Cooling air

[jdcarr]

Does anyone know of a commercial product or a cheap way of cooling an air flow. I have a flow of 500 litres/minute passing through a 1/4 inch diameter pipe. The inlet air can be up to 30 degC and I need to cool it down to approximately 15 degC.

The equipment preferably needs to be small.

Are you thinking along the lines of a liquid to gas heat exchanger and a water chiller? How small and how cheap does it need to be?

Not sure of your application but if it is for an air purge to an electrical or computer cabinet, maybe a vortex cooler is what you are looking for.

I was thinking of under £1000 and about a square foot in volume - possible?

Different application I'm affraid. We are passing the 500 litre/min air flow (from a mass flow controller) through a 'canister' as part of an accurate flow test station - therefore all the flow needs to be passed through any system.

The air flow has to be cooled from (hot) room temperature down to the 15 degC level before entering the 'canister'.

What is the pressure in the system so the quantity of heat removal can be calculated.

The flow is passed through a 'canister' which has a fitted fan, so essentially there is no static pressure i.e. no pressure drop.

A 4 bar air flow is passed into the mass flow controller which supplies the 500 litre/min flow .

I'm out of the office till Tuesday, but will log on then.
