Abstract
A manufacturing method for an air conditioner including the steps of: (a) assembling a refrigeration cycle by connecting an outdoor unit, which has a compressor containing a refrigerant and an outdoor heat exchanger to a dummy indoor unit, and a part including a moisture adsorbent, using connection piping; (b) operating the refrigeration cycle by either an intermittent heating operation or switching between cooling and heating operations to adsorb moisture contained in the refrigeration cycle using a moisture adsorbent; (c) disconnecting the part including the moisture adsorbent after adsorbing moisture from the refrigeration cycle, and (d) measuring the water content contained in the moisture adsorbent, to control the water contained in the outdoor unit.
