In an embodiment of the second aspect of the present invention, a control system 400 of an air conditioner is provided, and fig. 4 shows a schematic block diagram of the control system 400 of the air conditioner according to an embodiment of the present invention, as shown in fig. 4, the control system 400 of the air conditioner includes: a first judging unit 10, a second judging unit 12 and a control unit 14.
In the control system 400 of the air conditioner provided by the invention, after the air conditioner is started and the refrigerating time reaches a certain time, the first judging unit 10 judges whether the distance between the outdoor unit and the fixed obstacle is smaller than a preset distance, wherein the preset distance is the normal installation distance of the air conditioner, when the distance between the outdoor unit and the fixed obstacle is smaller than the distance, the air conditioner is judged to be in a narrow installation space, the wind field condition of an outdoor unit condenser is possibly poor, at the moment, the current condensation saturation (cold medium temperature) of the condenser and the current output parameter of the air conditioner are further obtained, the second judging unit 12 judges whether the current condensation saturation and the current output parameter of the air conditioner meet the preset condition, and by judging whether the current condensation saturation meets the preset condition, on one hand, whether the air conditioner is installed in the narrow space is further determined, on the other hand, whether the current output capacity of the air conditioner is primarily judged, whether the current output parameter of the air conditioner meets the preset condition or not is judged to judge whether the current output capacity of the air conditioner is smaller than the required capacity or not, if the current output parameter is smaller than the preset output parameter, the situation that the current capacity of the air conditioner is insufficient due to the fact that the installation space of the air conditioner is narrow is shown, then the control unit 14 controls the air conditioner to operate according to the preset output parameter to improve the output capacity of the air conditioner, so that the capacity attenuation of the air conditioner outdoor unit after being installed in the narrow space of the air conditioner is reduced, and the adaptability of the installation space of the air conditioner is improved.
Fig. 5 shows a schematic block diagram of a control system 500 of an air conditioner according to another embodiment of the present invention.

The second determination unit 22 specifically includes: a third determination unit 222, a second judgment subunit 224, a lookup unit 226 and a third judgment subunit 228.
In this embodiment, a normal installation distance (preset distance), that is, a database of the relationship between the outdoor unit return air temperature increase rate (preset return air temperature increase rate) and the cold medium temperature T (preset condensation saturation) when no narrow space operates is formulated according to the variable working condition table, the corresponding relationship between the outdoor unit return air temperature increase rate and the current capacity requirement (current output parameter) when the installation distance is smaller than the preset distance (narrow space installation) is simulated and saved, the smaller the distance between the air conditioner and a fixed obstacle is, the narrower the installation space is, the poorer the wind field condition of the condenser is, and the faster the return air temperature increase rate is. The output parameter of the air conditioner can be one or combination of the running frequency of a compressor, the running wind speed of a fan and the opening size of a throttling component, the capacity output of the air conditioner can be controlled by regulating and controlling a certain parameter independently, and the capacity output of the air conditioner can also be controlled by the combination of two or three parameters.
When the air conditioner is started, the refrigeration operation starts, the first obtaining unit 26 obtains an initial value of the outdoor unit return air temperature detected by the return air temperature detecting device, after the air conditioner is refrigerated and operated for a period of time, the second obtaining unit 28 obtains the current return air temperature of the outdoor unit at the moment, the first determining unit 30 subtracts the current return air temperature from the initial return air temperature to obtain the return air temperature difference after the air conditioner is refrigerated and the second determining unit 32 compares the current return air temperature with the refrigeration operation time to calculate the return air temperature rising rate, so that whether the air conditioner is in a narrow installation space can be determined according to the return air temperature rising rate of the air conditioner, a distance detecting device does not need to be installed independently, and the cost is saved.
When the air conditioner runs in a refrigerating mode for a preset time, the first judging unit 20 judges whether the distance between the outdoor unit and the fixed barrier is smaller than the preset distance, specifically, the first judging subunit 202 judges whether the current return air temperature rising rate is larger than the preset return air temperature rising rate, if the air conditioner is in a narrow installation space, the air field condition of an outdoor unit condenser is poor, the heat exchange performance of the condenser is obviously attenuated, and the return air temperature rising rate is higher than the return air temperature rising rate in a normal installation space.
After the air conditioner is judged to be in the narrow installation space, the second judging unit 22 judges whether the current condensation saturation of the condenser and the current output parameter of the air conditioner meet the preset condition, and firstly, the third determining unit 222 determines the distance corresponding to the current return air temperature rising rate as the distance between the outdoor unit and the fixed obstacle according to the corresponding relationship between the pre-stored return air temperature rising rate and the distance between the air conditioner and the obstacle; the second judgment subunit 224 judges whether the current condensation saturation is greater than the condensation saturation at the time of the normal installation space; when the current condensation saturation is larger than the preset condensation saturation, on one hand, the installation of the air conditioner in a narrow space is further determined, on the other hand, whether the output capacity of the current air conditioner is smaller than the required capacity is preliminarily determined, then, the searching unit 226 searches for the output parameter corresponding to the distance between the outdoor unit and the fixed obstacle according to the pre-stored corresponding relationship between the distance between the air conditioner and the fixed obstacle and the output parameter, the third judging subunit 228 judges whether the current output parameter is smaller than the preset output parameter, if the current output parameter is smaller than the preset output parameter, which indicates that the output capacity of the air conditioner is insufficient due to the narrow installation space, then, the current condensation saturation and the current output parameter are determined to meet the preset condition, the control unit 24 controls the air conditioner to output and operate according to the required capacity output parameter, so as to reduce the capacity attenuation of the air conditioner after the installation in the narrow space, the adaptability of the installation space of the air conditioner is improved, and the refrigeration effect used by a user is ensured.
