Cooling Cycle Construction

RECOMMENDED MODEL SELECTION METHOD

Use parameters of enclosure (The values used are examples.)

(1) Total surface area of enclosure (S)
W 1000 mm x H 2000 mm x d 600 mm
S = 7 m2 (except the bottom)

(2) Estimated total amount of heat produced in the enclosure (P)
P = 500 W

To make the internal temperature setting lower than the maximum ambient temperature.
(1) Maximum ambient temperature (T1)
T1 = 40 °C

(2) Temperature setting inside the enclosure (T2)
T2 = 35 °C

หมายเหตุ : Sheet steel, free standing
- Heat transition coefficient of the enclosure (U)
U = 5 W / (m2.K)
- Difference between (T) the temperature setting inside the enclosure(T1) and maximum ambient temperature (T2)
T = T1 - T2 = 5 °C

The above values are used to obtain the amount of heat transmitted from the outside into the enclosure (P1)
P1 = U x S x T
= 5 x 7 x 5
= 175 W

The minimum cooling output (PT) required for this case
PT = P + P1
= 500 + 175
= 675 W

Select a model whose cooling output in higher than the required cooling output (PT)
