The specific embodiment
A kind of air-conditioner dropping equipment of the present utility model comprises the temperature sensor that is installed on the outdoor condenser, is built in the water pump drive circuit on the automatically controlled plate in the air conditioner chamber, is fixed on the spraying cooling device on the off-premises station.As Fig. 1, shown in Figure 3, after air-conditioner is opened refrigeration, water storage box 8 is collected condensed water by air conditioner room unit drainpipe 9, the CPU of controller receives from the temperature data that is installed in the temperature sensor 10 on the outdoor condenser 6, when temperature is higher than 49 ℃ of setting, start water pump 7, water pump 7 is extracted into collector pipe 2 with the condensed water of water storage box 8, because water pump 7 provides enough dynamic pressures, condensed water is by the delivery port 51 of the capillary sebific duct 5 that links to each other with collector pipe 2, be sprayed at the windward side of outdoor condenser 6 with the form of spraying, water evaporates siphons away a large amount of heat of condenser surface, strengthen the heat exchange efficiency of condenser, thereby reached the effect that reduces condensing pressure.As shown in Figure 1,, collector pipe 2 is fixed on the fixed support 1 the install an air-conditioner back side of device off-premises station 4 of fixed support 1 with screw with binding band 3.Collector pipe 2 with if in bar capillary sebific duct 5, be installed at the back side of air-conditioner outdoor unit 4, promptly the windward side of outdoor condenser 6 because capillary sebific duct diameter is less, can not influence the air quantity of condenser.As Fig. 2, shown in Figure 3, the tube wall below of collector pipe is provided with many capillary sebific ducts that are communicated with collector pipe, water in water storage box is pumped in the capillary sebific duct tube chamber, the delivery port of a plurality of pin hole shapes is arranged, on the capillary sebific duct under powerful hydraulic pressure, moisture content is vaporific and sprays out from delivery port, the steam of atomizing fully contacts with condenser, and the absorption condensation thermal evaporation is in atmosphere, simultaneously, condenser temperature descends, and impels condensing pressure to reduce.
As shown in Figure 4, temperature sensor 10 is installed in condenser pipe elbow, outdoor condenser 6 middle part, is used to detect condenser middle part temperature.With welding manner copper sleeve 62 is fixed on elbow, outdoor condenser 6 middle part, columniform temperature sensor 10 is inserted copper sleeve 62 with fixing card 61, because the outside varicose of shell fragment portion (as shown in Figure 5) of fixing card 61, the rubber-like effect, can guarantee that temperature sensor 10 closely contacts with sleeve 62, can not come off, survey the temperature at outdoor condenser 6 middle parts more accurately.
As shown in Figure 6, on the basis of the original control circuit of air-conditioner system, increase a water pump drive circuit 20, water pump drive circuit 20 is built on the indoor set control panel, water pump drive circuit 20 is made up of current-limiting resistance, triode, commutation diode, pump switch relay, wherein, the CPU output connects the current-limiting resistance of 10K, and current-limiting resistance connects the base stage of triode, the colelctor electrode of triode connects Zener diode and pump switch relay, the grounded emitter of triode.Chip CPU receives the signal OPT of temperature sensor, judge whether greater than 49 ℃, if greater than, chip is to PUMP_OUT output+5V voltage, make transistor base that the voltage input be arranged, triode ground level and emitter stage are connected and are made colelctor electrode and the emitter stage conducting of triode, pump switch relay K 5 move adhesives.In the water pump drive circuit 20, the current-limiting resistance of 10K plays metering function, the protection triode.The rectification diode has played the rectifying and voltage-stabilizing effect in circuit.
The data of the temperature sensor on per 40 seconds collection primary condensers of the chip CPU of air-conditioner controller, the data of gathering are judged whether greater than 49 ℃ of setting values, when meeting greater than condition, the controller output voltage signal, the energising of feed pump switch relay, switch relay gets electric adhesive, and pump working draws water and sprays to condenser.If judging, the data that CPU gathers are not more than 49 ℃ of setting values, then not feed pump switch relay energising, and the pump switch relay is an off-state, water pump is not worked.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize the purpose of this utility model with essentially identical means, all should belong to protection domain of the present utility model.
