Abstract: An inexpensive warm-up apparatus for an internal combustion engine having a simple structure and eliminating the need of forming a hole in a heat storage material retainer or the need for a seal around the hole or an electrical circuit. A heat storage material retainer (14) accommodating a latent heat type heat storage material (X) is arranged in a water jacket (13). The heat storage material retainer (14) has a nucleation device (2) that accelerates phase transition of the heat storage material in a supercooled state.

Abstract: A control apparatus and method for controlling an automotive heater apparatus. The heater apparatus includes a coolant circuit for cooling an engine, a coolant circulating through the circuit, a heat generator for transferring heat to the coolant, and a heater core for transferring heat from the coolant. The heat generator houses a viscous fluid and a rotor selectively connected to and disconnected from the engine by a clutch. The clutch connects the engine with the rotor to shear the viscous fluid and generate heat. When the rotating speed of the rotor exceeds a rotor speed limit, which varies in accordance with the detected coolant temperature, the clutch disconnects the rotor of the heat generator from the engine and de-activates the heat generator.

Abstract: Usage of a conductive heat source generated by heating compressed air, wherein compressed air obtained by compression by a compressor is sent into a compressed air heater having an electric heater incorporated therein, so as to be heated, and the compressed air thus heated is fed into a steel pipe arranged in a green house for forcing culture of vegetables or in other rooms, a compressed air exhaust port provided at the end of this steel pipe being inserted into a water tank so that, with the pressure of the compressed air inside the steel pipe always kept a little higher than the atmospheric pressure, a heat thus generated is conducted to the entire pipe wall of the steel pipe and radiated to inside of said room from this pipe wall to which the heat is conducted.

Abstract: A gas fire space heater which can be an insert for an existing fireplace or a free standing unit is described. The device consists of a gas burner with radiants disposed within a housing. The products of combustion are collected in a first plenum, directed through a concertina heat exchanger into a second plenum, and from the second plenum up a flue. Air to be heated is collected by a blower and circulated countercurrently to the products of combustion through the heat exchanger, around the housing, and into the space to be heated. Air to be heated is supplied to the blower from an outside vent, and an inside vent. The outside vent is controlled by a one-way suction damper and the inside vent is controlled by a manual damper. The two vents form a T at the fan inlet and control of the manual damper then controls the amount outside and inside air supplied to the blower.

Abstract: The invention is an energy recovery system (20) which uses excess air emanating from an aircraft cabin (16) to drive a turbo-compressor unit (30). The outlet air from the compressor (26) of turbo-compressor unit (30) is optionally fed, either around or through heat exchanger (24), back into the aircraft cabin (16) inlet line, reducing the amount of bleed air required to power the aircraft ECS. Mass flow sensors (34) and (38) are used, via flow control valve (36) and flow control valve control unit (40), to monitor and control the amount of engine bleed air required at any point in time to satisfy overall ECS requirements. The energy recovery system (20") may be utilized in conjunction with a motor driven cabin compressor (42) to reduce the output air requirements of the compressor and thus the weight and horsepower requirements of the compressor motor.
