A condenser is a tool that’s used to liquefy fuel by cooling it. In HVAC tools, scorching discharge fuel (refrigerant vapor) from the compressor enters the condenser coils on the high and is condensed, drains out of the condenser to a receiver positioned close to the underside. The condenser coil is positioned together with the compressor and controlling gadgets within the condensing unit. In a distant or break up system air-con set up, the condensing unit is positioned open air. Condensers can be found in a wide range of sizes and designs that embody plain tube, finned tube and plate kind, series-pass and parallel cross items.
Condensers are labeled by their cooling technique. The three foremost sorts are damaged all the way down to:
- Air-cooled condensers
- Mixed air and water-cooled condensers
- Water-cooled condensers
An air-cooled condenser consists of a coil of ample floor that air is blown by a fan or induced by pure draft. The sort of condenser is universally utilized in small capability refrigerating items. Largely designed for residential or small workplace air conditioners.
Air-chilled condensers ought to be stored from free from dust, lint and different overseas supplies as a result of they have an inclination to cut back the airflow across the tubes and fins if they’re allowed to build up similar to evaporators.
Mixed Air- and Water-cooled Condensers
The sort of condenser can be know as an evaporative condenser and consists of a coil cooled by water sprayed from above after which chilly air enters from the underside and is blown throughout the coils. As water evaporates from the coil it creates a cooling impact that condenses the refrigerant inside the coil. The refrigerant fuel within the coil is scorching which modified to the liquid state by combining the sprayed water and the big column of transferring air equipped by the fan. The water that doesn’t evaporate is recirculated by the use of a pump.
A water-cooled condenser is just like a steam floor condenser in that cooling is achieved by water alone that circulates via tubes or coils enclosed in a shell. IN a water-cooled condenser the refrigerant circulates via the annular area between the tubes or coils. Due to its development, a water-cooled condenser can be known as a double-pipe condenser.
As a result of an evaporative condenser isn’t wasteful of water, massive compressor installations are doable in areas the place water is scarce. Checks have proven that the quantity of water required won’t exceed the.03 gpm per ton of refrigeration. This is without doubt one of the eco-friendly causes to make use of such a condenser. Evaporative condensers additionally eradicate water water disposal issues and supply essentially the most economical technique of cooling refrigerant gases of ordinary air conditioners.
