Abstract
The present invention relates to a solar water heater. It can be extensively used in the field of plate solar water heater technology. It is characterized by that it mainly utilizes temperature difference to control circulating pump so as to make the water implement circulation flow. Said solar water heater mainly includes the following several portions: water tank, circulating pump, heat-collecting plate, heat-insulating water tank and pipeline, etc. Said invention also provides their connecting mode and its working principle.
Description
The present invention is a kind of solar water heater, and it is mainly used in plate solar heat hydrophone technical field.
Known, the plate solar heat hydrophone is stable, reliable, the safest water heater of present performance.But owing to be subjected to geographical conditions and climatic effect, classic flat-plate solar water heater's thermal-arrest plate unstable properties at a lower temperature, usually can't normally use its spalling after water congeals into ice in the thermal-arrest plate circulating line.Though part plate solar heat hydrophone has been taked freeze proof measure (mainly containing built-in elastic method, electrical heating method, anti-icing fluid method at present), these methods make plate solar heat water heater structure complexity, cost height, the more high shortcoming of failure-frequency.
For overcome existing plate solar heat hydrophone unstable properties, not freeze proof, the scope of application is restricted, freeze proof cost height, the more high shortcoming of failure-frequency, the present invention proposes a kind of solar water heater, not only solve the freeze proof problem of plate solar heat hydrophone effectively, and enlarged the use region of plate solar heat hydrophone.
The technical solution adopted for the present invention to solve the technical problems is: when thermal-arrest plate installation site was higher than attemperater, it was poor to form certain altitude.Use a threeway in the thermal cycle pipeline, the other end of threeway is connected with attemperater by check valve, mixes water problems as not considering the circulation time water, and thermal-arrest plate delivery port can directly link to each other with the attemperater upper end.Use a circulating pump in the cold circulation line, the water circulation in the temperature difference (two temperatures sensor poor) the control solar water heater when the temperature difference reaches when setting starting value, starts circulating pump work, and the gas in the thermal-arrest plate is pushed into the attemperater internal upper part.Set when stopping to be worth when the temperature difference reaches, circulating pump quits work.When stopping, water in cold circulation line and the thermal-arrest plate enters attemperater owing to deadweight produces reverse circulation, the gas of attemperater internal upper part is shifted onto in thermal-arrest plate and the circulation line through check valve, and the water in the thermal-arrest plate is drained in the attemperater, realizes the freeze proof effect of solar water heater.When the installation site of thermal-arrest plate is lower than attemperater, small-sized attemperater is installed below the thermal-arrest Board position, small-sized attemperater also can have delivery port for using simultaneously.The thermal cycle of thermal-arrest plate is connected with attemperater through small-sized attemperater.Use a circulating pump in the cold circulation line, during the circulating pump starting, the gas in the thermal-arrest plate is pushed in the small-sized attemperater.When circulating pump stops, utilizing the pressure reduction of attemperater and thermal-arrest plate and small-sized attemperater that the gas in the small-sized attemperater is oppositely added in the thermal-arrest plate, the water in the thermal-arrest plate is discharged in the attemperater along cold circulation line.
The invention has the beneficial effects as follows: system self produces Negative Pressure Difference when utilizing circulating pump to quit work, and in the thermal-arrest plate, the water in the thermal-arrest plate follows endless tube road Jiang Shui and is discharged in the attemperater, thereby reaches the freeze proof purpose of solar water heater with gas make-up.
The invention will be further described below in conjunction with accompanying drawing and concrete utilization and embodiment:

Concrete utilization and embodiment:
1, thermal-arrest plate installation site is higher than attemperater.When the difference of thermal-arrest plate temperature and water tank temperature reaches starting value, circulating pump (6) startup work, water in the water heater begins circulation, and the gas in the thermal-arrest plate is pushed in the attemperater, and attemperater internal upper part gas capacity space is more than or equal to the volume space of thermal-arrest plate and circulation line.When the temperature difference reaches when stopping to be worth, circulating pump quits work, water in cold circulating line and the thermal-arrest plate enters attemperater owing to deadweight produces reverse circulation, the interior water level of water tank this moment raises, attemperater top check valve is backed down in the loading pressure increase, thermal-arrest plate and attemperater form a linker, gas is discharged to the water in the thermal-arrest plate in the attemperater through cold circulation line through thermal cycle, thereby the water in emptying thermal-arrest plate and the circulation line, realize the function of automatic emptying, thereby reached freeze proof effect.
2, thermal-arrest plate installation site is lower than attemperater.Small-sized attemperater is installed below the thermal-arrest plate, when the difference of thermal-arrest plate temperature and water tank temperature reaches starting value, circulating pump starts, water in the water heater begins circulation, gas in the thermal-arrest plate is pushed in the small-sized attemperater in below, and the spatial content in the small-sized attemperater is more than or equal to the capacity of thermal-arrest plate and circulation line.When the temperature difference reaches when stopping to be worth, circulating pump quits work, utilize the pressure reduction of attemperater and small-sized attemperater that the gas make-up in the small-sized attemperater is arrived in the thermal-arrest plate, the water in the thermal-arrest plate is shifted onto in the attemperater through cold circulation, realize the automatic air emptying function of thermal-arrest plate.
