The transcritical carbon dioxide solar air conditioning water heater disclosed by the invention is applicable to the households, hotels, various types of enterprises, factories and arid regions. Due to the wide application range, relatively simple structure, safety, reliability, environmental friendliness, energy consumption and relatively low manufacturing cost, the transcritical carbon dioxide solar air conditioning water heater has a good market prospect.
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 new energies that a large amount of hot water and cold air are used for air-conditioning, refrigeration, heat supply and generating.
Background technology:
Have ample evidence to prove: the problem that constantly rise in global warming, sea level, the desert constantly enlarges, diastrous weather constantly increases and reinforcement, a large amount of species extinctions, a large amount of carcinogenic substance contaminated air, food and water sources etc. jeopardize environment for human survival all has direct relation with the method that human combustion fuel obtains the energy.Whole world minimum every day has millions of people to fall ill because of environmental pollution at present, and die from cancer person because of environmental pollution and exceed 7,000,000 people every year.And in China, singly be because of environmental pollution, just produce lopsided children per 30 seconds!
Coal is the main force of the present energy of China, also is the main source of making China's environmental pollution.The coal of China about 60% is used for generating at present.The heating boiler and the Industrial Boiler that are used for dispersed supply of heating in addition have more than 50 ten thousand, annual more than 400,000,000 ton of the coal that consumes.The heat-supplying mode of this dispersion has brought great pressure to environment.The world enumerated of the World Bank pollutes in 20 the most serious cities according to calendar year 2001, and China occupies 16.The loss that China's atmosphere pollution is made has accounted for 3%～7% of GDP.According to the statistics made by the departments concerned, thousands of coal miner death are made because of the exploitation colliery in the past every year on average by China.
At present not only cost height, the thermal efficiency are low for solar water heater, not only do not have air conditioning function, 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 and require.As generating electricity 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), produce the solar-powered air conditioner and water heater that a large amount of hot water can supply air-conditioning, refrigeration, heat supply or power generation application simultaneously, 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,, absorb solar radiation and air and be higher than the subzero heat of air more than 10 ℃, produce the solar-powered air conditioner and water heater that a large amount of hot water and cold air are used for air-conditioning, refrigeration, heat supply or power generation application by heat-pump apparatus.This water heater can also absorb the people use of airborne moisture for the arid area when air has certain humidity.
The specific embodiment:
Carbon dioxide in the low pressure CO 2 liquid storage cylinder is compressed into by compressor in the process of supercritical carbon dioxide liquid, and the heat that produces is absorbed by the cold water of heat exchanger, becomes temperature required hot water.
Behind heat exchanger, become low-temperature carbon dioxide supercritical carbon dioxide liquid,, be ejected into the heat dump that is positioned at the roof, become the carbon dioxide of low-temp low-pressure, be higher than the subzero heat of air more than 10 ℃ in order to absorb solar radiation and temperature through vaporizer.
The carbon dioxide that has absorbed heat in the heat dump is back in the low pressure CO 2 liquid storage cylinder, and begins to carry out the circulation of a new round.
The heat dump bottom is provided with two air ejectors, and one is discharged into the heat dump bottom with indoor air, utilizes the heat of this part air to produce hot water; Another air ejector is equipped with by temperature controlled automatic flow gauge tap, when indoor temperature is too high, opens the switch that leads to the heat dump bottom, and the cold air with the heat dump bottom is drawn into indoor as required; When winter indoor temperature cross when low, then close this switch so that indoor temperature meets our requirement.
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 hot water that produces flows into the heat accumulation pond and a pipeline that leads to the hot water heat exchanger by temperature controlled automatic flow gauge tap is housed by high-efficiency insulated pipeline is arranged, when winter indoor temperature cross when low, make the heating purposes in order to cold air in the heating clamber as required; When indoor temperature reaches set temperature, then close this pipeline automatically; The water that loses heat in the hot water heat exchanger then is back to the storage water cooling pond.
The heat dump bottom is provided with condensate water recovery device.The condensed water that rainwater and airborne steam form on the heat dump surface can flow in rainwater and the condensate collector automatically and flow to the storage water cooling pond after filtering, and this water can be used as the water supply purposes.
Accompanying drawing is a critical-cross carbon dioxide solar-powered air conditioner and water heater schematic diagram.
