Abstract: A vehicle-mounted temperature controller has a first heat circuit and a refrigeration circuit. The first heat circuit has a first radiator exchanging heat with outside air, a first heat exchanger, and a first pump, and configured so that a first heat medium is circulated therethrough. The refrigeration circuit has the first heat exchanger discharging heat from the refrigerant to a first heat medium to make a refrigerant condense, a second heat exchanger absorbing heat to the refrigerant to thereby make the refrigerant evaporate and to cool an object to be cooled, and a compressor, and is configured so that the refrigerant circulates through the first heat exchanger and the second heat exchanger and thereby a refrigeration cycle is realized. When the object to be cooled starts being cooled, the compressor is started up after the first pump is started up.

Abstract: A control apparatus of a heat exchanging system according to the invention activates a connection system to connect an engine water passage to a heater water passage and then, shuts off a heater water passage portion between a portion, into which heat exchanging water flows from the engine water passage and a portion, from which the heat exchanging water flows out toward the engine water passage, and decreases heater pump and engine pump duty ratios when the duty ratios should be decreased for controlling core and engine flow rates to requested flow rates after the particular water passage is shut off, and the engine water passage is connected to the heater water passage.

Abstract: There is provided a control system of a chemical heat accumulator which enables to facilitate small-sizing of the chemical heat accumulator by carrying out heat release and heat accumulation according to a degree of priority by appropriately selecting a location of carrying out the heat release and heat accumulation on priority basis. A chemical heat accumulator includes a valve mechanism which makes a plurality of reactors communicate separately with a reservoir, and cuts off the plurality of reactors from the reservoir. When both reactors are in a state in which an exothermic reaction between a reaction material and a reaction medium is possible, or in a state in which an endothermic reaction in which the reaction medium is desorbed is possible, a controller which controls an opening of a valve mechanism controls the opening of the valve mechanism such that a flow rate of the reaction medium circulated between the first reactor and the reservoir for which a degree of priority of heat release or heat accumulation is high becomes higher than a flow rate of the reaction medium circulated between the second reactor and the reservoir for which the degree of priority of heat release or heat accumulation is low.

Abstract: A vehicular heat management system is described and includes: a heater configured to carry out heating of a heat medium and stop the heating, and a heat exchanger configured to carry out heat exchange between lubricant oil for lubricating a speed change apparatus and the heat medium. A heat medium circulator is provided that is configured to switch the heat medium circulation state between a first circulation state where the heat medium circulates through the heater and the heat exchanger, and a second circulation state where the heat medium circulates through the heater and a heater core. An electronic control unit is also provided. When a pre-operation warm-up request to warm up the speed change apparatus and a pre-operation heating request to heat a vehicle cabin are both issued, the electronic control unit causes the heat medium circulator to switch the circulation state such that a warm-up of the speed change apparatus is carried out before heating of a vehicle cabin.
