Description
Technical field:
The invention belongs to renewable energy utilization engineering field more particularly to a kind of solar energy and air energy phase-change heat-storages
Central air conditioner system.
Background technique:
Since the industrial revolution, since mankind's activity discharges a large amount of greenhouse gases, so that atmospheric greenhouse gas is dense
Degree sharply increases, and as a result causes the greenhouse effects in atmosphere to be increasingly enhanced, scientists are greenhouse caused by this human activity
Effect is known as " greenhouse effects of enhancing ", this is exactly the greenhouse effects that global environment scientists are paid close attention to and worried.With
Atmospheric warming effect constantly aggravates, and global average temperature will also increase year by year, eventually leads to global warming, generates a system
The present uncertain global climate problem of science of column.
The mankind enter after industrialization, and a large amount of exploitations use the subsurface mineral energy.In the past 30 years, coal, oil and natural gas
The burning of equal fossil fuels about discharges 5,000,000,000 tons of CO every year2, the National People's Congress is allowed to be shocked.In addition, CO in atmosphere2Increase there are also one
A main cause is exactly that virgin forest trees are largely cut down as fuel burning.1.5kg can be absorbed in every cubic metre of forest
The CO of left and right2, and then reduce greenhouse effects.And fall trees, being Atmospheric CO originally2Absorption " library " devastatingly become
One Atmospheric CO2Discharge come " source ".Estimate according to the World Food Programme, there are about the trees of 1,200,000,000 m3 every year is burned by felling, this
A little trees burnings generate a large amount of CO2, Atmospheric CO can be made every year2Concentration at least increases 0.4ppm；CH in atmosphere4The increase of content
Also very rapidly, mainly due to the continuous expansion of global range Monitoring of Paddy Rice Plant Area and quickly resulting in for animal husbandry.
The enteron aisle of people and plant-eating animal, excrement, the wet depression in marsh, submerged weir flow, combustion of fossil fuel etc. are all the important next of atmospheric CH_4
Source.In addition, the mankind when extracting natural gas with coal, can also discharge CH into atmosphere4；N in atmosphere2The increase of O is mainly farmland
The increase of the investment and animal excrements quantity of chemical nitrogen fertilizer causes, and the increase also burned with combustion of fossil fuel and biomass has
Relationship.N in atmosphere2O not only has greenhouse effects, can also destroy ozone layer, makes the solar ultraviolet for reaching earth surface
Intensity increases, and damages to skin.Greenhouse gases, which increase, brings endless trouble, and will bring devastating disaster to the mankind, is this person
Class must plan Future New Energy Source effective use early.
Currently, solar energy utilization also be not it is very universal, using solar power generation, there is also at high cost, transfer efficiency is low
Problem, but solar battery is applied in terms of providing the energy for artificial satellite.Solar energy is solar interior or table
The black mole in the face energy that continuously nuclear fusion reaction process generates.Average intensity of solar radiation on Earth's orbit is 1,
369w/㎡.The Zhou Changwei 40,000km of terrestrial equator, so as to calculate, the energy that the earth obtains is up to 173,000TW.?
Typical peak intensity on sea level is 1kw/m2, and the annual radiation intensity of earth surface certain point for 24 hours is 0.20kw/ ㎡,
It is equivalent to the energy of 102,000TW, the mankind rely on these energy and survive, including the renewable of every other form
The energy (except geothermal energy resource), although solar energy resources total amount is equivalent to more than 10,000 times of the energy that the present mankind are utilized,
But the energy density of solar energy is low, and it varies in different localities, and becomes because of when, this be develop and use solar energy face mainly ask
Topic.These features of solar energy can be such that its effect in entire comprehensive energy system is subject to certain restrictions.Although sun spoke
The energy for being mapped to earth atmosphere is only 1st/2200000000th of its total radiation energy, but has been up to 173,000TW, that is to say, that too
It being irradiated to tellurian energy positive each second and is equivalent to 5,000,000 tons of coals, the energy per second for being irradiated to the earth is then 499,400,
00,000 is burnt.Tellurian wind energy, water energy, ocean thermal energy, wave energy and biomass energy are all derived from the sun；Even ground
Fossil fuel (such as coal, petroleum, natural gas) on ball has stored the solar energy to get off since being also basically time immemorial, so
Range included by the solar energy of broad sense is very big, and the solar energy of narrow sense is then limited to the photo-thermal of solar radiant energy, photoelectricity and photochemical
The direct conversion learned.
Solar energy is both non-renewable energy and renewable energy.It is resourceful, not only can freely use, but also without transporting,
To environment without any pollution.A kind of new lifestyle is created for the mankind, so that society and the mankind is entered one and energy saving subtracts
The epoch of of low pollution.
Air can be wind energy, solar energy, after tide energy by human development using extensive new energy, its not only Energy Efficiency Ratio
High and low-carbon environment-friendly, carbon dioxide will not be discharged after utilization will not more generate pernicious gas, it is important it be it is reproducible, have very
High utility value is the domestic emphasis new energy for actively encouraging development and utilization.The origin of heat of air energy heat pump is exactly for we
The air all having to, and the quality as a kind of its degree of power conservation of energy-conserving product is all closely related with COP value Energy Efficiency Ratio.Due to
Most air energy heat pump design normal working temperature is at 0-40 DEG C in the market.Therefore the south relatively high in environment temperature, it is empty
Gas energy heat pump often has excellent performance.And winter temperature only has -10 DEG C of north city air energy heat pump to be extremely difficult to design
The effect of middle anticipation.If temperature is that -20 DEG C of units even cannot all start.Especially existing air energy heat pump defrost still uses
Inverted running defrost, this just seriously affects the experience of user, and expends many times on defrost, and needs to stop system
Thermal technology makees.
If we can combine solar energy with air using evaporimeter frosting can be effectively prevented, can prevent completely
Evaporator copper pipe is by swollen bad, it is often more important that heat pump main frame Energy Efficiency Ratio can also greatly improve, especially with phase-change thermal storage mode
Comprehensive energy efficiency ratio is more allowed to greatly improve.It is understood that not only Energy Efficiency Ratio is low for existing wind-cooling type heat pump unit, but also defrost is also one
Hang-up, resultant heat source tower just come into being, but can still encounter anti-icing fluid freezing point temperature and move up problem, that is,
It says that its concentration is accordingly thinning after steam constantly condenses and incorporates anti-icing fluid in air, then its freezing point temperature will be shifted up, surpasses
Crossing apparent freezing point relevant temperature is that will result in the generation of icing accident, so must try every possible means solves the problems, such as this, certainly with concentration
Anti-icing fluid method.
