Abstract

Refrigerating apparatus comprising two spaces that vary continuously in volume with an essentially constant relative phase difference, one having a lower temperature and the other having a higher temperature, said spaces being in communication with each other through a freezer, a regenerator and a cooler and containing a gas of invariable chemical composition that is subjected to a closed thermodynamic cyclic process in which it is invariably in the same physical state characterized because when the recorder is in normal use the regenerator has a ** (see formula) * * where f is a constant and exceeds 0 08 and preferably exceeds 0 20 and p average of at least 7 atmospheres and where: Cr is the thermal capacity per c.c. In calories-grams/c.c..ºc of the regenerator at a temperature that is the arithmetic mean of the temperatures of the space at a lower temperature and of the space at a higher temperature both in absolute degrees. Fmedia is the average pressure in kgrs/cm2 of the gas with respect to time. B1 is the average volume in c.c. With respect to the time of the volume in which the thermodynamic cyclic process takes place. B2 is the mean total volume in c.c. With respect to the time of the volume in which the thermodynamic cyclic process takes place, said average total volume being reduced to the temperature. Tw is the absolute temperature in absolute degrees of the gas at the point at which this gas enters the lower temperature space and K is the relation between the specific heat at a constant pressure and the specific heat at a constant volume of the gas at the temperature = which is the arithmetic mean of the temperatures of the lowest temperature space and the highest temperature space.
