Optimization of hot gas defrosting is complicated issue. As you can see in this article we have more questions than answers. Just a few remarks.
1. I didn't get question about optimal hot gas temperature.
2. I don't see HEVs for hot gas.
3. Defrost energy required is focused on the coil only. No information about parasitic refrigeration load due to blow-by gas.
4. Very important question: When do you initiate a defrosting?
