<p>PROBLEM TO BE SOLVED: To provide an air conditioner that can make correction to reach an optimal target discharge temperature even when specifications of a plurality of types of indoor units to be connected vary in single connection for connecting an outdoor unit with the indoor unit on a one-to-one basis.SOLUTION: An air conditioner includes: an indoor heat exchanger 15 functioning as a condenser or an evaporator; an outdoor heat exchanger 13; a four-way valve 12; a compressor 11; an electronic expansion valve 14; and an outdoor unit control section 16 for controlling an opening of the electronic expansion valve. The outdoor unit control section 16 includes: storage means 26 for storing an evaporation temperature Te, a condensation temperature Tc and a superheat degree SH; theoretical cycle discharge temperature Trd calculation means 28 for making a calculation from the Te, Tc, SH; target discharge temperature Tmd calculation means 29 for adding a correction value Thd of an error cause to the Trd; and final target discharge temperature Tmd2 calculation means 34 for adding a correction value Tht depending on a form of an indoor unit to the Tmd. The opening of the electronic expansion valve 14 is adjusted so that a discharge temperature Td of the compressor 11 comes close to the Tmd2.</p> |
