How is refrigerant number calculated?

Divide the quantity of refrigerant that the heat pump moves by the time it takes to move it. If it pumps 3.6 kilograms of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilograms per second. Divide the answer to step 1 by the answer to step 2: 51.2 / 0.36 = 142.2 kilojoules per kilogram.

Do technicians who already have a 609 Certification need to be re-certified? If a technician was certified anytime since 1991, there is no required re-certification. Their certification is good for life.

How do you calculate refrigerant formula?

  1. m – 1 = 0 ⇒ m = 1 ⇒ 1 → Carbon atoms.
  2. n + 1 = 2 ⇒ n = 1 ⇒ 1 → Hydrogen atoms.
  3. p = 2 ⇒ 2 → Florine atom. Now,
  4. (n + p + q) = (2m + 2) (1 + 2 + q) = (2 × 1) + 2.
  5. q = 1 ⇒ 1 → Chlorine atoms. ∴ Chemical formula ⇒ CmHnFpClq ⇒ CHClF2
