Method for control operating delay of air conditioner

The present invention relates to a multi-type air conditioner for cooling and heating combined which a plurality of indoor units connected to one outdoor unit, operating the start-up delay conditions of the compressor mode, outdoor temperature, operation latency, activation for compressor protection by limiting the system temperature etc. to provide a driving delay control method that can optimize the delay time has its purpose. The present invention for this purpose is characterized in that in operation the delay control of the air conditioning method for a compressor protection, the operation mode of an air conditioner in a heating operation is determined, and the determination is the heating operation is less than the outdoor temperature of the predetermined set to sense the temperature , the outdoor temperature is a set temperature or less when the outdoor power-up after If the operation waiting time determined entity has elapsed for a predetermined time, and the operation standby time period has not elapsed the predetermined time compressor discharge temperature and the outdoor heat exchanger pipe temperature difference and calculating the predetermined reference temperature, or less is determined, and a, and performs a start-up delay control of the compressor to the compressor discharge temperature and the outdoor heat exchanger pipe temperature is below the reference temperature to delay the compressor start-up and operation of the heater to heat the compressor.
