Abstract
The invention discloses a heat transfer medium special for a solar heat pump and a preparation method thereof, which belong to renewable energy source utilization technology. The heat transfer medium is prepared by mixing, heating and stirring ethylene glycol, ionized water, triethanolamine, sodium dihydrogen phosphate, sodium benzoate, phosphoric acid, tolyltriazole styrene, borax, a defoaming agent, an inhibitor and a color concentrate in different weight ratios. The transfer medium has the characteristics of low freezing point, freeze prevention, high low-temperature flowing property, high boiling point, low evaporation loss, high specific heat, high heat conductivity, less foam, high anti-foam performance, and good anti-rust protection and descaling functions for metal pipelines.
Description
Technical field
The invention belongs to field of renewable energy resource utilization, relate generally to a kind of heat transfer medium special for solar heat pump and preparation method thereof.
Background technology
Solar heat pump be in recent years national development " low-carbon economy ", advocate " energy-saving and emission-reduction " and a new technology promoting.But because the time that the solar heat pump technology comes into the market to use is not long, people also do not understand its technical feature, value unit research, not slightly heat-transfer medium research and development.Current, the northern area of China, the heat-transfer medium of solar heat pump is many to be replaced with water.As everyone knows, contain a large amount of alkaline matters in the cold water, after heat collector heating and heat pump compression heat up, will produce incrustation scale, attached to the metallic surface in the unit, can have a strong impact on heat, heat sinking function, the time one is long, causes the unit damage; Northern area, for antifreeze, the heat-transfer medium of solar heat pump many with automobile antifreeze solution for it.In the past few years, we see that in the practical application in Heilungkiang drawback is a lot; One, present domestic market deicing fluid poor quality, fine deicing fluid is generally full organic materials and makes, and does not contain inorganic salt; Produce the tap water that the water of deicing fluid neither be common, but purified ionized water.More domestic producers for pursuing commercial profit, add calcium chloride, salt or alcohol in the entry, and to reach antifreeze purpose, these products of inferior quality do not have antifreeze, antirust, antiscaling effect.Its two, the deicing fluid production formula of different brands is difference to some extent, freezing point also has nothing in common with each other, and should not use with.Use the deicing fluid of different brands with, chemical reaction produces foam mutually, seriously stops up unit.Above problem not only directly influences the integrated heat efficiency of solar heat pump, more can reduce the work-ing life of solar heat pumping set greatly, and solar heat pump technology popularization is produced serious negative impact.For this reason, in the solar heat pump technical system, the heat-transfer medium of being badly in need of a kind of special use of research and development is supporting with it, forms a complete technical system.
Summary of the invention
Purpose of the present invention is exactly the problem that exists at present China solar heat pump technology, design provides a kind of heat transfer medium special for solar heat pump and preparation method thereof, reaches that antifreeze, antirust, anti-foam, nonpoisonous and tasteless, free from environmental pollution, stable performance, heat-transfer effect are good, the purpose of low price, prolongation duration of service.
The object of the present invention is achieved like this: a kind of heat transfer medium special for solar heat pump, this medium is made up of by weight preparation following industrial chemicals: ethylene glycol 38%, ionized water 58%, trolamine 2%, SODIUM PHOSPHATE, MONOBASIC 0.6%, Sodium Benzoate 0.5%, phosphoric acid 0.3%, phenylpropyl alcohol triazole 0.3%, borax 0.25%, defoamer 0.02%, inhibiter 0.02%, look essence 0.01%.A kind of as above-mentioned heat transfer medium special for solar heat pump preparation method, during the medium preparation, whole ethylene glycol mix with ionized water in will filling a prescription earlier, then mixed solution is heated, stir, when mixed solution is warmed to 60-70 ℃, add all the other whole 9 kinds of raw materials in the prescription simultaneously again, continue stirring and promptly got this medium in 4-6 hour.
The present invention is the heat-transfer medium that is exclusively used in solar heat pump, also can be used for all kinds of light load engine-cooling systems of homemade and import, and its characteristics and innovative point are: 1., freezing point is low, and anti-freeze, freezing point-50 ℃, low temperature flowability excellence.2., the boiling point height, 110 ℃ of boiling points, vaporization losses is few.3., the specific heat height, heat conductivity is good.4., the metallic conduit in solar energy collector, the heat pump set scatterer had good corrosion protection and scale removal effect.5., Heat stability is good, can guarantee all have favorable cooling effect under the high and low temperature situation.6., unique pH value modulator effect, make pH value be stabilized in certain level.7., excellent chemical stability, guarantee long-acting antifreeze, the anti-performance of boiling, the four seasons are general.8., foaming is few, anti-bubble performance is good.9., cheap, long service life.
