Abstract
In a heat storage system for a vehicle including a heat accumulator 3, in which engine coolant is stored and allowed to flow, in an engine coolant circulation circuit connecting an engine 1 and a heater core 2 of an air conditioning unit, the engine coolant circulation circuit is a circuit connecting heat accumulator 3 side inlet and outlet, engine 1 side inlet and outlet, and heater core 2 side inlet and outlet, and has a circuit configuration including four modes of a “heat storage mode,” a “heat storage maintaining mode,” a “quick engine warm-up mode,” and a “quick interior warm-up mode” to be selectable by switching a valve set in the circuit.
Claims8
A heat storage system for a vehicle comprising a heat accumulator, in which engine coolant is stored and allowed to flow, in an engine coolant circulation circuit connecting an engine and a heater core of an air conditioning unit, the system characterized in that
- the engine coolant circulation circuit is a circuit connecting heat-accumulator side inlet and outlet, engine side inlet and outlet, and heater-core side inlet and outlet, and has a circuit configuration in which four modes are selectable by switching a valve set in the circuit, the four modes including:
- a heat storage mode in which the engine coolant circulates at least through the engine side inlet and outlet and the heat-accumulator side inlet and outlet;
- a heat storage maintaining mode in which the heat-accumulator side inlet and outlet are disconnected;
- a quick engine warm-up mode in which hot water stored in the heat accumulator circulates only through the heat-accumulator side inlet and outlet and the engine side inlet and outlet;
- and a quick interior warm-up mode in which the hot water stored in the heat accumulator circulates only through the heat-accumulator side inlet and outlet and the heater-core side inlet and outlet.
