Berdasarkan pengujian didapatkan bahwa temperatur Freezing point -117. 1. 8° Celsius or 163. This colorless gas is better known as HCFC-22, or R-22, or CHClF 2. Impurities in a liquid, such as salt in water, typically lower its freezing point, a phenomenon known as freezing point depression. One is that at higher pressures, the air will have a higher heat capacity per unit volume than at lower pressures, and so flowing high-pressure cold The low pressure side carries R22 gas while the high pressure line carries R22 in a liquid state. 28°F (−107. 4 degrees Fahrenheit). However, this material has been shown in test to be combustible at pressure Boiling Point -40. 5° Celsius or -55.
