Abstract: A battery pack temperature regulating apparatus includes an evaporator configured to cool air inside a battery casing receiving a battery used for driving a vehicle; an evaporator casing receiving the evaporator; and a heater attached to the evaporator casing and configured to heat the air inside the battery casing.

Abstract: A refrigerant circulation apparatus includes: a vehicle-interior air conditioning (2) that cools an interior of a vehicle; an on-vehicle battery cooler (3) that includes an evaporator for on-vehicle battery cooling (32) that cools an on-vehicle battery mounted on the vehicle; and an electric compressor (5) that compresses and supplies a refrigerant to at least one of the vehicle-interior air conditioning (2) and the on-vehicle battery cooling (3). The apparatus also includes: a temperature sensor (41) that detects a temperature of the electric compressor (5); a pressure sensor (42) that detects a pressure of the refrigerant compressed by the electric compressor (5); and a control unit (40) that restricts operation of the evaporator for on-vehicle battery cooling (32) to reduce load on the electric compressor (5) based on the temperature of the electric compressor (5) and the pressure of the refrigerant.

Abstract: A vehicle heating system comprising: a coolant circuit that circulates coolant between an engine and a heater core; heating device that heats coolant, which is interposed in the coolant circuit; a pump for coolant circulation, which is interposed in the coolant circuit; and a switching valve that switches the coolant flowing through the coolant circuit between a heater-core-side circuit that circuits the coolant among the heater core, the pump and the heating device and an engine-side circuit that circulates the coolant into the engine, wherein the switching valve has a thermo valve that switches channels so that the coolant coming from the engine-side circuit enters either one of the heater-core-side circuit and the engine-side circuit according to temperature of the coolant, and a bypass that delivers the coolant, which comes from the heater-core-side circuit, to the heater-core-side circuit.

Abstract: A power switching apparatus, configured to switch a power supply source that is configured to supply an electric power to an air conditioner that is mounted on a vehicle that can receive a power supply from a plurality of power sources, includes: a selecting unit configured to select the power supply source during execution of pre-air conditioning in which an operation of the air conditioner is started before start of running of the vehicle; and a setting unit configured to set a power supply to be supplied from the power supply source that is selected by the selecting unit, to the air conditioner.

Abstract: Provided are an evaporator unit for vehicle-interior air conditioning 2 for cooling an interior of a vehicle, an evaporator unit for on-vehicle battery cooling 3 including an evaporator for on-vehicle battery cooling 32 for cooling an on-vehicle battery mounted on the vehicle; an electric compressor 5 for compressing and supplying a refrigerant to the evaporator unit for vehicle-interior air conditioning 2 and the evaporator unit for on-vehicle battery cooling 3; a temperature sensor 41 for detecting an inner temperature of the electric compressor 5; a pressure sensor 42 for detecting a pressure of the refrigerant compressed by the electric compressor 5; and an air-conditioning control unit 40 for restricting operation of the evaporator for on-vehicle battery cooling 32 so as to reduce load on the electric compressor 5 based on the inner temperature of the electric compressor 5 and the pressure of the refrigerant.

Abstract: A dozing preventive device and its method are disclosed, in which the user does not have to move to a specific place for dozing prevention, and neighboring people are not disturbed. The dozing preventive device is small and is simple in its construction so that the user does not have to use his hand for supporting the device. The dozing preventive device comprises: a contacting portion directly contacting with the teeth of a user; a vibration mechanism for vibrating the contacting portion; a power supply for driving the vibration mechanism; and a housing case for accommodating the vibration mechanism and the power supply as well as for supporting the contacting portion. The dozing preventive device is brought into contact with the teeth of a user so that the vibration is transmitted to the user's brain, thereby preventing the user from sleeping.

Abstract: In a vehicular air conditioner, in which an air flow passage for directing air sucked horizontally through a suction port upward in a casing having a plurality of blowout ports at the upper part and said suction port at the lower part, and an evaporator, air mix damper, heater, and blowout mode switching damper for selectively switching the plural blowout ports are arranged in the air flow passage, the evaporator can be replaced easily and rapidly, and the contamination of the surroundings, caused by the drain which drops from the evaporator when the vehicle is inclined and flows back into the blower case and drops from it by leaking, is prevented.
