Therefore, the purpose of changing the heating quantity or the heating effect of the air conditioner can be realized without adjusting the wind speed of the fan of the indoor unit, so that the wind speed of the hot wind of the indoor unit can be stably kept in a range suitable for a user. Meanwhile, the frequency of repeated halt of the compressor can be reduced, and the service life of the compressor is prolonged.
The step of "determining the target superheat degree based on the actual outdoor ambient temperature" in step S2 specifically includes: and inquiring the target superheat degree in the preset corresponding relation between the outdoor environment temperature and the target superheat degree by taking the actual outdoor environment temperature as a retrieval item.
In the control method of the fixed-frequency air conditioner in the heating state provided by the embodiment, the target superheat degree is inquired in the preset corresponding relation between the outdoor environment temperature and the target superheat degree by taking the actual outdoor environment temperature as a retrieval item, so that the purpose of determining the target superheat degree based on the actual outdoor environment temperature is achieved, convenience is provided for adjusting the flow of the refrigerant in the fixed-frequency air conditioner based on the target superheat degree, the wind speed of the indoor unit can be stably kept in a range suitable for a user by the control method, and the same outdoor unit can be matched with indoor units of different types for use.
As a preferred embodiment of the control method provided in this embodiment, the correspondence relationship includes a plurality of outdoor environment temperature ranges and one target superheat degree corresponding to each of the plurality of outdoor environment temperature ranges; as shown in fig. 2, the step S2 when the "search for the target degree of superheat in the preset correspondence between the outdoor ambient temperature and the target degree of superheat" includes:
s21, determining the outdoor environment temperature range where the actual outdoor environment temperature is located by comparing the actual outdoor environment temperature with the end value of each outdoor environment temperature range;
s22, a target superheat degree is determined based on the outdoor environment temperature range in which the actual outdoor environment temperature is located.
As a preferred implementation of the above control method provided in this embodiment, the correspondence may be set in the form of a lookup table or a function. For example, it can be expressed in functional form as:
wherein, a, b, c are target superheat degrees corresponding to different outdoor environment temperature ranges, different values can be set for the target superheat degrees according to different air conditioner types and different specifications of the same type of air conditioner, and-5 ℃ and 7 ℃ are end values of the outdoor environment temperature ranges (which are only examples here, and are not unique in practice).
As a preferred implementation of the above control method provided in this embodiment, as shown in fig. 3, the step of "adjusting the flow rate of the refrigerant in the fixed-frequency air conditioner based on the target superheat degree" in step S3 specifically includes:
s31, acquiring the actual exhaust temperature of the compressor;
s32, calculating the actual superheat degree of the fixed-frequency air conditioner based on the actual exhaust temperature;

The regulation of the indoor temperature is realized by controlling the opening degree of the electronic expansion valve, so that the wind speed of the hot wind of the indoor unit can be stably kept in a range suitable for a user without regulating the wind speed of a fan of the indoor unit. Meanwhile, the frequency of repeated halt of the compressor can be reduced, and the service life of the compressor is prolonged.

TABLE 1
The foregoing describes, by way of example, that for different types of indoor units of the ducted air conditioner, the embedded air conditioner, or the cabinet air conditioner, under the condition that the actual outdoor environment temperature is the same or falls within the same outdoor environment temperature range, the flow rate of the refrigerant in the constant-frequency air conditioner can be adjusted by setting different target superheat degrees, so as to achieve adjustment of the indoor temperature. And because different target superheat degrees are set for the same actual outdoor environment temperature of different indoor units or the same outdoor environment temperature range, and the heating capacity of the air conditioner can be changed by adjusting the flow of the refrigerant in the fixed-frequency air conditioner based on the target superheat degrees, the problem that the same outdoor unit and different types of indoor units are difficult to match for use can be solved.
As a preferred implementation of the above control method provided in this embodiment, the control method further includes: determining the type of the fixed-frequency air conditioner "before" determining the target degree of superheat based on the actual outdoor ambient temperature "at step S2; thus, the step of "inquiring the target degree of superheat in the preset correspondence between the outdoor ambient temperature and the target degree of superheat" specifically includes: and inquiring the target superheat degree in the preset corresponding relation between the outdoor environment temperature of the fixed-frequency air conditioner and the target superheat degree.
