Abstract: A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

Abstract: A heat storing system includes: a heat source that emits heat to a first thermal medium; and a heat storing unit. The heat storing unit includes a heat storing body container housing a heat storing body, and a thermal medium container housing a liquid phase thermal medium. The heat storing body stores or emits heat in accordance with phase change of the heat storing body. The heat storing unit is configured to conduct a cold heat emission mode in which the liquid phase thermal medium and a cooling medium exchange heat in the thermal medium container to evaporate the thermal medium such that cold heat is emitted to the cooling medium.

Abstract: A vehicle air conditioning apparatus is provided that can prevent temperature variations of the air after the heat exchange in a radiator to reliably control the temperature of the air supplied to the vehicle interior. During the heating operation and the heating and dehumidifying operation, target degree of supercooling SCt when target air-blowing temperature TAO is a predetermined temperature or higher is set to SCt1 that is greater than SCt2 when the target air-blowing temperature TAO is lower than the predetermined temperature. When amount of air Ga supplied from indoor fan 12 is lower than a predetermined value, the target degree of supercooling SCt is corrected, which is set such that the degree of supercooling is lower than target degree of supercooling corrected when the amount of air Ga supplied from the indoor fan 12 is a predetermined value or higher.

Abstract: An adsorption based system is provided for the selective cooling and heating of a vehicle compartment using by-product water collected from a power generating unit of a vehicle. The system may include a fuel cell stack and an exhaust conduit configured to transfer an exhaust stream from the fuel cell stack. A water reservoir stores by-product water collected from the exhaust stream. The system may include a coolant loop configured to circulate a coolant fluid. A detachable adsorption subsystem is in thermal communication with the coolant loop and the exhaust conduit, and may include an evaporator and an adsorbent bed. The adsorption subsystem is configured to: vaporize water from the water reservoir using the evaporator; adsorb the vaporized water, thereby cooling a portion of the coolant fluid; regenerate the adsorbent bed using heat from the exhaust stream to release water vapor; and direct the water vapor into the exhaust conduit.
