The chiller is the section of the system where an exchange of heat occurred between the water that goes to the building and the evaporator. The water leaves the chilled water evaporator at 45°F or 7°C. This chilled-water is then circulated through the entire building by the use of a pump.
How Works How the Ecodry Closed-Loop Dry Cooling System Works. By taking advantage of the ambient temperature and without the utilization of compressors, the Ecodry system represents the simplest, most efficient, clean, safe and affordable equipment for any process or facility requiring water cooling at temperatures of 30°C (85°F) or higher.
There are six basic types of liquid cooling systems: Liquid-to-liquid; Closed-loop dry system; Closed-loop dry system with trim cooling; Open-loop evaporative system; Closed-loop evaporative system; Chilled water system . Liquid-to-Liquid Cooling Systems. The simplest of these systems is a liquid-to-liquid cooling system.
An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by exploiting water's large enthalpy of vaporization.
Well there are two types of refrigerant used in automotive systems, R-12 which has been widely used on earlier models and the more evironmentally.
