Description
Technical field
The present invention relates to air conditioning system, the off-premises station being specifically related to air conditioning system cleans device.
Background technology
Air conditioning system includes compressor, condenser, vaporizer, throttle expansion valve etc., compressor sucks the working substance steam from vaporizer lower pressure out, it is allowed to send into condenser after pressure raises, it is condensed into the liquid that pressure is higher within the condenser, after throttle expansion valve throttles, after becoming the liquid that pressure is relatively low, send into vaporizer, in vaporizer, heat absorption is evaporated and is become the steam that pressure is relatively low, thus completes kind of refrigeration cycle.
Wherein, the effect of condenser is the high-temperature high-pressure refrigerant steam that compressor is discharged, and is condensed into liquid refrigerant by heat radiation, and Air-cooled Condenser is a kind of form of condenser, it is using air as cooling medium, takes away a kind of mode of condenser heat by the temperature rise of air.The air conditioning unit outdoor condenser of VRV and air cooling module unit outdoor condenser are all Air-cooled Condenser.
When the surface cooler of processed air Yu air-treatment unit carries out heat exchange cooling and dehumidifying air, because the wall surface temperature of surface cooler is less than the dew point temperature of processed air, processed steam contained by air separates out at surface cooler wall and condenses, when dewdrop increases to the condensation water pond that to a certain degree can be slipped to below surface cooler, thus define condensed water.
The condensed water of present stage does not the most make full use of, and drains in rain sewerage.Certain pollution is all had due to outdoor air, air conditioning system Air-cooled Condenser is after long-play, condenser surface gathers more dust, titbit, winged insect etc. more, has a strong impact on the heat exchange of condenser, causes the increase of air conditioning system power consumption and the reduction of refrigeration.Because polluting difference, generally causing air conditioning system power consumption increases by 5～10%.
Summary of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, it is provided that one can reduce power consumption, make full use of the automatic cleaning system of the air conditioning system air-cooled type off-premises station of condensed water.
The technical scheme is that and be achieved in that:
A kind of automatic cleaning system of air conditioning system air-cooled type off-premises station, including condensed water storage tank, condensed water storage tank is provided with inlet opening, apopore, manhole and spilled water hole, and condensation storage tank top is provided with drainage screen, is provided with water pump bottom condensed water storage tank, water pump is connected with rinsing mother's pipe, rinsing female pipe to be connected with flushing son pipe, rinse sub-pipe and be connected with spray row of tubes, spray row of tubes is provided with nozzle, being provided with liquidometer in condensed water storage tank, liquidometer is connected with water pump.
Condensed water storage tank sidewall is provided with dismountable Access panel.
Condensed water storage tank sidewall is provided with removable cover.
The present invention takes full advantage of air conditioning system condensed water, cleans condenser, while reducing outside air temperature, improves the coefficient of performance of air conditioning system, synthesis energy saving rate 4.2%～8.5%.Condensed water storage tank uses rustless steel modular splicing water tank, it is simple to batch production, is beneficial to promote, makes full use of the condensed water being often wasted.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not paying creative work premise, broadly fall into the scope of protection of the invention.
As shown in figures 1-4, a kind of automatic cleaning system of air conditioning system air-cooled type off-premises station, including condensed water storage tank 1, condensed water storage tank 1 is provided with inlet opening 9, apopore 10, manhole 11 and spilled water hole 19, condensation storage tank 1 top is provided with drainage screen 2, water pump 3 it is provided with bottom condensed water storage tank 1, water pump 3 is connected with rinsing female pipe 5, rinse female pipe 5 to be connected with rinsing sub-pipe 6, rinse sub-pipe 6 to be connected with spray row of tubes 7, spray row of tubes 7 is provided with nozzle 8, is provided with liquidometer 4 in condensed water storage tank 1, and liquidometer 4 is connected with water pump 3.
Operation principle of the present invention is as follows: in an organized way collected to condensed water storage tank 1 by the condensed water of summer air-conditioning system, condensed water storage tank is positioned at the position on the lower, inside of condenser, and condensed water filters through the drainage screen 2 of the attached steel wire of rustless steel microwell plate when importing condensed water storage tank 1.The condensed water in water tank drawn by the miniature water pump 3 arranged below condensed water storage tank 1, through flushing female pipe 5, rinse sub-pipe 6, spray row of tubes 7, nozzle 8 are sprayed at the top of condenser, condensed water is sprayed at above condenser and can clean condenser, condenser thermal transfer coefficient is kept to be basically unchanged, the heat exchange making condenser is unattenuated, and fractional energy savings is 4～8%.General about 16～18 DEG C of condensate temperature simultaneously, evaporation cooling reduces condenser hull-skin temperature, and outside air temperature about reduces by 6～7 DEG C, and all the period of time fractional energy savings is 0.2～0.6%.
The application is through the common effect of two aspects, and fractional energy savings is 4.2～8.5%, and liquidometer 4 controls the start and stop of micro pump.When the water level of condensed water storage tank reaches to set high water level, start water pump 3, when the water level of condensed water storage tank reaches to set low level, stop micro pump and run.
Condensed water storage tank 1 sidewall is provided with dismountable Access panel 12.Condensed water storage tank 1 sidewall is provided with removable cover 13.By Access panel 12 and removable cover 13, in that context it may be convenient to check condensed water storage tank 1 internal state, removal of contamination.
In the application, condensed water storage tank uses rustless steel modular splicing water tank.Rinsing mother's pipe and rinse sub-pipe employing Hylife compo pipe, this tubing is corrosion-resistant, and service life is long；Using and be mechanically connected, installation effectiveness is high, it is not necessary to fire weldering, workman is the most independently operable through short-term cultivation.Nozzle uses rustless steel fine spray nozzle, and water pump uses rustless steel self sucking high-pressure micro pump.
Because polluting difference, general uncleanly condenser can cause air conditioning system power consumption to increase by 5～10%, and after over cleaning, cleaning efficiency is by 80% calculating, saving rate 4～8%.
Now as a example by certain is built, the cooling energy-saving of purging system is calculated, outdoor design dry bulb temperature for summer air conlitioning Twg=34.9 DEG C, summer calculates wet bulb temperature T outside air conditioning chamberws=27.4 DEG C, separately below according to the air cooling module unit of 65kW (module) and the VRV of 28kW (10HP unit) air conditioning unit as a example by, be respectively calculated as follows.
