Using the data about the temperature - pressure phase diagram and the
phase transition entropy at ambient and high pressure, intensive and
extensive barocaloric effects were analyzed in the region of single and
successive order-disorder phase transitions in fluorides and oxyfluorides
with the elpasolites-cryolite structure. It was found that hydrostatic as
well as chemical pressure are the effective tools to change the entropy of
compounds with disordered ionic groups or atoms in structure and to
realize the significant intensive and extensive barocaloric effects
comparable with the values of baro- and magnetocaloric effects,
characteristic formaterials, considered as promising solid refrigerants.
