I dont have access to ISO 13256-1. Need someone who has access to answer the following (re: open loop well water system):
1. Does it specify a pumping penalty be included in the EER and COP calculations?
2. Is pumping penalty calcualated the same as in ARI-325?
3. (If no pumping penalty included in EER/COP or same as ARI-325, then ignore this question) Can you provide the lookup table and/or equations required to calculate pumping penalty?
I want to perform a calculation to adjust manufacturer provided EER and COP of Geothermal units to use a pumping penalty that I will actually experience in a residential open loop geothermal installation (I have an existing well. And I know the actual pumping power).
I have done this calculation with ARI-325 and rejected some older units for sale on ebay because in my case, the pumping penalty makes the effective EER no better than a high efficency air unit. EER and COP data on newer units are given per ISO 13256-1, so i need to know what pumping penalty is already included so i can back it out and include mine.
