standard conditions*
Capacity is rated under
the following standard conditions

|
Water temperature 60F
(18C), incoming |

refrigeration ton (T)3.86kw(1.03TR) |
Refrigerant evaporator
temperature -15F (-26C), |
2. Required Ton (W) |

4. Correction factor

Ambient temperature

5. Evaporative temp

60Hz electrical

temperatures, 50 Hz |
CALCULATION
EXAMPLE |
Electric supply and on
units using expansion valves. |
Required
production ton :5 tons, Supply water temp 15C
Assiuming |
|
So the necessary
freezing capacity is asi follows: |
|
QKIW = T X W X R X S |
|
QKIW = T(i3.86) X
W(5TON) X R(1.15) X S(I.19)=26.I4KIW AT -25C ET |
