In addition, be in due course down, above-mentioned two kinds of processes can hocket, greatly to accelerate the recovery speed of individual systemRate: in the time that ammonium nitrate dissolves, system is in energy storage state; In the time of ammonium nitrate Precipitation, system is in exoergic state---because ofThis this system can realize in the short time restores and recycles.
When this system works, satisfied condition is: need target temperature that the object of alternating temperature will reach (generally close to ringBorder temperature) between the initial temperature of this object and the initial temperature of native system, (conventionally close to environment temperature, or last process is lostThe temperature staying) between.
Described loop module can adopt pump or other conveying devices.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
1, be far smaller than under the prerequisite of common large thermal source in volume, quality, there is close temperature stability and continue ensureingFast neither endothermic nor exothermic---due to ammonium nitrate high separate out heat and the utmost point of solubility with temperature in certain temperature rangeLarge rate of change makes this system possess extremely strong storage, exoergic ability, in system, also can maintain contact temperature without containing large quantity of materialAfter spending abnormal object, internal temperature remains basicly stable to carry out continuously and healthily heat exchange, and this makes volume and quality very limitedThis system can be similar to and replace sizable low temperature or high temperature heat source to carry out work, simultaneously this also just this system want realExisting object;
2, while work, do not need extraneous input energy, do not need the cooling cycle systems such as cold-producing medium Phase Transition Systems, be greatly better than systemCold machine;
3, can Infinite Cyclic use in theory, disposable irreversible temperature varying system is proved definitely inferior;
4, can heat up rapidly, can lower the temperature rapidly again, there is remarkable superiority than the system of simple refrigeration or heating;
5, can make to be applied object and be tending towards the arbitrary temp (being roughly tending towards in system initial temperature) in very large temperature range;
6, these two kinds of discrete state material cheapnesss of water and ammonium nitrate, and there is certain acidity, ammonium nitrate solid except aqueous ammonium nitrate solutionOutside can decomposing or explode, can think to human body nontoxicity to there is stronger market competition under extremely harsh extreme conditionPower;
7, the operating temperature that this system is suitable is comparatively extensive, and in theory, its operating temperature range is exactly that ammonium nitrate solution canThe temperature range of stable existence, from a little less than 0 DEG C to 100 DEG C left and right;
8, due to the energy storage characteristic of the antagonism alternating temperature of temperature controlled fluid, when this system initial temperature is close to environment temperature, at environmentUnder the situation that temperature is on the low side, process object to be lowered the temperature, or under the higher situation of environment temperature, process in the time heating up object decapacitationFast enough and pending object levels off to outside preference temperature jointly, can also make pending object together with system, in preference temperatureThe near maintenance long period.
