Document Type and Number:
WIPO Patent Application WO/2019/208634
Kind Code:
A1
Abstract:
[Problem] To provide a hot/cold storage container capable of precise temperature management in which temperature changes are suppressed.
[Solution] A hot/cold storage container (1) has an outer box (10) in the interior of which a chamber for storing an object is formed, and a first refrigeration circuit (21) for cooling the interior of the chamber. The first refrigeration circuit (31) is provided with, in a refrigerant circulation passage (33), at least an internal evaporator (21) that exchanges heat with the interior of the chamber, thereby evaporating a refrigerant, a compressor (35) for compressing the refrigerant, and an external evaporator (38) that is arranged in the circulation passage (33) on the upstream side of the compressor (35), and that exchanges heat with the outside of the chamber. The refrigerant flowing from the internal evaporator (21) passes through the external evaporator (38) and then returns to the compressor (35).
