A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycle. Chilling water can be used in heat exchangers to transfer the heat from process fluids, which improves the efficiency of various systems.
A chiller is a machine that removes heat from liquid. It uses one of three methods: vapor compression, adsorption refrigeration or absorption refrigeration to accomplish this. Chilling can be used to produce cold water or refrigerant-grade chilled water, depending on the design of the machine.
A chiller is a machine that removes heat from a liquid coolant via an evaporation-condensation refrigeration cycle. Chilled water (usually a mixture of water and ethylene glycol) is circulated through the building's air conditioning system or directly to heat-producing machines, such as servers and chillers.
Chiller is a cooling machine that removes heat from the carrier liquid via vapor compression, absorption or adsorption refrigeration cycle. A chiller consists of heat exchanger that extracts heat from the process medium, compressor that compresses the refrigerant gas for further cooling and expansion valve for releasing gas into atmosphere when system condenses after absorbing heat from process medium.
Chilling units remove heat from the coolant to either air or liquid. They can use chilled water as the heat transfer medium, or they can be used in freeze protection applications where there is no need for heating and ice forming is not an issue. Cooling towers are shell and tube heat exchangers with a long coil inside a tank filled with water that evaporates in part because of the heat put into the water by chiller and then condenses on the surface area of the coil itself. Air wet cooling towers work by having cool water spray over air which passes through an air receiver at the bottom of tower, thus decreasing its temperature, which then goes up through openings in top of tower.
Chillers are a large piece of machinery designed to cool down liquids. They are a necessary component in any refrigeration system and can be found in large scale commercial installations, or small scale residential units.
سیستم های چیلر آب خنک دارای برج خنک کننده هستند، بنابراین راندمان بالاتری نسبت به چیلرهای هوا خنک دارند. چیلرهای آب خنک کارآمدتر هستند زیرا بسته به دمای حباب دمای محیط که کمتر از دمای حباب خشک محیط است متراکم می شوند. هر چه یک چیلر کندانس کمتری داشته باشد، کارایی آن بیشتر است. این سیستم دارای چندین جزء ضروری از جمله:
