A fuel cell apparatus may include a stack, a reformer configured to generate reformed gas, a burner, a water supply tank configured to store cooling water, a burner air blower configured to draw in external air and then to blow the air, a vertex tube configured to convert the air into heated air and cooled air, a three-way valve configured to supply the air from the burner air blower selectively to the vertex tube or the burner, a first heat exchanger configured to exchange heat between the air discharged from the vertex tube and the cooling water, a second heat exchanger configured to exchange heat between the air discharged from the vertex tube and the reformed gas, and a four-way valve configured to supply the heated air and the cooled air to the first and second heat exchangers.

Fuel cell apparatus and method for controlling the same

The present invention relates to a gas heat pump and a control method therefor and, according to the present invention, the method for controlling a gas heat pump, which comprises an ignition plug and a gas engine having an engine combustion unit including a plurality of combustion spaces, may include: a target setting step of setting a target ignition energy amount on the basis of a refrigerant load amount determined according to a driving condition of the gas heat pump; an ignition step of igniting fuel injected into the combustion spaces; a comparison step of comparing an output energy amount emitted in the ignition step with a target ignition energy amount set in the target setting step; and a step of changing an energy amount required to ignite the fuel when the output energy amount and the target ignition energy amount do not coincide in the comparison step.

Gas heat pump and control method therefor

An air conditioner is provided that includes a filter, a filter cleaning unit having a space formed therein to place foreign matter separated from the filter, a moving mechanism to make the filter cleaning unit move along the filter, the moving mechanism including a first gear having a closed loop section shape with gear teeth formed at at least one of an outside circumference or an inside circumference, a gear guide to guide the first gear to rotate while maintaining at least one linear portion, a second gear engaged with the first gear, a drive source to make the second gear rotate, a third gear engaged with the linear portion of the first gear, and a connection mechanism connected both to the third gear and the filter cleaning unit to make the filter cleaning unit move, thereby permitting to make the moving mechanism compact and enhancing reliability.

Air conditioner

Provided are an air-conditioner and a controlling method thereof. The air-conditioner includes a blower fan forcibly generating a flow of air, a filter disposed on a flow path of the air that forcibly flows by the blower fan, and a vibration actuator disposed on a side of the filter. The method for controlling an air-conditioner includes disposing a collection part under a filter of an air-conditioner, vibrating a vibration actuator disposed on a side of the filter, and separating the collection part from a lower side of the filter.
