As shown in Figure 3, select the dust stratification grade of different field of employment (presetting dust stratification grade) by the first dial-up 301 (the first dial-up module) on air-conditioner master control borad, the second dial-up 302 (the second dial-up module) sets unit (air-conditioner) Cumulative Elapsed Time in each place.Air-conditioner unit workplace is (as office building, workshop, hotel etc.) different, in air-conditioner unit running process, the speed of dust stratification and thickness have difference to a certain degree, can be by dust stratification grade classification: serious dust stratification, severe dust stratification, moderate dust stratification, several grade such as slight dust stratification, can by the Macintosh of the first dial-up 301, as Macintosh 3011, Macintosh 3012, Macintosh 3013, preset in advance completes, Cumulative Elapsed Time corresponding to each dust stratification grade also has difference, again by the Macintosh of the second dial-up 302, as Macintosh 3021, Macintosh 3022, Macintosh 3023, preset in advance completes, namely by the first dial-up 301 and the second dial-up 302, dust stratification grade under different workplace conditions and Cumulative Elapsed Time are set, when control module 303 detects that air-conditioner unit Cumulative Elapsed Time reaches setting value (presetting the default accumulated running time of dust stratification grade), control module 303 sends automatic purge signal to flushing water pump 304, flushing water pump 304 is opened, condensed water in water receiver 305 is transported to room inside/outside machine water jet 306 and 307, this condensed water is delivered to when condensate pump 310 is opened in water receiver 305 by room inside/outside machine condensate collector 308 and 309, be directly injected on room inside/outside machine heat exchanger 311 and 312 by room inside/outside machine water jet 306 and 307, automatically clean.When automatic scavenging period (presetting scavenging period) reaches, automatic cleaning command terminates, and flushing water pump 304 shuts down, and completes automatic cleaning, and, when the condensed water in water receiver 305 is not enough, moisturizing can be carried out by opening small pump 313, and when too much, by opening water discharge valve 314 draining, wherein, by being arranged on the water level switch 315 sensed water level height on water receiver 305, in condensation water collection process, when detecting that the water level H1 in water receiver 305 is more than or equal to designated water level S1 (the first preset water level height), i.e. H1 >=S1, condensate pump 310 is out of service, or condensate pump 310 continues to run, and draining valve 314 is opened, when water receiver 305 middle water level H1 is less than designated water level S1, i.e. H1<S1, condensed water can be collected always, and when control module 303 detects that heat exchanger needs automatically to clean, first the water level in water receiver 305 is judged, when water receiver 305 middle water level H2 (the second height of water level) is less than designated water level S2 (the second preset water level height), i.e. H2<S2, small pump 313 is opened.When water receiver 305 middle water level H2 is more than or equal to designated water level S2, i.e. H2 >=S2, small pump 313 is out of service; And the temperature information that control module 303 moment monitoring outdoor environment temperature sensor 317 (outdoor environment sensor) feeds back, when outdoor environment temperature is less than 0 DEG C (preset temperature), send order, opening water discharge valve 314, water in water receiver 305 is all emptying, to prevent at low ambient temperatures, by water receiver 305 bursting by freezing, and, only when control module 303 receives the order needing to carry out heat exchanger cleaning, just small pump 313 is opened, make the water level in water receiver 305 reach setting value, then enter and automatically clean operation.Each critical component is all concentrated and is positioned in off-premises station.
Only have outdoor unit heat exchanger 312 to need cleaning when detecting, and when indoor set heat exchanger 311 does not need to clean, then the second magnetic valve 318 is opened, and the first magnetic valve 317 cuts out; Only have indoor set heat exchanger 311 to need cleaning when detecting, and when outdoor unit heat exchanger 312 does not need to clean, then the second magnetic valve 318 cut out, and the first magnetic valve 317 is opened; When detecting that outdoor unit heat exchanger 312 and indoor set heat exchanger 311 all need cleaning, the second magnetic valve 318 is opened, and the first magnetic valve 317 is opened; First magnetic valve 317 and the second magnetic valve 318, in the no clean time, are all in closed condition.
Simultaneously, air-conditioner outdoor unit is under summer high temperature environment during refrigerating operaton, often delivery temperature and pressure at expulsion are all relatively high, condensation effect is poor, the automatically controlled mainboard of off-premises station is by data such as the environment temperature, delivery temperature and the pressures at expulsion that collect, send control module 303 to, control module 303 is according to certain control logic, open flushing water pump 304, water is directly sprayed outdoor unit heat exchanger 312, can effectively reduce delivery temperature and pressure at expulsion, increase condensation effect, improve the overall performance of unit.
More than be described with reference to the accompanying drawings the technical solution of the utility model, heat exchanger can have been realized and automatically clean, and then improve air-conditioner reliability of operation.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
