Parameters for the heat recovery heat pump in energy transfer station
Information
Parameters that describe the performance of the heat pump, and design quantities such as temperatures and design mass flow rates of the heat pump.
The performance table in datHea are used to describe the
change in performance for off-design conditions.
The heat pump's heating capacity is, however,
determined solely by the parameters
QHeaDes_flow_nominal for the desired heating capacity at the
leaving condenser temperature THeaConLvg_nominal and the
leaving evaporator temperature THeaEvaLvg_nominal.
The performance table for the evaporator heat flow rate and the electricity
consumption are then scaled up or down to meet this capacity.
This scaled capacity is stored in datHeaSca, and used during the simulation.
The record also computes the cooling capacity at the design conditions
TCooConLvg_nominal and TCooEvaLvg_nominal,
and stores it in the parameter QCooAct_flow_nominal.
This can then be compared to the desired cooling capacity
QCooDes_flow_nominal.
The model also computes the COP for heating and for cooling at the
design temperatures THeaConLvg_nominal and THeaEvaLvg_nominal
for heating and
TCooConLvg_nominal and TCooEvaLvg_nominal
for cooling. These are for reporting only and not used in the heat pump model.
