A first fan controlling section of a controller circuit is configured to control a first blower fan so as to induce the discharge of the airflow of a cool air through a first air outlet defined in a first enclosure of an indoor unit of the air conditioner. A second fan controlling section is configured to control second blower fans so as to induce the discharge of the airflows of a room air through second air outlets, respectively, defined in a pair of second enclosures disposed on the opposite sides of the first enclosure. An enclosure attitude controlling section is configured to change the respective attitude of the second enclosures relative to the first enclosure.

Controller circuit for air conditioner with cool air guided with room temperature airstream

An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.

Room air conditioner with movable side fan units

An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The heat exchanger includes a rear section having a length larger than that of a front section in the longitudinal direction of the air outlet. The rear section extends into at least one of spaces respectively defined behind the fan units.

Air conditioner

In a method of producing dialkylcarbonate, alcoholic compound and cyclo-carbonate are subjected to a catalytic reaction each other at a reaction temperature of 20.degree. to 200.degree. C. and under a pressure of 0 to 40 kg/cm.sup.2 G, which keeps the reaction system liquid, in the presence of ion exchanged zeolite which is ion-exchanged with alkali metal ion and/or alkaline earth metal ion.
