The noise of blower is excessive or enough (whether meeting mute state) at this time, while showing that the external fan-out capability of air-conditioning system is
It is no to reach requirement (meeting the needs of customer charge), it is then adjusted accordingly further according to comparison result, so that air-conditioning
System also ensures that fan-out capability is enough under the silent mode.
Preferably, as Min (TExhaust saturation 1、TExhaust saturation 2) < C2, blower reduce by one grade, detected again after maintaining the gear T2 time,
If also meeting this condition to continue to reduce by one grade, according to this logic, until minimizing frequency A3 (Hz).As Min (TExhaust saturation 1、

It can play due heat spreading function to condensing heat exchanger part, while reducing energy unnecessary waste, reduce blower
Noise has the function that mute idle running is adjusted.
As C2≤Min (TExhaust saturation 1、TExhaust saturation 2)≤C1 then makes blower maintain current gear.As C2≤Min (TExhaust saturation 1、
TExhaust saturation 2Show that the delivery temperature of compressor outlet is relatively suitable when)≤C1, the muting function of air-conditioning system can either be reached
(Min(TExhaust saturation 1、TExhaust saturation 2)≤C1), and be also able to satisfy air-conditioning system under silent mode and externally export energy (mainly cooling capacity)
Reach condition (C2≤Min (T of user demandExhaust saturation 1、TExhaust saturation 2)), outdoor unit heat exchanger (finned heat exchanger) condenses heat release
Situation is enough；
As Min (TExhaust saturation 1、TExhaust saturation 2) > C1, blower increase one grade, detected again after maintaining the gear T2 time, if also full
This condition of foot continues to increase one grade, until rising to most high-grade A1 (Hz).As Min (TExhaust saturation 1、TExhaust saturation 2) > C1 when show compressor
The delivery temperature of outlet is relatively high, enters and carries out condensing heat-exchange in outdoor unit heat exchanger (usually finned heat exchanger)

Caloric receptivity it is relatively high so that the refrigerating capacity generated is higher, under the demand for reaching user, if blower is by common normal frequency
Rate can not suitably be radiated if operating, and not have a due heat dissipation effect, thus will it is excessively slow due to revolving speed and can not
Play due heat dissipation effect but also can bring a part noise, therefore need to improve at this time blower revolving speed (or frequency
Rate) make it possible to play due heat spreading function to condensing heat exchanger part, while the noise of blower is reduced, reach mute idle running
The effect of adjusting.
Preferably, when air-conditioning system is in heating state, the first air-breathing saturation temperature T is utilizedAir-breathing saturation 1And/or second inhale
Gas saturation temperature TAir-breathing saturation 2Be compared between C3 and/or C4 (the two saturation temperatures refer to compressor 1 in air-conditioning system,
The respective air-breathing saturation temperature of compressor 2, sampling low pressure is because blower is steamed in evaporating low pressure side, and at this time when heating when heating
Sending out temperature cannot be too low, too low to will lead to cooling deficiency, too high to will lead to unit overload), according to the result of the comparison to blower frequency
Rate carries out gear adjusting.By being compared in two air-breathing saturation temperature values of selective sampling with C3 and/or C4, can judge
The temperature of compressor air suction mouth is high or low, so judge outdoor unit heat exchanger (being evaporator at this time) caloric receptivity it is big
Small, further judgement show that the noise of blower at this time is excessive or enough (whether meeting mute state), while obtaining air-conditioning
Whether system external fan-out capability reaches requirement (meeting the needs of customer charge), then carries out further according to comparison result corresponding
Adjusting so that air-conditioning system also ensures that fan-out capability is enough under the silent mode.
Preferably, as Min (TAir-breathing saturation 1、TAir-breathing saturation 2) < C4 when, blower reduce by one grade, examined again after maintaining the gear T2 time
It surveys, continues to reduce by one grade if also meeting this condition, according to this logic, until minimizing frequency A3 (Hz).As Min (TAir-breathing saturation 1、
TAir-breathing saturation 2) < C4 when illustrate outdoor unit in refrigerant circulation to outdoor drawn less heat, i.e. the amount of evaporation endothermic compares
It is small, therefore need to consume (the motor drive of extra unnecessary energy by the operating of common normal frequency if blower at this time
Blower rotation), and bring the idle running of a part to release noise, therefore need to reduce the revolving speed (or frequency) of blower at this time just
It can play due heat spreading function to evaporating heat exchanger part, while reducing energy unnecessary waste, reduce blower
Noise has the function that mute idle running is adjusted.
As C4≤Min (TAir-breathing saturation 1、TAir-breathing saturation 2When)≤C3, then blower is made to maintain current frequency.As C4≤Min
(TAir-breathing saturation 1、TAir-breathing saturation 2Show that the suction temperature of compressor air suction mouth is relatively suitable when)≤C3, the quiet of air-conditioning system can either be reached
Audio fruit (Min (TAir-breathing saturation 1、TAir-breathing saturation 2)≤C3), and be also able to satisfy air-conditioning system under silent mode and externally export energy (mainly
Heat) reach condition (C4≤Min (T of user demandAir-breathing saturation 1、TAir-breathing saturation 2)), outdoor unit heat exchanger (finned heat exchanger) evaporation
Situation of absorbing heat is enough；
As Min (TAir-breathing saturation 1、TAir-breathing saturation 2) > C3 when, blower increase one grade, detected again after maintaining the gear T2 time, if also
Meet this condition then to continue to increase one grade, according to this logic, until rising to most high-grade A1 (Hz).As Min (TAir-breathing saturation 1、TAir-breathing saturation 2) <
Show that the suction temperature of compressor inlet is relatively high when C3, entering outdoor unit heat exchanger, (present invention is preferably finned change
Hot device) in be evaporated heat absorption caloric receptivity it is relatively high, further result in and eventually enter into indoor set heat exchanger (usually package
Heat exchanger) in condense that exothermic thermal discharge is relatively high, under the demand for reaching user, if blower is by common normal frequency
Rate can not suitably be radiated if operating, and not have a due heat dissipation effect, thus will it is excessively slow due to revolving speed and can not
Play due heat dissipation effect but also can bring a part noise, therefore need to improve at this time blower revolving speed (or frequency
Rate) make it possible to play due heat spreading function to evaporating heat exchanger part, while the noise of blower is reduced, reach mute idle running
The effect of adjusting.
As shown in Figure 3, it is preferable that if in air-conditioning system normal mode, the most high-grade frequency of compressor is B1 (Hz), deep low gear
Frequency is B3 (Hz)；In silent mode, the most high-grade frequency limit of compressor is B2 (Hz), and deep low gear frequency is B3 (Hz), wherein
B3 < B2 < B1 is adjusted the frequency of compressor after triggering silent mode accordingly.In this way can according to the actual situation and
Demand and by the adjusting to compressor frequency to reduce noise as much as possible, as much as possible in the case where meeting noise demand
Improve the ability that air-conditioning system externally exports.
Preferably, when the air-conditioning system is located at the triggering stage, (1) if compressor frequency Q1 meet B2 < Q1≤
Compressor frequency Q1 is then adjusted to as B2 (Hz) by B1；(2) if compressor frequency Q1 meets B3≤Q1≤B2, by compressor frequency
Rate Q1 maintains current frequency constant.Since compressor frequency range is between B3-A2 (under silent mode), between B3-B1
(under normal mode), therefore in order to guarantee that it keeps mute state during the triggering stage mute herein, if compressor frequency
Q1 meets B2 < Q1≤B1, then shows that the frequency of compressor has exceeded the frequency range of silent mode operation, in order to remain former
Some mute states then need for compressor frequency Q1 to be adjusted to for the maximum frequency B2 (Hz) under silent mode, and work as compressor
Frequency Q1 meets B3≤Q1≤B2 and shows to be now in the frequency range of silent mode restriction, then can maintain current frequency not
Become, such adjusting is to guarantee air-conditioning system in the state of being in silent mode as much as possible in the triggering stage.
Here it is consistent in the adjusting of triggering multistage compressor with Fan Regulation, first frequency reducing guarantees that unit avoids blower
Downshift leads to the excessively high protection of high pressure.
Preferably, when air-conditioning system is located at the adjusting stage: setting C5, C6, C7, C8 as constant, wherein C5 < C6, C7
< C8, according to difference in the case where the frequency Q2 of compressor is adjusted accordingly.Tetra- constants of C5-C8 are by a large amount of
Experimental result and obtain so that air-conditioning system can either be under mute shaping modes and can also ensure that air-conditioning output power
Meet customer charge demand, according under different situation (being adjusted including refrigeration, the states etc. such as heating is adjusted) to the frequency of compressor
Rate is adjusted accordingly.
Preferably, when air-conditioning system is in refrigerating state, first exhaust saturation temperature T is utilizedExhaust saturation 1And/or second row
Gas saturation temperature TExhaust saturation 2Be compared between C5 and/or C6 (the two saturation temperatures refer to compressor 1 in air-conditioning system,
The respective exhaust saturation temperature of compressor 2, when refrigeration sampling exhaust saturation temperature be because blower is in condensing high pressure side when refrigeration,
Need to control high pressure, the too high unit of condensation temperature is dangerous, and too low condensation is insufficient, the first and second exhaust protection temperature here
The first, second exhaust saturation temperature that the blower frequency of degree and front is adjusted is same), according to the result of the comparison to compression
Unit frequency is adjusted.By being compared in two exhaust saturation temperature values of selective sampling with C5 and/or C6, can judge
The temperature of exhaust outlet of compressor is high or low, and then judges the size of the thermal discharge of outdoor unit heat exchanger, is further judged
The noise of blower is excessive or enough (whether meeting mute state) at this time out, while obtaining the external fan-out capability of air-conditioning system
Whether reach requirement (meeting the needs of customer charge), then adjusted accordingly further according to comparison result, so as to have leisure
Adjusting system also ensures that fan-out capability is enough under the silent mode.
Preferably, as Max (TExhaust saturation 1、TExhaust saturation 2) > C6, compressor reduce frequency D1 (Hz), maintain the frequency T2 time
It detects again afterwards, continues to reduce frequency if also meeting this condition, according to this logic, until minimizing frequency B3 (Hz), wherein D1 is
Constant；As Max (TExhaust saturation 1、TExhaust saturation 2) > C6 (if maximum value is more than limit value, show that system high pressure is excessively high, it is any one
A system high pressure is excessively high, must just carry out compressor frequency adjusting；It is also during Fan Regulation in this way, any one satisfaction is wanted
Ask, must just be adjusted) when illustrate that the delivery temperature of compressor outlet is relatively high, into condenser (be outdoor unit at this time,
Outdoor unit heat exchanger is preferably finned heat exchanger in the present invention, cooperate above-mentioned blower carry out accelerate heat exchange effect) it is cold
Matchmaker's temperature is higher, then needs to release relatively large number of heat, therefore at this time if pressing common condenser heat rejection principle,
It needs to increase the revolving speed and running frequency of blower, but if being the noise that in this case then will increase blower operating, makes it can not
Original silent mode is maintained, therefore in order to maintain original silent mode, the present invention then takes the frequency for reducing compressor
Operation, so that Max (TExhaust saturation 1、TExhaust saturation 2)≤C6, to reduce noise, is tieed up so that reducing the thermal discharge of outdoor unit heat exchanger
Hold silent mode；
As C5≤Max (TExhaust saturation 1、TExhaust saturation 2)≤C6 then makes compressor maintain current frequency；As C5≤Max
(TExhaust saturation 1、TExhaust saturation 2Show that the delivery temperature of compressor outlet is relatively suitable when)≤C6, the mute of air-conditioning system can either be reached
Effect (Max (TExhaust saturation 1、TExhaust saturation 2)≤C6), and be also able to satisfy air-conditioning system under silent mode externally to export energy (mainly cold
Amount) reach condition (C5≤Max (T of user demandExhaust saturation 1、TExhaust saturation 2)), outdoor unit heat exchanger (finned heat exchanger) condensation is put
Enthusiastic condition is enough；
As Max (TExhaust saturation 1、TExhaust saturation 2) < C5, compressor increase frequency E1 (Hz), examined again after maintaining the gear T2 time
It surveys, continues to increase frequency if also meeting this condition, until rising to highest frequency B1 (Hz), wherein E1 is constant.Work as Max
(TExhaust saturation 1、TExhaust saturation 2) < C5 when show that the delivery temperature of compressor outlet is relatively low, enter outdoor unit heat exchanger (usually
Finned heat exchanger) in carry out condensing heat-exchange thermal discharge it is relatively low, further result in and eventually enter into indoor set heat exchanger
The caloric receptivity that heat absorption is evaporated in (present invention is preferably case tube heat exchanger) is relatively low, so that the refrigerating capacity generated is lower,
The demand of user is not achieved, although lower into the thermal discharge of condenser at this time, to cause that the noise of blower operating will not be increased
And original silent mode is maintained, but the refrigerating capacity of air-conditioning system is often inadequate at this time, therefore then by the frequency of compressor
It improves, the heat exchange amount of outdoor heat exchange machine can be increased in this way, the refrigerating capacity of indoor heat exchanger may further be improved, then can be improved
The refrigerating capacity of air-conditioning system under silent mode solves the problems, such as that ability is inadequate under silent mode, after maintaining the raising
Gear detects again after the T2 time, if also meeting this condition (Max (TExhaust saturation 1、TExhaust saturation 2) < C5) then continue to increase frequency, it patrols according to this
Volume, until highest frequency B1 (Hz) is risen to, so that improving the refrigerating capacity of air-conditioning system as much as possible under the silent mode.
