Abstract
An air conditioner comprises a refrigeration cycle consisting of a compressor, a heat exchanger, a throttling device, a dryer provided with an adsorbent, a connection piping and a refrigerant. The refrigerant contains a hydrofluorocarbon refrigerant, the adsorbent contains a plurality of bulk particles, and the dryer includes a container, wherein the adsorbent is located within the container, having a pressing means for holding the adsorbent by pressing it. The load of the pressing means is within a range of about 0.5 kg/cm.sup.2 to about 3 kg/cm.sup.2. The container is of a cylindrical shape having a sectional area of 'A', the refrigerant is at a circulation rate of 'B', and the value of B/A is within a range of about 100 g/min cm.sup.2 to about 400 g/min cm.sup.2. The pressing means has a punching baffle formed with a plurality of through-holes, each one of the plurality of bulk particles has a mean diameter of 'D', each one of the plurality of through-holes has a diameter of 'C', and the value of D/C is at least about 2. The dryer removes water in the refrigeration cycle by allowing the adsorbent to adsorb water contained in the refrigerant.
