본 발명은 실내 온도에 따라 압축기의 운전주파수를 변화시켜서 공기조화기의 능력 그 차체를 직접 제어하는 인버터 공기조화기에 관한 것으로, 특히 초기 난방운전시 실외온도가 낮아 난방부하가 증가됨으로 인해 압축기에 과부하가 걸리는 것과 냉매진동으로 인해 경화상태의 배관에서 소음이 발생하는 것을 방지하기 위한 인버터 공기조화기의 초기 난방운전시 압축기 제어방법에 관한 것이다.The present invention relates to an inverter air conditioner that directly controls the vehicle body's capability by varying the operating frequency of the compressor according to the room temperature. Particularly, the initial load is overloaded due to the increase in the heating load due to the low outdoor temperature. The present invention relates to a control method of a compressor during an initial heating operation of an inverter air conditioner for preventing noise from being generated in a hardened pipe due to a vibration of a refrigerant and a vibration of a refrigerant.

종래 인버터 공기조화기의 난방운전시 최고운전주파수 제어에 의한 압축기 제어방법은 제1도에 나타낸 바와 같다.The compressor control method by controlling the maximum operating frequency during the heating operation of the conventional inverter air conditioner is shown in FIG.

먼저, 제1도의 (a)에 나타난 난방운전시 압축기 제어방법을 살펴보면, 난방운전이 온되면 실내온도 검출센서로부터 입력된 실내온도와 사용자에 의해 설정된 실내온도인 설정온도에 따라 기 저장된 압축기 운전주파수로부터 현재 실내온도와 설정온도에 해당되는 압축기의 운전주파수를 설정한다.First, referring to the method of controlling a compressor during heating operation shown in (a) of FIG. 1, when the heating operation is turned on, the compressor operating frequency is stored according to the indoor temperature input from the indoor temperature detection sensor and the preset temperature set by the user. Set the operating frequency of the compressor corresponding to the current room temperature and the set temperature from.

그 다음, 실외온도 검출센서로부터 입력되는 실외온도(T)가 다단계로 구분된 실외온도구간의 어느 구간에 해당되는지를 판단하고, 실외온도(T)가 낮을수록 난방부하가 증가하므로 이에 대응하여 난방능력(압축기의 능력)을 증가시키기 위해서 실외온도(T)가 낮은 단계일수록 압축기의 최고운전주파수를 높게 설정한다. 여기서 최고운전주파수는 압축기에 과부하가 걸리지 않는 압축기의 최고주파수로써, 실외온도(T)에 따라 압축기의 최고운전주파수를 각각 설정하여 압축기의 과부하를 방지하기 위한 것이다.Next, it is determined which section of the outdoor temperature section that the outdoor temperature T input from the outdoor temperature detection sensor is divided into, and the heating load increases as the outdoor temperature T is lower. In order to increase the capacity (compressor capacity), the lower the outdoor temperature T is set, the higher the maximum operating frequency of the compressor. Here, the maximum operating frequency is the maximum frequency of the compressor that does not overload the compressor, to set the maximum operating frequency of the compressor according to the outdoor temperature (T) to prevent the overload of the compressor.

예를 들면, 실외온도(T)가 20℃이상이면(T≥20℃) 최고운전주파수를 62㎐로 설정하고, 실외온도(T)가 12℃이상이면서 20℃ 보다 작으면(12≤T20) 최고운전주파수를 72㎐로 설정하고, 실외온도(T)가 -4.9℃이상이면서 12℃ 보다 작으면(-4.9≤T12) 최고운전주파수를 86㎐로 설정한다.For example, when the outdoor temperature T is 20 ° C or higher (T≥20 ° C), the maximum operating frequency is set to 62 Hz, and when the outdoor temperature T is 12 ° C or higher and smaller than 20 ° C (12≤T20). Set the maximum operating frequency to 72 kHz, and set the maximum operating frequency to 86 으면 when the outdoor temperature (T) is above -4.9 ℃ and less than 12 ℃ (-4.9≤T12).

그 다음, 상기 실내온도와 설정온도에 의해 설정된 압축기 운전주파수로 압축기를 운전하다가 상기 압축기 운전주파수가 최고운전주파수 보다 높아지면 압축기를 최고운전주파수로 운전하는 것으로, 이것은 압축기가 최고운전주파수 보다 높은 주파수로 운전되지 않도록 하여 압축기의 과부하를 방지한다.Then, the compressor is operated at the compressor operating frequency set by the room temperature and the set temperature, and when the compressor operating frequency is higher than the maximum operating frequency, the compressor is operated at the highest operating frequency, which is a frequency higher than the maximum operating frequency. To prevent overload of the compressor.

그러나 상기한 종래 난방운전시 압축기 제어방법은 실외온도가 -4.9℃ 이상에서는 압축기의 과부하를 방지하기 위해 최고운전주파수가 설정되어 있지만 실외온도가 -4.9℃ 보다 낮아져서 난방부하가 증가됨에 따라 실제적으로 압축기가 고주파수로 운전되는 경우 압축기의 최고운전주파수가 설정되어 있지 않기 때문에 실외온도가 -4.9℃ 보다 낮은 경우 실내온도와 설정온도에 의해 결정되는 운전주파수에 의해서 압축기가 운전되어 압축기의 과부하를 방지하지 못하고, 낮은 실외온도에 의해서 경화상태(단단히 굳어서 인장력이 적은 상태)인 배관에 안정되지 않는 냉매가 공급되어 냉매에 의한 진동으로 소음이 발생하는 문제점이 있었다.However, in the conventional heating operation, the compressor control method has a maximum operating frequency in order to prevent overload of the compressor when the outdoor temperature is higher than -4.9 ℃, but the compressor is practically increased as the heating load increases because the outdoor temperature is lower than -4.9 ℃. Is operating at high frequency, the maximum operating frequency of the compressor is not set. If the outdoor temperature is lower than -4.9 ℃, the compressor is operated by the operating frequency determined by the indoor temperature and the set temperature. There is a problem in that noise is generated due to vibration caused by the coolant which is supplied to the unstable coolant to the pipe in a hardened state due to the low outdoor temperature.

또한, 제1도의 (b)에 나타난 인버터 공기조화기의 난방운전시 보정주파수 제어에 의한 압축기 제어방법을 살펴보면, 난방운전이 온되어 일정시간 동안은 초기 난방운전을 하게 되는데, 실내온도와 사용자에 의해 설정된 실내온도인 설정온도에 따라 압축기의 운전주파수를 설정한다.In addition, the compressor control method by the correction frequency control during the heating operation of the inverter air conditioner shown in (b) of FIG. 1 shows that the heating operation is turned on and the initial heating operation is performed for a predetermined time. The operating frequency of the compressor is set according to the set temperature which is the room temperature set by the controller.

그 다음, 실외온도 검출센서로부터 입력되는 실외온도(T)가 다단계로 구분된 실외온도구간의 어느 구간에 해당되는지를 판단하고, 실외온도(T)가 낮을수록 난방부하가 증가하므로 이를 위해 실외온도(T)가 낮은 단계일수록 압축기 운전주파수를 보정하기 위한 보정주파수를 높게 설정한다. 상기 보정주파수는 초기 난방운전시 실외온도에 따라 압축기에 운전주파수를 보정하여 난방능력을 향상시키기 위한 것이다.Next, it is determined which section of the outdoor temperature section, which is input from the outdoor temperature detection sensor, is divided into multiple stages, and the lower the outdoor temperature T, the heating load increases. The lower the step (T), the higher the correction frequency for correcting the compressor operating frequency. The correction frequency is to improve the heating capacity by correcting the operating frequency in the compressor according to the outdoor temperature during the initial heating operation.

예를 들면, 제1설정온도(T1)가 제2설정온도(T2) 보다 높고(T1T2), 보정주파수중 최저주파수를 a㎐, 중간주파수를 b㎐, 최고주파수를 c㎐로 한다(abc). 실외온도(T)가 제1설정온도(T1) 이상이면 (T≥T1℃) 보정주파수를 최저주파수(aH2)로 설정하고, 실외온도(T)가 제2설정온도(T2) 이상이면서 제1설정온도(T1) 보다 작으면(T2≤TT1) 보정주파수를 중간주파수(b㎐)로 설정하고, 실외온도(T)가 제2설정온도(T2) 보다 작으면(TT2) 보정주파수를 최고주파수(c㎐)로 설정한다.For example, the first set temperature T1 is higher than the second set temperature T2 (T1T2), and the minimum frequency among the correction frequencies is a㎐, the middle frequency is b㎐, and the maximum frequency is c㎐ (abc). . If the outdoor temperature T is equal to or greater than the first set temperature T1, the correction frequency (T≥T1 ° C.) is set to the lowest frequency aH 2 , and the outdoor temperature T is equal to or greater than the second set temperature T2. If the temperature is less than one set temperature (T1) (T2≤TT1), the correction frequency is set to the intermediate frequency (b (), and if the outdoor temperature (T) is less than the second set temperature (T2) (TT2), the correction frequency is the highest. Set to frequency (c㎐).

그 다음, 상기 실내온도와 설정온도에 의해 설정된 압축기 운전주파수와 보정주파수의 합으로 압축기를 고속회전시키게 된다. 즉, 실외온도가 낮을수록 증가되는 난방부하에 대응하기 위해 높은 보정주파수로 운전주파수를 보정하여 압축기를 운전하므로 초기 난방운전시 난방능력을 향상시키게 된다.Then, the compressor is rotated at high speed by the sum of the compressor operating frequency and the correction frequency set by the room temperature and the set temperature. That is, as the outdoor temperature is lowered, the compressor is operated by correcting the operating frequency with a high correction frequency to cope with the increased heating load, thereby improving the heating capacity during the initial heating operation.

그러나 상기한 종래 초기 난방운전시 압축기 제어방법은 실외온도가 낮을수록 보정주파수를 높여서 실내온도와 설정온도에 따라 설정된 운전주파수를 보정하는 것으로, 초기 난방운전시 실외온도가 낮을수록 초기 압축기를 높은 주파수로 운전하기 때문에 급작스런 고주파 운전으로 인해 압축기에 과전류가 유입되어 고장의 원인이 되고, 낮은 실외온도로 인해 경화상태의 배관에 냉매가 갑작스럽게 공급되어 냉매흐름이 안정되기 전까지 냉매의 진동으로 인해 소음이 발생되고 심한 경우에는 상기 냉매의 과도한 진동으로 인해 배관이 손상되는 문제점이 있었다.However, the conventional control method of the compressor during the initial heating operation is to correct the operation frequency set according to the indoor temperature and the set temperature by increasing the correction frequency as the outdoor temperature is low, and the initial frequency by the initial compressor when the outdoor temperature is low during the initial heating operation. Because of the sudden high frequency operation, the overcurrent flows into the compressor, causing the failure, and due to the low outdoor temperature, the refrigerant is suddenly supplied to the hardened pipe and the noise is caused by the vibration of the refrigerant until the flow of the refrigerant is stabilized. In the severe case, the pipe is damaged due to excessive vibration of the refrigerant.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 특히 초기 난방운전시 실외온도에 따라 압축기의 최고운전주파수를 설정하여 압축기에 과부하가 걸리는 것을 방지하고, 초기 난방운전시 압축기의 주파수를 다단계로 증가시켜서 압축기에 과부하가 걸리는 것을 방지하고 냉매흐름을 안정시켜서 경화상태의 배관의 소음을 방지하기 위한 인버터 공기조화기의 초기 난방운전시 압축기 제어방법을 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, in particular to set the maximum operating frequency of the compressor according to the outdoor temperature during the initial heating operation to prevent the compressor from being overloaded, the frequency of the compressor during the initial heating operation It is to provide a control method of the compressor during the initial heating operation of the inverter air conditioner to prevent the overload of the compressor by increasing the multi-step and to stabilize the refrigerant flow to prevent the noise of the hardened pipe.

이하 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.

본 발명 인버터 공기조화기의 초기 난방운전시 압축기 제어방법의 제1구성예는 난방운전이 온되면 실내온도 검출센서로부터 입력된 실내온도와 사용자에 의해 설정된 실내온도인 설정온도에 따라 기 저장된 압축기 운전주파수로부터 압축기의 운전주파수를 설정하는 인버터 공기조화기의 난방운전시 압축기 제어방법에 있어서, 상기 운전주파수를 설정한 다음, 실외온도 검출센서로부터 입력된 실외온도가 다수 개로 구분된 실외온도구간중 어느 구간에 해당되는지를 판단하고, 상기 실외온도가 소정의 실외제어온도 이상인 실외온도구간에 속하는지를 판단하는 실외온도 판단단계와, 실외온도가 실외제어온도 이상인 실외온도구간에 속하는 경우에는 실외온도가 낮은 온도의 실외온도구간에 해당될수록 난방부하의 증가에 대응하여 난방능력을 증가시키기 위해서 압축기 과부하상태 전의 압축기 최고주파수인 최고운전주파수를 높게 설정하는 최고운전주파수 제1설정단계와, 실외온도가 상기 실외제어온도 보다 낮은 실외온도구간에 속하는 경우에는 실외온도가 낮은 온도의 실외온도구간에 속할수록 최고운전주파수를 낮게 설정하는 최고운전주파수 제2설정단계로 된 최고운전주파수 설정단계와; 상기 최고운전주파수 제1설정단계를 수행한 후, 실내온도와 설정온도에 따라 설정된 상기 압축기의 운전주파수로 압축기를 운전하다가 상기 압축기 운전주파수가 상기 최고운전주파수 보다 높은 경우 압축기를 최고운전주파수로 운전하는 제1압축기 운전단계와, 상기 최고운전주파수 제2설정단계를 수행한 후, 압축기를 상기 최고운전주파수로 운전하되 실외온도가 낮은 온도의 실외온도구간에 속할수록 긴 소정시간 운전한 다음, 실내온도와 설정온도에 따라 설정된 상기 압축기의 운전주파수로 압축기를 운전하는 제2압축기 운전단계로 된 압축기 운전단계를 포함하여 구성되는 것을 특징으로 한다.The first configuration example of the compressor control method during the initial heating operation of the inverter air conditioner according to the present invention is the pre-stored compressor operation according to the indoor temperature input from the indoor temperature detection sensor and the preset temperature set by the user when the heating operation is turned on.

And a compressor operating step including a second compressor operating step of operating the compressor at an operating frequency of the compressor set according to a temperature and a set temperature.

먼저, 운전주파수 설정단계(S10)에서 난방운전이 온되면 실내온도 검출센서로부터 입력된 실내온도와 사용자에 의해 설정된 실내온도인 설정온도에 따라 기 저장된 압축기 운전주파수 데이타로부터 압축기의 운전주파수를 설정한다.First, when the heating operation is turned on in the operation frequency setting step (S10), the operation frequency of the compressor is set from the stored compressor operation frequency data according to the indoor temperature input from the indoor temperature detection sensor and the set temperature which is the indoor temperature set by the user. .

상기 운전주파수 설정단계(S10)를 수행한 후, 최고운전주파수 설정단계(S20)중 실외온도 판단단계(S21)에서 실외온도 검출센서로부터 입력된 실외온도(T)가 다수개로 구분된 실외온도구간중 어느 구간에 해당되는지를 판단하고, 실외온도(T)가 소정의 실외제어온도(-4.9℃) 이상인 실외온도구간에 속하는지 아닌지를 판단한다.After performing the operation frequency setting step (S10), the outdoor temperature section is divided into a plurality of outdoor temperature (T) input from the outdoor temperature detection sensor in the outdoor temperature determination step (S21) of the maximum operating frequency setting step (S20). It is determined whether or not it corresponds to any of the sections, and whether or not the outdoor temperature (T) belongs to the outdoor temperature section of the predetermined outdoor control temperature (-4.9 ℃) or more.

상기 판단결과 실외온도(T)가 상기 실외제어온도(-4.9℃) 이상인 실외온도구간에 속하는 경우, 최고운전주파수 제1설정단계(S22)에서 실외온도(T)가 낮은 온도의 실외온도구간에 속할수록 압축기 과부하상태에 들어가기 전 압축기 최고주파수인 최고운전주파수를 높게 설정하여 난방부하의 증가에 대응하여 난방능력을 증가시키게 된다.As a result of the determination, when the outdoor temperature T belongs to the outdoor temperature section of which the outdoor control temperature (-4.9 ° C.) or more is reached, the outdoor temperature section of the outdoor temperature T having a low outdoor temperature T is set in the first operation step S22. The higher the operating frequency, the higher the maximum operating frequency of the compressor before entering the compressor overload condition increases the heating capacity in response to the increase in the heating load.

예를 들면, 실외온도(T)가 20℃이상이면(T≥20℃), 실외온도(T)가 12℃이상이면서 20℃ 보다 작으면(12≤T20), 실외온도(T)가 -4.9℃이상이면서 12℃보다 작은 경우(-4.9≤T12)는 모두 실외온도(T)가 실외제어온도(-4.9℃) 이상이므로 실외온도(T)가 낮을수록 최고운전주파수를 높게 설정한다. 즉, 실외온도(T)가 20℃이상인 경우(T≥20℃) 최고운전주파수를 59㎐로, 실외온도(T)가 12℃이상이면서 20℃ 보다 작은 경우(12≤T20) 최고운전주파수를 73㎐로, 실외온도(T)가 -4.9℃ 이상이면서 12℃ 보다 작은 경우(-4.9≤T12) 최고운전주파수를 83㎐로 설정한다.For example, if the outdoor temperature T is 20 ° C or more (T≥20 ° C), if the outdoor temperature T is 12 ° C or more and less than 20 ° C (12≤T20), the outdoor temperature T is -4.9. If the temperature is higher than ℃ but lower than 12 ℃ (-4.9≤T12), the outdoor temperature T is higher than the outdoor control temperature (-4.9 ℃). Therefore, the lower the outdoor temperature T is, the higher the maximum operating frequency is set. That is, when the outdoor temperature (T) is 20 ° C or higher (T≥20 ° C), the maximum operating frequency is 59 Hz, and when the outdoor temperature (T) is 12 ° C or higher and lower than 20 ° C (12≤T20), the maximum operating frequency is If the outdoor temperature T is less than -4.9 ° C but less than 12 ° C (-4.9≤T12), the maximum operating frequency is set to 83㎐.

또한, 상기 판단결과 실외온도(T)가 상기 실외제어온도(-4.9℃) 보다 낮은 실외온도구간에 속하는 경우, 최고운전주파수 제2설정단계(S23)에서 실외온도(T)가 낮은 온도의 실외온도구간에 속할수록 최고운전주파수를 낮게 설정하여 압축기를 보호한다.In addition, when the determination result that the outdoor temperature (T) belongs to the outdoor temperature section lower than the outdoor control temperature (-4.9 ℃), the outdoor temperature of the outdoor temperature (T) is low in the second operation step (S23) of the highest operating frequency The higher the temperature range, the lower the maximum operating frequency to protect the compressor.

예를 들면, 실외온도(T)가 -10℃이상이면서 -4.9℃ 보다 작은 경우(-10≤T-4.9)와 실외온도(T)가 -10℃ 보다 작은 경우(T-10)는 모두 실외온도(T)가 실외제어온도(-4.9℃) 보다 낮으므로 실외온도(T)가 낮을수록 최고운전주파수를 낮게 설정한다. 즉, 실외온도(T)가 -10℃이상이면서 -4.9℃ 보다 작은 경우(-10≤T-4.9) 최고운전주파수를 48㎐로, 실외온도(T)가 -10℃ 보다 작은 경우(T-10) 최고운전주파수를 35㎐로 설정한다.For example, when the outdoor temperature (T) is more than -10 ° C but less than -4.9 ° C (-10≤T-4.9) and the outdoor temperature (T) is less than -10 ° C, both outdoor Since the temperature T is lower than the outdoor control temperature (-4.9 ° C.), the lower the outdoor temperature T is, the lower the maximum operating frequency is set. That is, when the outdoor temperature (T) is above -10 ° C but lower than -4.9 ° C (-10≤T-4.9), the maximum operating frequency is 48㎐, and the outdoor temperature (T) is lower than -10 ° C (T- 10) Set the maximum operating frequency to 35 kHz.

이와 같이 최고운전주파수 설정단계(S20)를 수행한 후, 압축기 운전단계(S30)에서는 상기 운전주파수 설정단계(S10)에서 실내온도와 설정온도에 따라 설정된 압축기의 운전주파수와 최고운전주파수 설정단계(S20)에서 설정된 최고운전주파수를 이용하여 압축기를 운전하게 된다.After performing the maximum operation frequency setting step (S20) as described above, in the compressor operation step (S30), the operation frequency and the maximum operation frequency setting step of the compressor set according to the room temperature and the set temperature in the operation frequency setting step (S10) ( The compressor is operated using the highest operating frequency set in S20).

즉, 상기 최고운전주파수 제1설정단계(S22)를 수행한 경우 제1압축기 운전단계(S31)에서, 실내온도와 설정온도에 따라 설정된 상기 압축기의 운전주파수로 압축기를 운전하다가 상기 압축기 운전주파수가 상기 설정된 최고운전주파수 보다 높은 경우 압축기를 최고운전주파수로 운전하여 압축기가 최고운전주파수 이상으로 운전되는 것을 방지하므로 압축기에 과부하가 걸리는 것을 방지한다.That is, when the first operation step (S22) of the highest operating frequency is performed, in the first compressor operation step (S31), the compressor is operated at the operating frequency of the compressor set according to the room temperature and the set temperature, and the compressor operation frequency is increased. If it is higher than the set maximum operating frequency, the compressor is operated at the highest operating frequency, thereby preventing the compressor from operating above the maximum operating frequency, thereby preventing the compressor from being overloaded.

또한, 상기 최고운전주파수 제2설정단계(S23)를 수행한 경우, 제2압축기 운전단계(S32)에서, 압축기를 상기 설정된 최고운전주파수로 소정시간 운전한 다음, 압축기를 상기 운전주파수로 운전을 한다. 여기에서 실외온도(T)가 낮은 온도의 실외온도구간에 속할수록 상기 최고운전주파수로 압축기를 운전하는 소정시간을 길게하여, 실외온도(T)가 -10℃이상이면서 -4.9℃ 보다 작은 경우 (-10≤T-4.9) 최고운전주파수(48㎐)로 30분 운전하고, 실외온도(T)가 -10℃ 보다 작은 경우(T-10) 최고운전주파수(35㎐)로 60분 운전한다.In addition, in the case of performing the second setting step S23 of the highest operating frequency, in operation S32 of the second compressor, the compressor is operated at the set maximum operating frequency for a predetermined time, and then the compressor is operated at the operating frequency. do. Herein, when the outdoor temperature T belongs to a low temperature outdoor temperature section, the predetermined time for operating the compressor at the maximum operating frequency is increased, and the outdoor temperature T is -10 ° C. or more and less than -4.9 ° C. ( -10≤T-4.9) Operate for 30 minutes at the highest operating frequency (48Hz), and operate for 60 minutes at the highest operating frequency (35kHz) when the outdoor temperature (T) is less than -10 ℃ (T-10).

이에 따라, 실외온도(T)가 많이 낮은 경우, 먼저 압축기를 소정시간 동안 저주파수로 운전하여 압축기를 과부하로부터 보호하고 냉매흐름을 어느 정도 안정시킨 상태에서 압축기를 운정주파수인 고주파수로 운전하므로 난방부하에 대응되는 난방능력을 낼 수 있을 뿐만 아니라 낮은 실외온도(T)로 경화상태인 배관에 흐르는 냉매로 인한 진동을 방지하여 소음을 방지할 수 있다.Accordingly, when the outdoor temperature T is very low, the compressor is operated at a low frequency for a predetermined time to protect the compressor from overload and operate the compressor at a high frequency of operating frequency while the refrigerant flow is stabilized to a certain degree. In addition to providing a corresponding heating capacity, it is possible to prevent noise by preventing vibration caused by a refrigerant flowing in a pipe which is hardened at a low outdoor temperature (T).

한편, 본 발명 제2구성예를 제3도를 참조하여 상세히 설명하면 다음과 같다.On the other hand, the second configuration example of the present invention will be described in detail with reference to FIG.

먼저, 운전주파수 설정단계(S10)에서 난방운전이 온되면 실내온도 검출센서로부터 입력된 실내온도와 사용자에 의해 설정된 실내온도인 설정온도에 따라 기 저장된 압축기 운전주파수 데이터로부터 압축기의 운전주파수를 설정한다.First, when the heating operation is turned on in the operation frequency setting step (S10), the operation frequency of the compressor is set from the stored compressor operation frequency data according to the indoor temperature input from the indoor temperature detection sensor and the set temperature which is the indoor temperature set by the user. .

상기 운전주파수 설정단계(S10)를 수행한 후, 보정 주파수 설정단계(S40)에서 실외온도 검출센서로부터 입력된 실외온도(T)가 다수 개로 구분된 실외온도구간중 어느 구간에 해당되는지를 판단하고, 실외온도(T)가 낮을수록 난방부하가 증가하는데 대응하여 난방능력을 증가시키기 위해 실외온도(T)가 낮은 온도의 실외온도구간에 속할 수록 다단계로 나누어진 보정주파수중 높은 주파수를 보정주파수로 설정한다.After performing the operation frequency setting step (S10), it is determined in which section of the outdoor temperature section divided into a plurality of outdoor temperature (T) input from the outdoor temperature detection sensor in the correction frequency setting step (S40) and In order to increase the heating capacity in response to a lower outdoor temperature (T), the higher frequency of the correction frequency divided into multiple stages as the correction frequency as the outdoor temperature (T) belongs to the low temperature outdoor temperature section. Set it.

예를 들면, 보정주파수는 다단계로 나눌 수 있으며, 이하 보정주파수를 최저주파수, 중간주파수, 최고주파수의 3단계로 나눈 경우에 대해 설명하면, 실외온도(T)가 제1설정온도(T1) 이상이면(T≥T1℃) 보정주파수를 최저주파수로 설정하고, 실외온도(T)가 제2설정온도(T2) 이상이면서 제1설정온도(T1)보다 작으면(T2≤TT1) 보정주파수를 중간주파수로로 설정하고, 실외온도(T)가 제2설정온도(T2) 보다 작으면(TT2) 보정주파수를 최고주파수로 설정한다.For example, the correction frequency may be divided into multiple stages. Hereinafter, a case in which the correction frequency is divided into three stages of the lowest frequency, the intermediate frequency, and the highest frequency will be described. The outdoor temperature T is greater than or equal to the first set temperature T1. If (T≥T1 ℃) the correction frequency is set to the lowest frequency and the outdoor temperature (T) is higher than the second set temperature (T2) but smaller than the first set temperature (T1) (T2≤TT1), the correction frequency is intermediate. If the frequency is set to a frequency and the outdoor temperature T is smaller than the second set temperature T2 (TT2), the correction frequency is set to the maximum frequency.

상기 보정주파수 설정단계(S40)를 수행한 후, 압축기 운전 안정단계(S50)에서 상기 운전주파수와 보정주파수의 합으로 압축기를 운전하되, 상기 보정주파수는 먼저, 낮은 단계의 보정주파수로 설정한 상태에서 소정시간 간격으로 상기 보정주파수를 그 다음 높은 단계의 보정주파수로 재 설정하는 것을 상기 보정주파수가 상기 보정주파수 설정단계(S40)에서 설정된 보정주파수까지 증가되도록 반복하여 압축기의 주파수를 점차적으로 증가시키면서 운전한다.After performing the correction frequency setting step (S40), the compressor is operated by the sum of the operating frequency and the correction frequency in the compressor operation stabilization step (S50), but the correction frequency is first set to a low level correction frequency. Resetting the correction frequency to the next higher correction frequency at predetermined time intervals, repeating so that the correction frequency is increased to the correction frequency set in the correction frequency setting step (S40) while gradually increasing the frequency of the compressor. Drive.

예를 들면, 상기 보정주파수 설정단계(S40)에서 설정된 보정주파수가 중간주파수로 설정된 경우, 먼저 보정주파수를 최소주파수에 해당되는 a㎐로 하여 소정시간(t1) 동안 운전주파수와 보정주파수(a㎐)의 합으로 압축기를 운전한 후, 보정주파수를 중간주파수에 해당되는 b㎐로 하여 소정시간(t2) 동안 운전주파수와 보정주파수(b㎐)의 합으로 압축기를 운전한다.For example, when the correction frequency set in the correction frequency setting step (S40) is set to the intermediate frequency, first the operating frequency and the correction frequency (a 하여) for a predetermined time (t1) with the correction frequency as a 해당 corresponding to the minimum frequency. After the compressor is operated with the sum of), the compressor is operated at the sum of the operating frequency and the correction frequency (b 동안) for a predetermined time t2 with the correction frequency being b㎐ corresponding to the intermediate frequency.

또한, 상기 보정주파수 설정단계(S40)에서 설정된 보정주파수가 최고주파수로 설정된 경우, 보정주파수를 최소주파수에 해당되는 a㎐로, 중간주파수에 해당되는 b㎐로, 최고주파수에 해당되는 c㎐로 각각 소정시간(t1,t2,t3) 마다 변경하여 운전주파수와 보전주파수의 합으로 압축기를 운전한다.In addition, when the correction frequency set in the correction frequency setting step (S40) is set to the highest frequency, the correction frequency to a 에 corresponding to the minimum frequency, b 되는 corresponding to the intermediate frequency, c ㎐ corresponding to the highest frequency The compressor is operated at the sum of the operating frequency and the maintenance frequency by changing at predetermined times t1, t2 and t3, respectively.

상기에서 보정주파수를 변겨하는 소정시간(t1,t2,t3)은 주파수마다 동일하게 (t1 t2 t3) 또는 주파수가 높아질수록 긴 시간(t1t2t3)을 설정할 수도 있다.The predetermined times t1, t2, and t3 varying the correction frequency may be set equally for each frequency (t1 t2 t3) or longer time t1t2t3 as the frequency increases.

상기 압축기 운전 안정단계(S40)를 수행한 후, 압축기를 상기 운전주파수로 운전시킨다.After performing the compressor operation stabilization step (S40), the compressor is operated at the operating frequency.

이와 같이 본 발명은 실외온도가 낮아짐에 따라 증가하는 난방부하에 대응하기 위해 압축기 운전주파수를 보정하는 보정주파수를 높게 설정한 다음, 보정주파수를 낮은 보정주파수로부터 다단계로 증가시켜서 설정된 보정주파수에 이르도록 압축기를 운전하는 것으로, 실외온도가 낮은 상태의 초기 난방운전시 압축기에 가해지는 과부하는 방지하고, 냉매흐름을 안정화시킬 수 있어 경화상태인 배관에 흐르는 냉매의 진동으로 인한 소음 및 배관을 손상을 방지할 수 있다.As described above, the present invention sets the correction frequency for correcting the compressor operation frequency high to cope with the heating load that increases as the outdoor temperature decreases, and then increases the correction frequency in multiple steps from the low correction frequency to reach the set correction frequency. By operating the compressor, it prevents overload on the compressor during the initial heating operation at low outdoor temperature and stabilizes the refrigerant flow, thus preventing noise and damage to the pipe due to vibration of the refrigerant flowing into the hardened pipe. can do.

이상에서 살펴 본 바와 같이, 본 발명 인버터 공기조화기의 초기 난방운전시 압축기 제어방법은 초기 난방운전시 실외온도에 따라 압축기의 최고운전주파수를 설정하여 압축기에 과부하가 걸리는 것을 방지하고, 초기 난방운전시 실외온도에 따라 압축기의 보정주파수를 설정하여 압축기의 주파수를 다단계로 증가시켜서 압축기에 과부하가 걸리는 것을 방지하는 것으로, 초기 난방운전시 냉매흐름을 안정시켜서 냉매의 진동을 줄이므로 냉매의 진동에 의한 경화상태의 배관의 소음 및 배관의 손상을 방지할 수 있는 유용한 것이다.As described above, the compressor control method during the initial heating operation of the inverter air conditioner of the present invention sets the maximum operating frequency of the compressor according to the outdoor temperature during the initial heating operation to prevent the compressor from being overloaded, the initial heating operation By setting the correction frequency of the compressor according to the outdoor temperature at the time, it prevents the compressor from being overloaded by increasing the frequency of the compressor in multiple stages.
