Technical field
The utility model relates to a kind of air-conditioning unit, especially a kind of air-cooled air conditioner unit, specifically a kind of air-cooled air conditioner unit smart spraying cooling system.
Background technology
Air-cooled air conditioner unit condensation process is to discharge high temperature and high pressure gaseous refrigerant from compressor, enters in condenser, after the mode by forced convertion transfers heat to outside air, condenses into liquid state, flows to throttling arrangement.In condensation process, if outdoor environment temperature is higher, must cause the unit condensation temperature to raise, pressure at expulsion raises.Now the unit refrigerating efficiency descends, and consumed power increases, and is unfavorable for the safe operation of compressor.Based on this, the insider releases a kind of Intelligent spraying cooling system of air conditioner, by air-conditioning condenser is carried out to atomized water spray, enhanced heat exchange, and then reduce the unit pressure at expulsion, improve operating states of the units, improve refrigerating efficiency simultaneously, reduce energy consumption, be conducive to energy-saving and emission-reduction.
At present to the control of this spray cooling system, in the industry mainly with pressure at expulsion as adjustment signal.Be pressure while being elevated to certain value, open spray cooling device, pressure decreased during to certain value, is closed this device.Although this control mode is simple, be difficult to reasonably control the ON/OFF time of sprayer unit in reality, avoid unnecessary water yield waste; And easily cause maloperation, as abnormal in caused for some reason pressure at expulsion, now sprayed obviously improper.
The utility model content
The purpose of this utility model is the problem for existing spray cooling system poor reliability, designs a kind of air-cooled air conditioner unit smart spraying cooling system, effectively to utilize spray amount, improves the unit operation environment, improves efficiency.
The technical solution of the utility model is:
A kind of air-cooled air conditioner unit smart spraying cooling system, it comprises dc source 12 and magnetic valve 5, it is characterized in that: described dc source 12 1 ends are connected with air-conditioning master control borad 1 by relay 7, the other end is connected with magnetic valve 5, atomizing pump 4 by wire 11, described magnetic valve 5 one ends are connected with water source from the beginning by water purifier 6, and the other end is connected with nozzle 3 by atomizing pump 4; At the condenser middle part, temperature sensor 9 is installed, temperature sensor 9 is connected to master control borad 1 by wire, around condenser, the environment temperature sensor 10 for detecting the condenser ambient temperature is installed, environment temperature sensor 10 also is connected to master control borad 1 by wire.
Described atomizing pump 4 carries pressure protective device, while preventing work, because the pump housing stops up, causes atomizing pump to burn.
The quantity of described nozzle 3 depends on the area of condenser, and its spray angle is adjustable.

The beneficial effects of the utility model are:
It is atomized water that the utility model can be guaranteed to be sprayed onto on condenser, can rationally control the On/Off time of atomizing pump simultaneously, effectively utilizes the water yield, improves the unit operation environment, improves the unit efficiency, reduces energy consumption
.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-master control borad, 2-condenser, 3-nozzle, 4-atomizing pump, 5-magnetic valve, 6-water purifier, 7-relay, 8-water pipe, 9-condenser middle part temperature sensor, 10-environment temperature sensor, 11-wire, 12-dc source.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1.
A kind of air-cooled air conditioner unit smart spraying cooling system, it comprises dc source 12 and magnetic valve 5, described dc source 12 1 ends are connected with air-conditioning master control borad 1 by relay 7, the other end is connected with magnetic valve 5, atomizing pump 4 by wire 11, described magnetic valve 5 one ends are connected with water source from the beginning by water purifier 6, and the other end is connected with nozzle 3 by atomizing pump 4.Described atomizing pump 4 preferably adopts the atomizing pump 4(that carries pressure protective device can be directly from market purchasing), while preventing work, because the pump housing stops up, cause atomizing pump to burn.The quantity of nozzle 3 can be according to the area apolegamy of condenser, and its spray angle is preferably adjustable.Equal mounting temperature sensor at condenser middle part and on every side, the temperature sensor 9 that install at described condenser middle part is connected to master control borad 1 by wire 11, described environment temperature sensor 10 is for detecting the condenser ambient temperature, be connected to master control borad 1 by wire 11, but should be noted that this sensor should avoid the contact of same atomized water.
The utility model spray cooling system comprises two parts: a part is water supply part, basic identical with supply equipment now commonly used, be that running water enters water purifier 6 by water pipe 8, water after softening is sprayed to condenser 2 by magnetic valve 5, atomizing pump 4, nozzle 3 by atomized water, thereby realize improving the unit efficiency, strengthen the purpose of reliability; Another part is intelligence control system (all can adopt custom circuit to be realized), the utility model using condenser middle part temperature with environment temperature as regulating and controlling parameter, the reasonable ON/OFF time of finely regulating spray cooling device.Concrete control principle is as follows:
When environment temperature sensor 10 detects condenser ambient temperature >=33 ℃, this temperature signal is reached to master control borad 1, and master control borad 1 will output signal to relay 7, make it to open, thereby connect dc source 12, to magnetic valve 5 and atomizing pump 4 power supplies, atomized water sprays to condenser 1 through nozzle 3, after spray, if condenser ambient temperature≤32 ℃ detected, by master control borad 1, output signal to relay 7, close dc source 12, system stops spray; When environment temperature sensor 10 detects the condenser ambient temperature in 29 ~ 32 ℃ of scopes, if now condenser middle part temperature sensor 9 detects temperature >=37 ℃, condenser middle part, open spray equipment (concrete control is not repeated), after spray, if temperature≤34 ℃, condenser middle part detected, stop spray; When environment temperature sensor 10 detects condenser ambient temperature<29 ℃, do not open spray equipment.
Innovation of the present utility model is to using condenser middle part temperature and environment temperature as the regulation and control parameter simultaneously, and by above-mentioned control mode, can effectively control the reasonable ON/OFF time of spray cooling device, when increasing unit reliability, improving efficiency, effectively utilize injection flow rate.
The utility model does not relate to the part prior art that maybe can adopt same as the prior art to be realized.
