If temperatures below the eChiller’s scope are required which e.g. is common in the commercial refrigeration segment, eChillers can be combined with other processes in cascade arrangements. Due to its operational temperature range, the eChiller is used in the high-temperature stage of the cascade.
efficient energy is currently investigating the implementation of the first eChiller cascade applications, which have already delivered promising results.
Are you interested in sustainable cooling of your commerial refrigeration cabinets or fresh food counters using an eChiller cascade application in combination with a further natural refrigerantas CO2 or propane?
Contact us to discuss the possibilities for a joint project.
In the following, the different interconnection options for eChiller cascades with the respective refrigerants are explained:
The entire condensation heat of the low-temperature stage is dissipated by the eChiller
For the implementation of a partial cascade, a transcritical CO2 process is combined with an eChiller. The eChiller subcools the supercritical CO2 after the gas cooler to increase the cooling capacity.
