Go out the instruction of unlatching, solenoid valve Y2, solenoid valve Y5, water circulating pump P1, water circulating pump P2, water circulating pump P3 are opened；It was condensed into
Cold high-pressure refrigerant passes through liquid and gaseous state mix refrigerant working medium of the expansion valve reducing pressure by regulating flow at low-temp low-pressure, into evaporation
Heat exchange is carried out after device with outdoor air, the liquid and gaseous state mix refrigerant working medium of low-temp low-pressure become the gaseous state of low-temp low-pressure
Refrigerant, the gaseous refrigerant for becoming high temperature and pressure by compressor exchanges heat with medium water within the condenser, after obtaining heat
Water is divided into two-way：Solenoid valve Y2 is flowed into all the way enters the storage that phase-change energy-storage water tank carries out energy, and phase-change energy-storage water tank bottom
Portion compared with the water of low temperature flow into solenoid valve Y5 under the promotion of water circulating pump P1 enter condenser in continue circulating-heating, until heat exchange
The temperature difference cannot meet cycle, and heat pump controller will make air source heat pump energy storage mode ends；Another way is pushed away water circulating pump P2's
Dynamic lower to enter water knockout drum, according to flow principle of equipartition, hot water uniformly flows into the fan coil in each room, and indoor cold
Air carries out heat exchange, water after cooling merged in water collector under the promotion of water circulating pump P3 flow into condenser again into
Row heat exchange, so recycles, and continues heat supply for room；When indoor occupant feels supercooling or overheat, independently parameter can be carried out
The indoor environment state of remotely modifying, the operational mode being optimal and the most comfortable；
During this period, the collected condenser out temperature pressure of each device controller, solenoid valve Y2 apertures, phase-change accumulation energy
Tank top bottom water temperature, phase-change energy-storage water tank water level line, the operating status of water circulating pump P1, water circulating pump P2 operation shape
The scene such as state, fan coil air outlet temperature air quantity pressure, return air inlet temperature air quantity pressure, water circulating pump P3 operating statuses is in real time
Data will be transferred to monitoring center database, and room monitoring computer also can extract each period to monitoring center database
Data, in case real time monitoring.
