Dx Water Cooled System

The cooling shelf systems are available in 2 3 and 4 nominal ton capacities in air cooled split systems or water cooled self contained systems.

Dx water cooled system.

The dx system works in such a way that the evaporator is located in the space to be refrigerated. Chilled water fan coil unit. Condenser coils are constructed of 5 8 o d. Dual cooling chilled water air cooled refrigeration providing full and partial free cooling.

In case of the chilled water system the refrigeration system is used to first chill the water which is then used to chill the air used for cooling the rooms or spaces. Water cooled mini dx system. In the dx system the air used for cooling the room or space is directly passed over the cooling coil of the refrigeration plant. Liebert pdx compact dx cooling system 11 29kw.

Earthwise ice enhanced air cooled chiller plant. A packaged dx system also contains all components of the system in a single unit but in some packaged systems the evaporator compressor and condenser are located outside the building and the unit pumps cooled air into the building through ducts. The direct expansion dx and chilled water central air conditioning plants are both used at different places depending on the applications and size of the place to be air conditioned. The dx air conditioner system uses a refrigerant vapor expansion and compression cycle to cool air coming in through a supply plenum and returns it to the area that needs cooling through the return.

And glycool fluid cooled economizer and dx refrigeration system. The unit effectively circulates refrigerant through a series of condensers and evaporators which warm air moves through and is cooled down before being pushed through the return. The units feature variable speed ec fans that. Both of them have their own advantages and disadvantages.

The direct expansion system in hvac has been growing rapidly due to its ability to get rid of most duct work and piping. Intelligent variable air system for packaged dx applications. Let us see the comparison of dx and chilled water central air conditioning plants. Standard sizes of evaporative cooled condensers are available from 50 to 400 tons and custom sizes up to 1000 tons.

Blue star introduces water cooled mini dx units with a capacity range of 1tr to 2 5tr in addition to the existing range of 3tr to 16 5tr watercooled ducted packaged units to suit the small air conditioning applications. These are unitary air conditioning units with compact design. Shelf system units are front access only. The popularity of this system is because the installation work has been made easier hence reducing the cost of the overall system.

The tubes are supported by high temperature glass reinforced plastic tube sheets.
