Detailed description of the invention
The present invention is directed to the problem that existing air-conditioner easily produces condensation, it is proposed that the condensation prevention control method of a kind of new air-conditioner.
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
As it is shown in figure 1, the present embodiment proposes the condensation prevention control method of a kind of air-conditioner, comprise the steps:
S1, detection outdoor environment temperature Tao.
S2, judge that outdoor temperature residing for outdoor environment temperature is interval.
S3, obtain residing for compressor operating upper frequency limit value corresponding to outdoor temperature interval.Wherein, carry out, under various operating modes, the compressor operating frequency values that will produce condensation that test obtains when compressor operating upper frequency limit value is that air-conditioner is in corresponding outdoor temperature interval in advance.And compressor operating upper frequency limit value corresponding for different chamber's external environment temperature range is stored to air-conditioner.
S4, detection indoor environment temperature Tin, and obtain design temperature Ts, according to indoor environment temperature Tin and design temperature Ts, compressor operating frequency is controlled, makes indoor environment temperature Tin reach design temperature Ts.It is preferably PID to control, when compressor operating frequency is carried out PID control, controls the compressor operating upper frequency limit value that the running frequency of compressor is corresponding less than residing outdoor temperature interval.
Preferably, when outdoor environment temperature is in minimum outdoor temperature interval, controls compressor and run according to minimum running frequency.
Outdoor environment temperature is detected by the present embodiment, and judge that the outdoor temperature residing for outdoor environment temperature is interval, control the compressor operating upper frequency limit value that the running frequency of compressor is corresponding less than residing outdoor temperature interval, wherein, carry out, under various operating modes, the compressor operating frequency values that will produce condensation that test obtains when compressor operating upper frequency limit value is that air-conditioner is in corresponding outdoor temperature interval in advance.Thus, the compressor operating upper frequency limit value corresponding less than residing outdoor temperature interval owing to controlling compressor operating frequency, thus, use the control method air-conditioner of the present embodiment will not produce condensation.
The present embodiment as a example by including 6 temperature ranges by outdoor environment temperature, and compressor operating upper frequency limit value corresponding to 6 temperature ranges is as shown in the table:
| Tao(DEG C) | Between outdoor body-sensing ultra-low temperature region | Outdoor body-sensing low-temperature range | Outdoor body-sensing samming is interval | The outdoor comfortable interval of body-sensing | Outdoor body-sensing high temperature is interval | Outdoor body-sensing superhigh temperature is interval |
| Compressor operating upper frequency limit value | Minimum running frequency | F specified * k1 | F specified * k2 | F specified * k3 | F specified * k4 | F specified * k5 |
Wherein, k1 ＜ k2 ＜ k3 ＜ k4 ＜ k5.
Owing to when outdoor body-sensing superhigh temperature interval, compressor typically operates in upper frequency section, now, it is more prone to produce condensation, it is then desired to the compressor operating frequency that outdoor body-sensing superhigh temperature is interval is limited further, as in figure 2 it is shown, control method comprises the steps:
B1, detection outdoor environment temperature Tao are in outdoor body-sensing superhigh temperature interval.
B2, detect draught temperature.
B3, acquisition air conditioner wind speed gear, obtain the air outlet desired temperature that wind-speed gear is corresponding.
B4, control the running frequency of compressor, use draught temperature and reach setting value, use draught temperature and reach the method for setting value and be preferably with air outlet temperature and setting value as parameter, the running frequency of compressor is carried out PID control.
Wherein, setting value is to ensure the air outlet temperature target that air conditioner refrigeration effect is prevented from again condensation.Concrete, as it is shown on figure 3, outdoor environment temperature is when outdoor body-sensing superhigh temperature interval, on the premise of ensureing refrigeration, the PID increasing air outlet temperature controls, and confirms to be possible to prevent the curve 2 of condensation；By refrigeration outer shroud temperature limit frequency test, it is desirable to the indoor set air inlet/outlet temperature difference ensures more than 12 degree, finds out the minimum frequency curve 1 ensured under high-temperature refrigeration effect.By curve 1 and the coupling of curve 2, determine and both can guarantee that high-temperature refrigeration effect, the air outlet temperature target of condensation can be prevented again.
Wherein, the setting value of air outlet temperature is relevant with air conditioner wind speed gear, and wind-speed gear is the highest, and setting value is the lowest.Owing to wind-speed gear is the lowest more easily produces condensation, thus, the quiet gear of air conditioner wind speed gear and the air outlet desired temperature of low wind gear are only defined by the present embodiment, other wind-speed gears are not provided with air outlet desired temperature, with design temperature Ts and indoor temperature Tin, compressor frequency are controlled.The setting value of quiet gear is T1, and the setting value of low wind gear is T2, T1 ＞ T2.
In order to be further ensured that air-conditioner does not produce condensation, each air conditioner wind speed gear is all provided with determining compressor running frequency higher limit by the present embodiment.Control compressor under corresponding wind-speed gear running frequency less than the compressor operating upper frequency limit value of its correspondence.
Design based on above-mentioned air-conditioner condensation prevention control method, the present embodiment also proposed a kind of air-conditioner, air-conditioner is existing conventional common air-conditioning device, i.e. include the air-conditioning of air inlet, air channel, air outlet, certainly, air-conditioner is not limited to above-mentioned common air-conditioning, the air-conditioner in drain air channel is increased on the basis of being particularly additionally included in above-mentioned common air-conditioning, wherein, drain air channel introduces natural wind, the natural wind in drain air channel crosses without heat exchanger heat exchange, the air outlet of the air outlet in drain air channel and air-conditioning self, blowout mixing wind.
Air-conditioner includes that anti-condensation control system, anti-condensation control system include:
Outdoor environment temperature detector unit, is used for detecting outdoor environment temperature Tao, and transmits to control unit；
Control unit, for receiving outdoor environment temperature Tao, judge that the outdoor temperature residing for outdoor environment temperature Tao is interval, read the compressor operating upper frequency limit value that the residing outdoor temperature interval of memory element storage is corresponding, control the compressor operating upper frequency limit value that the running frequency of compressor is corresponding less than residing outdoor temperature interval.When the outdoor environment temperature Tao that control unit receives is in the highest outdoor temperature interval, control unit receives the air outlet temperature of air outlet temperature detecting unit detection, obtain wind-speed gear, read the air outlet desired temperature under the corresponding wind speed party committee of memory element storage, control the running frequency of compressor, using draught temperature and reach setting value, wherein, setting value is to ensure the air outlet temperature target that air conditioner refrigeration effect is prevented from again condensation；
Air outlet temperature detecting unit, is used for detecting draught temperature and transmitting to control unit；
