Description

Air conditioner constant air capacity control
Technical field
The present invention relates to a kind of control methods of air conditioner, and in particular to a kind of control method of permanent wind amount.
Background technology
With the improvement of living standards, air conditioner use is more and more universal.But use ventilation shaft air-conditioning, with when Between passage and dust the relevant devices such as accumulation aging, the air output of air-conditioning can be less and less, and user will more and more not It is satisfied.Also because of space reasons, long pipe road is needed to blow, long pipe road undoubtedly increases the linear loss of air-supply, Reduce arrival air quantity.Now using permanent Boiler pressure control, the constant wind quantity needed can be maintained under wider static pressure range, from And increase comfort level and have preferable heating or refrigeration effect.
In permanent Boiler pressure control, the technology of most critical is exactly to judge the static pressure of air conditioner wind outlet, so as to rotation speed of fan It makes corrections, reaches permanent Boiler pressure control.Existing method is typically to measure static pressure using static manometer, and cost is higher, and There is the risk of failure in static manometer.Thus, existing method has certain deficiency.
Invention content
The object of the present invention is to provide a kind of cost and risk is relatively low, and the air conditioner permanent wind amount controlling party that precision is higher Method.
In order to achieve the above objectives, the technical solution adopted by the present invention is:
A kind of air conditioner constant air capacity control, for controlling air conditioner, this method includes the following steps:
(1) when being switched on, the constant rotational speed Np for setting the wind turbine of the air conditioner is operated, at this point, with reference to described The torque T of wind turbine judges the static pressure P of the air conditioner;
(2) according to the current desired nominal air quantity Q of the air conditioner of setting, corresponding nominal speed N is calculated;
(3) it is maked corrections with the rotating speed Nb that makes corrections to the nominal speed N, obtains actually required turn of the air conditioner Fast Ns, the correction rotating speed Nb are calculated according to the static pressure P;
(4) obtain the actual air volume Qs of the wind turbine according to the actually required rotating speed Ns, actual air volume Qs with The required nominal air quantity Q is consistent, and the rotating speed for adjusting the wind turbine is actually required rotating speed Ns, so as to fulfill permanent wind amount Control;
(5) when the nominal air quantity Q of the setting of the air conditioner is changed, step (2)-(4) are repeated.
In the above method, when judging the static pressure P of the air conditioner, maked corrections using environment temperature to it.
The method for calculating the static pressure P is:Total pressure efficiencies of the wherein η for the wind turbine, a, B be with the relevant wind turbine characteristic coefficient of environment temperature, γ is constant.
The computational methods that corresponding nominal speed N is calculated according to the nominal air quantity Q are:Q=N*a+b, wherein, a, B be and the relevant wind turbine characteristic coefficient of environment temperature.
The correction air quantity Qb and static pressure P is linear relationship.
The actually required rotating speed Ns is the sum of the nominal speed N and the correction rotating speed Nb.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art:The permanent wind amount of the present invention The method that control method uses mathematical model calculated static pressure, reduces the cost using static manometer, and avoids static manometer failure Risk, have the advantages that precision is high, reaction speed is fast, at low cost, it is applied widely.
Description of the drawings
Control logic figure of the attached drawing 1 for the present invention.
When attached drawing 2 is that static pressure is constant, the air quantity of air conditioner and the relation schematic diagram of rotating speed.
When attached drawing 3 is that air quantity is constant, the static pressure of air conditioner and the relation schematic diagram of rotating speed.
Specific embodiment
The invention will be further described for shown embodiment below in conjunction with the accompanying drawings.
Embodiment one:Referring to shown in attached drawing 1.A kind of air conditioner constant air capacity control for being used to control air conditioner, including Following steps:
(1) calculating of static pressure P:
When air conditioner is switched on every time, some constant rotational speed Np for setting the wind turbine of air conditioner is operated.At this point, with reference to The torque T of wind turbine judges the static pressure P of air conditioner.Static pressure P is about the constant rotational speed Np of setting and the function of torque T.Preferably, In order to increase the reliability of precision and model, in the static pressure P for judging air conditioner, maked corrections using environment temperature to it.Cause This, the method for calculated static pressure P is:Wherein η is the total pressure efficiency of the wind turbine, and a, b are and environment temperature Relevant wind turbine characteristic coefficient is spent, γ is constant.
(2) calculating of the corresponding nominal speed N of nominal air quantity Q:
According to the current desired nominal air quantity Q of the air conditioner of setting, the nominal speed N corresponding to it is calculated.Such as 2 institute of attached drawing Show, in the case where static pressure is constant, the air quantity of air conditioner and the substantially linear relationship of the rotating speed of wind turbine.The calculating of nominal air quantity Q Method is:Q=N*a+b, wherein, a, b be with the relevant wind turbine characteristic coefficient of environment temperature, therefore can be counted according to nominal air quantity Q Calculate corresponding nominal speed N.
(3) calculating of actually required rotating speed Ns:
To make corrections, rotating speed Nb makes corrections to the corresponding nominal speed N of nominal air quantity Q of wind turbine, obtains the reality of air conditioner Required rotating speed Ns.Correction rotating speed Nb is calculated according to static pressure P.As shown in Figure 3, correction air quantity Qb and static pressure P is closed to be linear System.And actually required rotating speed Ns is nominal speed N and the sum of the rotating speed Nb that makes corrections, i.e. Ns=N+Nb.
