Abstract
The utility model relates to a frequency change adjustor for air quantity, which comprises blowers, an air inlet and an air outlet. The utility model is characterized in that one to two blowers controlled by a three-phase motor, and a frequency changer which can adjust and control the frequency of the three-phase motor are arranged in a machine casing which is provided with the air inlet and the air outlet; an indoor control disk which can control the frequency changer is connected with the frequency changer. The utility model uses the blowers controlled by frequency change to adjust the air sending quantity and to replace the existing end air valves with variable air quantity so as to accurately and automatically control the temperature of adjusted rooms. The utility model is suitable for the end air quantity adjustment in full air low speed air conditioning systems of multiple buildings such as high-grade office buildings, hotels, etc. in air conditioning industry.
Description
The utility model relates to a kind of air bells conditioner.
At the air conditioner system air blast end, generally adopt the different opening of air-valve to regulate air output, this regulative mode air conditioning duct system resistance is big, and power consumption is big, and noise is big.
The purpose of this utility model provides a kind of frequency conversion blast regulator, and under the oepration at full load state, system power consumes little, and noise is low, and can do accurately control to room temperature.
The technical solution of the utility model is:
This frequency conversion blast regulator comprises intake grill and exhaust outlet, it is characterized in that: in the casing that is provided with intake grill and exhaust outlet, 1～2 blower fan by three phase electric machine control is housed, can regulates and control the frequency variator of three phase electric machine frequency, and connect the indoor control panel that to control frequency variator.
Above-mentioned have the non-return lappet at the intake grill place.
Above-mentioned blower fan is two air intake centrifugal formula blower fans or axial fan.
The tenminal block a1 of frequency variator meets three phase electric machine tenminal block b1, the start and stop of control frequency conversion blast regulator;
The tenminal block a2 of frequency variator meets indoor control panel tenminal block b2, sets the start and stop of frequency conversion blast regulator;
The tenminal block a3 of frequency variator meets indoor control panel tenminal block b3, sets cooling;
The tenminal block a4 of frequency variator meets indoor control panel tenminal block b4, sets heat supply;
The tenminal block a5 of frequency variator meets indoor control panel tenminal block b5, the monitoring room temperature;
The tenminal block a6 of frequency variator meets indoor control panel tenminal block b6, sets room temperature.
Working procedure of the present utility model: at the end of full air low speed air-conditioning system, with the utility model be installed in transferred house between in 13 furred ceilings, intake grill is connected with main ajutage, exhaust outlet is according to construction and decoration can give a dinner for a visitor from afar mouth or airduct.Indoorly be provided with indoor control panel 8, indoor control panel is provided with differences such as room temperature setting, cooling setting, heat supply setting, air-conditioning start and stop button is set.After room temperature is set, air-conditioner host 10 and frequency conversion blast regulator 12 are all started working, by the frequency of the temperature difference control three phase electric machine 2 of room temperature measured load and setting value, because three phase electric machine frequency difference makes its air output difference.The summer operation temperature difference is timing, the frequency of rising three phase electric machine, increase air output; Otherwise reduce three phase electric machine frequency, reduce air output.Winter operation and summer operation reversed in order.
The utility model has the advantages that: under the oepration at full load state, system power consumes little, and noise is low, and inrush current operates steadily for a short time, and the life-span is long, and energy-saving effect is obvious.Adopted the blower fan of VFC to regulate air output, substituted existing vav terminal air-valve, a temperature of being transferred house has been done accurately and control automatically.Be applicable to air quantity adjusting terminal in the full air low speed air-conditioning system of many standard width of a room in an old-style house buildings such as air conditioner industry such as high-grade office building, hotel etc.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1; Fig. 3 is the left view of Fig. 1.
Fig. 4 is control principle figure of the present utility model.
As shown in Figure 1, 2, 3, this frequency conversion blast regulator, in the casing 5 that is provided with intake grill 6 and exhaust outlet 7,1～2 blower fan 1 by three phase electric machine 2 controls is housed, can regulates and control the frequency variator 3 of three phase electric machine 2 frequencies, and connect the indoor control panel 8 that to control frequency variator 3.There is non-return lappet 4 at 6 places at intake grill, and blower fan 1 adopts two air intake centrifugal formulas or axial fan.
As shown in Figure 4, frequency variator 3 adopts three phase frequency changing power E2 and two-phase alternating current power supply E1, and the tenminal block a1 of frequency variator 3 meets three phase electric machine 2 tenminal block b1, by the DO1 digital input amount, and the start and stop of control frequency conversion blast regulator;
The tenminal block a2 of frequency variator 3 meets indoor control panel 8 tenminal block b2, sets the start and stop of frequency conversion blast regulator by the DI1 digital input amount;
The tenminal block a3 of frequency variator 3 meets indoor control panel 8 tenminal block b3, is used to set cooling by the DI2 digital input amount;
The tenminal block a4 of frequency variator 3 meets indoor control panel 8 tenminal block b4, is used to set heat supply by the DI3 digital input amount;
The tenminal block a5 of frequency variator 3 meets indoor control panel 8 tenminal block b5, by AI1 analog input amount monitoring room temperature;
The tenminal block a6 of frequency variator 3 meets indoor control panel 8 tenminal block b6, sets room temperature by AI2 analog input amount.
In this air-conditioning system, require air-conditioner host 10 to adopt three phase frequency changing power E4 and three-phase alternating-current supply E3, by 11 controls of 380V frequency variator, main pipe pressure sensor 9 control of being blown of air-conditioning unit 10 air outputs, in control circuit, the tenminal block a7 of 380V frequency variator 11 meets the tenminal block b7 of pressure transducer 9, by AI3 analog input amount monitoring ajutage pressure, compare by pressure signal that monitors and setting value, adjust the output frequency of frequency variator.The tenminal block a8 of 380V frequency variator 11 meets air-conditioning unit 380V three phase electric machine contactor tenminal block b8, by the start and stop of DO2 digital input amount control air-conditioning unit.Generally setting the interior static pressure of ajutage pipe is 20-50Pa (Control Radius according to air-conditioner host 10 is determined by design), when the difference of managing internal pressure measured load and setting value is that timing reduces air-conditioning unit 10 electric machine frequencies, reduces air output; Otherwise rising electric machine frequency, increase air output promptly guarantee to keep in the ajutage micro positive pressure.
