Embodiment Construction

[0037] figure 1 It is a diagram showing the configuration of a thermal cycle of an air conditioner according to an embodiment of the present invention.

[0038] according to figure 1 According to the embodiment of the present invention, the air conditioner 1 includes: a compressor 10 for compressing refrigerant; an indoor heat exchanger 21 that flows into the refrigerant compressed by the compressor 10 into a high-temperature and high-pressure refrigerant to exchange heat with indoor air ; Send the hot air through the heat exchange to the indoor fan 22 indoors; expand the refrigerant through the heat exchange into a low-pressure expansion device, that is, the capillary 30; and the outdoor unit fan 42 that sends the cold air after the heat exchange to the outside.

[0039] Specifically, when the heating cycle is performed by the air conditioner, the indoor heat exchanger 21 uses a condenser for condensing the refrigerant compressed by the compressor 10 to a low temperature, a...

Abstract

An air conditioner is provided. A compressor compresses refrigerant. An indoor heat exchanger performs heat exchange between the refrigerant and indoor air. An expansion device decompresses the refrigerant. An outdoor heat exchanger performs heat exchange between the refrigerant and outdoor air. Sensors sense temperature of the outdoor heat exchanger, indoor temperature and outdoor temperature. Aheater generates heat variably according to the outdoor temperature and the outdoor heat exchanger temperature. A controller determines quantity of frost on the outdoor heat exchanger by comparing a preset reference temperature with a temperature difference between the outdoor heat exchanger and the outdoor heat exchanger temperature, and controls output of the heater according to the determined frost quantity. Accordingly, frost quantity is determined according to the indoor and outdoor temperatures and the outdoor heat exchanger temperature, and heat quantity of the induction heater is accordingly varied. Therefore, power consumption can be reduced.

Description

technical field [0001] The invention relates to an air conditioner and a control method thereof. Background technique [0002] In general, an air conditioner is a home appliance that keeps indoor air in an optimal state according to its use and purpose. For example, the room is adjusted to a cool cooling state in summer, and the room is adjusted to a warm heating state in winter, and the indoor humidity is adjusted to keep the indoor air in a comfortable state. [0003] With the gradual expansion of the use of daily convenience products such as air conditioners as described above, consumer demand for products with high energy efficiency, high performance and ease of use is increasing. [0004] The above-mentioned air conditioners can be classified into: a separate type air conditioner that is separated into an indoor unit and an outdoor unit; and an integrated type air conditioner that combines the indoor unit and the outdoor unit into one device. Moreover, according to th...
