The air conditioner of the present invention is an integral inverter air conditioner.
The embodiment of the refrigeration control method of the air conditioner comprises the following steps:
the air conditioner refrigeration control method of the embodiment is an application program applied to the air conditioner of the above air conditioner embodiment, and is used for performing refrigeration control on the air conditioner.
Referring to fig. 5, in the present embodiment, when the air conditioner cooling control method is in operation, step S1 is first executed to enter the cooling state at the target frequency of the compressor and the target opening degree of the electronic expansion valve. When the compressor is started for cooling, the target frequency of the compressor operation and the target opening degree of the electronic expansion valve are determined according to the indoor temperature, the outdoor temperature, the set windshield and the set temperature detected during starting, which are well known to those skilled in the art and will not be described herein again.
After the operation is performed at the target frequency of the compressor and the target opening degree of the electronic expansion valve, step S2 is performed to determine whether the cooling operation time period reaches a first preset time period. When the refrigerating operation time reaches the first preset time, the current refrigerating state can be determined to be close to entering the temperature and humidity stability maintaining state. The temperature and humidity maintaining state refers to a state that the temperature and the humidity are controlled to be in target range values. The first preset time period can be preset according to experimental data, and preferably, the first preset time period is 5 minutes.
When the cooling operation length does not reach the first preset length of time, the process continues to step S2. When the cooling operation reaches the first preset time length, step S3 is executed to control the evaporating temperature of the indoor heat exchanger according to the target evaporating temperature interval. The target evaporation temperature interval is determined according to the dew point temperature corresponding to the set relative humidity. Preferably, the relative humidity of 40% to 60% is in a comfortable air humidity range, and the target evaporation temperature is set to be about 1 ℃ to 3 ℃ lower than the dew point temperature. The specific corresponding relationship among the set temperature, the dew point temperature corresponding to the set relative humidity and the target evaporation temperature interval is as follows:
referring to fig. 6, when the step of controlling the evaporation temperature according to the target evaporation temperature section is performed, step S31 is first performed to obtain the current evaporation temperature. The current evaporation temperature may be obtained by the evaporation temperature bulb 14.
After the current evaporation temperature is obtained, step S32 is executed to determine whether the current evaporation temperature reaches the target evaporation temperature range. The target evaporation temperature interval is a condition for judging whether the current working state enters a temperature and humidity stability maintaining state. If the current evaporation temperature reaches the target evaporation temperature interval, it is indicated that the temperature and humidity stable state is satisfied, and at this time, step S4 is executed to enter the temperature and humidity stable state.
If the current evaporation temperature does not reach the target evaporation temperature interval, step S33 is executed to adjust the frequency of the compressor by a preset frequency amplitude and to adjust the opening of the electronic expansion valve by a preset opening amplitude. The preset frequency amplitude and the preset opening amplitude are preset through experimental data. In this embodiment, the step of adjusting the frequency of the compressor by a preset frequency amplitude and the opening of the electronic expansion valve by a preset opening amplitude includes: if the current evaporation temperature is higher than the target evaporation temperature interval, increasing the frequency of the compressor by a preset frequency amplitude and increasing the opening of the electronic expansion valve by a preset opening amplitude; and if the current evaporation temperature is lower than the target evaporation temperature range, reducing the frequency of the compressor by a preset frequency amplitude and reducing the opening of the electronic expansion valve by a preset opening amplitude.
After the compressor frequency and the opening of the electronic expansion valve are adjusted, step S34 is executed to wait for a preset time period. The preset duration can be set according to actual needs. In order to reduce frequent operation, after the compressor frequency and the electronic expansion valve opening degree are adjusted for a preset time period, the steps S31 and S32 are returned to be executed, and the adjusted current evaporation temperature is judged until the current evaporation temperature is in the target evaporation temperature range.
After entering the temperature and humidity stability maintaining state, the temperature and the humidity need to be subjected to stability maintaining control. When the humidity is subjected to the stability maintaining control, referring to fig. 7, when the temperature and humidity stability maintaining state is entered, step S5 is executed to control the opening and closing state of the air port valve according to the evaporation temperature. When the temperature and humidity are in a stable state, the indoor humidity needs to be controlled stably, and whether the air port valve 10 needs to be opened or not is determined through the evaporation temperature.
In this embodiment, referring to fig. 8, when the opening and closing state of the tuyere valve is controlled according to the evaporation temperature, step S51 is executed first to determine whether the evaporation temperature is less than or equal to the opening temperature of the tuyere and lasts for a third preset time. And if the evaporation temperature is less than or equal to the opening temperature of the air opening and lasts for a third preset time, the current indoor relative humidity does not meet the humidity requirement. Therefore, step S52 is executed to control the tuyere valve to open. The air port valve 10 is controlled to be opened, and the indoor fan 11 pumps the wet air in the heating cavity 7 into the room for humidity adjustment. And (5) controlling the opening operation of the air inlet, executing the step S53, and judging whether the evaporation temperature is detected to be greater than the air inlet closing temperature and lasting for a fourth preset time. And when the evaporation temperature is not greater than the tuyere closing temperature for the fourth preset time period, continuing to execute the step S52. When the evaporation temperature is greater than the tuyere closing temperature and continues for the fourth preset time length, it indicates that the current indoor relative humidity meets the humidity requirement, and therefore, step S54 is executed to control the tuyere valve to close.
It should be noted that the tuyere opening temperature, the tuyere closing temperature, the third preset time period and the fourth preset time period may be preset according to experimental data. In this embodiment, the opening temperature of the tuyere is set by taking the dew-point temperature corresponding to 50% relative humidity as a reference at a temperature of 27 ℃, and the closing temperature of the tuyere is set by taking the dew-point temperature corresponding to 60% relative humidity of each ambient temperature, for example, the following table can be referred to:
after entering the temperature and humidity stability maintaining state, when the temperature is controlled to maintain stability, referring to fig. 9, when entering the temperature and humidity stability maintaining state, step S6 is executed to determine whether the indoor temperature is decreased to the preset temperature and continues for a second preset time. And when the indoor temperature is reduced to the preset temperature and lasts for a second preset time, the temperature is too low and needs to be adjusted. The preset temperature and the second preset time can be set as required, preferably, the preset temperature is 1 ℃ lower than the set temperature, and the second preset time is 3 minutes.
If the indoor temperature does not meet the predetermined temperature and continues to drop for the second predetermined time, the step S6 is continuously executed for continuous monitoring. When the indoor temperature decreases to the preset temperature and continues for the second preset duration, step S7 is executed to obtain a decreasing rate of the indoor temperature within the preset time period. In this example, the rate of decrease was calculated from the time taken to detect a decrease of 0.5 ℃ in the room temperature. The descending rate can reflect the current compressor frequency and the opening degree of the electronic expansion valve, and the adjustment range of the compressor frequency and the opening degree of the electronic expansion valve can be determined through the descending rate.
After the descent rate is obtained, step S8 is executed to obtain the corresponding compressor decreasing frequency and electronic expansion valve decreasing opening degree according to the range of the descent rate. The range in which the lowering rate is located may be set in advance in correspondence with the compressor reduction frequency and the electronic expansion valve reduction opening degree, for example, the time taken for the indoor temperature to fall by 0.5 ℃ is expressed as d Δ t/d (0.5 ℃), if 0 ≦ d Δ t/d (0.5 ℃) ≦ 3min, which indicates that the temperature falls fast and the frequency is high, the compressor reduction frequency is 8Hz, if 3min < d Δ t/d (0.5 ℃) ≦ 6min, the compressor reduction frequency is 6Hz, if 6min < d Δ t/d (0.5 ℃) ≦ 10min, the compressor reduction frequency is 4Hz, if 10min < d t/d (0.5 ℃) ≦ 15min, the compressor reduction frequency is 2Hz, if 15min < d t/d (0.5 ℃) ≦ 10min, the frequency is maintained constant, the electronic expansion valve reduction opening degree is adjusted in correspondence with the value of the compressor reduction frequency, and the electronic expansion valve reduction opening degree is equal to the value of a frequency a reduction frequency, a is a preset coefficient.
After the compressor decrease frequency and the electronic expansion valve decrease opening degree are acquired, step S9 is executed to decrease the compressor frequency at the compressor decrease frequency and decrease the electronic expansion valve opening degree at the electronic expansion valve decrease opening degree. The frequency of the compressor is reduced by the frequency of the compressor, and the opening degree of the electronic expansion valve is reduced by the opening degree of the electronic expansion valve.
After the compressor frequency and the opening degree of the electronic expansion valve are adjusted, step S10 is executed to determine whether the evaporation temperature is increased to the upper limit temperature corresponding to the current set temperature. The current set temperature is a target temperature for operating refrigeration, and the set temperature corresponds to an upper limit temperature at which an evaporation temperature is set, for example, as follows:
and if the evaporation temperature is not increased to the upper limit temperature corresponding to the current set temperature, operating at the adjusted compressor frequency and the opening degree of the electronic expansion valve, and continuously detecting the evaporation temperature. If the evaporation temperature is increased to the upper limit temperature corresponding to the current set temperature, step S11 is executed, and the compressor frequency and the opening of the electronic expansion valve are stopped to be adjusted downward. When the evaporation temperature rises to the upper limit temperature corresponding to the current set temperature, the compressor frequency and the opening degree of the electronic expansion valve cannot be adjusted downwards any more, and the operation needs to be stopped.
After the compressor frequency and the opening of the electronic expansion valve stop being adjusted downward, step S12 is executed to determine whether the current indoor temperature is kept within the target range within the target time period. Whether the current indoor temperature is maintained stable can be determined by a variation value of the temperature, which is a well-known technique. If the current indoor temperature is kept stable, step S13 is executed to keep the current state and operate at the current compressor frequency and the opening of the electronic expansion valve. If the current indoor temperature cannot be maintained stable, step S14 is executed to control the windshield to decrease the preset windshield amplitude. Preferably, the windshield amplitude is preset to lower the current windshield by one gear. The current indoor temperature can not remain stable, then explains that the regulation of compressor frequency and electronic expansion valve aperture can't satisfy temperature regulation, needs control windscreen to carry out temperature regulation, consequently, control windscreen reduces and predetermines windscreen amplitude operation.
