Case/room controller (EEV) Type AK-CC55

For exible control of refrigeration appliances and cold storage rooms.

AK-CC55 is a complete refrigeration appliance control with great exibility to adapt to refrigeration appliances and cold storage rooms.

AK-CC55 Compact, Single Coil, and Multi Coil controllers are optimized to control refrigerated display cases or cold rooms with electronic expansion valve type AKV. In addition to the valve output, the controllers hold a pressure input, temperature sensor inputs, digital inputs as well as an analogue output and relay outputs that can be applied to numerous functionalities in a refrigeration system.

The temperature in the appliance is registered by temperature sensors in the air ow before the evaporator and after the evaporator. A setting for thermostat, alarm thermostat and display reading determines the inuence the sensor values should have for the control functions. Additional sensors can be used for registration and alarming of the temperature near the food items, registration of the temperature of the evaporator and also as defrosting sensors.

Case/room controller (EEV), type AK-CC55

Features

• Universal controller for several dierent refrigeration appliances

• Quick set-up with predened settings

• Easy conguration and service using a mobile app with Bluetooth

• Energy optimization of the whole refrigeration appliance

• Adaptive Minimum Stable Superheat (MSS) control is performed with lowest possible superheat

Portfolio overview

The AK-CC55 portfolio contains four controllers with dierent functionalities and application settings, as outlined in the table.

For a complete breakdown on the individual controller and their functions, refer to the respective User Guide for the controllers.

Table 1: AK-CC55 Portfolio

Product categories mentioned in the table are outlined in the next sections.

External display

There are three versions available with dierent functions.

• AK-UI55 Info: Temperature display.

• AK-UI55 Set: Temperature display with control buttons on the front.

• AK-UI55 Bluetooth: Temperature display with Bluetooth communication, for use with AK-CC Connect App.

Products used in AK-CC55 systems

KoolProg

The KoolProg software enables you to perform online conguration and monitoring of AK-CC55 controllers as well as oine conguration of setting les, which can be shared with the AK-CC55 Connect APP for mobile devices. Furthermore, it allows you to make production line programming of controllers in an ecient way and to update controller rmware.

KoolProg must be connected to the display port of an AK-CC55 controller via MMIMYK gateway:

Electric expansion valve, type AKV 10P, AKV 10PS

Figure 6: Type AKV 10P, AKV 10PS

AKV 10P and AKV10PS are electric operated expansion valves designed for refrigerating plants.

The AKV 10P and AKV 10PS valves are normally controlled by a controller from Danfoss range of ADAP- KOOL® controllers, that ensures a precise liquid injection into evaporators.

The AKV 10P and AKV 10PS valves are supplied as a part program, as follows:

• Separate valve

• Separate coil with terminal box, DIN plug or cable

• Spare parts in the form upper part, orice and lter

Case/room controller (EEV), type AK-CC55

The orice assembly is replaceable. The AKV 10P and AKV 10PS valves cover a wide capacity range.

Pressure transmitter, type AKS 32R and AKS 2050

Figure 7: Type AKS 32R and AKS 2050

AKS 32R is a ratiometric pressure transmitter that converts the measured pressure to a linear output signal. The output signal is relative to the supply voltage meaning that the min. pressure output will be 10% of the actual supply voltage and the max. pressure output will be 90% of the actual supply voltage.

At a supply voltage of 5 V, the output signal is:

• 0.5 V at min pressure range

• 4.5 V at max. pressure range

The robust design and the ratiometric output signal makes the transmitter suitable for systems together with ratiometric A/D converters within a number of elds:

• A/C systems

• Refrigeration plant

• CO2 plant

• Process control

• Laboratories

Pressure transmitter, type DST P110

Figure 8: Type DST P110

The Danfoss DST P110 series pressure transmitter is designed for demanding refrigeration, air conditioning and industrial cooling applications, such as:

• Chillers

• Transport refrigeration

• Commercial refrigeration

• Variable speed HVAC

• Heat pumps

• Variable refrigerant ow (VRF)

Drawn from over 30 years of experience with MEMS pressure sensing, the DST P110 oers outstanding performance in a compact and durable stainless-steel package.

Case/room controller (EEV), type AK-CC55

Running a powerful ARM-based microcontroller, the DST P110 oers diagnostic features and scalable performance features at a competitive price.

Colour coded temperature sensors, type AKS 11

Figure 9: Type AKS 11

Pt 1000 temperature sensor.

The sensor can be used for temperature monitoring and logging in conjunction with Danfoss controllers in the following areas:

• Refrigeration

• Air conditioning

• Heating

The sensor comes adjusted and complies with the requirements to tolerance in EN 60751, class B.

AKS 32R info

The signal from one pressure transmitter can be received by up to 10 controllers. There must not be a signicant pressure drop from the pressure transmitter's position in the suction line to the individual evaporators. Other products can be part of the system as well, depending on application scope.
