1. A heat transport device comprising:
a circulation route enclosing a refrigerant containing at least one of hydrofluoroolefins (HFOs), hydrochlorofluoroolefins (HCFOs), or hydrochloroolefins (HCOs),
wherein the circulation route includes:
a condenser;
an expansion mechanism;
an evaporator;
a compressor; and
a stabilizer container containing an acid scavenger, the stabilizer container being located in the circulation route between the expansion mechanism and the evaporator in a refrigerant circulation direction, and the refrigerant enclosed in the circulation route and flowing through the stabilizer container consists essentially of refrigerant in a gas-liquid mixed state, the refrigerant enclosed in the circulation route and flowing from the expansion mechanism to the compressor being at a lower pressure than the refrigerant enclosed in the circulation route and flowing from the compressor to the expansion mechanism;
wherein the acid scavenger is at least one member selected from a group consisting of polyhydric alcohols, amines, alkyl epoxides, and alkenyl tolyls, and
wherein the heat transport device is a cooling water chiller.
