Abstract: Disclosed is a method for controlling cooling/heating of a heat pump system comprising the steps of: (a) controlling a compressor so that a flow rate of a refrigerant is reduced when the heat pump system is switched from a cooling mode to a heating mode or from the heating mode to the cooling mode; and (b) controlling a four-way valve so that a flow direction of the refrigerant is converted into an opposite direction when the flow rate of the refrigerant is reduced after the step (a).

Abstract: The object of the present invention is to prevent refrigerant from flowing out into a vehicle compartment due to damage to an evaporator or piping associated therewith. A solenoid valve is arranged at an inlet of an evaporator, and a check valve is arranged at an outlet of the evaporator. When operation of a system is to be stopped, the solenoid valve is closed while a compressor is kept operating for a predetermined time to suck out refrigerant from the evaporator to a downstream side of the check valve, so that during stoppage of the operation, the check valve prevents the refrigerant from flowing back into the evaporator. Thus, even if the evaporator arranged in the vehicle compartment or piping associated therewith is damaged, a situation where a large amount of refrigerant flows out of the evaporator into the vehicle compartment does not occur because no refrigerant remains in the evaporator, making it possible to prevent occupants in the vehicle compartment from being put in a grave situation.

Cylinder pressure is detected by a pressure sensor installed in each cylinder in an internal combustion engine. AS the occurrence or non-occurrence of heavy knock is determined based on the ratio between the maximum value of cylinder pressure fluctuation and the maximum value of cylinder pressure divided by a prescribed value, it becomes possible to detect the occurrence of heavy knock quickly. If it is determined that heavy knock has occurred, a knock suppression measure involving, for example, reducing the spark advance angle, is immediately applied, thus preventing damage to the internal combustion engine.
