Selection for temperature upper limit F1 and temperature upper limit value F2 is different at a temperature of unit works from varying environment
, by taking common air-cooled ducted air conditioner as an example, when under refrigeration work mode, F0>27 DEG C, outer blower low wind file operation, F0<24 DEG C, exogenous wind
Machine high windscreen operation, so threshold values is respectively F1=27 DEG C, F2=24 DEG C, similarly when heating under operating mode, F1=16 DEG C,
F2=13 DEG C, specific value is determined by blower actual parameter outside difference and unit capacity.
Above-described embodiment in order to better understand carries out detailed explanation below in conjunction with a specific embodiment.
In one embodiment, Fig. 7 is referred to, after getting environment temperature, first determines whether environment temperature is greater than temperature upper limit
F1, if so, it is modified step number control, if it is not, then continue to judge whether environment temperature is less than temperature upper limit value F2, if so,
It is then modified step number control, changes air-conditioning amount if it is not, then carrying out normal step number control and haves no need to change air-conditioning
Amount.Correcting step number control, detailed process is as follows:
By taking area control system as an example, there was only one inner blower of an outer machine in area control system, not the wind of chummery
For amount by air-valve and air duct air-supply past, room number is different, and chummery set temperature is not different, and static pressure size can all influence
Air volume and practical air-out effect.Remember corresponding target air output W, note is ΔΦ by the modified air output of circumstance temperature.
During unit normal control, air quantity W is the target air output calculated according to fixed demand, and Centralized Controller passes through
Air quantity calculates air-cooled ducted air conditioner air outlet aperture, compressor frequency size.And in practical control process, due to the influence of circumstance temperature, in ring
Heating efficiency when refrigeration or lower circumstance temperature when temperature is higher can all be calculated lower than practical, and practical air output can be less than pre-
Estimate air output.At this time need closed-loop feedback mechanism control blower aperture and press frequency.When circumstance temperature be greater than factory threshold values F1, when
When user opens heating, unit efficiency is very high, and air outlet will do it air quantity throttling, slightly reduction air port air output, to reach
The effect for reducing energy consumption, when user, which opens, freezes, unit efficiency is higher, compared with low circumstance temperature, identical air port aperture system
Cold effect can reduce, so needing slightly to improve air port aperture, to improve unit refrigerating capacity, so that improving user uses body
It tests.With should circumstance temperature be less than factory threshold values F2 when, when user open heat when, need to improve air outlet air quantity；Open system
When cold, air output is reduced.
W is target air output, is example with region 1, it is assumed that region one is 45 cubic metres of space (15 square metres of * 3 meters of height
Degree), in the case of refrigeration, the density p of air is 1.293kg/m3, the specific heat capacity C of air is 1.005kJ/kg, so every reduce by 1
DEG C energy Q=C* ρ * V* Δ t=1.005*1.293*45*1kJ=45.225kJ needed, air-cooled ducted air conditioner needs to be supplied to region one
The energy of 45.225kJ can calculate the target air output of inner blower according to the airspeed out of air-cooled ducted air conditioner refrigerating capacity and inner blower.
Machine is always in air-cooled ducted air conditioner, it is desirable to it controls different air output needs and is controlled by valve area, the energy of 45.225kj
A corresponding air-valve target step number.
Remember that current circumstance temperature is F0, θ is correction factor, is determined by unit fan capacity, is set when installing unit.When
When F0>F1, air quantity ΔΦ=(F0-F1) * θ is corrected, as F0<F2, air quantity ΔΦ=(F0-F2) * θ is corrected, by correcting wind
Amount can calculate compensation aperture, be appended in air-valve control, and air-valve controls step number=target step number+addition step number.To reach
According to the purpose of circumstance temperature Correction and Control.Circumstance temperature is too low, needs additional negative step number control, reduces aperture；The excessively high needs of circumstance temperature chase after
Add positive step number to control, increases aperture.False wind tube mechanism cooling capacity is 10P, 10P=25KW=21495kJ, the specified function of air-cooled ducted air conditioner
Rate operation, only opens single air-valve, can supply the energy of 21495kJ per hour, the temperature reduced according to the target in region 1 and region
1 size, you can get it region 1 need the gross energy supplied, are converted to the tool for accounting for ratio you can get it the air-valve 1 of aggregate supply energy
Body opening size, similarly windy valve can also obtain the opening size of each air-valve, and target step number obtains.Different unit capacities
