Definitions

  • Still another object of the invention is to early detect a leakage of refrigerant after the normal operation is started and to determine the quantity of refrigerant with a high degree of precision.
  • Information on a determination as to the refrigerant may be displayed on a terminal of a service center through an internet.
  • the above-described refrigerant quantity determining operation mode may be configured so as to be forcedly carried out automatically while the cooling operation of all indoor units which are connected to the air conditioner is carried out, and accordingly, by carrying out the refrigerant quantity determination, it is possible to further improve the precision of the refrigerant quantity.
  • the refrigerant quantity determining operation mode may not be automatically carried out, but the service man may operate a switch etc. installed in the outdoor unit, or the refrigerant quantity determining operation mode may be carried out using a personal computer by connecting the personal computer to the air conditioner.
  • the refrigerant quantity determining operation may be carried out by connecting the air conditioner to a network computer or a central controller in order to change over the operation thereof into the refrigerant quantity determining operation mode.
