Abstract

A device and a method for controlling a drain pump of a multi type air conditioner are provided to carry out draining of condensed water continuously even when an operation capacity of the drain pump is decreased. A device for controlling a drain pump of a multi type air conditioner comprises a float switch(2) for generating a float sensing signal as condensed water is filled, a drain pump(8) for discharging the condensed water to the outside, and a control part(16) for determining deterioration of an operation capacity of the drain pump and controlling the drain pump to operate through first and second steps. The drain pump is driven for a set first time period in the first step for restraining generation of condensed water, and for a set second time period in the second step for stopping operation of an indoor unit, wherein the second time period is longer than the first one.

Description

technical field [0001] The present invention relates to a drain pump control device and method for a multi-connected air conditioner, in particular to cutting off the flow of refrigerant and making the drain pump work for a predetermined time when a float detection signal continues to occur within a certain period of time, and then if the float detection signal still occurs The signal stops the operation of the indoor unit and additionally operates the drainage pump for a period longer than a predetermined time. The drainage pump control device and method of the multi-connected air conditioner. Background technique [0002] Usually, a multi-connected air conditioner consists of multiple indoor units and outdoor units and is installed in a large building such as a building. The multiple outdoor units are installed outside the building, and the multiple indoor units are installed on the ceiling or wall inside the building. and so on. [0003] In addition, each of the pluralit...
