Re: [EnergyPlus_Support] "Heat Absorption" in Water to Water HP
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!

Water to water HP - Geothermal water loop removes the condenser heat rejected in summer. This heat is rejected to ground. In winter the water loop absorbs heat from ground and air stream gets heated in heat pump. How much of heat absorbed is given by HP unit selection and varies between unit manufacturers.
Let me know if this helps.

Hi,
In the document "WaterWater_PE_Heating.xls" (available on the helpdesk) can anyone shed a little light on what "heat absorption" (column G) means?
Thanks,
Karen
