查询词典 cooling by means of air

First, a system for providing liquid refrigerant subcooling (10), subsequent to the subcooling accomplished by the primary condenser of an air conditioner, refrigeration or heat pump system, by means of evaporative cooling utilizing the condenser water of said air conditioner, refrigeration or heat pump system and/or some other water supply to wet the surface of the subcool heat exchanger and then passing the cold, dry building exhaust air (13) required for good indoor air quality across the wetted surface of the subcool heat exchanger or by using building exhaust air only to conductively subcool.

首先，一个提供液态制冷剂过冷的系统(10)，在由空调、制冷或热泵系统的主冷凝器实施完成过冷之后，通过蒸发冷却，利用所述空调、制冷或热泵系统的冷凝器水和/或一些其它水源来润湿过冷热交换器表面，然后使为达良好质量室内空气所需的建筑物干冷排气(13)通过穿过过冷热交换器的润湿表面，或只利用建筑物排气以传导方式过冷。
