Abstract
The invention discloses a control method for adjusting the frequency of an industrial central air-conditioning fan by an energy method, which establishes a minimum supplementary energy-cost function according to the size of energy (heating quantity, refrigerating quantity, humidifying quantity and dehumidifying quantity) supplemented to an adjusted area by an air conditioner, proportionally adjusts the frequency of the fan by adding the proportional relation of the minimum energy and the frequency to correction coefficients of energy supplement forms under different working conditions, finally achieves the effect of smooth control, can ensure the adjustment precision of the temperature and the humidity in an industrial factory building no matter under a static state or a dynamic state, and maximally realizes the energy conservation of the industrial central air-conditioning fan.
Description
Technical field
The invention belongs to technical field of automatic control, relate to the controlling method that a kind of basis is conditioned the size adjustment blower fan frequency of regional makeup energy.
Background technique
Traditional air-conditioning supply air system adopts the pattern of permanent wind amount operation mostly, and blower fan moves under a certain specific power, and energy consumption can't satisfy the requirement of indoor accurate control more greatly and as a rule, has bigger drawback and energy dissipation.Even when adopting frequency conversion fan; General civilian travelling comfort central air-conditioner is the control action of an account temperature, humidity often; Promptly adopt the indoor and outdoor air enthalpy difference as the foundation of regulating the blower fan frequency; Sometimes even only variable of account temperature, with the difference of true temperature and target temperature as the variable of regulating the blower fan frequency.And industrial central air-conditioner should be with the difference of temperature as the variable of regulating the blower fan frequency; Again with the difference of humidity as the variable of regulating the blower fan frequency; Also to consider the requirement of new wind utilization and heating, refrigeration, humidification, the different operating modes of dehumidifying to air quantity; When in realizing, accurately controlling, also to reach purpose of energy saving to industrial premises.
Summary of the invention
The objective of the invention is to deficiency, provide a kind of energy method to regulate the controlling method of industrial central air-conditioner blower fan frequency to existing technology.
The object of the invention is realized through following technological scheme.
A kind of energy method is regulated the controlling method of industrial central air-conditioner blower fan frequency; It is characterized in that: regulate the blower fan frequency to what be conditioned regional institute makeup energy (adding heat, refrigerating capacity, humidification amount, moisture removal) according to air conditioner with being in proportion; Finally reach the effect of level and smooth control, and realize the blower fan energy-saving effect.
The variation of frequency is to determine according to least energy that replenishes under the different operating modes and correction factor; Least energy is to be obtained by the makeup energy-cost function under the different operating modes.
Method of the present invention has the characteristics of high energy saving, high stability for industrial building large spacing factory building constant temperature and humidity system.
Embodiment
Through embodiment the present invention is done to specify further below, but embodiment is not the qualification to technological scheme of the present invention.
Embodiment 1
Technological scheme of the present invention is mainly based on following understanding:
According to air conditioner to the size that is conditioned regional institute makeup energy; Regulate the air quantity size pro rata; That is regulate the blower fan frequency, and the makeup energy branch adds heat, refrigerating capacity, humidification amount, moisture removal, and they may occur two kinds of forms wherein simultaneously; The proportionate relationship of energy and frequency is added the correction factor of different-energy form; The final curve of integrating a nothing jump reaches the effect of level and smooth control, no matter under static state or dynamical state, can both guarantee the degree of regulation of temperature and humidity, and energy-conservation to greatest extent.
The main relation of energy method variable air flow control is following:
f＝k·F(Q，W)
F in the formula---blower fan frequency;
K---energy correction factor;
Q---add heat or refrigerating capacity.When Q is correct time, be for heating, when Q is negative value, be to be refrigeration;
W---humidification amount or moisture removal.When W is correct time, be to be humidification, when W is negative value, be to be dehumidifying;
F---least energy-cost consumption function.
Minimum makeup energy-cost function is following:
F(Q，W)＝min(αQ+βW)
α in the formula---unit adds heat or refrigerating capacity expense;
β---unit humidification amount or moisture removal expense.
According to air conditioner to the size that is conditioned regional institute makeup energy; Set up minimum makeup energy-cost function F (Q; W); The least energy and the proportionate relationship of frequency are added the correction factor of energy supplement form under the different operating modes that satisfy under the indoor temperature and humidity control prerequisite, regulate the blower fan frequency pro rata.
Although above the preferred embodiments of the present invention are described; But the invention is not restricted to above-mentioned embodiment; Those of ordinary skill in the art is under enlightenment of the present invention; Under the prerequisite of aim of the present invention and claim, can make multiple similar expression, such conversion all falls within protection scope of the present invention.
Claims (2)
1. an energy method is regulated the controlling method of industrial central air-conditioner blower fan frequency; It is characterized in that: regulate the blower fan frequency to what be conditioned regional institute makeup energy (adding heat, refrigerating capacity, humidification amount, moisture removal) according to air conditioner with being in proportion; Finally reach the effect of level and smooth control, and realize the blower fan energy-saving effect.
2. controlling method according to claim 1 is characterized in that: the variation of frequency is to determine according to least energy that replenishes under the different operating modes and correction factor; Least energy is to be obtained by the makeup energy-cost function under the different operating modes.
