[0031] figure 2 is a schematic block diagram of an operation control device of an air conditioner adapted to apply the method for controlling stop operation of the air conditioner according to one embodiment of the present invention. The operation control device of the air conditioner includes an operation block 202, a first pressure sensor 204, a second pressure sensor 206, a control block 208, a compressor driving block 210, an EEV driving block 212, an indoor fan driving block 214, an outdoor fan driving block 216 and Four-way valve drive block 218.

[0032] refer to figure 2 , the operation block 202 is provided with a plurality of operation keys that allow the user to select the operation information of the air conditioner, such as power on, operation mode (cooling operation mode, heating operation mode, etc.), specified temperature, air volume, etc. Various kinds of operation information generated by user input are forwarded to the control block 208 .

Abstract

A method for controlling a stop operation of an air conditioner having a compressor, a four-way valve, an electronic expansion valve (EEV), an indoor fan and an outdoor fan, includes the steps of stopping the operations of the compressor and the indoor fan if an operation stop signal is inputted during a heating operation; and checking an amount of elapsed time after the turn-offs of the compressor and the indoor fan, and turning off the EEV and the outdoor fan if the amount of elapsed time reaches a preset reference time. The methods also includes the steps of detecting pressures at an inlet side and at an outlet side of the compressor to calculate a pressure difference; and turning off the four-way valve if the calculated pressure difference reaches a preset reference pressure difference.

Description

technical field [0001] The present invention relates to an operation control method of an air conditioner, and more particularly, to a stop operation control method of an air conditioner adapted to control the stop operation based on the internal environment (pressure and temperature) of the air conditioner when the air conditioner is stopped in a heating operation mode. Background technique [0002] As is well known in the art, as an example, a typical air conditioner has figure 1 structure shown. [0003] refer to figure 1 , a typical air conditioner is roughly divided into an outdoor unit 110 and an indoor unit 120 . The outdoor unit 110 is composed of a compressor 111, a four-way valve 112, an outdoor heat exchanger 113, an electronic expansion valve (EEV) 114, an accumulator 115, an outdoor fan 116, and any other components apparent to those skilled in the art. other items. The indoor unit 120 is composed of an indoor heat exchanger 121, an indoor fan 123, and the l...
