Problems solved by technology

If the ice in the evaporator increases, the heat exchange efficiency between the evaporator and the air will decrease, making it difficult to sufficiently cool the cold air supplied to the storage compartment
Therefore, there is a problem that the compressor needs to be driven more times and for a longer time
[0006] In addition, if frost forms on the evaporator, the heater is driven to remove ice from the evaporator. However, if the heater is driven unnecessarily frequently, there is a problem that the power consumed by the refrigerator increases.

Embodiment Construction

[0044] Hereinafter, preferred embodiments of the present invention that can specifically achieve the above objects will be described with reference to the accompanying drawings.

[0045] In this process, the size, shape, and the like of constituent elements shown in the drawings may be shown enlarged for clarity and convenience in description. Also, the terms specifically defined in consideration of the structure and action of the present invention may vary according to user's or operator's intention or custom. Such terms need to be defined based on the contents of the entire specification.

[0046] In an embodiment of the present invention, there is a technical difference between using one differential pressure sensor and using two pressure sensors. If two pressure sensors are used, the pressure difference at the two locations can be calculated using the pressure difference values ​​measured by the two pressure sensors respectively.

[0047] Usually, the pressure sensor mea...

Abstract

The present invention provides a refrigerator comprising: a cabinet having a storage chamber; a door for opening and closing the storage chamber; a case having a discharge port through which air is discharged to the storage chamber; an evaporator provided inside the case and for supplying cold air by means of heat exchange with air; a fan installed on the discharge port and for generating the airflow discharging to the storage chamber the air which has been heat exchanged in the evaporator; and a differential pressure sensor having a first pipe, of which one end is positioned on a part where the air is withdrawn to the fan, and a second pipe of which one end is positioned on a part where the air is discharged from the fan.

Description

technical field [0001] The present invention relates to a refrigerator and a control method thereof, and more specifically, to a refrigerator with improved energy efficiency and a control method thereof. Background technique [0002] Generally, a refrigerator is provided with a machine room at a lower portion of its body. Considering the center of gravity of the refrigerator, the efficiency of assembly, and vibration reduction, the machine room is usually arranged at the lower part of the refrigerator. [0003] For the mechanical room of this kind of refrigerator is equipped with a refrigeration cycle device, the property of absorbing external heat while the low-pressure liquid refrigerant is converted into gaseous refrigerant is used to keep the inside of the refrigerator in a frozen / refrigerated state, thereby freshly Preserve food. [0004] The refrigerating cycle device of the refrigerator includes: a compressor, which converts the low-temperature and low-pressure gase...
