Cooling basics

Heat capture

Types of air cooling heat exchangers

Water based

  • Treated water
  • Brine
  • Glycol-water mix

Direct Expansion (DX) Refrigerant gas

What’s the difference?

From outside they look the same.

Liquid Cooling Package (LCP) Vs Direct Expansion (DX)
It’s what’s inside that makes a big difference.

All LCP units contains pressurized
water-based liquids…
Leaks are always a possibility

Refrigeration Systems Conception – Canada

DX units contains only pressurized refrigeration gas. Leaks cannot arm electronics.

Okay, so…what’s out there?
LCP units might be convenient but require floor or cabinet space

Refrigeration Systems Conception – Canada

But also require a big infrastructure…
A chiller is required for LCP units to function and is an expensive way to provide cooling. If even available.

Okay, so…what’s out there?

Direct Expansion (DX) units.

  • Mini-split wall mounted

  • Water-cooled air-conditioner ducted or not

  • Commercial split unit ducted

Commercial rooftop air- conditioner ducted

What’s the difference?

Split units require refrigeration piping between the indoor an outdoor unit. They reject heat via an air cooled condenser outside.

Water-cooled units reject heat via a water condenser built-in. They waste a huge amount of potable water to function.

What’s the difference?

Rooftop air conditioners are self-contained units but require ductwork to reach the room

Commercial split units also require piping and ductwork to function

What’s the difference?

Most air conditioning units are not equipped and designed to function during winter or cold weather. Frozen units are a regular source of expensive failures and extended periods of down time.

CompuCool DX was specialy desing and tested in the harshest weather conditions and can function reliably from +40*C to -40*C.

Ok, so what about the CompuCool DX?

CompuCool DX is a split type, Direct Expansion gas refrigerant based system.

CompuCool DX reject heat via a specialised outdoor condensing unit.

CompuCool DX Features an Innovations

The CompuCool DX as a ‘sit-on-top’ approach to the cooling solution. This configuration is directly cooling the equipment inside the cabinet and as no effect on the room or the building cooling-heating system. This configuration is designed to fit in a 8’ ceiling room without any loss of space inside the cabinet.

The main benefit from the ‘sit-on-top’ approach is that every equipment inside the cabinet will be supplied with cold air from the positively pressurized front of the cabinet.

The cold air will naturally move through every piece of equipment from the positive pressure of the cabinet front to the negative pressure from the back.

So no equipment ‘Hot Spot’ anywhere inside the cabinet. Temperature is also balanced from top to bottom.

Most equipment discharge heat from the back and is quickly absorbed by the CompuCool DX unit. No more heat, no more worries.

Capacity Modulation

Most air-conditioning units do not modulate. They simple cycle on and off to maintain temperature. Some do modulate, but cannot maintain low capacity for extended periods of time. The capacity of theses units are critical. A too small unit will not do the job, a too big unit will burn-out components by ‘short-cycling’.

CompuCool DX as the ability to modulate it’s capacity continuously. So adding or removing equipment as no impact as long as you stay in the 5 to 10kW/per unit bracket.

Multiple CompuCool DX natural redundancy

In most cases, cabinets are not rejecting a full 10kW of heat each. Installing multiple CompuCool DX in a single row creates a single entity that can compensate if one unit fails.

If a failure occurs, the remaining units will compensate by raising their capacity to capture the extra heat

Optional Cold Aisle / Hot Aisle application

In existing rooms or when cooling the whole room is required, CompuCool DX also offers a cold/hold aisle configuration. Created with creature comfort in mind, a unique diffuser provide a gentle and efficient cold air curtain in front of the equipment and draws hot air from the back.

Open air cabinets and H-frames can be cooled efficiently with all the benefits of CompuCool DX.
