Vehicle temperature control apparatus and in-vehicle thermal system

A vehicle temperature control apparatus for controlling temperature of a temperature control object which is at least one of inside air of a vehicle compartment and a vehicle component, the vehicle temperature control apparatus comprising:

• a heat capacitive element capable of storing heat;
• a refrigeration cycle in which heat is absorbed from a low temperature side and is dissipated to a high temperature side;
• a heat exchanger that causes the heat stored in the heat capacitive element to be exchanged with a refrigerant of the refrigeration cycle;
• a first heat dissipation portion configured to dissipate heat contained in the refrigerant of the refrigeration cycle to the temperature control object;
• an interrupter that interrupts and resumes a heat storage in the heat capacitive element and heat dissipation from the heat dissipation portion to the temperature control object;
• a controller that controls the interrupter based on a determination result of heat storage requirement whether the heat capacitive element is required to store heat therein;
• and
• a heat collection portion that collects heat remaining in the vehicle to the heat capacitive element, wherein
• the controller controls the interrupter so that heat is firstly stored in the heat capacitive element and is then dissipated from the heat capacitive element to the temperature control object, when the controller determines that the heat capacitive element is required to store heat,
• the controller calculates a target temperature of the heat capacitive element and controls the interrupter based on the target temperature,
• the controller changes the target temperature to be different from each other between a case in which it is determined that the heat storage in the heat capacitive element is required, and a case in which it is determined that the heat storage in the heat capacitive element is not required;
• the interrupter is configured to interrupt and resume heat collection by the heat collection portion, and
• the controller controls the interrupter such that heat collection by the heat collection portion is started when an ignition switch of the vehicle is turned off.
