A Study on the Superheat Control of a Tandem-type Airconditioner by Using a Variable Speed Outdoor Fan

변속실외기펜을 사용한 텐텀형냉방기의 과열도제어에 관한 연구

For the safe operation of an air conditioner, the liquid car η 'over to compressors should be minimized and compressors should be operated in the specified region of suction and discharge pressures recommended by compressor manufactures. In this study, a capillary assisted tandem-type airconditioner was considered. A variable speed outdoor fan was used to control operating points of the system. Test results showed the possibilities to move system operating points to the safe region by controlling the speed of an outdoor fan.
