PURPOSE: A leakage sensor and a gas leakage sensing system for an air conditioner are provided to easily recognize gas leakage without dismantling the whole air conditioner. CONSTITUTION: A leakage sensor comprises a pneumatic motor, multiple intake pipes(121), and a discharge pipe. The intake pipes and the discharge pipe are connected to the pneumatic motor. A pressure guage is installed at the pipe to which the pneumatic motor is connected. Each of the multiple intake pipes comprises the pressure guage. A nozzle tip(210) is connected to the end part of the intake pipe. A guide block is connected to the nozzle tip and is located at a compressor(310). An auxiliary intake pipe(125) with a diameter different from that of the intake pipe is connected to the intake pipe. Air flow to the intake pipe from the discharge pipe is formed by the pressure generated when the pneumatic motor drives, and thus the compressor connected to the nozzle tip maintains a negative vacuum state.
