Scroll chiller controller

Scroll chiller controller – v.chill Scroll series is a specialized solution for managing compression chillers equipped with scroll compressors up to two circuits and three compressors in each circuit. It is also able to manage compressors by rotation.  The special advantage of this product compared to the uChiller series is its application in medium-capacity chillers.

The special feature of this product is the dynamic control of the working point of the compressor within its working range (Envelope). This operation is based on the constant reading of the suction and discharge pressure, the result of which is to guarantee the correct operation of the compressors and increase efficiency.

In the scroll chiller controller kit, the display screen will help the user control the chiller.

All required parameters can be seen on this display. Using a set of menus grouped according to system components makes it easy to access device settings and manage its parameters.

Advantages of using Carel chiller controller for scroll chiller

 

Among the benefits of v.ChillScroll, the following can be mentioned:

 

• Scroll chiller control up to two circuits (each circuit up to three compressors)
• Ability to rotate compressors based on FIFO and operating hours
• Control of compressors based on the working area (Envelope)
• Condenser fan capacity control through fan speed control or on/off up to one fan group in each circuit (using SSR relay)
• Ability to use water condenser
• The ability to set two startup and operation setpoints for the condenser
• Evaporator pump control including Standing by the pump. with the ability to set the time delay between the pump and the compressor start
• Gradual increase of cooling capacity at start time
• The ability to automatically change the set point based on the outside temperature or command through the supervisor
• Defrost control and 4way valve (in heat pump mode)
• Ability to control free cooling
• Ability to connect to BMS network and Vida cloud service kit through RS485\ModbusRTU protocolFor more information about the scroll chiller controller, you can refer to the link below:https://www.carel.com/c.pco-sistema
