HFO COMPRESSOR FOR THE PRODUCTION OF HOT WATER

HFO COMPRESSOR FOR THE PRODUCTION OF HOT WATER

01.12.2014

A prototype system has been developed and tested using HFO-1234ze. It is able both to raise the temperature of food products rapidly to close to 100 °C, and to immediately cool them down to 2 °C using chilled water.

Two variable speed compressors are operated independently on the same circuit in two systems, the first one heating water from 3 to 53 °C, and the second one from 48 to 100 °C

It is normal in the food industry to recover exhaust heat from refrigeration compressors to provide hot water, and such a system could be installed in other food processing facilities.

Besides its obvious environmental qualities, HFO-1234ze was selected because of its thermodynamic properties, since ammonia (R-717) cannot reach temperatures above 80 °C, and CO2 is not energy efficient at high temperatures.
