[Equest-users] Weird request to everyone

Dear All,

Its a very weird request to all of you in your busy schedule. As in my
earlier thread for modelling of Water loop heat pump in equest and query
was regarding the low heating consumption. I am still doubtful about the
heating consumption in the Proposed case in which system is water loop heat
pump with supplemental boiler and cooling tower to maintain the loop
temperature.

As the Proposed case is water loop heat pump with gas boiler, the baseline
case system type will be System Type 1 (PTAC with fossil fuel boiler). The
simulation results for baseline and proposed case shows around 97% energy
savings in Heating end-use. The climate type as per ASHRAE is 4A
(Washington DC). I have checked hourly loop temperature profile, boiler and
cooling tower operation hours and seems fine. The boiler is working in
winter months but with very little energy consumption.

Here, I am attaching the proposed case model with weather file and hoping
if anyone can look into the model. I will appreciate any suggestions to
improve the model.

Thank you.

Regards,

Mayank Bhatnagar
