In delta temperature, the reference is calculated using evaporator pressure Po and Media temperature S3. It is based
on the fact that most evaporators have a good eciency if the SH reference is set to be 0.65 multiplied by
temperature dierence from inlet temperature to evaporating temperature. The temperature dierence is
calculated as follows SH = Delta temp factor * (S3-T0).
T0: temperature corresponding to evaporator pressure Po
S3: Media temperature
