Technical field

The invention relates to an energy-saving device for an air-cooled central air conditioner, in particular to a self-powered energy-saving numerical control energy-saving device which uses an air-cooled central air-conditioning fan to exhaust wind power generation and has a water spray pipe and a water purification device. Background technique

At present, all air-cooled central air conditioners have one characteristic: In summer cooling, when the inlet air temperature of its condenser is higher, the power consumption of the refrigeration unit is larger, and the amount of refrigeration generated is smaller; When the inlet air temperature of its condenser is lower, the power consumption of the refrigeration unit is smaller, and the amount of refrigeration generated is rather increased. In the winter heating, when the inlet air temperature of its condenser is higher, the refrigeration unit increases the power consumption by a small amount, but the heating capacity increases greatly; on the contrary, when the inlet air temperature of its condenser is lower, the refrigeration Although the unit reduced a small amount of power consumption, the heating capacity dropped drastically. Although there are some measures to cool the air conditioning units in the summer, they all need to use external power energy to achieve the goal, and do not really save energy. In addition, the central air conditioning cooling water is too high in summer, can not really start The effect of cooling down. It can be seen that the air-cooled central air-conditioning system, when the external ambient temperature of the unit is changed, its power consumption also changes, which is determined by its performance characteristics. Take the Carrier 30AQA240 air-cooled central air conditioner as an example: In summer, when the average temperature of the fins of the condenser is 40 °C, the cooling capacity is 548 KW, the input power is 218 KW, and the unit COP is about 2.5. When the numerical control energy-saving device is used, the temperature of the condenser fins after cooling is about 25 °C. The cooling capacity is 688KW, the input power is 185KW, the unit COP is about 3.7, and the increase of COP value is estimated to be about 45%. The power saving rate is 32% (full load).

In winter, when the average temperature of the fins of the condenser is 4 °C, the heating capacity is 623 KW, the input power is 190 KW, and the unit COP is about 3.27. When the numerical control energy-saving device is used, the temperature of the condenser fins after heating is about 15 °C. The heating capacity is 832KW, the input power is 224KW, the unit COP is about 3.7, and the increase of COP value is estimated to be about 13%. The power saving rate is 11% (full load).

In addition, although there is already a cooling device for the central air-conditioning condenser, the water used in the entire device is tap water, and the requirements for optimizing the water quality cannot be achieved. After a long time of use, the heat-dissipating fins of the central air-conditioning condenser are contaminated, corroded and scaled. Seriously, the central air-conditioning condenser heat-dissipating fins will be damaged, so that the central air-conditioning condenser can not work normally. In addition, the principle of energy-saving and cooling is to spray water cooling on the outer grid of the central air-conditioning unit, not the heat-dissipating fins of the condenser. The water spray is directly sprayed, the energy saving effect is not significant, and the spray direction of the nozzle is opposite to the air inlet direction of the condenser of the central air conditioning unit. Thus, although the purpose of water spray cooling can be achieved, the water droplets and the air inlet are opposite. However, the contact time is relatively small, and it is impossible to effectively achieve the effect of energy saving and cooling. In addition, there is only one solenoid valve on the inlet pipe to control the water injection pipe. Once the fault occurs, the central air conditioning unit cannot be guaranteed to cool down and save energy. Summary of the invention

FIG. 3 is a schematic structural view of an embodiment of a self-powered energy-saving numerical control energy-saving device installed on an air-cooled central air conditioner. As shown in FIG. 3, the embodiment of the self-powered energy-saving numerical control energy-saving device of the present invention includes a water spray cooling device, a digital control box 9, a jet heating device, a self-generating device, and a water treatment and conveying device. The specific instructions are as follows:

Water spray cooling device: 特别Specially designed special digital controller 35, according to the external temperature and humidity of the condenser, after the automatic calculation of the automatic control program, accurately control the water spray equipment of the energy-saving device to condense The inlet air of the device is sprayed to cool down. The control process is: The digital controller 35 collects the temperature and humidity data of the external environment of the central air conditioner through the temperature sensor 38 and the humidity sensor 39 at intervals, and the automatic control program is based on the external environment temperature and the phase. When the humidity is small, the water spray time is long, the external environment temperature is low, the relative humidity is large, the water spray time is short, the ratio of the difference between the external ambient temperature and the target temperature drop temperature, the integral algorithm and the humidity limit correction value are combined. The comprehensive calculation mode accurately calculates the data of the corresponding water spray time and non-spray time required for the external environment temperature and humidity at a certain moment, and then is accurately controlled by the digital controller 35 through the water supply solenoid valve control line 26. The water supply solenoid valve 17 that opens and closes the water spray water passage emits a current opening signal corresponding to the water spray time and a current OFF signal corresponding to the water spray time to control the opening and closing frequency of the water spray water supply solenoid valve 17, thereby controlling the water spray. Stop, spray water, spray water and not spray water. In order to achieve multi-spray at high temperature and low spray at low temperature; the best water spray effect when multi-spray at low relative humidity and low spray at high relative humidity. When the water supply solenoid valve 17 is closed, the water in the water pump 14 flows through the water return solenoid valve 16 controlled by the return water solenoid valve control line 27 to the heat insulating water tank 13 to achieve the water saving function. The water spray head 20 covers a circle with a radius of 0.3 m, and the distance between each water sprinkler 20 is 0.6 m. When the outside temperature is high, it can be set according to the water spray amount and the continuity of the water spray. The upper and lower rows of water supply pipes 22, the distance between them is 0.6 meters, the number of water spray nozzles 20 on the upper and lower rows of water supply pipes 22 is equal, and the water spray head 20 has a rotating blade built therein, and the diameter of the water drops sprayed is less than 290 um. Under the water pressure of a standard water pressure of 0.2 MPa, the spray head 20 spray angle is greater than 65 degrees. The water spray head 20 sprays in the same direction as the air intake fins 2 of the condenser, and each spray head 20 is installed in series on the water supply pipe 22, since the cover area of the spray head 20 is a radius of about 0.3 meters. Therefore, the distance between each of the water spray heads 20 is 0.6 meters, and the distance between the upper and lower water supply water pipes 22 is 0.6 meters, so that the distributed water spray head 20 can cover the entire area of the heat dissipating fins 2 of the condenser. When the water is cooled, the inlet air temperature on all the air inlet areas of the condenser fins 2 can be reduced; the water supply pipe 22 needs to be evenly distributed, and the air-cooled central air conditioning unit 1 of the four-sided condenser heat dissipating fins 2 The water supply pipe 22 is divided into two rows, and the number of the water spray nozzles 20 on the upper and lower rows of the water supply pipe 22 is equal, so that the water pressure on the entire waterway is hooked to ensure the spray angle and distance of the nozzle. The device is applied in summer. According to the principle of air spray cooling, the magnitude of the cooling temperature is directly related to the contact area between the water and the air and the fins 2 of the condenser, and the length of the bonding time. The contact area is larger, the contact Time The longer, the greater the cooling rate. In order to increase the temperature drop range, it is necessary to solve the technical problem of increasing the contact area of the water and air and the condenser fins 2 and prolonging the contact time. The technical solution adopted by the technical invention is: 特 a special spray nozzle 20 with a built-in rotary blade, the diameter of the water sprayed by the spray nozzle 20 is less than 50 um, and under the standard water pressure, the spray angle of the spray head is greater than 65 degrees, and the spray The water droplets are uniform in size, uniform in distribution, high in density, and large in coverage area, and increase the contact area between the sprayed water droplets and the air and the condenser fins 2. The water spray head 20 is installed in front of the heat dissipating fins 2 of the central air conditioner condenser, and the nozzle direction faces the heat dissipating fins 2 of the condenser, so that the ejected water drops are directed to the inlet of the condenser, and the misty water drops Sprayed on the condenser fins 2 to evaporate heat, achieving energy saving.

For single or multiple air-cooled central air conditioning units 1, each central air conditioning unit 1 is equipped with two solenoid valves 17 on the water pipes of its inlet inlets, respectively controlling the water injection nozzles 20 of the upper and lower drainage channels to ensure the operation. Under normal circumstances, a group of water spray heads 20 can work normally, and will not affect the energy-saving and cooling effect of the central air-conditioning unit 1 due to the failure of the water spray line. The intelligent digital controller control circuit 26 that is turned on and off is equipped with intelligent A set of control switches in the digital control box 9 of the digital controller are connected; a digital control box 9 equipped with an intelligent digital controller is provided with an intelligent digital controller 35 and a plurality of sets of circuit control switches controlled by the same, digital controller 35 has 4 sets of outputs, can control up to 4 central air-conditioning sprinklers at the same time, each central air-conditioning unit start and stop signal line and one of its waterway solenoid valves 17 are connected by intelligent digital controller control line 26.

After the precise calculation of the self-control program, the jet device of the energy-saving device is precisely controlled to elevate the air in the condenser. The control process is: The digital controller 35 collects the temperature and humidity data of the external environment of the central air conditioner through the temperature sensor 38 and the humidity sensor 39 at intervals, and the automatic control program is based on the external environment temperature, the relative humidity is small, and the jet time is Short, when the external ambient temperature is low, the relative humidity is large, the principle of long jet time, the ratio of the difference between the external ambient temperature and the target temperature rise, the integral calculation algorithm and the humidity limit correction value are combined to calculate accurately. The data of the corresponding jet time and non-jet time required for the external environment temperature and humidity at a certain moment, and then the digital controller 35 passes the hot air blower and the blower power supply line 25 to accurately emit the corresponding jet time to the hot air blower 18 and the blower 19. And the control does not correspond to the jet time, thus precisely controlling the jet stop, jet spacing, jets and no jets.

The device is applied in winter. According to the principle of heating the air to the hot air, the magnitude of the temperature rise is directly related to the contact area between the hot air and the heat dissipating fin 2 of the condenser, and the length of the bonding time.
