An air conditioner comprises an outdoor unit including a compressor and an outdoor heat exchanger; and an indoor unit connected to the outdoor unit by a gas pipe and a liquid pipe and having an indoor heat exchanger including a first coil and a second coil branched from the gas pipe and connected in parallel, a first manifold and a second manifold connected by refrigerant pipes to enable refrigerant to flow to the indoor heat exchanger, a first expansion valve and a second expansion valve connected in parallel to the liquid pipe and that block or expand the refrigerant, refrigerant flow pipes connecting a gas pipe side of the first manifold and an outlet side of the second expansion valve, a third expansion valve installed on the refrigerant flow pipe to block or expand the refrigerant, and a control valve installed on the gas pipe to block the refrigerant.

Air conditioner and method for controlling same

A fuel cell apparatus may include a stack, a stack air blower configured to supply external air to the stack, a humidifier configured to extract moisture contained in exhaust air and to supply the extracted moisture to external air supplied to the stack, a first bypass channel configured to allow exhaust air to bypass the humidifier, a first three-way valve controlled to adjust the amount of exhaust air that bypasses the humidifier, and a humidity sensor configured to sense the humidity of external air. The fuel cell apparatus may also include a second bypass channel configured to allow external air to bypass the humidifier, a second three-way valve controlled to adjust the amount of external air that bypasses the humidifier, and a controller configured to control the first three-way valve and the second three-way valve depending on the sensed humidity value of the external air.

Fuel cell apparatus

A robot for moving in an administrator mode, can include a positioning sensor configured to sense a transmitter for calculating a position of the transmitter; an obstacle sensor configured to sense an obstacle around the robot; a driver configured to move the robot; and a controller configured to in response to receiving a signal from the transmitter, align the robot toward the position of a transmitter, move the robot toward the transmitter while avoiding one or more obstacles sensed by the obstacle sensor, and in response to no longer receiving the signal from the transmitter or a distance between the transmitter and the robot being equal to or less than a preset distance, stop the robot.

Method of moving robot in administrator mode and robot of implementing method

Provided are a marker for space recognition, a method of moving and lining up a robot based on space recognition, and a robot, and the robot that lines up and moves based on space recognition includes: a camera sensor that images a marker disposed on a traveling floor of the robot or a side of the traveling floor; and a control unit that analyzes an image captured by the camera sensor, calculates a moving direction or a moving speed of the robot on the basis of the marker, and controls a movement unit.

Marker for space recognition, method of moving and lining up robot based on space recognition and robot of implementing thereof

A robot can include a cart to receive one or more objects; a camera sensor to photograph a periphery of the robot and capture an image of a user of the robot; a handle assembly coupled to the cart; a moving part to move the robot; a force sensor to sense a force applied to the handle assembly; and a controller configured to generate physical characteristics information on physical characteristics of the user of the robot based on the image of the user, and adjust at least one of a moving direction of the robot, a moving speed of the moving part and a value of torque applied to a motor of the moving part, based on the physical characteristics information and a magnitude of the force applied to the handle assembly sensed by the force sensor.

Method of moving in power assist mode reflecting physical characteristics of user and robot implementing thereof

An antitheft system of a user terminal module and a mobile robot capable of being used as a shopping cart are disclosed. The antitheft system includes: a user terminal module generating terminal location data comprising location coordinates; a mobile robot assisting in driving through conversion of a drive mode into a preset drive mode depending upon a location of the user terminal module and a distance from the mobile robot to the user terminal module while generating and outputting robot location data comprising location data thereof in real time; and a monitoring device monitoring locations of the user terminal module and the mobile robot in real time and controlling the terminal module and the mobile robot to perform an antitheft operation depending upon a region in which the terminal module and the mobile robot are placed, thereby improving reliability by preventing theft and loss of the user terminal module and the mobile robot.

Antitheft system of mobile robot

An accumulator and an air conditioner having the same are provided. The air conditioner may include at least one indoor unit connected to an outdoor unit, the outdoor unit including a compressor compressing refrigerant and an accumulator transferring gas refrigerant into the compressor. The accumulator may include a housing, an inflow tube guiding refrigerant into the housing through a guide tube, and a discharge tube discharging the refrigerant from the housing. A portion of the guide tube protrudes out of the housing, and a distance between the discharge tube and a bottom of the housing is greater than that between the protruded portion of the guide tube and the bottom of the housing.
