Product introduction of Danfoss EKC361-EKC315A (084B7086) controller

The evaporator superheat controller and electronic expansion valve are used in refrigeration projects that require precise control of superheat or temperature.
E.g :
• Cold storage (cool fan)
• Processing plant (chiller)
• Air conditioning units

■ Can always optimize the refrigerant charge of the system – even when the system load fluctuates greatly and the different evaporation pressures
■ Energy saving-due to the adaptive control to adjust the evaporator liquid supply, the evaporator's heat exchange efficiency, optimize the system's evaporation pressure, to achieve the purpose of energy saving
■ Accurate temperature control-By coordinating the heat exchange and temperature control functions of the evaporator, the temperature control accuracy of the cooled medium can be ensured
■ The superheat can be adjusted to the optimum, and the temperature of the cooled medium can also be controlled by the temperature control function

Danfoss EKC361-EKC315A (084B7086) controller function introduction

Features
• Superheat adjustment
• temperature control
• MOP function
• Through ON / OFF input, the controller starts and stops control
• Input signal can collect and display the superheat and the temperature of the cooling medium
• If the data exceeds the alarm setting, an alarm signal can be output.
• There is a relay output to control the solenoid valve switch.
• PID parameter adjustment function
• Can output temperature parameters displayed on the controller
system
The superheat control of the evaporator is calculated by the data of a pressure sensor P and a temperature sensor S2 (respectively giving the detection signals of the refrigerant pressure and temperature at the outlet of the evaporator). The following electronic expansion valve is selected as the expansion device:
• ICM
• AKV (AKVA)
ICM is an electric expansion valve, which is controlled by an ICAD motor driver. It is recommended to install a solenoid valve before the ICM valve in the liquid supply pipeline to ensure its shut-off.
The controller can also control TQ series valves.
AKV is a pulse type electronic expansion valve
AKV has the function of a solenoid valve, but it is still recommended to install a solenoid valve before the valve when it is used in the liquid supply line.
The temperature control function is adjusted according to the temperature signal of the S3 temperature sensor installed in the return air of the evaporator. Temperature control is achieved through an ON / OFF temperature controller, which cuts off or opens the system's liquid supply.
