High temperature heat pumps for seasonal thermal energy storage and district heating systems.

Number: pap. n. 259

Author(s) : HEWITT N., HUANG M., RAMIREZ M.

Summary

R245fa was selected to operate with a the working fluid for a seasonal thermal energy storage (STES) heat pump whose role was to upgrade the temperature of the heat when it was insufficient to heat a hospital administration building near Warsaw, Poland. The selection of R245fa was based on a series of theoretical and laboratory tests indicating its superior performance when operating with the higher evaporator conditions encountered when working with a STES. High coefficients of performance are presented and the challenges of operating a heat pump with a STES are discussed.
