 to close, third solenoid valve 3 is opened, and the water in water tank carries out hot friendship with the water from air source heat pump 17
It changes；
Winter heat supply water: user sets in hot water controlling terminal set temperature when the water temperature of 18 water outlet of solar thermal collector is higher than
When determining temperature, the 4th solenoid valve 4 of central controller controls is opened, and the 5th solenoid valve 5 is closed, from 18 water outlet of solar thermal collector
The hot water of outflow carries out heat exchange in domestic water storage tank 21, and the coolant-temperature gage in water tank increases；When solar thermal collector 18
The water temperature of water outlet lower than set temperature but be higher than in domestic water storage tank 21 water temperature when, the electricity of central controller controls the 4th
Magnet valve 4 and the 5th solenoid valve 5 are opened, and the water in water tank carries out heat with from the water of solar thermal collector 18 and air source heat pump 17
Exchange；When the water temperature of 18 water outlet of solar thermal collector is lower than the water temperature in domestic water storage tank 21, central controller control
The closing of the 4th solenoid valve 4 is made, the 5th solenoid valve 5 is opened, and the water in water tank carries out heat exchange with the water from air source heat pump 17；
5. combined supply system automatically controls: central controller goes through the operating condition of combined supply system in one month and user's operation
Records of the Historian record, which is packaged, is transmitted to producer's server, and user data package is generated after server analysis is handled, is monthly updated, in conjunction with from mutual
Network obtain meteorological data, user behavior can be predicted, automatically control combined supply system, especially season more
It replaces, in the case where thermic anomaly, meets user's temporary demand；
6. System self-test: control system is divided by the measurement data of operating condition and each detection instrument to executing agency
Analysis judges whether each mechanism operating of combined supply system is normal, and prompts hidden danger by customer mobile terminal and human-computer interaction device
