More and more often, the refrigeration systems are associated with energy recovery systems. Through special heat exchangers, we can recover heat from overheated compressors, all or part of the heat of condensation and the oil heat. Depending on the temperature levels, this heat is used for various purposes. When the temperature level of the recovered energy is not sufficient, it is possible to increase it through the use of heat pumps. Only through a comprehensive analysis by skilled technicians, efficient solutions can be developed and provided to meet the real needs of the contemporary refrigeration / heat.
