Central authorities' hot-water heating system
Technical field
The present invention relates to a kind of water heater, particularly a kind of central hot-water heating system.
Background technology
Along with energy scarcity, solar energy becomes more and more widely, solar water heater has become requisite electrical equipment in the productive life, traditional solar water heater, realize heating by solar thermal collector, the efficiency of heating surface is low, or adds electric heater, energy utilization rate is low, can not satisfy people's daily water consumption.
Summary of the invention
[1] technical problem that will solve
The technical problem to be solved in the present invention provides a kind of heat-collecting pump and solar energy in the central hot-water heating system of one.
The technical scheme of [2] dealing with problems
The invention provides a kind of central hot-water heating system, comprise solar thermal collector 5, heat pump 7, storage tank 8, water inlet pipe 12 and outlet pipe 13, described water inlet pipe 12 is connected the water inlet of described solar thermal collector 5 through filter 1 and magnetic valve 3 backs, the delivery port of described solar thermal collector 5 connects first water inlet of described storage tank 8, first delivery port of described storage tank 8 connects the water inlet of described solar thermal collector 5 behind circulating pump 4, second delivery port of described storage tank 8 connects second water inlet of described storage tank 8 behind described heat pump 7, the terminal delivery port of described storage tank 8 connects described outlet pipe 13 behind booster pump 9.
Further, between described filter 1 and described magnetic valve 3, be provided with electromagnetic cleaner 2.
Further, the delivery port of described solar thermal collector 5 is provided with first temperature sensor 6.
Further, be provided with second temperature sensor 10 in the described storage tank 10.
[3] beneficial effect
The present invention central authorities hot-water heating system there be not under the situation of the sun, by the heating of heat pump realization to water; Having under the situation of the sun, heat simultaneously by solar thermal collector and heat pump, heat effective, no electrical heating, environmental protection, electricity saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of the present invention central authorities hot-water heating system.
The specific embodiment
Below in conjunction with accompanying drawing, introduce the embodiment of the invention in detail.
Consult Fig. 1, the invention provides a kind of central hot-water heating system, comprise solar thermal collector 5, heat pump 7, storage tank 8, water inlet pipe 12 and outlet pipe 13, water inlet pipe 12 is connected the water inlet of solar thermal collector 5 through filter 1 and magnetic valve 3 backs, the delivery port of solar thermal collector 5 connects first water inlet of storage tank 8, first delivery port of storage tank 8 connects the water inlet of solar thermal collector 5 behind circulating pump 4, second delivery port of storage tank 8 connects second water inlet of storage tank 8 behind heat pump 7, the terminal delivery port of storage tank 8 connects outlet pipe 13 behind booster pump 9; Between filter 1 and magnetic valve 3, be provided with electromagnetic cleaner 2; Delivery port at solar thermal collector 5 is provided with first temperature sensor 6, is provided with second temperature sensor 10 simultaneously in storage tank 10.
In the present embodiment, water filters through filter 1 behind water inlet pipe successively, enter solar thermal collector 5 heating behind electromagnetic cleaner 2 scale removal and the magnetic valve 3, flow in the storage tank 8 from solar thermal collector 5 delivery ports through heated hot water, be provided with temperature sensor in the storage tank, cross when temperature and the water in the storage tank 8 can be extracted solar thermal collector again when low and heat, or heat by heat pump, when need are used hot water, can extract from the terminal delivery port of storage tank 8.
The present invention central authorities hot-water heating system there be not under the situation of the sun, by the heating of heat pump realization to water; Having under the situation of the sun, heat simultaneously by solar thermal collector and heat pump, heat effective, no electrical heating, environmental protection, electricity saving and energy saving.
