| 简介 |
PURPOSE : A power saving freezing circuit is provided to increase the cooling efficiency by dehumidifying cold air cooled with a primary evaporator through a re-heating coil and cooling and dehumidifying heated air through a secondary evaporator.
CONSTITUTION : An evaporator is divided to a primary and a secondary evaporators(13, 15). A re-heating coil portion(17) is arranged between the primary and the secondary evaporators. Indoor air sucked by a blowing fan(19) is cooled with the primary evaporator and exchanged heat to air with a middle temperature and a middle humidity. The air of low temperature is dehumidified through the hot re-heating coil portion by the blowing fan. The secondary dehumidified air is cooled and discharged by the second evaporator through a third expansion valve(43). Thereby, the low humidity is maintained and the energy consumption is reduced by increasing the cooling efficiency of a freezing circuit.
