Second embodiment
The maximum running frequency of convertible frequency air-conditioner is generally determined that certain environment temperature corresponds to certain highest fortune by external environment
Line frequency, synchronization can determine whether to run by highest frequency by way of monitoring external disk temperature, prevent system running pressure
It is exceeded.
Such as outer ring is when being T outer ring, maximum running frequency f, but external disk temperature T external disk reaches certain value A (frequency reducing temperature
Degree, similarly hereinafter) when program can set system by not super f some frequency values operation, to ensure system operational safety.
Requirement with user to air conditioning performance is higher and higher, and the refrigerating capacity under 43 DEG C or more worst hot cases becomes air-conditioning
The core competitiveness of product, the high-temperature refrigeration ability for promoting air-conditioning is the direction of air conditioner industry effort.Legacy frequencies control logic
Face following bottleneck: under outdoor high temperature operating condition, (≤27 DEG C) not frequency reducing was protected when both having required air-conditioner set environment temperature is low indoors
Hold higher refrigerating capacity requires (27 DEG C of >) frequency reducing when environment temperature is high indoors that operating pressure is made to be maintained at zone of reasonableness again
It is interior, in fact, this obviously cannot be satisfactory to both parties under legacy frequencies control logic.
Such as require air-conditioner set energy power rate in 75% or more (27 DEG C of room temperature) under 48 DEG C of outdoor operating conditions, then it requires
Air-conditioner set running frequency at a temperature of 48 DEG C of external environments maintains higher level, at this time because condenser side heat exchange efficiency is low, outside
Disk temperature can be in higher level, and air conditioner can enter in advance frequency reducing to influence the refrigerating capacity of air conditioner.But when interior
Environment temperature is more than 27 DEG C, and when even reaching 32 DEG C or more, system operating load further deteriorates, and condenser pressure is in
Higher level, but external disk temperature compare 27 DEG C when be not obviously improved, frequency reducing condition is not achieved, system operation reliability can not be true
It protects.
A kind of air-conditioning method for controlling frequency conversion is present embodiments provided, for solving existing air conditioner 1 under worst hot case

Include step S10~S30.
S10: outdoor environment temperature and indoor environment temperature are obtained.
Outdoor machine of air-conditioner and indoor unit are provided with temperature sensor, obtain outdoor environment temperature and indoor environment for detecting
Temperature.The maximum running frequency of convertible frequency air-conditioner is generally determined that certain outdoor environment temperature is corresponding certain by outdoor environment temperature
Maximum running frequency, synchronization can determine whether to run by highest frequency by way of monitoring external disk temperature, anti-locking system
Operating pressure is exceeded.In this present embodiment, the outdoor environment temperature and indoor environment temperature are obtained every preset time interval
Degree is every preset time interval, and the temperature sensor detection obtains outdoor environment temperature and indoor environment temperature.Institute
Stating time interval can be 10 seconds, 15 seconds or 20 seconds, and the present embodiment is not construed as limiting this.
S20: external disk frequency reducing temperature is adjusted according to the outdoor environment temperature and the indoor environment temperature.
It is to be appreciated that the corresponding maximum running frequency of air conditioner 1 is different, but existing in different temperature environments
In technology, in the case of a high temperature, outdoor environment temperature limits the frequency of air-conditioning, and when indoor environment temperature is higher, system fortune
Row load can further deteriorate, and frequency reducing condition is not achieved, and system operation reliability is unable to ensure.In this present embodiment, pass through by
The outdoor environment temperature and indoor environment temperature of acquisition are compared with preset temperature value, so as to adjust the external disk of air conditioner 1
Frequency reducing temperature enables air conditioner 1 to take into account refrigerating capacity and reliability.
First temperature threshold and second temperature threshold value are set, wherein the first temperature threshold is outdoor environment high temperature threshold value, the
One temperature threshold is higher than 40 DEG C, for example, first temperature threshold is 48 DEG C.Second temperature threshold value is indoor environment high temperature threshold
Value, second temperature threshold value are higher than 24 DEG C, such as the second temperature threshold value can be 27 DEG C.
When the outdoor environment temperature is higher than the first preset temperature value, the external disk frequency reducing temperature is reduced so that air conditioner
1 enters frequency redution mode in advance.When the outdoor environment temperature is lower than the first preset temperature value, according to the indoor environment temperature
Adjust the external disk frequency reducing temperature.For example, when the outdoor environment temperature is lower than the first preset temperature value and the indoor environment
When temperature is lower than the second preset temperature value, the external disk frequency reducing temperature is adjusted to highest external disk temperature limits value.

S202: whether confirmation indoor environment temperature is lower than the second preset temperature value.
When the outdoor environment temperature of air conditioner 1 is not up to the first preset temperature value, i.e. air conditioner 1 is not at worst hot case
In, generally, air conditioner 1 is run without frequency reducing.But very imaginary root is judged according to indoor environment temperature at this time, if indoor environment temperature
Degree is more than the second preset temperature value, and when even reaching 32 DEG C or more, system operating load is further increased, at condenser pressure
In higher level, but external disk temperature is not obviously improved compared to when understanding the case where indoor environment temperature is 27 DEG C, and frequency reducing is not achieved
Condition, system operation reliability are unable to ensure.So it is pre- in this present embodiment, to judge whether indoor environment temperature is lower than second
If temperature value, second preset temperature value is the indoor environment high temperature threshold value of air conditioner 1, if indoor environment is more than second default
The load of temperature value, air conditioner 1 is excessive, needs to carry out frequency reducing in advance, executes step S204, if indoor environment is not up to second in advance
If temperature value, meeting for air conditioner 1 is at a normal level, and without frequency reducing is carried out in advance, executes step S203.
S023: when the outdoor environment temperature is lower than the first preset temperature value and the indoor environment temperature is pre- lower than second
If when temperature value, the external disk frequency reducing temperature is adjusted to highest external disk temperature limits value.
When outdoor environment temperature is lower than the first preset temperature value, and indoor environment temperature is lower than the second preset temperature value,
Firstly, air conditioner 1 is not in worst hot case, and indoor environment temperature is lower, and meeting for air conditioner 1 is smaller, without being dropped
Frequency is run.At this point, external disk frequency reducing temperature is adjusted to highest external disk temperature limits value, the highest external disk temperature limits value refers to
The saturation temperature of the highest operating pressure allowed by the whole system of air conditioner 1 (need to consider that external disk position compensates and corrects, example
Such as by highest external disk temperature limits value raise 1~2 DEG C), it is ensured that air conditioner 1 under current working will not frequency reducing, guarantee air conditioner 1
Refrigerating capacity.
Step S204: external disk frequency reducing temperature is adjusted to reduction third on the basis of highest external disk temperature limits value and is preset
Temperature value.
It, i.e., will be described outer when air conditioner 1 is under worst hot case when outdoor environment temperature is higher than the first preset temperature value
Disk frequency reducing temperature is adjusted to reduce third preset temperature value on the basis of highest external disk temperature limits value, to ensure air conditioner 1
Frequency reducing can be entered in advance under current working, it is ensured that the reliability of air conditioner 1.
When outdoor environment temperature is lower than the first preset temperature value, and indoor environment temperature is higher than the second preset temperature value,
I.e. air conditioner 1 is not in worst hot case, but room temperature is higher, when 1 load of air conditioner is larger, by the external disk frequency reducing temperature tune
Whole is that third preset temperature value is reduced on the basis of highest external disk temperature limits value, it is ensured that the energy under current working of air conditioner 1
It is enough to enter frequency reducing in advance, to ensure the reliability of air conditioner 1.
In this present embodiment, the third preset temperature value can be 2~3 DEG C, thus ensureing 1 refrigerating capacity of air conditioner
While, ensure the reliability of air conditioner 1.
S30: air conditioner 1 is controlled when 1 external disk temperature of air conditioner reaches the external disk frequency reducing temperature and carries out frequency reducing operation.
