Frequently Asked Questions
What does an air-cooled machine avoid?
The entire water side of heat rejection.
No cooling tower and no condenser pumps.
No water treatment regime to maintain.
No plant room dedicated to any of it.
It arrives as one item and sits outside.
What is given up in exchange?
Performance in hot weather.
It condenses against dry ambient air.
Condensing pressure rises as the day heats up.
Capacity and efficiency both fall.
That happens exactly when cooling is wanted most.
Which rating figure should be used?
The one at the local design ambient.
Standard rating conditions are milder than reality.
The gap between the two is often substantial.
Selecting on the headline figure undersizes the plant.
Ask for performance at the site condition.
What is recirculation and why does it matter?
The machine drawing its own discharge air back in.
Entering air temperature rises as a result.
Capacity falls with no fault to find anywhere.
Walls, screens and roof wells all cause it.
It is a siting problem, not an equipment problem.
How much clearance does the unit need?
What the manufacturer publishes, treated as a requirement.
The figures exist because of recirculation.
Adjacent units count as obstructions too.
Screening for appearance can defeat the machine.
Clearance is not an aspiration.
Is noise a real consideration?
Yes, because the machine lives outdoors near people.
Condenser fans and compressors both contribute.
Low-noise fan options exist at selection.
Attenuation can be built in from the start.
Adding it afterwards costs considerably more.
What does a free-cooling variant do?
It uses cool ambient air directly.
Compressors stay off while conditions allow.
In a temperate climate that covers many hours.
Loads that run year-round benefit most.
The saving depends on the local climate.
