Abstract
A testing and controlling instrument for radiation refrigeration of flat plate solar collectors comprises a sensor, an output interface, a man-machine interface, a host part and a power source and is used for controlling the flat plate solar collectors for radiation refrigeration at night. The man-machine interface comprises an acoustic-optic display, a key and a touch screen. The output interface comprises network connection equipment and mobile storage equipment. The instrument is characterized by comprising a radiation testing instrument and starting the radiation refrigeration mechanism when the radiation intensity is lower than 100w/m2 or comprising a water tank temperature sensor and a collector outlet water temperature sensor and starting the radiation refrigeration mechanism when the collector outlet water temperature is lower than the water tank temperature. The instrument has the following beneficial effects: the instrument provides applicable testing and controlling means for obtaining plenty of cold energy at night by utilizing the flat plate solar collectors in the inland areas; and the obtained cold energy can be used for air conditioning, assisting the air conditioning plants to work in the day or releasing the residual heat energy of the flat plate collectors in the day. The invention gives an embodiment in combination with the drawing.
Description
Technical field
The present invention relates to flat plate collector radiation refrigeration measurement and control instrument.
Background technology
The situation that solar irradiation is strong for heat supply in summer water load is little for fear of too high empty solarization of solar heat-collection actuator temperature, need be cooled off the hot water of solar heat collector output.This usually needs to build special cooling device.In addition, to the hinterland, the radiation refrigeration power of flat plate collector does not does not almost develop and utilize.
Summary of the invention
The objective of the invention is to provide flat plate collector radiation refrigeration measurement and control instrument.
The present invention solves the technical scheme that its technical problem is taked: form a flat plate collector radiation refrigeration measurement and control instrument with sensor, output interface, man-machine interface, host machine part and power supply, be used for controlling by the flat plate collector of heat loss through radiation refrigeration night.Man-machine interface comprises acousto-optic demonstration, button and touch-screen.Output interface comprises network access device and movable storage device.Use the irradiation tester and work as irradiation intensity and be lower than 100 watts/m
2Shi Qidong radiation refrigeration mechanism; Perhaps use water tank temperature sensor and heat collector leaving water temperature sensor and when the heat collector leaving water temperature is lower than water tank temperature, start radiation refrigeration mechanism.
As concrete application design, radiation refrigeration measurement and control instrument of the present invention can also and the integrated making of solar water-temperature water-level measurement and control instrument, can also be electrically connected with indoor temperature transmitter with one, can also contain one 1～5 ℃ of environment temperature made the antifreeze program of response and when environment temperature enters 1～5 ℃ the antifreeze program of unimpeded access, can also adopt while observing and controlling to control the output interface of object more than two, can also enter duty 4 of local time 20 points～next day.
Beneficial effect of the present invention comprises: provide the observing and controlling means that are suitable for for utilize flat plate collector to obtain a large amount of cold energy at night in the hinterland.Resulting cold energy can be used for air-conditioning, perhaps is used for auxiliary aircondition work on daytime; Perhaps being used for the dialogue sky unnecessary heat energy of flat plate collector discharges.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a single flow flat plate collector nocturnal radiation refrigerating plant configuration diagram.
1. flat plate collectors among the figure; 2. control device; 3. circulating pump; 4. adiabatic water tank.
The specific embodiment
Fig. 1 embodiment, Fig. 1 embodiment will form a flat plate collector nocturnal radiation refrigerating plant with flat plate collector 1 and control device 2 that cover-plate glass, tube plate absorber and heat insulation layer arranged stacked are made in case type container.Control device 2 guarantees to make heat collector that water output is arranged at fine night.By being connected with the temperature sensor heat exchange of control device 2 from the water of heat collector output and the water of input heat collector, control device detects and the flow of circulating pump 3 is controlled the duty of refrigerating plant, so that refrigerating plant is according to the work of setting that requires.Cooled water is stored in the adiabatic water tank 4.
As the radiation cooling device of Fig. 1 embodiment, maximum heat dissipation capacity can reach 400 watts/m
2Lowest refrigerating temperature is lower than 2 ℃ of environment surface temperatures.
