The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, the round-the-clock hot-water heating system of a kind of solar heat pump, comprise attemperater 1, cold water oral siphon 2, the hot water outlet pipe 3, return pipe 4, solar thermal collector group 5 and source pump 6, between described attemperater 1 and described source pump 6, be connected with heat pump cycle pump 7, described cold water oral siphon 2 comprises first oral siphon 9 and second oral siphon 10, described first oral siphon 9 is connected with the following circulation port of described solar thermal collector group 5 by solar energy circulating pump 8, upper cycling mouth in described solar thermal collector group 5 is provided with magnetic valve 11 and temperature probe, and described second oral siphon 10 is connected with described source pump 6.Described source pump 6 is the directly-heated type source pump, is provided with liquid-level probe and fluid level controller in the described directly-heated type source pump, is connected with a cold water filter 12 between described second oral siphon 10 and described source pump 6.

The operation principle of the round-the-clock hot-water heating system of the utility model solar heat pump: the utility model uses an attemperater 1, and solar energy and air source heat pump all adopt the directly-heated type heating, finish solar energy and the independent separately heating of source pump 6 by two cover high water tank controls.Cold water is divided into two-way, one the tunnel advances the directly-heated type source pump, reach 55 ℃ by directly-heated type source pump heating back water temperature, enter attemperater 1, liquid-level probe and fluid level controller that the directly-heated type source pump is carried by unit are controlled, spring, summer, autumn can and be arranged on 3/5ths positions of water tank height with source pump 6 full water site adjustment, and source pump 6 full-water level show and are 50% state; Another road cold water enters the following circulation port of solar thermal collector group 5 by solar energy circulating pump 8, upper cycling mouth in solar thermal collector group 5 is provided with a magnetic valve 11 and temperature probe, daytime is when sunlight irradiation intensity is big, when solar thermal collector group 5 heating temperatures rise to set water temperature, solar energy circulating pump 8 and magnetic valve 11 synchronous operations, open, high-temperature water in the solar thermal collector group 5 enters in the attemperater 1, after the water temperature of upper cycling mouth in the solar thermal collector group 5 drops to design temperature, solar energy circulating pump 8 and magnetic valve 11 are closed, out of service, continuing to accept sunlight irradiation heats up, so constantly circulation, 2/5ths vacant volumes in the continuous subsidiary water tank, after attemperater 1 water was full, solar energy was subjected to full-water level control to stop moisturizing.Whole hot-water heating system is in running, because system is round-the-clock heat supply water, water level is not parked in continuous decline, as long as attemperater 1 does not reach full-water level, solar energy just can constantly preferentially replenish hot water.Overcast and rainy, do not have night when sunshine or daytime, sunlight irradiation intensity was little, solar thermal collector group 5 stop moisturizing or the additional water yield not enough, the water level of attemperater 1 in use descends, when water level drops to the low water level of source pump 6 settings, the directly-heated type source pump starts heating, subsidiary water tank hot water, as long as configure the water tank water level of guaranteeing the minimum, water tank is lack of water not, just can guarantee the regular supply of hot-water heating system, winter environment temperature is low, and the heat production of solar energy does not reach ideal effect, full-water level that can source pump 6 is set to 75%, the vacant amount of water tank reduces, and the source pump 6 heat production water yields increase, under the extreme severe cold condition, the full-water level of source pump 6 is set to 100% water tank and is full water state, guarantees hot water demand's amount.No matter under which kind of duty, when the water tank water temperature was reduced to the low water temperature of setting, the water pump of source pump 6 circulation waterways can be drawn back the water in the water tank unit automatically and do the circulation heating again, guarantees water temperature, does not change the water yield of setting.

Should be noted that at last; above content is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from the essence and the scope of technical solutions of the utility model.
