Description
Technical field
The present invention relates to a kind of flat plate solar water heater of frequency conversion working medium circulation, particularly the flat plate solar water heater of the small-sized solar panel controlled medium of a kind of usefulness circulating pump frequency conversion frequency.
Background technology
Add the flat plate solar water heater that working medium circulating pump and circulating line and computer controller consist of by solar heat-collection plate with the boiler of working fluid heat exchanger, usually by computer controller according to setting the fixed frequency operation of temperature difference controlled medium circulating pump with 50Hz.The startup of working medium circulating pump and stop only deciding and not contacting directly with the power of solar energy by the temperature difference between solar heat-collection plate and water tank, thereby the circular flow of working medium and solar energy is strong and weak and asynchronous.The power of the circular flow that a kind of comparatively ideal working medium circulation mode is working medium and solar energy is synchronous: solar radiation is stronger, and the flow of working medium circulation then should be larger; Solar radiation weakens, and the flow of working medium circulation is corresponding weakening then.Like this, the heat absorption efficiency of solar thermal collector can be improved, the energy consumption of working medium circulating pump can be saved again.For realizing this purpose, circulating pump can adopt VFC, and computer controller is connected to frequency-variable module by relay delivery outlet and analog output mouth, and the output of frequency-variable module is connected to the working medium circulation pump motor; The analog quantity input of computer controller is also connected to a small-sized solar cell panel.Then the voltage of solar panel just can input control voltage to computer controller, the computing by computer controller just can make the intensity of illumination of the output frequency of frequency converter and solar energy proportional.
Through retrieval, in the existing solar water heater, also do not use the invention of VFC working medium circulation pump operation, especially there is not the external small-sized solar cell panel of computer controller to control the invention of the frequency conversion frequency of output.
Summary of the invention
The purpose of this invention is to provide a kind of flat plate solar water heater that adopts conversion system controlled medium circulating pump.Computer controller removes to control the output frequency of frequency converter according to the output voltage of solar panel, the running frequency that makes working medium circulating pump strengthens with the increase of solar illuminating intensity, reaches the working medium circulating pump operating frequency and solar illuminating intensity has the purpose of proportional relation.
The objective of the invention is to realize by the following method:
A kind of flat plate solar water heater of frequency conversion working medium circulation, it comprises computer controller, small-sized solar cell panel, boiler, flat-plate solar collector, working medium circulating pump, connecting pipe.It is characterized in that: the output interface of the computer controller of this flat plate solar water heater links to each other with the input interface of frequency-variable module, the analog input interface of computer controller links to each other with the Voltage-output interface of small-sized solar cell panel, and the output interface of frequency-variable module links to each other with the motor of working medium circulating pump.
Use exchanging the flat plate solar water heater that drives circulating pump with fixed frequency and comparing of the present invention and routine, can improve the hot water productive rate of flat type solar heat collector, and the operation energy consumption of reduction working medium circulating pump.
Description of drawings
Fig. 1 is the embodiments of the invention schematic diagram.
The specific embodiment
1 embodiment is for a more detailed description to the present invention by reference to the accompanying drawings.
Structure of the present invention and operation principle are as follows:
A kind of flat plate solar water heater of frequency conversion working medium circulation is made of computer controller 1, frequency-variable module 2, small-sized solar cell panel 3, boiler 4, flat-plate solar collector 5, working medium circulating pump 6, connecting pipe 7.The relay delivery outlet of computer controller 1 links to each other with the analog quantity input of frequency-variable module 2, the analog output mouth of computer controller 1 links to each other with the analog quantity input of frequency-variable module 2, the analog quantity input of computer controller 1 links to each other with the voltage output end of small-sized solar cell panel 3, and the ac output end of frequency-variable module 2 links to each other with the motor of working medium circulating pump 6.Boiler 4 links to each other with flat-plate solar collector 5 and working medium circulating pump 6 by pipeline 7.
When microcomputer controller 1 was connected the AC power of frequency converter 2 and exported the control voltage of a setting, frequency converter 2 was just by the low-limit frequency operation of setting.Because the analog quantity input of computer controller 1 links to each other with the Voltage-output interface of small-sized solar cell panel 3, the voltage of solar panel 3 just can be input to microcomputer controller 1, if the intensity of illumination of the sun increases, the output voltage of solar panel 3 just increases thereupon, then microcomputer controller 1 just can be by the control program of setting, through improving the control voltage of supplying with frequency-variable module 2 after the computing, the output frequency of frequency-variable module 2 is increased, the rotating speed of working medium circulating pump 6 is with regard to corresponding increase, the circular flow of working medium also will increase with the increase of solar energy intensity, realizes thus operating frequency and the proportional relation of solar illuminating intensity of working medium circulating pump 6.
