Example one
An air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
As shown in fig. 1, the outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor 11 and an outdoor heat exchanger 12, the indoor unit of the air conditioner includes an indoor heat exchanger 13, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger 13 and the outdoor heat exchanger 12 function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
The indoor unit is connected to an outdoor unit installed in an outdoor space through a pipe. The outdoor unit may be provided with a compressor 11, an outdoor heat exchanger 12, an outdoor fan 14, an expander and the like for a refrigeration cycle, the outdoor fan 14 being driven by an outdoor fan, the indoor unit being provided with an indoor heat exchanger 13 and an indoor fan 15, the indoor fan being driven by an indoor fan.
The outdoor fan is coupled to one side of the outdoor fan 14, and the indoor fan is coupled to one side of the indoor fan 15. The outdoor fan is driven to provide a rotational force to the outdoor fan 14, and the indoor fan is driven to provide a rotational force to the indoor fan 15.
The indoor fan 15 is used to suck air in the indoor environment into the indoor unit, exchange heat with the refrigerant in the indoor heat exchanger 13, and then blow out the air by the indoor fan 15. The outdoor fan 14 is for sucking air in the external environment into the outdoor unit, exchanging heat with the refrigerant in the outdoor heat exchanger 12, and then blowing out the air by the outdoor fan 14.
The fan speed is generally set when existing air conditioning products leave a factory. The rotating speed of the indoor fan is generally determined according to the difference between the indoor temperature and the set temperature, and the rotating speed of the outdoor fan is generally determined according to the ambient temperature, so that the temperature of the outdoor heat exchanger is stabilized within a certain temperature range.
Generally, as the rotating speed of the fan is increased, the air quantity is increased, but the consumed power is increased at the same time. For air conditioning heat exchangers, the gains from increased air volume are not linear. When the air quantity is small, the capacity can be rapidly increased by increasing the air quantity, but after the air quantity is increased to a certain degree, the contribution of the increase of the air quantity to the increase of the heat exchange quantity of the heat exchanger is smaller and smaller. Therefore, current fan regulation methods do not allow the air conditioning system to operate at optimal performance.
In order to solve the above problem, this embodiment provides a fan optimization adjusting method, including:
as shown in fig. 2, the outdoor fan optimization adjusting step S0 includes:
detecting indoor temperature Tair;

The refrigeration and heating principle of the air conditioner is the transportation of energy, outdoor cold or heat can be transported to the indoor, and the heat exchange performance of the outdoor heat exchanger plays a key role in the energy efficiency of the air conditioner. According to the method, when the air outlet temperature of the indoor unit meets the set temperature and the energy efficiency of the air conditioner meets the condition, the rotating speed of the outdoor fan is reduced firstly, so that the energy-saving effect is achieved.
When the current energy efficiency is more than or equal to the last energy efficiency, the rotating speed of the outdoor unit fan is reduced. In the embodiment, the reduction amplitude of the rotating speed of the outdoor fan is delta N revolutions per minute preferably. Wherein, δ N is a preset parameter and is stored in the air conditioner.
And after reducing the rotating speed of the outdoor fan and keeping running delta t, returning to the step of optimizing and adjusting the outdoor fan. That is, after the standby group runs for δ t time, the standby group returns to collect relevant data again.
And when the current energy efficiency is more than or equal to the last energy efficiency, reducing the rotating speed of the fan of the indoor unit. The reduction amplitude of the rotating speed of the fan is delta N per time, and the rotating speed is rotated per min; and then, after the standby group runs for delta t time, returning to collect the related data again.
And when the current energy efficiency is lower than the last energy efficiency or the current room temperature cannot meet the requirement, the last fan rotating speed is recovered. And entering the indoor fan rotating speed to adjust, and starting to adjust the indoor fan rotating speed.
Namely, in the step of optimally adjusting the outdoor fan, when the absolute value of Tair-Tset is more than or equal to delta T, the rotating speed of the outdoor fan is increased, and the step of optimally adjusting the indoor fan is entered to adjust the rotating speed of the indoor fan.
Starting an indoor fan entering optimization and adjustment step, and collecting related sensor parameters at first. And judging whether the current room temperature meets the requirement (because the previous step is met, the condition is necessarily met when the indoor fan enters the indoor fan optimization adjusting step for the first time). And calculating the system capacity, power and energy efficiency after meeting the requirements.
In the step of optimally adjusting the outdoor fan, when COP is less than COP', the step of optimally adjusting the indoor fan is carried out, and the rotating speed of the indoor fan is adjusted.
In addition, the heat exchange area of the general outdoor fan is large, and the adjusting range is large, so that the outdoor unit with large adjusting range can be adjusted firstly. On the other hand, the indoor fan faces to the user, so that the outdoor fan is adjusted firstly and then the indoor fan is adjusted, and the influence on the user is reduced.
Before entering the step of optimizing and adjusting the outdoor fan, the method also comprises the step of detecting the running state of the fan, and entering the step of optimizing and adjusting the outdoor fan after the fan runs stably.
The air conditioner start-up process involves control of the compressor and the fan and is not involved here. The fan speed regulation described in this patent is initiated after the air conditioner is operating steadily. First, parameters are initialized.

Such as: compressor suction pressure Ps, compressor discharge pressure Pd, compressor rotation speed N, outdoor unit fan rotation speed N0, indoor unit fan rotation speed N1, indoor temperature Tair, and set temperature Tset. And then judging whether the current indoor temperature meets the requirement, wherein delta T is a temperature error limit, and when the absolute value of the difference value between the indoor temperature and the set temperature is within the temperature error limit, the air conditioner is considered to meet the user requirement (note that the fan rotating speed optimization process is started after the air conditioner operates stably, so that the absolute value of the difference value between the indoor temperature and the set temperature is within the temperature error limit when the air conditioner is started for the first time).

P＝b1+b2*Ps+b3*Pd+b4*N+b5*Ps^2+b6*Pd^2+b7*N^2+b8*Ps*Pd+b9*Ps*N+b1 0*Pd*N+b11*Ps^3+b12*Ps^2*N+b13*Ps*N^2+b14*Pd*N^2+b15*Ps*Pd*N (6)。

It should be noted that, in the process of adjusting the rotation speed of the external machine and the rotation speed of the internal machine, when the indoor temperature does not reach the user set value, the fan control system does not perform any adjustment, and at this time, the air conditioner is adjusted by the self-contained capacity control system of the air conditioner, so that the indoor temperature reaches the user set value, and at this time, the fan control system can enter the control system for adjusting the rotation speed of the outdoor fan and the rotation speed of the indoor fan, so as to obtain the optimal running rotation speed corresponding to COP.
Detecting the fan running state includes: detecting one or more of the running parameters of the unit, namely compressor discharge pressure Pd, compressor suction pressure Ps, compressor rotating speed N, outdoor fan rotating speed N0 and indoor fan rotating speed N1.
