Abstract
This invention is descaling device for air conditioner heat pump assembly water heat exchanger. It includes water heat exchanger, circulating water pump, filling tank with scale dissolver, drain valve, three-way valve and magnet valve. The water inlet pipeline and water outlet pipeline of the said water heat exchanger are connected to three-way valve one and three-way valve two respectively. The bypass of the three-way valve one connects to the bypass of the three-way valve two through magnet valve one, circulating water pump, filling tank and magnet valve two. The pipeline between magnet valve one and circulating water pump is connected with drain valve. This invention can automatically remove the scale in the water heat exchanger under the operation of controlling system. Its descaling efficiency is high.
Description
Technical field
The present invention relates to the central air-conditioning technical field, especially for the apparatus for eliminating sludge of water-to-water heat exchanger in the air conditioner and heat pump unit.
Background technology
After water-to-water heat exchanger work a period of time in the central air-conditioning source pump, incrustation scale can be adhered in the water-to-water heat exchanger surface.If untimely removal incrustation scale, to cause a lot of harm to unit: compare with the thermal conductivity factor of heat exchanger material, therefore the thermal conductivity factor of incrustation scale is much smaller, has increased the heat transfer resistance of heat exchanger, has reduced the heat exchange amount of heat exchanger and has reduced refrigeration, the heating capacity of whole unit; The generation of incrustation scale can cause the deterioration of condensing pressure and evaporating pressure, strengthens consumption of compressor; Incrustation scale can make actual internal area minimizing in the water system, increases water resistance and water pump power consumption; Incrustation scale can corrode heat exchanger, shortens the service life of heat exchanger.Therefore, when having the central air-conditioning source pump operation of water-to-water heat exchanger, should regularly carry out examination of water, and carry out scale removal according to check result and handle.
Conditional electronic (magnetic) antiscale that prior art adopts, the reactivity that descaling method can improve water to a certain extent reach the solubility to incrustation scale, thereby reach the purpose of scale removal, antiscale.Because the characteristic difference of water under the different condition, when especially water temperature was higher, common electronics (magnetic) descaling equipment descale effect was relatively poor, and it is higher really to reach the electronic scale remover equipment manufacturing cost of descale effect, and operating cost is also higher.
In addition, the method that adopts of artificial scale removal has two kinds of mechanical ablution and chemical cleaning methods.The machinery ablution adopts method scale removal such as water spray cleans, the cleaning of spray vapour, sandblast cleaning, scraper scale removal, wire brush scale removal, often heat exchanger must be disintegrated.Chemical cleaning method be in fluid with scale remover, reduce the adhesive force of incrustation scale at the heat exchanger wall, incrustation scale is peeled off from heat exchanger.During cleaning, must outside the air-conditioning unit, former water system be transformed,, connect cleaning equipment etc. as on water lines, welding detergent line.Above-mentioned two kinds of cleaning methods all need manual operations, the operating procedure complexity, and the compressor emergency shutdown time is long, and expense is higher, especially is not suitable for the use of minitype air conditioner source pump scale removal.
Summary of the invention
At above-mentioned deficiency of the prior art, the purpose of this invention is to provide a kind of apparatus for eliminating sludge that is used for air conditioner heat pump set water heat exchanger.It can remove the incrustation scale in the water-to-water heat exchanger automatically under the operation of control system, have compact conformation, scale removal efficient height, the characteristics that operating cost is low.
In order to realize the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of apparatus for eliminating sludge that is used for air conditioner heat pump set water heat exchanger, it comprises water-to-water heat exchanger, water circulating pump, the filling tank of scale remover, drain valve and triple valve and magnetic valve is housed.Its design feature is that the entry pipeline of described water-to-water heat exchanger is connected triple valve one and triple valve two respectively with the outlet pipeline place.The bypass of triple valve one is connected to the bypass of triple valve two successively through magnetic valve one, water circulating pump, filling tank and magnetic valve two.Connect drain valve on the pipeline between magnetic valve one and the water circulating pump.
Compare with prior art, use of the present invention has following advantage:
1, during compressor emergency shutdown, control system operation apparatus of the present invention are removed the incrustation scale in the water-to-water heat exchanger automatically.During scale removal, required quantity of circulating water is few, and reagent consumption is few, scale removal efficient height, and operating cost is low.
2, apparatus of the present invention are built in the central air-conditioning unit, do not increase the installation workload of unit, save construction costs, and it is attractive in appearance not influence the machine room engineering simultaneously.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, the present invention includes water-to-water heat exchanger 1, water circulating pump 4, filling tank 5, drain valve 3 and the triple valve and the magnetic valve of scale remover are housed.The entry pipeline of water-to-water heat exchanger 1 is connected triple valve 1 and triple valve 29 respectively with the outlet pipeline place.The bypass of triple valve 1 is connected to the bypass of triple valve 29 successively through magnetic valve 1, water circulating pump 4, filling tank 5 and magnetic valve 26.Connect drain valve 3 on the pipeline between magnetic valve 1 and the water circulating pump 4.
Before apparatus of the present invention work, stop the operation of central air conditioner system.By the control system operation magnetic valve 1 and magnetic valve 26 are opened, and started water circulating pump 4.Cold water or hot water can circulate in the water-to-water heat exchanger automatic desludging system that water-to-water heat exchanger 1, triple valve 1, magnetic valve 1, water circulating pump 4, filling tank 5, magnetic valve 26, triple valve 29 and water lines 7 are formed under the effect of pressure reduction.Scale remover in the filling tank 5 and water form cleaning fluid, under the dynamic action of water circulating pump 4, water-to-water heat exchanger 1 are cleaned.After cleaning finished, control system was closed water circulating pump 4, magnetic valve 1 and magnetic valve 26, opened drain valve 3 and emitted residual water in the pipeline.At this moment, the incrustation scale that the overwhelming majority washes down rests in the water-to-water heat exchanger 1, when treating that central air conditioner system is moved once more, incrustation scale is dashed from going out unit.Can be lossy after scale remover in the filling tank 5 repeatedly uses, must regular replenishment.
Control system is calculated according to parameters such as time of unit operation, temperature, draws the time of suitable scale removal cycle and each scale removal operation, also can manually set scale removal cycle and scale removal running time by the user.
