By manually completing, can also be switched according to intensity of solar radiation and the feedback signal control valve of water tank leaving water temperature automatic
Switching.Conversion between solar water heater operational mode and the solar water heater operational mode of heat storage state can then pass through
Controller is automatically performed.When fine day intensity of solar radiation is sufficiently high, controller is by adjusting electric T-shaped valve 1 so that refrigerant
It can only be flowed along BC directions, regulation electric T-shaped valve 13 causes refrigerant to be flowed along EF directions, when in condenser/water tank 10
Hot water temperature reach domestic hot-water needed for temperature when condenser/water tank and phase are flowed through by the distribution of the aperture of electromagnetic valve for adjusting 15
Become the refrigerant flow of regenerative apparatus, so that rich heat storage be got up, it is ensured that the collecting efficiency of heat collector.At night or
When the intensities of solar radiation such as person's rainy weather are weaker, controller regulation electric T-shaped valve 1 causes refrigerant to be flowed along AC directions
Dynamic, regulation electric T-shaped valve 13 causes refrigerant to be flowed along DE directions, is opened completely while electromagnetic valve for adjusting 15 is in all the time
Open state.Heat stored in daytime phase transition heat accumulation unit is sufficiently utilized, lifting system COP.
