Describe the supply unit and the refrigeration/thermic devices of low-carbon (LC) air-conditioning of the present invention below in detail.
Supply unit:
Supply unit can be a D.C. regulated power supply, and it is made up of power transformer, rectification circuit, filter circuit and mu balanced circuit four parts.
Wherein:
(1) power transformer: be step-down transformer, the alternating voltage that it becomes to suit the requirements with electrical network 220V AC voltage conversion, and give rectification circuit, the variation of transformer is determined by the secondary voltage of transformer.
(2) rectification circuit: utilize asymmetrical circuit element, the sinusoidal ac of 50Hz is transformed into the direct current of pulsation.

(4) mu balanced circuit: the function of mu balanced circuit is the dc voltage stability that makes output, and the variation with ac grid voltage and load does not change.
Refrigeration/thermic devices:
The material of the refrigeration/backing in refrigeration/thermic devices thermoelectric semiconductor cooling assembly, Peltier.Because the thermoelectric semiconductor cooling assembly is divided into the two sides, when electric current when the thermocouple, one of them node loses heat and another node absorbs heat, the thermoelectric semiconductor refrigeration train just plays conductive force, itself can not produce cold.The semiconductor bulk cooling assembly is made up of N-type semiconductor and P-type semiconductor.N type material has unnecessary electronics, and subzero temperature difference electromotive force is arranged.The P-type material electron deficiency has positive thermoelectric force; When electronics passed node to the N type from the P type, the temperature of node reduced, and its energy must increase, and the energy that increases is equivalent to the energy that node consumes.On the contrary, when electronics when the N type flow to P-type material, the temperature of node will raise.Semiconductor element can satisfy user's requirement with various method of attachment.A P-type semiconductor element and a N-type semiconductor element are coupled to a pair of thermocouple, connect dc source after, the transfer that will produce the temperature difference and heat in the joint.Superincumbent joint, the sense of current are from N to P, and temperature descends and heat absorption, Here it is cold junction; And a joint below, the sense of current is from P to N, temperature rises and heat release, is the hot junction therefore.Therefore be that the conductor refrigeration sheet is formed by mutual arrangement of the particle of many N types and P-type semiconductor; form a complete line and be connected with general conductor between the N/P; normally copper, aluminium or other metallic conductors; pick up as sandwich biscuits by two potsherds at last, potsherd must insulate and heat conduction good.
Double-deck cooling piece is to have adopted bottom chip that the principle that last synusia absorbs heat is made into, so for the huyashi-chuuka (cold chinese-style noodles) that better makes the upper strata has a minimum temperature, two-layer up and down is to have adopted the particle that does not wait right.
In addition, low-carbon (LC) air-conditioning of the present invention can also comprise attemperating unit and remote control device, further can also comprise being provided with reporting to the police and automatic error correction device.
The refrigeration test result:
With reference to figure 4, be refrigerating capacity Q, input power W, the coefficient of refrigerating performance ε of low-carbon (LC) air-conditioning according to an embodiment of the invention change curve with electric current I.This experimental study water-cooling system under different electric currents, the variation tendency of the refrigerating capacity Q of thermoelectric pile, input power W and coefficient of refrigerating performance ε, simultaneous verification is with the applicability of constant power state as duty.In room temperature is that chilled-water flow is under the experiment condition of 36kg/h in 30 ℃, cold junction coil pipe, try to achieve refrigerating capacity Q by surveying the cold junction import and export temperature difference, survey input current, input voltage calculates input power W, refrigerating capacity Q, input power W, coefficient of refrigerating performance ε are with the variation of electric current I as shown in Figure 4.
As can be seen from Figure 4, under the water-cooled situation, the service behaviour of thermoelectric pile and the description basically identical in the theory, the input current of its refrigerating efficiency and thermoelectric pile is closely related.Electric current is too little, and refrigeration work consumption is not enough; Electric current is too big, and Joule heat increases, and increases the weight of cooling load.At Q
MaxState, maximum cooling capacity can reach 180W, and the refrigerating capacity 30W of each thermoelectric pile is 60% of maximum cooling capacity, but the coefficient of refrigerating performance ε of this moment is very little; And at ε
MaxElectric current I O during state is very little, can't measure Q, ε value under this electric current in the experiment, so can't determine ε
MaxElectric current I o during state, on curvilinear trend, refrigerating capacity Q is very little under this state.Press constant power state design theory, the intersection point E that gets curve Q and W is as the ideal operation state, under this state, and IE=219A, ε=1, QE=170W, the refrigerating capacity of each thermoelectric pile is 55% of a maximum cooling capacity; If get I=216A, Q=155W then, ε=112, at this moment the refrigerating capacity of each thermoelectric pile is 50% of a maximum cooling capacity just, when getting I=210A, and Q=120W then, ε=1165, the refrigerating capacity of each thermoelectric pile is 40% of a maximum cooling capacity, and this is a kind of design of tending to obtain big coefficient of refrigerating performance, experimental result and design basically identical.
With reference to figure 5, be that cool storage medium and warm end temperature difference are respectively under Δ T1=1 ℃, Δ T2=3 ℃, the Δ T3=5 ℃ situation, refrigerating capacity Q, input power W, coefficient of refrigerating performance ε are with the electric current I change curve.This experimental study air cooling system under different current/voltages, refrigerating capacity Q, the input power W of thermoelectric pile, the variation tendency of coefficient of refrigerating performance ε when making the identical difference variation of the water generates of homogenous quantities.Experiment records at cool storage medium and warm end temperature difference and is respectively under Δ T1=1 ℃, Δ T2=3 ℃, the Δ T3=5 ℃ situation, and Q, W, ε are with the electric current I change curve, as shown in Figure 5.
As can be seen from the figure, under same temperature difference T, coefficient of refrigerating performance ε, refrigerating capacity Q, input power W test similar with the electric current I variation tendency to water-cooled.There is Q when being system works
MaxState, the operating current Im under this state is about 310A; And because at ε
MaxElectric current I O during state is very little, can't measure the pairing refrigerating capacity Q of this electric current, coefficient of refrigerating performance ε etc. in the experiment, so can't determine ε
MaxElectric current I O during state; Input power W constantly increases with the increase of electric current I, does not have maximum.Under same current/voltage, refrigerating capacity Q, coefficient of refrigerating performance ε reduce with the increase of temperature difference T; Input power W remains unchanged, and is irrelevant with temperature difference T.Hence one can see that, improve system's refrigerating efficiency and increase refrigerating capacity Q, must reduce cold and hot end temperature difference T as far as possible, promptly carries out hot-side heat dissipation
The superiority of water-cooling system just has been described from above-mentioned experimental analysis.With regard to the hot-side heat dissipation mode, water-cooling efficient is higher than the forced air cooling heat radiation; Heat exchange area of dissipation in hot junction is big more, and the coefficient of heat transfer is big more, and when one timing of the hot junction coefficient of heat transfer, there is an optimum value in choosing of operating current.Needs that the operating current set basis is different and use tendency have ε
Max, Q
Max, four kinds of states of E, S can be used as design considerations.Press constant power state design theory, the intersection point E that gets curve Q and W is as the ideal operation state.Under this state, IE=219A, ε=1, QE=170W, the refrigerating capacity of each thermoelectric pile is 55% of a maximum cooling capacity; When getting I=210A, Q=120W then, ε=1165, the refrigerating capacity of each thermoelectric pile is 40% of a maximum cooling capacity, this is a kind of design of tending to obtain big coefficient of refrigerating performance.Experimental result and design imagination basically identical.
