Abstract: A heater apparatus includes a main body, a detecting unit, and a control part. The main body has a power supply part to which electric power is supplied and a heating portion connected to the power supply part to generate heat by electric power supplied from the power supply part. The detecting unit detects an object around the main body. The control part controls supply amount of the electric power to the power supply part. The control part controls the supply amount of electric power to the power supply part to be reduced compared with a normal state when the detecting unit detects that the object is within a predetermined range of the main body.

Abstract: A radiant heater air-conditioning system includes: a heater main body having a heating portion energized to generate heat so as to radiate a radiant heat into a vehicle interior; an energization setting unit that sets an energization enable state for enabling energization of the heating portion and an energization disable state for disabling the energization of the heating portion; and an air-conditioning control apparatus that controls an air-conditioning output of a heating operation in the vehicle interior. The air-conditioning control apparatus reduces the air-conditioning output when the energization enable state is set, compared with when the energization disable state is set.

Abstract: A radiant heater device has an electrode embedded in a substrate part and a plurality of heating parts. The electrodes are formed by material that has low specific resistance. An area occupied by the electrode is restricted. The heating parts are formed by material having high specific resistance in order to generate heat so that radiation is produced. The electrode and the heating part are electrically connected within the substrate part. The plurality of heating parts are arranged in parallel between a pair of electrodes. The electrodes and the heating parts are formed in a film-like shape, and the thermal capacity is reduced. As a result, a temperature of the heating parts rises promptly in response to a turning on of power. In addition, the temperature of the heating parts promptly decreases when an object comes into contact therewith.

Abstract: A radiant heater device includes: a heater main body having a heating portion that generates heat by being supplied with electric power to radiate radiation heat due to the heat supplied from the heating portion; an output control unit that controls an output of the heating portion; and a maximum output determination unit that determines an upper limit of the output of the heating portion depending on a heat load around the heater main body. The output control unit controls the output of the heating portion depending on the heat load not to exceed the upper limit of the output determined by the maximum output determination unit.

Abstract: A vehicle air conditioner includes a heating heat exchanger, a first temperature adjustment mechanism for adjusting a temperature of air to be blown toward a driver's seat side in a vehicle compartment, and a second temperature adjustment mechanism for adjusting a temperature of air to be blown toward a front-passenger's seat side in the vehicle compartment. In the vehicle air conditioner, the first and second temperature adjustment mechanisms are controlled to perform a one-seat priority mode control such that the temperature of air to be blown toward the front-passenger's seat side is lower than the temperature of air to be blown toward the driver's seat side, when only the driver is in the vehicle compartment and the heating condition is determined as the air conditioning state.

Abstract: When an air conditioning ECU determines that it is immediately before idling stop, the air conditioning ECU implements a front seat air conditioning mode even if the air conditioning ECU determines that an occupant intensive air-conditioning mode can be implemented. Accordingly, the air conditioning ECU controls opening and closing mechanisms so as to blow a conditioned air from driver's seat side outlet ports, and also blow the conditioned air from a passenger's seat side foot outlet port. Hence, in cooling operation, since a temperature increase of air drawn into an inside air inlet port is limited when the idling stop is carried out, temperature increase of air blown into the vehicle interior from the outlet port can be restricted. In other words, a temperature change in the vehicle interior can be limited when a travel engine stops due to the idling stop.

Abstract: A radiation heater apparatus has a plurality of heat radiation parts and a plurality of heating parts. A low thermal conductive part is formed between adjacent two of the heat radiation parts. The low thermal conductive part is provided with resin material which mainly forms a substrate part. The low thermal conductive part thermally isolates the heat radiation part by surrounding a periphery of the heat radiation part. As a body contacts with the surface of the apparatus, the thermal energy of specific heat radiation part directly under the body dissipates heat to the body. Furthermore, heat transfer from the periphery of the specific heat radiation part to the specific heat radiation part is reduced by the low thermal conductive part.

Abstract: When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.

Abstract: A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode.

In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature. Thus, an electric power consumed by an electric motor of a blower can be reduced, thereby realizing energy saving.
