Method of supplying water in described step 2.2 is as follows:
First, carry out time judgement, determine that solar thermal collector 1 supplies water or air source heat pump I 5;
When solar thermal collector 1 supplies water:
Detect the temperature in preheating water tank 2, when water temperature is lower than predetermined temperature I, then carry out solar thermal collector 1 and supply water (even if the water temperature in solar thermal collector 1 does not reach predetermined temperature I, solar thermal collector 1 supplies water equally) yet;
If water temperature higher than or equal predetermined temperature I; supply water without the need to solar thermal collector 1;
When air source heat pump I 5 supplies water:
Detect the temperature in preheating water tank 2, when water temperature is lower than predetermined temperature I, then open heat cycles water pump I 4 and air source heat pump I 5 interlock, inputted in cold water to air source heat pump I 5 by filling pipe and be heated to predetermined temperature I rear input preheating water tank 2;
If water temperature higher than or equal predetermined temperature I; supply water without the need to air source heat pump I 5.
Above-described warning line limits accordingly with the size of constant temperature water tank 21 size and hot pipe network 8.And predetermined temperature I is traditionally arranged to be 40 degree (being advisable close to tap water temperature with 8:00 next day), predetermined temperature II is the water temperature used, and is traditionally arranged to be 50 degree.And in the water supply situation of solar thermal collector 1, if when current weather cannot meet the requirement of heating (referring to cold water to be warmed to predetermined temperature I) of water, the water not reaching predetermined temperature I is input in preheating water tank 2 by solar thermal collector 1.
And in the above process used, because night does not have sunshine, so solar thermal collector 1 cannot carry out work, if so collect in the daytime heat energy deficiency when, the use at night can be affected, so air source heat pump I 5 is arranged time switch, the mode of timing is adopted to make air source heat pump I 5 start the rule of use on time at night, for Zhejiang area (mainly according to water habits, the time at intensity of sunshine and sunshine limits): the 1-2 opening time in month is 16:00-8:00, the 3-4 opening time in month is 17:00-6:00, the 5-6 opening time in month is 18:00-0:00, 7-8 month is for closing, the 9-10 opening time in month is 18:00-0:00, the 11-12 opening time in month is 17:00-6:00.And in order to save the energy, on above-described temperature control mode, then formulate corresponding time controling criterion by various places different solar radiation level, the open and close of air source heat pump I 5 are limited by the double standards of temperature and time.Effect due to preheating water tank 2 is the buffering of carrying out hot water to the water entered in heating water tank 23, and when there is no the sun daytime, solar thermal collector 1 cannot absorb enough heat (only by absorptions such as ultraviolets, produce certain heat), now, the coolant-temperature gage in preheating water tank 2 lower than predetermined temperature I, and directly enters in heating water tank 23 with this temperature, carry out corresponding heating by heating water tank 23, it can not affect the water temperature in constant temperature water tank 21.
