Description

냉장고 및 그 구동제어방법Refrigerator and its driving control method

본 발명은, 냉동실 및 냉장실이 구비된 냉장고 및 그 구동제어방법에 관한 것으로서, 보다 상세하게는 상기 냉동실 및 상기 냉장실의 냉각조건에 따라 압축기의 구동속도를 제어하여 에너지소비효율을 향상시킬 수 있으며, 또한, 압축기의 내용수명이 연장되도록 한 냉장고 및 그 구동제어방법에 관한 것이다.The present invention relates to a refrigerator having a freezer compartment and a refrigerating compartment and a driving control method thereof, and more particularly, to control the driving speed of a compressor according to cooling conditions of the freezer compartment and the refrigerating compartment, thereby improving energy consumption efficiency. The present invention also relates to a refrigerator and a drive control method thereof for extending the service life of the compressor.

냉장고는 일반적으로 비교적 저온의 냉동실과 상대적으로 고온의 냉장실을 가지며, 이들 냉동실과 냉장실내에 수용된 음식물을 냉각하기 위한 냉동시스템을 구비한다.Refrigerators generally have a relatively low temperature freezer compartment and a relatively high temperature refrigerating compartment, and include a refrigerating system for cooling the food contained in the freezer compartment and the refrigerating compartment.

일반적인 냉동시스템은, 냉매를 압축하는 압축기와, 압축기로부터 압축된 고온고압상태의 냉매를 방열을 통하여 응축하는 응축기와, 응축기로부터의 냉매를 제공받아 냉매가 증발하면서 주위의 잠열을 흡수하는 냉각작용에 의하여 주변의 공기를 냉각하는 증발기를 가진다. 또한, 냉동실 및 냉장실에는 각각 냉동실팬 및 냉장실팬이 부속되어 있으며, 이들 냉동실팬 및 냉장실팬은 증발기를 통과하면서 열교환되어 냉각된 공기를 해당 냉각실을 향하여 송풍하게 된다. 냉동실 및 냉장실에는 각각의 실내온도를 검출할 수 있도록 냉동실온도센서 및 냉장실온도센서가 각각 구비된다.A general refrigeration system includes a compressor that compresses a refrigerant, a condenser that condenses the refrigerant at a high temperature and high pressure state compressed by the compressor, and a cooling operation that absorbs latent heat while the refrigerant is evaporated by the refrigerant from the condenser. It has an evaporator which cools surrounding air. In addition, a freezer compartment and a refrigerating compartment fan are respectively attached to the freezer compartment and the refrigerating compartment, and these freezer compartment fans and the refrigerating compartment fans are blown through the evaporator to heat the cooled air toward the corresponding cooling compartment. The freezing compartment and the refrigerating compartment are provided with a freezing compartment temperature sensor and a refrigerating compartment temperature sensor, respectively, to detect respective indoor temperatures.

이러한 냉동시스템이 구비된 냉장고는 제어프로그램이 내장된 마이컴등에 의하여 설정된 냉동조건 및/또는 냉장조건에 따라 압축기, 냉동실팬 및 냉장실팬을 제어하여 냉동조건 및/또는 냉장조건을 달성하게 된다.The refrigerator equipped with such a refrigeration system controls the compressor, the freezer compartment and the refrigerating compartment fan according to a freezing condition and / or a refrigeration condition set by a microcomputer with a built-in control program to achieve a freezing condition and / or a refrigeration condition.

그런데, 이러한 종래의 냉장고에 있어서는, 냉동실팬과 냉장실팬이 동시에 구동되는 비교적 많은 냉매압축량이 소요되는 경우와, 냉동실팬과 냉장실팬중 어느 하나만 작동되는 경우와 같이, 상대적으로 적은 냉매압축량을 필요로 하는 경우에있어서도 압축기가 동일한 속도로 구동되게 된다. 따라서, 냉동실온도센서 및 냉장실온도센서로부터 검출신호에 기초하여 냉동실팬 및 냉장실팬중 어느 하나가 작동하더라도 압축기가 작동하게 됨으로써, 압축기의 기동회수가 증가하게 된다. 이에 따라, 압축기의 강제열화에 의한 내용수명이 단축되고, 고장의 원인이 될 수 있으며, 또한, 사용소비전력이 증대되는 문제점이 있다.However, in such a conventional refrigerator, a relatively small amount of refrigerant compression is required, such as a case where a relatively large amount of refrigerant compression in which the freezer compartment fan and the refrigerating compartment fan are driven simultaneously and only one of the freezer compartment fan and the refrigerating compartment fan are operated. In this case, the compressor is driven at the same speed. Therefore, even if any of the freezer compartment fan and the refrigerating compartment fan operates based on the detection signal from the freezer compartment temperature sensor and the refrigerating compartment temperature sensor, the compressor is operated, thereby increasing the starting frequency of the compressor. As a result, the service life of the compressor is forcibly reduced, which may cause a failure, and also increase the power consumption.

따라서, 본 발명의 목적은, 냉각조건에 따라 압축기의 구동속도를 제어하여 압축기가 빈번하게 기동되는 것을 방지할 수 있으며, 이에 따라 압축기의 내용수명이 연장되고 사용소비전력이 절감되는 냉장고 및 그 구동제어방법을 제공하는 것이다.Accordingly, an object of the present invention is to control the driving speed of the compressor according to the cooling conditions to prevent the compressor from being frequently started, thereby extending the useful life of the compressor and reducing the power consumption of the compressor and its driving. It is to provide a control method.
