Another open loop system is the ice builder, which is made of steel or copper coils submerged in a tank of water.

Air Separator are used with these tanks to facilitate Separation of dissolved air from chilled water so that it can be removed along with air bubbles present in chilled water. It ensures good heat transfer & long trouble free life in the chilled water lines in addition to reduction in noise.

For chilled water systems, locate the separator in the return to the chiller. In wall-hung boiler installations, it is convenient to mount the air separator in the vertical hot water supply pipe, as shown in the figure below. Of course, not all jobsite piping arrangements allow ideal installation of the air separator.

The flow of chilled water in the primary loop of a P/S system is constant, while two-way valves and variable-speed-driven pumps in the secondary loop control coil capacity by varying water flow.

Air-Cooled Water Chiller : Animated Schematic to 30 Tons. Compressor (#1) The compressor has two functions in the refrigerant cycle. First, it removes the refrigerant vapor from the evaporator and reduces the pressure in the evaporator to a point where the desired evaporating temperature can be maintained.

air-free water to the outer portion of the tank and allowing the lighter air-entrained water mixture to move into the lower velocity center. At the centre of the vortex the air is released from the water forms bubbles and exits

The Closed Loop design negates the need for high volume storage by utilizing inline air separation and thermal expansion control. In a Closed Loop configuration, the process cooling water is continuously maintained at desired temperature by utilizing closed circuit cooling towers, chilled water, or …

Jan 27, 2007· Air separators are mandatory in large chilled water systems. Even in smaller systems, when all the air is purged out during initial filling, the amount of air which can be dissoloved in the water differs according to the pressures i.e. at certain pressures the water can't dissolve the air.

Chilled Water Central Air Conditioning Plants. The chilled water types of central air conditioning plants are installed in the place where whole large buildings, shopping mall, airport, hotel, etc, comprising of several floors are to be air conditioned.

B&G Rolairtrol Air Separators for Hot/Chilled Water The Rolairtrol is an ASME vessel designed to create a low velocity vortex for air removal from circulating water.

The Bell & Gossett Rolairtrol® is a patented centrifugal style air separator for use in any HVAC system. Its 3-to-1 body diameter to nozzle diameter ratio slows the fluid velocity to help entrained air come out of solution, while its tangential inlet and outlet nozzles induces centrifugal fluid flow.

Expansion tanks are required in a closed loop heating or chilled water HVAC system to absorb the expanding fluid and limit the pressure within a heating or cooling system. A properly sized tank will accommodate the expansion of the system fluid during the heating or cooling cycle without allowing the system to exceed critical pressure limits.
