Abstract

The utility model discloses a household central solar heating system which is used for supplying heat to a floor heating system in a room. The household central solar heating system comprises a heat collector, a water tank and a floor of the floor heating system, wherein the water tank is connected with the heat collector through a pipeline; the floor of the floor heating system is connected with the water tank through the pipeline; the water tank is connected with a water cooling pipe; the floor heating system is provided with a basic layer, a plastic extruding polystyrene board layer, a heat insulation layer and a floor layer in sequence from bottom to top; water pipes which are arranged at intervals are arranged between the floor layer and the heat insulation layer, and phase change materials are filled between the adjacent water pipes. According to the utility model, phase change material bodies are filled in the floor heating system, so that the phase change material can absorb and store heat energy in the water when the floor of the floor heating system receives hot water supplied by the water tank, and the floor of the floor heating system can be continuously supplied with heat at night, so that the solar heating efficiency can be well improved, the capacity of the water tank is reduced, and the whole heating system can be stably used.

Description

The domestic central solar heating system

Technical field

The utility model relates to technical field of solar utilization technique, especially a kind of domestic central solar heating system.

Background technology

Regulation solar energy resources three class areas " solar energy fraction " in the solar heating standard as long as reach 10-30%, for a class area, also only need reach more than 50%.Formulate so low solar energy contribution rate, certain technology and economic cause are arranged, but be difficult to really bring into play the effect of solar energy after all, can't realize practical energy-saving benefit.Domestic central solar heating system commonly used when solar radiation is sufficient, can be brought into play the heating effect usually preferably, to evening lose when shining upon, just rely on the electric power heating fully, improved energy resource consumption, solar heating efficient can not get better utilization.

The utility model content

The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of domestic central solar heating system that can utilize solar heating better is provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of domestic central solar heating system, for indoor floor heating provides heat to the house, comprise heat collector, the water tank that links to each other with the heat collector pipeline and the ground heating floor that links to each other with the water tank pipeline, be connected with cold water pipe on the water tank, described ground heating floor is provided with basal layer, extruded polystyrene flaggy, thermal insulation layer and floor layer from the bottom up successively, be equipped with spaced water pipe between floor layer and the thermal insulation layer, be filled with the phase-change material body between the adjacent water pipe.

The pipeline that described water tank leads to ground heating floor is provided with supply-water pump, is provided with first controller that the control supply-water pump starts or cuts out between supply-water pump and the ground heating floor.

Pipeline between described heat collector and the water tank is provided with water circulating pump, is provided with electric heater in the water tank, is provided with second controller of control water circulating pump action between electric heater and the water circulating pump.

Described water tank also pipeline is connected with shower.

The beneficial effects of the utility model are: be filled with the phase-change material body in the ground heating floor of the present utility model, accept the hot water while that water tank provides at ground heating floor, the heat that the phase-change material body can absorb in the hot water is stored, continue to the ground heating floor heat supply to evening, thereby improved solar heating efficient better, solar energy utilization ratio can be brought up to more than 80%, has also reduced the capacity of water tank, is conducive to the stable use of whole heating system.

The specific embodiment

By reference to the accompanying drawings the utility model is further described now.These accompanying drawings only illustrate basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.

A kind of domestic central solar heating system as shown in Figure 1 and Figure 2 is for indoor floor heating provides heat to the house.Comprise heat collector 1, water tank 2 and be arranged on the indoor ground heating floor in room 3, the pipeline that leads to ground heating floor 3 at water tank 2 is provided with supply-water pump 5, is provided with first controller 6 that control supply-water pump 5 starts or cuts out between supply-water pump 5 and the ground heating floor 3; Pipeline between heat collector 1 and the water tank 2 is provided with water circulating pump 7, be provided with electric heater 8 in the water tank 2, electric heater 8 can be when continuous cloudy sunlight be not enough heating water tank 2 inner cold waters, be provided with second controller 9 that control water circulating pump 7 moves between electric heater 8 and the water circulating pump 7.Be connected with the cold water pipe 4 that injects cold water to water tank 2 on the water tank 2, the cold water in the water tank 2 leads to ground heating floor 3 after absorbing the heating of sunshine heat by heat collector 1, gives the indoor heating service in room.

Described water tank 2 is gone back pipeline and is connected with shower 10, can satisfy people simultaneously in heating and have a bath and live with the requirement of hot water.
