Referring to Fig. 1-Fig. 2, the control method according to the air-conditioner of the embodiment of the present invention is described.
It should be noted that, for those of ordinary skills, air-conditioner comprises the parts such as compressor, outdoor heat exchanger, restricting element and indoor heat exchanger, the annexation between above-mentioned parts, the refrigeration of air-conditioner and to heat principle etc. be all known, is not just described in detail here.
With reference to shown in Fig. 1, according to the control method of the air-conditioner of the embodiment of the present invention, comprise the steps:
S1: control air-conditioner and open and be in refrigerating operaton, now, compressor can carry out work with certain frequency, refrigerant is by after outdoor heat exchanger heat exchange, and through the reducing pressure by regulating flow of restricting element, in indoor heat exchanger, evaporation endothermic is to lower the temperature to indoor environment, when compressor is with high-frequency work, the refrigeration of air-conditioning is better, and when compressor is with low frequency operation, the refrigeration of air-conditioning reduces.
S2: detect outdoor environment temperature T1, and by outdoor environment temperature T1 and design temperature value range (T11, T22] compare, to determine whether to enter cryogenic refrigeration pattern, that is, when air-conditioner in cooling mode, can detect outdoor environment temperature T1 simultaneously.Particularly, temperature sensor can be adopted to detect outdoor environment temperature T1.
S3: when outdoor environment temperature T1 be positioned at value range is set time, air-conditioner enters cryogenic refrigeration pattern, if not, then continue to compare, that is, if the temperature range value (T11 that outdoor environment temperature T1 does not make air-conditioner enter cryogenic refrigeration pattern, T22] interior time, air-conditioner also detects outdoor environment temperature T1 under being still in normal refrigeration mode always, until detect that outdoor environment temperature T1 is at temperature range value (T11, T22] interior time, now, air-conditioner will enter cryogenic refrigeration pattern.
S4: in cryogenic refrigeration pattern, design temperature value range is divided into multiple subinterval, according to the child partition belonging to the outdoor environment temperature T1 detected, regulate the running frequency of compressor, the running frequency of the compressor that each child partition is corresponding is different, the temperature that the running frequency of compressor is corresponding with child partition is proportionate, such as, in concrete examples more of the present invention, shown in figure 2, when T1 is (20, 10] time in scope, the operating frequency of compressor is 66Hz, when T1 is (10, 0] time in scope, the operating frequency of compressor is 60Hz, when T1 is (0,-10] time in scope, the operating frequency of compressor is 54Hz, that is, when air-conditioner enters cryogenic refrigeration pattern, the temperature of the child partition belonging to outdoor environment temperature T1 is lower, the operating frequency of compressor is lower, the refrigeration of air-conditioner will decline gradually, thus air-conditioner under lower outdoor environment temperature T1 can be avoided to occur freezing, compressor returns the phenomenons such as liquid.Wherein, in cryogenic refrigeration pattern, when exit criteria being detected, exit cryogenic refrigeration pattern.
According to the control method of the air-conditioner of the embodiment of the present invention, determine whether to enter cryogenic refrigeration pattern by the outdoor environment temperature T1 detected, again according to the child partition belonging to outdoor environment temperature T1 detected, regulate the running frequency of compressor, the running frequency of the compressor that each child partition is corresponding is different, the temperature that the running frequency of compressor is corresponding with child partition is proportionate, thus the frequency of compressor is controlled, and then effectively can regulate the work requirements of air-conditioner, efficiently solve that indoor set under low temperature environment freezes, compressor returns the technical problems such as liquid.
According to the control method of the air-conditioner of the embodiment of the present invention, also comprise the steps:
S5: in cryogenic refrigeration pattern, detect indoor environment temperature T2, the difference DELTA T and first of indoor environment temperature T2 and design temperature Ts is set difference DELTA t1 compare, that is, when outdoor environment temperature T1 is positioned at a subinterval, the operating frequency of compressor neither be changeless, need that the difference DELTA T and first of indoor environment temperature T2 and design temperature Ts is set difference DELTA t1 to compare, thus the operating frequency adjusting compressor is further to meet actual refrigeration demand better.
S6: when difference DELTA T is less than the first setting difference DELTA t1, reduces the frequency of compressor.Be understandable that, along with air-conditioner is in cryogenic refrigeration pattern always, indoor environment temperature T2 constantly reduces, the difference DELTA T of indoor environment temperature T2 and design temperature Ts also reduces gradually, now the refrigeration demand of air-conditioner to indoor environment also reduces gradually, thus when difference DELTA T is less than the first setting difference DELTA t1, need the frequency reducing compressor further, while ensureing the refrigeration demand that air-conditioner is lower, avoid compressor operating frequency higher cause indoor heat exchanger freeze etc. problem, and can the operating efficiency of raising air-conditioner effectively, reduce use cost.
Further; when the frequency of compressor is reduced to predetermined value fmin; compressor shutdown; that is; when difference DELTA T is less than the first setting difference DELTA t1 always; the frequency of compressor can reduce always gradually, until when the frequency of compressor is reduced to predetermined value fmin, compressor cuts out and quits work.
Further, after compressor shutdown, when the difference DELTA T of indoor environment temperature T2 and design temperature Ts is greater than the second setting difference DELTA t2, compressor start also gets back to step S2.Quit work along with compressor cuts out, air-conditioner to indoor environment without refrigeration, now indoor environment temperature T2 can raise gradually, when indoor environment temperature T2 is elevated to a certain degree, now, reset itself work is just needed to freeze to indoor environment, that is, when the difference DELTA T of indoor environment temperature T2 and design temperature Ts is greater than the second setting difference DELTA t2, compressor start, and get back to S2 step;
It should be noted that, design temperature value range (T11, T22], first setting difference DELTA t1, predetermined value fmin, second setting difference DELTA t2 concrete numerical value can set as the case may be, be just not specifically limited at this.
Particularly, exit criteria is for detecting that outdoor environment temperature T1 is positioned at outside design temperature value range, that is, under the pattern that air-conditioner cryogenic refrigeration runs, once detect outdoor environment temperature T1 not design temperature value range (T11, T22] in, then air-conditioner exits cryogenic refrigeration pattern, and air-conditioner can detect outdoor environment temperature T1 always, to judge when need again to enter cryogenic refrigeration pattern.
In some embodiments of the invention, in step s 4 which, according to the child partition belonging to the outdoor environment temperature T1 detected, regulate the rotating speed of outdoor fan, the temperature that wherein rotating speed of outdoor fan is corresponding with child partition is proportionate.Such as, shown in figure 2, when T1 is (20, 10] time in scope, indoor fan rotating speed can be 700r/min, when T1 is (10, 0] time in scope, indoor fan rotating speed can be 600r/min, when T1 is (0,-10] time in scope, indoor fan rotating speed can be 500r/min, that is, when air-conditioner enters cryogenic refrigeration pattern, the temperature in the subinterval belonging to outdoor environment temperature T1 is lower, indoor fan rotating speed also can little by little reduce, thus the refrigeration of air-conditioner can be reduced, under meeting refrigeration demand situation, improve the operating efficiency of air-conditioner, air-conditioner is avoided to occur phenomenons such as freezing.
In some embodiments of the invention, in step s 4 which, according to the child partition belonging to the outdoor environment temperature T1 detected, regulate the aperture of restricting element, such as, shown in figure 2, when T1 is (20, 10] time in scope, the aperture of restricting element can be 180 steps, when T1 is (10, 0] time in scope, the aperture of restricting element can be 210 steps, when T1 is (-10,-20] time in scope, the aperture of restricting element can be 250 steps, that is, when air-conditioner enters cryogenic refrigeration pattern, the temperature in the subinterval belonging to outdoor environment temperature T1 is lower, the aperture step number of restricting element gradually changes, thus effectively can control the flow of refrigerant, and then meet refrigeration demand, avoid the situation occurring that refrigeration is excessive.
Further, restricting element is electric expansion valve, and electric expansion valve can control the flow of refrigerant in refrigerant flow accurately, guarantees the stability of freezing, and improves the job stability of air-conditioner.
Below with reference to Fig. 1-Fig. 2, a specific embodiment of the control method according to air-conditioner of the present invention is described.
S1: when user starts shooting, selects refrigeration mode;
S2: Real-time Obtaining outdoor environment temperature T1=8 DEG C, now T1 meets cryogenic refrigeration condition T1<20 DEG C, enters cryogenic refrigeration pattern;
S3: the subregion judging T1 place, T1=8 DEG C belong to (10,0] subregion, control compressor frequency 60Hz, outdoor fan rotating speed 600r/min, electronic expansion valve opening 210 step;
S4: if Real-Time Monitoring indoor environment temperature T2=19 DEG C, with the difference DELTA T=2 DEG C of < Δ t1=4 DEG C of design temperature Ts=17 DEG C, compressor reduces frequency 2Hz;
S5: continuation steps S4, the frequency of compressor declines gradually, when compressor frequency reaches a certain particular value during fmin=0.1Hz, and compressor shutdown;
S6: when indoor environment temperature T2=20 DEG C with the difference DELTA T=3 DEG C >=Δ t2=3 DEG C of design temperature Ts=17 DEG C, compressor start also carries out judgement with above-mentioned steps S2 and runs.
Wherein, when outdoor environment temperature T1 >=20 DEG C, cryogenic refrigeration pattern is exited.
It can thus be appreciated that, determine whether to enter cryogenic refrigeration pattern by the outdoor environment temperature T1 detected, again according to the child partition belonging to outdoor environment temperature T1 detected, regulate the running frequency of compressor, detect indoor environment temperature T2 further afterwards, the difference DELTA T and first of indoor environment temperature T2 and design temperature Ts is set difference DELTA t1 and second to set difference DELTA t2 and compare, the frequency of compressor is controlled, thus effectively regulate the work requirements of air-conditioner, efficiently solve that indoor set under low temperature environment freezes, compressor returns the technical problems such as liquid.
