Calculate Coefficient of ferformance (COP) pf an ideal pulse tube refrigerator by using thermodynamics calculator online.
The pulse tube refrigerator (PTR) or pulse tube cryocooler is a developing technology that emerged largely in the early 1980s with a series of other innovations in the broader field of thermoacoustics. In contrast with other cryocoolers (e.g. Stirling cryocooler and GM-refrigerators), this cryocooler can be made without moving parts in the low temperature part of the device, making the cooler suitable for a wide variety of applications.
Formula:
where,
ΞΎPTR = COP (Coefficient of Performance) for the non perfectly reversible cooler
TL = Low temperature
TH = High temperature
PTR = pulse tube refrigerator
