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.

Claims (15)

1 . A refrigeration apparatus 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 comprising:

a polymer catcher that 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,

wherein the refrigerant includes a compound represented by a molecular formula having one or more carbon-carbon unsaturated bonds.

2 . The refrigeration apparatus according to claim 1 , further comprising a four-way switching valve that is attached to the piping, wherein the polymer catcher is attached between the outlet side of the compressor and an inlet side of the four-way switching valve.

3 . The refrigeration apparatus according to claim 1 , wherein the polymer catcher is a filter that suppresses passage of the polymers.

4 . The refrigeration apparatus according to claim 1 , wherein the polymer catcher is a dryer that has an adsorbent that adsorbs the polymers.

5 . The refrigeration apparatus according to claim 4 , wherein the dryer further has a stabilizer and an antioxidant.

6 . The refrigeration apparatus according to claim 1 , wherein the condenser has multi-hole flat tubes through which the refrigerant flows.

7 . The refrigeration apparatus according to claim 2 , wherein the polymer catcher is a filter that suppresses passage of the polymers.

8 . The refrigeration apparatus according to claim 2 , wherein the polymer catcher is a dryer that has an adsorbent that adsorbs the polymers.

9 . The refrigeration apparatus according to claim 3 , wherein the polymer catcher is a dryer that has an adsorbent that adsorbs the polymers.

10 . The refrigeration apparatus according to claim 2 , wherein the condenser has multi-hole flat tubes through which the refrigerant flows.

11 . The refrigeration apparatus according to claim 3 , wherein the condenser has multi-hole flat tubes through which the refrigerant flows.

12 . The refrigeration apparatus according to claim 4 , wherein the condenser has multi-hole flat tubes through which the refrigerant flows.

13 . The refrigeration apparatus according to claim 5 , wherein the condenser has multi-hole flat tubes through which the refrigerant flows.
