AK-CC55 Water Loop

Introduction

Application
Refrigeration appliance control for semi plug-in cabinets with a water cooled condenser.
Advantages:
• Broad application coverage for single compressor, dual compressor, variable speed compressor and variable speed
brine pump
• Quick set-up with predefined settings
• Easy configuration and service using a mobile app with Bluetooth
• Robust and precise temperature control via variable speed control of compressor or brine pump
• Oil return management ensuring a long lifetime of the variable speed compressor
• Safety monitoring of high condenser brine inlet temperature
• Option for second condenser outlet brine temperature
• Safety monitoring of compressor and/or variable speed drive
Principle
The temperature in the appliance is registered by one or two temperature sensors located in the air flow before the
evaporator (S3) or after the evaporator (S4) respectively. A setting for thermostat, alarm thermostat and display
reading determines the influence the two sensor values should have for each individual function.
The temperature of the evaporator is registered with the S5 sensor which can be used as a defrosting sensor.
On the condenser side, an S7 sensor is to be mounted at the brine inlet temperature and optionally an S8 sensor can
be mounted at the brine outlet.
The outputs will be configured based on the selected application and for some applications some of the digital
outputs can be user defined.
Application coverage
The AK-CC55 Water Loop controller has a broad application coverage and supports the following main applications:
