Hiron benefits from iJF’s VCC management

CHINA: The adoption of Carel’s iJF controllers are said to have achieved significant energy savings for Chinese food service equipment manufacturer Hiron Commercial Cold Chain Co.

Carel’s iJF solution for variable capacity compressors has been integrated into Hiron’s new chest freezer, a new generation of display cases using R290 refrigerant.

Based in Qingdao, Hiron is a leading player in the professional commercial refrigeration cabinet market, boasting a portfolio of over 100 products.

With the integration of variable speed compressors, the use of R290 refrigerant and an advanced PID regulator, Hiron’s new chest freezer can offer numerous advantages, including optimised maintenance management, optimal food preservation due to temperature stabilisation, while reducing noise and vibrations. 

Hiron is said to have chosen the IJ, with its VCC serial port, as the control solution, due to its energy performance and compliance with flammable refrigerants. 

Thanks to iJF, temperature fluctuations are minimised (below 2°C), and compared to the use of fixed-speed compressors, VCC technology has achieved a 25% reduction in consumption.

Serial mode management of VCC technology involves the controller sending the speed variation request to the inverter via a serial communication protocol, based on cooling demand. Communication is bidirectional – the controller sending the speed control signal and receives related feedback, such as alarms.
