CHAPTER
III : Calculation of Lossnay energy recovery effect
(A) Lossnay model
(B) Temperature exchange efficiency for summer (at 1000m
(C) Enthalpy exchange efficiency on cooling (at 1000m
(D) Lossnay outlet air temperature
= (G) – ((G) - (I)) x (B) = 33
(E) Lossnay outlet air enthalpy
= (H) – ((H) – (J)) x (C) = 84.6 - (84.6 – 52.8) x 0.71
(F) Energy recovered by Lossnay
=((H) – (E)) x ρ x Q

Selection of Dx-coil unit and outdoor unit
STEP2.
Dx-coil unit should be selected by connected Lossnay model shown in the table below.
Besides, outdoor unit is naturally selected by required temperature control, RA or SA.
