Defrost cycles in cold stores

The basic problem is not a new one. Applications that have evaporation temperatures of 0°C or below regularly experience ice build-up on the surface of the air cooler’s fins. The heat transfer is thus reduced, resulting in a decrease of the air cooler’s efficiency. The build-up of ice is caused by the dehumidification of the refrigerator room, when…

Energy Optimisation in Industrial Refrigeration Systems

New measurement method solves the problem of a high pressure drop in risers and wet suction lines in refrigeration systems In low-temperature ammonia systems the pressure loss in the return line to the compressor is significant for the capacity of the compressor and the efficiency of the system. The desigh of the return line whether wet or dry…

HB Products Gas Quality Sensor in a Cold Store in Melbourne, Australia

  Low Charge Ammonia System Controlled by Gas Quality Sensors It`s now possible to design Low Charge dry expansion systems, more energy efficient than conventional flooded and pump circulation systems. The potential for the application of this new technology is very large, and used with the latest energy efficient evaporators and compressors it can achieve energy savings of…

Gas quality sensor increases energy efficiency with 30%

  Experience gathered from 4 ammonia systems set up in Australia shows that systems with gas quality measurement/control are more energy efficient than conventional flooded and pump circulations systems. It is now possible to control and regulate an evaporator in a refrigeration system using a sensor mounted on the evaporator outlet, as an alternative to traditional superheat measurement/control based…

Defrost sensor

De-frost sensor results in energy savings in a range of 5..15 %. HBDF is a simple solution for energy-optimal automatic defrosting of evaporators. It results in energy savings of 5-15 %, thus quickly recouping its cost. Read more abot the defrost sensor.
