Walk-In Cooler Box Load Parameters

1. 95°F ambient air temperature surrounding box

2. 4" styrene (R=16.7, K=.24) walls/ceiling, 6" concrete slab floor

3. Average product load with 5°F pulldown in 24 hours

4. BTUH load based on 16-18 hour compressor run time for 35°F box (timer recommended) +20 hrs. For 30°F box

5. See Table C for adjustment to box load for glass doors

6. For 80°F ambient temperature. Surrounding box deduct 12%

7. For 4" Urethane walls + ceiling, 6" concrete slab floor deduct 12%

8. For 10' ceiling height add 10%

9. For additional BTUH load for product cooling see Table A

Walk-In Freezer Box Load Parameters

1. 95°F ambient air temperature surrounding box

2. 4" urethane (R=25, K=.16) walls, ceiling + floor

3. Average product load with 10°F pulldown in 24 hours

4. BTUH load based on 18 hour compressor run time

5. See Table C for adjustment to box load for glass doors

6. For 80°F ambient temp. Surrounding box deduct 12%

7. For 20 hour compressor run time (light frost load) in lieu of 18 hour run time, deduct 11%

8. For 10' ceiling height add 10%

9. For additional BTUH load for product cooling see Table D

Table A

For product pulldown greater than 10 degrees, divide pulldown temperature by 10. Multiply this number by the BTUH shown on Table A, then add to box load.

Table D

Freezing loads based on product entering at 40°F maximum. For a specific pulldown time, the product load BTU/hr may be adjusted by multiplying the above loads by 24 and dividing by the specified pulldown time in hours. To adjust for 0°F freezer temperature, multiply the above loads by 0.97, and for -20°F freezer, multiply by 1.04
