Description
technical field:
The present invention relates to a kind of solar water heater, particularly hot-water supply system and the intelligent control method of a kind of solar energy and wall-hung boiler interlock.
background technology:
Prior art has had solar water heater and burnt gas wall hanging furnace has been combined to use, solar water heater substitutes old-fashioned electric energy auxiliary heating with gas-aided heating, some courses of work are exactly that hot water in solar water heater is not while reaching design temperature, start burnt gas wall hanging furnace the water in solar water heater is heated to design temperature, as patent 200610082341.3 and patent 200720019424.8, but solar water is directly used in heating, easily pollute, and in winter, easily there is frost crack pipe situation; Some courses of work are the heat exchangers that has one group of heat exchanger being connected with solar thermal collector and one group of external Natural Gas Water Heater in press-bearing water tank, heat exchanger is immersed in water, as patent 200920289672.3, the easily fouling and then affect heat transfer efficiency on heat exchanger of such structure, just in case heat exchanger leak of liquid, also can pollute domestic water; Press-bearing water tank cost is very high simultaneously, and installation is very complicated, safeguards also very trouble; As patent 20120330458.4, use expansion drum, when increasing cost, need regular replenishment gas, loaded down with trivial details trouble, also loaded down with trivial details cost is many in maintenance.
In sum, different prior aries has different shortcomings, one of shortcoming: the hot water of confession in solar water heater, circulate, in the harder easy fouling of the long-time use in place of water quality, the solar water heater heat-collecting Efficiency Decreasing making, cause whole system unstable, a large amount of foulings cause the more increase frequency of exchange device, in winter and cold or long-time situation about not using, all can cause water pipe to freeze or bursting by freezing, cause and can not use or device damage, very inconvenient and dangerous.Two of shortcoming: there is no intelligent controlling device, need artificial in time upper water, bother time-consuming bothersomely, just can not run well unmanned in the situation that; Can not divide situation Energy Saving Control, cause the waste of the energy.Three of shortcoming: there is no the attemperater water heater of retaining, the in the situation that of a large amount of water, hydraulic pressure water temperature is non-constant, the in the situation that of a small amount of water, needs debugging, wastes the inappropriate water of large amount temperature.Four of shortcoming: use press-bearing water tank cost very high, and install very complicated, safeguard also very trouble, some is that heat-exchanger rig is passed in press-bearing water tank, such one is easily fouling reduction heat-conducting effect of heat-exchanger rig outside, the one, and heat exchanging liquid leaks in water tank can pollute domestic water.Five of shortcoming: combustion gas auxiliary equipment does not have heat-exchanger rig, if directly pass into running water through gas heating, easily accumulates incrustation scale blocking pipe, if gas heating treated water, for domestic water, causes water cost greatly to increase.
