61  Quantity of heat and cooling generated

Quantity of heat
 (1) The quantity of heat generated by a CHP plant during an NGER reporting year, in gigajoules, is worked out using the formula (equation 28):
where:
QH,p means the quantity of heat generated by CHP plant p, in gigajoules.
mSO means the mass of the steam produced by the boiler, in kilograms.
hSO means the enthalpy of the steam produced by the boiler, in kilojoules per kilogram.
mSI means the mass of the boiler feedwater, in kilograms.
hSI means the enthalpy of the boiler feedwater, in kilojoules per kilogram.

Quantity of cooling
 (2) The quantity of cooling generated by a CHP plant during an NGER reporting year, in gigajoules, is worked out using the formula (equation 29):
where:
QC,p means the quantity of cooling generated by CHP plant p, in gigajoules.
mWI means the mass of the return water that goes into the absorption chiller of the CHP plant, in kilograms.
hWI means the enthalpy of the return water that goes into the absorption chiller, in kilojoules per kilogram.
mWO means the mass of the cool water outflow from the absorption chiller, in kilograms.
hWO means the enthalpy of the cool water outflow from the absorption chiller, in kilojoules per kilogram.

Enthalpy values
 (3) For the purposes of equations 28 and 29, the enthalpy values used must correspond to the values for the appropriate phase (such as saturated liquid or superheated vapour) for the measured temperature and pressure of the water (or other refrigerant used) in the CHP plant.
