These cooling coils transfer sensible heat and latent heat from the air to the chilled water, thus cooling and usually dehumidifying the air stream. Is an “air-cooled condenser” any outdoor condenser up to and including an air-cooled chiller? You’ll also find these valves on all major components such as pumps and AHU’s.
In this article we’l be covering chilled and condenser water schematics to learn how to read them, how to identify the main components and symbols as well as real world examples, additionally we’ll cover the purpose of the main components and different design types. If the flow rate is high In the secondary loop then all the chilled water will flow into the secondary loop and the return line will flow straight back to the chillers.
[1][2], Chilled water is used to cool and dehumidify air in mid- to large-size commercial, industrial, and institutional facilities. Danfoss Learning has are hundreds of courses available in a variety of languages. Now that you know how a chiller works, you may be considering your process chiller system options. Sometimes they will show the connection to the main AHU’s other times they will refer you to a separate drawing to see this detail. The capitalised letters of “NC” will mean the valve is normally closed. The refrigeration circuit is made up of four components: the compressor, the condenser, the expansion valve and the evaporator. The thermodynamic cycle of an absorption chiller is driven by a heat source; this heat is usually delivered to the chiller via steam, hot water, or combustion.
At Trane Supply, we have the parts and the knowledge to support all Industrial chillers typically come as complete, packaged, closed-loop systems, including the chiller unit, condenser, and pump station with recirculating pump, expansion valve, no-flow shutdown, internal cold water control. This article was really helpful for understanding it better! On the outlets of the header you might find a commissioning station or double regulating valve but in newer systems this is likely on the return line.
That's why YORK® created a centrifugal chiller that handles a project's unique variables – the YORK® YK Centrifugal Chiller. These cookies will be stored in your browser only with your consent. Then we’ll have some pressure gauges to allow manual readings. They are often used in the plastic industries, injection and blow molding, metal working cutting oils, welding equipment, die-casting and machine tooling, chemical processing, pharmaceutical formulation, food and beverage processing, paper and cement processing, vacuum systems, X-ray diffraction, power supplies and power generation stations, analytical equipment, semiconductors, compressed air and gas cooling.

You can see the direction of flow in the pipe which is indicated by arrows. In the case of chillers, heat is taken from the fluid being chilled and transferred to the ambient air. help you be more productive, profitable, and knowledgeable. They are easy to install, remove and relocate and will not disrupt the layout of your current system. Large chilled water hoses are used to connect between rental chillers and air conditioning systems.[5]. the hard questions – we’re ready!
The fluid circuit carries the process fluid around the object being cooled. And the eLessons cover a wide range of topics, including, of course, chillers. Then connect those pumps to the condenser inlets and another line out of the condenser and up to the cooling towers, located on the roof. Along with our technical expertise, we focus on providing customers
I always start by locating the chillers, the pumps, the risers, AHU’s and cooling towers. We engineered an unprecedented array of innovations into an integrated design that delivers superior performance with efficiencies as low as 0.20 kW/ton (17.6 COP). There might also be a bypass line with a motorised valve across the cooling towers flow and return. [4], When the chillers for air conditioning systems are not operable or they are in need of repair or replacement, emergency chillers may be used to supply chilled water.
Heritage Parts is a trusted distributor of Avanti replacement parts. Your videos are always informational, thanks for sharing so much information. The main chiller components are the Compressor, Condenser, Evaporator, Expansion Valve, Power Panel, Controls unit and the Water Box. Again these become less reliable over time and can become stuck. The process fluid absorbs heat from what is being cooled and then goes through the chiller where the heat is removed from the fluid and transferred to the ambient air. Water boxes are mounted to the evaporators and also the condensers of water cooled chillers. The evaporator is where the refrigerant starts evaporating back into a gas.
In this article we will learn how to locate these on the chiller and briefly what their purpose is.
