Abstract: A frequency up and down converter, in which, when down converting a high frequency signal into an intermediate frequency signal or up converting an intermediate frequency signal into a high frequency signal by controlling switching elements using a local oscillator signal, a signal with a frequency to be converted is controlled a number of times during one cycle of the local oscillator signal, whereby the local oscillator signal with a frequency lower than an original frequency may be used. Transistors are added in parallel to switching transistors disposed in a frequency down conversion unit or a frequency up conversion unit, and local oscillator signals with predetermined phases and pulse widths are provided to the gates of the transistors such that a high frequency signal or an intermediate frequency signal is transferred to an output terminal at least two times during one cycle of a local oscillator signal.

Abstract: The present invention relates to a method for controlling a vehicle air-conditioner, which can prevent undershoot of an evaporator by performing a maximum capacity control or controlling an discharge capacity of a compressor through the outputting of an discharge capacity control value of the compressor directly before the stop of the air conditioner, and can improve the pleasant feelings of the passengers by preventing delay of response, which converges into the target temperature of the evaporator due to the delay of the decrease of the temperature of the evaporator.
