Abstract
A method for removing heat from a refrigeration load in a cyclically operating Gifford-McMahon refrigeration apparatus, with which in each cycle a compressed cooling gas from a high-pressure inlet is brought into heat contact with a regenerator cooled during the previous cycle and thereby cooled, the cooling gas is subsequently conveyed to a storage volume via the refrigeration load, the cooling gas is then expanded after closure of the high-pressure inlet by opening a low-pressure outlet and thereby cooled, and the cooling gas is partially conveyed by means of a displacer piston from the storage volume to the low-pressure outlet via the refrigeration load and the regenerator, refrigeration capacity hereby being transferred to the refrigeration load and the regenerator hereby being cooled.
