Re: [EnergyPlus_Support] Re: Refrigeration ?'s
Hi Derek,
Can you please elaborate on that? Are you implying that there is a way to estimate the refrigerant charge in a commercial supermarket from the degree of subcooling, if so, can you please let me the calculations.
Haider.

Wouldn't the refrigerant charge in a refrigeration rack be reflected in
subcooling from the condenser? The idd for air cooled condenser has a field
for subcooling.

It is for education to my customers and the industry etc..! All systems
have a leak rate some larger than others. The customer has no relation to
the costs associated with a leak. With the ability to simulate or model
this is the best method that you cannot intentionally leak refrigerant in
the field to determine the cost associated with a leak. Also, provide how
this affects the case performance in temperature stability that your liquid
quality in no longer there. The EPA guidelines for as they call it trigger
rate for Commercial refrigeration is 35% in a 12 month period.
And for the receiver level I would like view the results of a critical
charge compared to overcharged system and how this affects the system
performance and energy costs.
