Description

에어콘의 초기운전 제어방법{Start control method of air conditioner}Start control method of air conditioner

본 발명은 에어콘의 초기운전 제어방법에 관한 것으로서, 특히 에어콘의 작동 초기에 압축기의 진동 및 냉매의 압력 불균형을 해소하여, 소음 저감과 불필요한 전력소모를 줄일 수 있도록 한 에어콘의 초기운전 제어방법에 관한 것이다.The present invention relates to a method for controlling the initial operation of an air conditioner, and more particularly, to a method for controlling the initial operation of an air conditioner to reduce noise and reduce unnecessary power consumption by eliminating the vibration of the compressor and the pressure imbalance of the refrigerant at the initial stage of the operation of the air conditioner. will be.

잘 알려진 바와 같이 에어콘은 여름철 무더운 날씨에 사무실, 방 또는 건물내부와 같이 밀폐된 공간으로 냉풍을 공급하여 활동에 적합한 온도를 유지하는 것으로서, 공기조화(air conditioning)를 기본으로 한다.As is well known, the air conditioner supplies cool air to a confined space such as an office, a room or a building inside a hot summer season to maintain a temperature suitable for activity, and is based on air conditioning.

도 1은 에어콘의 일반적인 구성을 보여주고 있다.1 shows a general configuration of an air conditioner.

도시한 바와 같이 에어콘은 압축기(1), 응축기(2), 모세관(3) 및 증발기(4)로 구성되며, 이들을 배관을 통해 연결하고 그 내부로 냉매(통상 R-22)를 순환시키면서 냉풍을 만들어낸다.As shown, the air conditioner is composed of a compressor (1), a condenser (2), a capillary tube (3) and an evaporator (4), connecting them through a pipe and circulating a refrigerant (usually R-22) inside the cold air Create

가스 상태의 냉매는 먼저 압축기(1)에 의해 고온 고압으로 압축되어 응축기(2)에서 액화되고, 모세관(3)을 통해 압력이 강화되어 증발기(4)로 보내지며, 여기서 주위의 열을 뺏어 증발하고 가스 상태로 되어 다시 압축기(1)로 보내지며 반복 순환되어진다.The gaseous refrigerant is first compressed to high temperature and high pressure by the compressor (1) and liquefied in the condenser (2), the pressure is increased through the capillary tube (3) and sent to the evaporator (4), where the ambient heat is taken away and evaporated The gas is returned to the compressor 1 and circulated repeatedly.

이때 차가워진 증발기(4)로 사무실, 방 및 건물 내부의 더운 공기를 송풍하여 통과시킴으로써 냉풍을 만들고, 이것을 실내로 공급하여 공기조화를 수행한다.At this time, by cooling the evaporator (4) by passing the hot air in the office, room, and inside the building to create a cold air, it is supplied to the room to perform the air conditioning.

이와 같이 작동하는 에어콘에서 압축기(1)는 해당 지역의 적용 전원 주파수에 비례하여 일정한 회전수를 갖도록 설정된다. 그러나 에어콘의 운전 초기에 압축기(1)로 공급되는 전원은 초기제어 없이 바로 인가되므로, 압축기(1)의 부하를 증가시켜 불필요한 전력소모를 초래하며, 냉매의 급격한 유량 변화로 진동 및 소음을 발생시키는 문제점이 있다.In the air conditioner operating in this way, the compressor 1 is set to have a constant rotational speed in proportion to the applied power frequency of the region. However, since the power supplied to the compressor 1 at the initial stage of the operation of the air conditioner is directly applied without initial control, the power of the compressor 1 is increased to cause unnecessary power consumption, and vibration and noise are generated by a sudden change in the flow rate of the refrigerant. There is a problem.

앞서 설명한 종래 기술의 문제점을 해소하기 위한 것으로서, 본 발명은 운전 초기에 압축기로 공급되는 전압을 제어하여 부하증가를 낮춤으로써, 진동 및 소음을 저감시키고 불필요한 전력소모를 방지할 수 있도록 하는 에어콘의 초기운전 제어방법을 제공하는데 그 목적이 있다.In order to solve the problems of the prior art described above, the present invention is to control the voltage supplied to the compressor at the beginning of operation to reduce the increase in load, thereby reducing the vibration and noise and to prevent unnecessary power consumption of the initial air conditioner The purpose is to provide a method for controlling operation.

상기 목적을 달성하기 위하여 본 발명은 에어콘의 운전 초기에 전원 스위치의 온에 의해 압축기로 공급되는 상용 전원을 전압 제어부를 통해 구동 최소전압까지 강압시켜 인가하는 단계와, 이후 상기 최소전압을 단계적이고 일정 시간간격으로 승압시키는 단계를 포함한다.In order to achieve the above object, the present invention provides a step of applying the commercial power supplied to the compressor by turning on the power switch at the initial stage of the air conditioner to a minimum driving voltage through a voltage control unit, and then applying the minimum voltage step by step. Boosting at a time interval.

이하, 첨부 도면에 의거하여 본 발명의 바람직한 실시예를 설명한다. 참고로 본 발명을 설명함에 있어 종래 기술의 구성과 동일한 부분에 대하여는 동일 부호를 부여하기로 한다.EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described based on an accompanying drawing. For reference, in describing the present invention, the same reference numerals will be given to the same parts as the configurations of the prior art.

도 2는 본 발명에 의한 초기운전 제어방법를 설명하는 블럭도이다.2 is a block diagram illustrating a method for controlling initial operation according to the present invention.

도면에서와 같이 본 발명은 에어콘의 운전 초기에 압축기(1)로 인가되는 상용 전원(단상 60㎐인 경우 220V)에 의한 부하를 경감시키기 위해, 운전 초기 전압을 시스템에서 요구하는 최소 구동전압까지 하강시켜 일정시간 운전하고, 냉매 사이클의 유량 변화가 순조로울 때 다시 상용 전원으로 복원시키는 방법을 채용한다.As shown in the drawing, the present invention lowers the initial operating voltage to the minimum drive voltage required by the system in order to reduce the load by the commercial power source (220V in the case of 60 Hz) applied to the compressor 1 at the initial stage of the air conditioner operation. Operation for a certain period of time, and when the flow rate change of the refrigerant cycle is smooth, the method is restored to the commercial power source.

이를 위하여 본 발명에서는 에어콘의 실외기 유닛(5)의 압축기 구동부(6)와 압축기(1)의 사이에 전압 제어부(7)를 설치한다.To this end, in the present invention, the voltage control unit 7 is provided between the compressor driving unit 6 and the compressor 1 of the outdoor unit 5 of the air conditioner.

전압 제어부(7)는 실내 유닛(9)의 실내 제어부를 통하여 실외 제어부(8)로공급되고 다시 압축기 구동부(6)로 공급된 상용 전원을 냉매 사이클이 구성될 수 있는 구동 최소전압까지 강압시켜 압축기(1)로 인가한다. 구동 최소전압은 상용 전원의 -10%이며, 단상 60㎐ 220V의 상용 전원의 경우 200V까지 하강시킨다.The voltage controller 7 lowers the commercial power supplied to the outdoor controller 8 through the indoor control unit of the indoor unit 9 and back to the compressor driver 6 to a driving minimum voltage at which a refrigerant cycle can be configured. (1). The minimum driving voltage is -10% of the commercial power supply, and in the case of a commercial power supply with a single phase of 60㎐ 220V, the voltage drops to 200V.

이에 따라 압축기(1)는 회전수가 낮아져 서서히 작동하게 되며 초기 부하 및 냉매 사이클의 유량 변화를 최소화할 수 있다. 이후 시스템이 지속적으로 가동되고 냉매 사이클의 유량 변화가 순조로워지면, 전압 제어부(7)에서는 단계적이고 일정 시간간격으로 전압을 증가시켜 상용 전원인 220V까지 승압시킨다.Accordingly, the compressor 1 may operate slowly due to the low rotational speed and minimize the change in flow rate of the initial load and the refrigerant cycle. Then, when the system is continuously operated and the flow rate change of the refrigerant cycle is smooth, the voltage control unit 7 increases the voltage step by step and a predetermined time interval to boost up to 220V, which is a commercial power supply.

이때 전압 제어부(7)는 적어도 5단계를 거쳐 전압과 승압 시간간격을 설정하는 것이 좋지만, 그 수치는 에어콘의 사용용도 및 종류에 따라 다양하게 설정할 수 있다. 예를 들어 전압 제어부(7)는 최초 인가되는 상용 전원을 200V로 하강시키고, 이후 일정 시간간격으로 4V씩 서서히 승압시켜 압축기(1)로 인가되는 전원을 다시 220V의 상용 전원까지 복원시킨다.In this case, the voltage controller 7 may set the voltage and the boosting time interval through at least five steps. However, the voltage controller 7 may be variously set according to the use and type of the air conditioner. For example, the voltage control unit 7 lowers the commercial power applied first to 200V, and then gradually boosts the power by 4V at a predetermined time interval to restore the power applied to the compressor 1 to the commercial power of 220V again.

이러한 작용에 따라 본 발명의 압축기(1)는 에어콘의 운전 초기에 부하가 경감되어 원활한 작동을 실현할 수 있다.According to this action, the compressor 1 of the present invention can realize a smooth operation by reducing the load at the beginning of the operation of the air conditioner.

이상에서 설명한 실시예를 통하여 알 수 있는 바와 같이, 본 발명은 운전 초기에 압축기로 공급되는 전압을 제어하여 구동 최소전압으로 낮춤으로써, 압축기의 부하를 경감시킬 수 있으며, 냉매 사이클의 급격한 유량 변화를 방지할 수 있다.As can be seen through the embodiments described above, the present invention can reduce the load of the compressor by controlling the voltage supplied to the compressor at the beginning of operation to lower the driving minimum voltage, and the rapid change in flow rate of the refrigerant cycle You can prevent it.

따라서 본 발명에 의하면 압축기의 진동 및 실외기 파이프의 진동 및 소음을감소시킬 수 있으며, 불필요한 전력소모를 방지할 수 있다.Therefore, according to the present invention, the vibration of the compressor and the vibration and noise of the outdoor unit pipe can be reduced, and unnecessary power consumption can be prevented.
