Abstract
The invention provides a solar heat-collecting system capable of measuring the solar hot water yield. The solar heat-collecting system is composed of solar heat-collecting panels, a heat-collecting panel water inlet main pipe, a heat-collecting circulating pump, a heat-collecting water tank, a heat storage water tank, a heat-collecting panel water outlet main pipe, a two-position three-way valve, a flowmeter, a heat storage water tank water inlet pipe, a heat-collecting water tank temperature sensor and a heat-collecting water tank water inlet electromagnetic valve. The solar heat-collecting system is characterized in that the heat-collecting panel water outlet main pipe is provided with the two-position three-way valve, a first outlet of the two-position three-way valve is connected to an upper water inlet of the heat-collecting water tank, and a second outlet of the two-position three-way valve is connected to an upper water inlet pipe of the heat storage water tank through the flowmeter. By means of the system, the solar hot water yield of the solar heat-collecting system can be measured.
Description
Technical field
The present invention relates to a kind of solar thermal collection system, particularly a kind of solar thermal collection system measuring solar water productive rate.
Background technology
The solar thermal collection system be made up of solar thermal collector and heat collection water tank and hot water storage tank, after heat collection water tank reaches design temperature, adopts endless form that the hot water in heat collection water tank is sent into hot water storage tank usually.Hot water amount's metering method is measured by hot water storage tank efferent duct usually; Or carry out a point metering by the pipeline of registering one's residence of each user, then gather.This metering method can only obtain total hot water amount and cannot obtain the hot water productive rate of solar thermal collector, thus cannot the heat that obtains from solar energy of accurate count.
For obtaining the hot water productive rate of solar thermal collector, can adopt and install two position three-way valve additional at the output of collecting plate circulating-heating pipe and be connected respectively to heat collection water tank and hot water storage tank, this pipeline road being connected to hot water storage tank also will there is flowmeter, by two position three-way valve, collecting plate efferent duct is connected to hot water storage tank when heat collection water tank water temperature reaches design temperature, the hot water of heat collection water tank is sent to hot water storage tank, and measured by flowmeter, reach the object measuring hot water productive rate.
Through retrieval, in the invention of existing solar thermal collection system, the invention of the solar thermal collection system of also not identical with the present invention hot water measured productive rate.
Summary of the invention
The object of this invention is to provide a kind of solar thermal collection system measuring solar water productive rate, this system installs a two position three-way valve additional on total outlet pipe of solar heat-collection plate, the primary outlet of two position three-way valve is connected to the heating water return outlet of heat collection water tank, and second outlet of two position three-way valve is connected to the top water inlet of hot water storage tank by flowmeter.
The object of the invention is to realize by the following method:
Measure a solar thermal collection system for solar water productive rate, it is characterized in that:
The lower end delivery port of hot water storage tank is connected to heat collector water inlet manifold by heat cycles pump and is connected to solar heat-collection plate, the outfall sewer of solar heat-collection plate is equipped with two position three-way valve, the primary outlet of two position three-way valve is connected to heat collection water tank top water inlet, and second outlet of two position three-way valve is connected to the top water inlet pipe of hot water storage tank by flowmeter.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention schematic diagram;
Detailed description of the invention
1 embodiment is for a more detailed description to the present invention by reference to the accompanying drawings:
A kind of solar thermal collection system measuring solar water productive rate is by solar heat-collection plate 1, collecting plate water inlet manifold 2, thermal-arrest circulating pump 3, heat collection water tank 4, hot water storage tank 5, collecting plate outfall sewer 6, two position three-way valve 7, flowmeter 8, hot water storage tank water inlet pipe 9, heat collection water tank temperature sensor 10, heat collection water tank entering water electromagnetic valve 11 is formed.The lower end delivery port of heat collection water tank 5 is connected to collecting plate water inlet manifold 2 by thermal-arrest circulating pump 3 and is connected to solar heat-collection plate 1; The outfall sewer 6 of solar heat-collection plate 1 is equipped with two position three-way valve 7, and the primary outlet of two position three-way valve 7 is connected to the top water inlet of heat collection water tank 4, and second outlet of two position three-way valve 7 is connected to the top water inlet pipe 9 of hot water storage tank 5 by flowmeter 8; Temperature sensor 10 and entering water electromagnetic valve 11 heat collection water tank be also equipped with.
During system cloud gray model, when the water temperature in solar energy heating water tank is lower than design temperature, solar heat-collection plate outfall sewer 6 is connected to heat collection water tank top water inlet by the primary outlet of two position three-way valve 7, by the water in collecting plate heating heat collection water tank when making thermal-arrest pump operating cycle.When the water temperature in heat collection water tank reaches design temperature, collecting plate outfall sewer is connected to hot water storage tank top hot water inlet pipe 9 by second outlet by two position three-way valve energising switching, circulating pump is made to be pressed onto in hot water storage tank 5 by the hot water in heat collection water tank 4, flowmeter 8 works simultaneously, the hot water flow of recorded stream superheated water water inlet pipe 9, reaches the object measuring solar water productive rate.
