RE: [EnergyPlus_Support] "Heat Absorption" in Water to Water HP





p.s., Cooling capacity will be ~ Power input x EER

That is kind of what I thought it was - usually this is roughly equivalent to the grid energy (usually electricity) used to power the machine.  If you have a 5KW machine, then either the system or surrounding space needs to absorb 5KW.  If the load side absorbs the heat, this is considered part of the total heating capacity of the machine, right?

 

Unfortunately, this is not a number given by the manufacturer of the heat pump I'm currently modeling.  What is a reasonable range for absorption versus reject to the space?

 

I assume that this absorption is absorption into the load water loop??

 

Thanks!

 

Karen
