Abstract
The invention discloses a transcritical carbon dioxide solar water heater, which is characterized in that by utilizing the physical thermodynamics property of carbon dioxide, the water heater absorbs heat generated by solar radiation and air with a temperature above 10 DEG C below zero through heat pump equipment. A large amount of hot water can be produced for generating electricity or other purposes. In a condition with higher air humidity, the water heater also can absorb moisture in the air for people to use. The transcritical carbon dioxide solar water heater has the advantages of wide application range, simple structure, safety, reliability, environmental protection, energy saving and low production cost, and thus has favorable popularization value.
Description
Technical field:
The present invention relates to utilize the physical thermodynamics character of carbon dioxide,, absorb the heat of solar radiation and environment temperature by heat-pump apparatus.Produce the technical field of a large amount of hot water.
Background technology:
At present not only cost height, the thermal efficiency are low for solar water heater, and can only absorb the heat of solar radiation.Therefore, when not having sunlight, just there is not hot water to produce.This water heater can not satisfy people to the hot water requirement.As carrying out power generation application with the hot water that this solar water heater produces, that is just more difficult.Unstable because the cost of hot water is high, can not produce the chronic of hot water.Therefore, it is lower to be badly in need of a kind of cost, thermal efficiency height; Not only can directly utilize the heat of solar radiation to produce hot water, and can utilize environment temperature (heat that comprises air and various water), it is for people to use to produce a large amount of hot water, or is used for generating.The present invention invents for this purpose.
Summary of the invention:
The present invention studies the theory that draws " utilize the physical thermodynamics character of operation material, by heat-pump apparatus, low-temperature heat source can be used as high temperature heat source " for many years according to me; Utilize the physical thermodynamics character of carbon dioxide, by heat-pump apparatus, absorb solar radiation and air and be higher than the subzero heat of air more than 10 ℃, it is for people to use to produce a large amount of hot water, or is used for generating.This water heater can also be when air has certain humidity, and it is for people to use to absorb airborne moisture.
The present invention is that I build the absorption solar radiation that the solar power plant of arid areas such as desert designs and the endothermic system of the heat in the air themperature in.
The specific embodiment:
Carbon dioxide in the low pressure CO 2 liquid storage cylinder is compressed into supercritical carbon dioxide liquid by compressor.The heat that is produced is absorbed by heat exchanger, becomes temperature required hot water.Behind heat exchanger, low-temperature carbon dioxide liquid, be ejected into the large tracts of land heat dump that is positioned on the roof through vaporizer, become the carbon dioxide of low temperature, low pressure, to absorb solar radiation and airborne heat.Absorb the carbon dioxide behind the heat and be back in the low pressure CO 2 liquid storage cylinder so continuous circulation.
The hot water temperature is realized by control cold water influx.Therefore, be provided with a cover by temperature controlled automatic flow switch.The hot water temperature is too high, then strengthens the cold water influx automatically, otherwise, then reduce the cold water influx.
The heat dump bottom is provided with condensate water recovery device.Airborne steam, the condensed water that forms on the heat dump surface can flow in the condensate collector automatically, and is for people to use.
Accompanying drawing is a critical-cross carbon dioxide solar water heater schematic diagram.
