PRIMARY (DX) REFRIGERATION SYSTEMS

SECONDARY REFRIGERATION SYSTEMS

100% Refrigerant Charge from Compressors to Condensers to

Evaporators

Very Small Refrigerant Charge – Chilled HYCOOL Pumped to Room Coils

PRIMARY (DX) REFRIGERATION SYSTEMS

� The primary refrigerant (NH3, R404A, R22, etc) is sent

to all zones and fills the entire system at high pressure.

� Refrigerant changes state (liquid to vapor) in the

room/zone evaporators.

SECONDARY REFRIGERATION SYSTEMS

� The primary refrigerant is confined to the chiller,

utilizing a very small charge of refrigerant.

� A secondary fluid is chilled and pumped to each zone

at a much lower pressure.

THE KEY INGREDIENT

� Excellent thermodynamic

properties

� Low Viscosity vs. Glycol

Comparison Between HYCOOL and Propylene Glycol

Above left & right: Comparison between fluid velocity through a 180° bend in pipework (in fluid cooler). Note: HYCOOL remains turbulent throughout the entire bend and fluid velocity stays above 0.87 m/s. Propylene Glycol drops as low as 0.57 m/s and has a much lower average velocity.

Right: Pumping power required to move Glycol vs. HYCOOL

� Low pressure < 3 bar circulating fluids throughout entire refrigeration system: plant area to cold

rooms.

High-Efficiency Hydrocarbon Refrigerants� Frigadon chillers are now available with the R1270 natural refrigerant with ZERO GWP

� Use of this refrigerant can increase compressor Coefficient of Performance (COP) by 10%

� Requires a smaller charge in the refrigeration circuit

Up to 28’-10” (8.8m) long

BLOW THROUGH COILS FOR CA

Room Coil Selection

SIZING FLUID COOLERS

� Manageable coil temperature

� Low TD across coil

� Wide coils with smaller fans

� Minimize short-circuiting using

baffles around coils

� High Air-Flow Per Bushel

2012 Stainless Steel Edition

CONTROL PANELS� Energy Management System can control refrigeration, lighting, ventilation, and more.

� Demand-limiting by disabling chiller circuits and limiting rooms cooling.

� Intelligent refrigeration control to minimize energy use while emphasizing product quality.

� Real-time Energy Data identifies voltage, current, power, and demand instantly, rather than waiting for the

electric bill to come. Identify power-saving strategies instantly.

� Combined with chillers, KILOWATCH allows new efficient methods of cooling and defrosting

KILOWATCH™ Energy Management System

� Once pulldown is finished, fans no longer run 100% of the time

� Fans run 100% during cooling, then shut down.

� <50% of fans start periodically to “stir” the air

� DYNAMIC STIRRING uses temperature probes throughout the room to identify

temperature differences from areas in the room.

� Color touchscreen – Easy-to-use interface

� REALTIME Energy Usage Data

� Ethernet connectivity – control anywhere in the world

from a Mac, PC or Smartphone

� Daily email status reports with all O2/CO2

� Alarm notifications to smartphone

� Export-Certified Temperature Logging Built-in
