| Water temperature 60F (18C), incoming |
1. One refrigeration ton
(T)3.86kw(1.03TR) |
| Refrigerant evaporator temperature -15F
(-26C), |
2. Required Ton (W) |
| Condensing temperature: 95F (35C) |

5. Evaporative temp -25C base |

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 |
