Abstract:
The thermodynamics properties of R290 and R22 are calculated in this paper by the new cubical equat ion of state. Their theoret ical cool circulation properties are compared under the standardized w orking condit ions of the cont ioneers. A test w as made on subit itut ing R290 for R22 in a KF-22GM air condit ioner. The test results show that R290 and R22 have almost the equal refrigerant capacity w ithent any change of the conditioner and proper amount of ref rigerant. At the same t ime EER is increased.
