First claim

The invention claimed is:

1. A freezer comprising a haloolefin-based composition, the haloolefin-based composition comprising:
(a) HFO-1234yf;
(b) HFO-1234ze in an amount of 0.1 ppm by weight or more and 10,000 ppm by weight or less based on the total amount of the (a) HFO-1234yf;
(c) water in an amount of 3 ppm by weight or more and 200 ppm by weight or less based on the total amount of the (a) HFO-1234yf; and
(d) oxygen in an amount of more than 0 mol % and 0.35 mol % or less based on the total amount of the (a) HFO-1234yf.

2. The freezer according to claim 1 , wherein the haloolefin-based composition further comprises (e) at least one component selected from the group consisting of polyalkyleneglycol and polyolester.

3. A freezer comprising a haloolefin-based composition, the haloolefin-based composition comprising:
(a) HFO-1234ze;
(b) HFO-1234yf in an amount of 0.1 ppm by weight or more and 10,000 ppm by weight or less based on the total amount of the (a) HFO-1234ze;
(c) water in an amount of 3 ppm by weight or more and 200 ppm by weight or less based on the total amount of the (a) HFO-1234ze; and
(d) oxygen in an amount of more than 0 mol % and 0.35 mol % or less based on the total amount of the (a) HFO-1234ze.

4. The freezer according to claim 3 , wherein the haloolefin-based composition further comprises (e) at least one component selected from the group consisting of polyalkyleneglycol and polyolester.
