Abstract
A refrigeration apparatus pertaining to the invention can suppress clogging due to polymers formed by the polymerization of refrigerant and improve safety. The refrigeration apparatus is equipped with a refrigeration cycle in which a compressor, a condenser, an expansion mechanism, and an evaporator are connected in a loop. The refrigeration apparatus is equipped with a polymer catcher. The polymer catcher is attached to piping interconnecting an outlet side of the compressor and an inlet side of the condenser and catches polymers of refrigerant circulating in the refrigeration cycle. The refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds.
