Temperature control system

A temperature control system for a vehicle, the temperature control system comprising:

• a refrigeration cycle circuit configured to allow a refrigerant to circulate therethrough;
• and
• a cooling water circuit configured to allow cooling water to circulate therethrough, wherein the refrigeration cycle circuit includes a compressor configured to compress the refrigerant, a radiator configured to heat air used for air conditioning using heat of the refrigerant compressed by the compressor, and a first heat exchanger configured to exchange heat between the refrigerant and the cooling water in the cooling water circuit, and
• the cooling water circuit includes:
• a first cooling water circuit including the first heat exchanger, a storage battery heat exchanger configured to exchange heat with a storage battery, and a first pump configured to suction and discharge the cooling water, and configured to allow the cooling water to circulate therethrough;
• a second cooling water circuit including an external heat exchanger configured to exchange heat between the cooling water and outside air, a drive system heat exchanger configured to exchange heat with a drive system component that drives the vehicle, and a second pump configured to suction and discharge the cooling water, and configured to allow the cooling water to circulate therethrough;
• a first thermal coupler configured to switch the cooling water circulating through the first cooling water circuit and the cooling water circulating through the second cooling water circuit between thermal coupling and separation;
• and
• a bypass circuit including an on-off valve capable of blocking a flow of the cooling water, connected to upstream and downstream of the external heat exchanger, and provided in parallel with the first cooling water circuit.
