ADAP-KOOL® the way you work

Adapting to a changing world for over 30 years with

state-of-the-art refrigeration control systems

Save energy and enhance food safety

with adaptive control algorithms

ADAP-KOOL® is a family of high-end

adaptive refrigeration controls developed

by Danfoss for all food retail applications.

First introduced in 1987, Danfoss ADAP-

KOOL® products have a long history of

adapting to change. And ever since their

introduction, the solutions have been

defined by the same basic values: robust,

reliable, and adaptive display-case and

cold-room refrigeration that ensures high

food safety and significant energy savings.

Robust and reliable control

A robust adaptive superheat algorithm

can save 8-12% of energy use by ensuring

the evaporator is always fully utilized

under all conditions. But it requires several

components to work together perfectly,

and each new advance in technology

makes a system more complex.

This is where modern case control solutions

make the difference. As refrigeration

technology gets more sophisticated, you

can rely on ADAP-KOOL® case control

to handle that complexity - optimizing

efficiency and supporting valuable

decisions.

The power of adaptive

refrigeration

If operating conditions in food retail

refrigeration never varied, setting up a

refrigeration solution would be a lot easier.

But conditions do change, and that means

constantly fluctuating system loads.

To optimize refrigeration efficiency,

ADAP-KOOL® avoids the “one size fits all”

approach. With adaptive controls, you don’t

need to manually adjust system operation

for changing conditions.

Over the decades, data from thousands of

installations have proved the superiority of

adaptive superheat control.

In refrigeration, superheat is the temperature

difference between the actual temperature

of the refigerant vapor and its saturation

temperature.

For every Kelvin the superheat can be

decreased, there is an equal potential to

increase the evaporating temperature. For

every Kelvin the evaporating temperature

is increased, 2-3% energy can be saved in a

refrigeration system.

Danfoss Adaptive Minimum Stable

Superheat Control (MSS)

With MSS, utilization of the evaporator

surface is maximized while ensuring that

no liquid exits the evaporator.

The MSS algorithm, in combination with

suction pressure optimization, delivers

maximum system efficiency in systems

with dry expansion.

The new Danfoss ALC algorithm provides

the highest utilization of evaporator

capacity, enabling up to 5 Kelvins higher

suction pressure compared to MSS control

and even twice as much compared to

systems with fixed superheat.

The name

“ADAP-KOOL®” is a

shortened adaptation

of the phrase

“adaptive cooling”

Danfoss Adaptive Liquid

Control (ALC)

The ALC algorithm typically used in

transcritical CO

systems with a suction

accumulator and liquid ejectors, injects

greater amounts of refrigerant into the

evaporator, fully utilizing the entire surface.

Increasing the amount of the refrigerant in

the evaporator increases the evaporation

temperature, bringing the superheat very

close to zero.
