9. Selection Procedure Step 1. Determine cooling load requirements at design conditions. Required load conditions: Required cooling capacity (TC) .............................. 24,000 Btu/h Sensible capacity (SHC) ........................................ 20,200 Btu/h Temperature air entering Outdoor Unit ................. 95°F Temperature air entering Indoor Unit ..................... 80.6 °F DB/66.2°FWB DB — dry bulb temperature WB — wet bulb temperature Step 2. Select unit based on required cooling capacity. Based on Total Cooling Capacity, choose suitable model from the specification table. The model with net cooling capacity of 24,000 Btu/h is selected. The system is HT-C246HLA0. Verify the unit performance at the given conditions in accordance with step 3. Step 3. Determine if system selected satisfies cooling requirements. Enter cooling capacities table on page 30 at high speed and 95°F outdoor entering air temperature with 80.6°FDB/66.2°FWB indoor entering air temperature. Total cooling capacity = 24,000 Btu/h, Sensible capacity=20,200 Btu/h To find capacity at intermediate conditions not in the table ; Interpolation should be used when design conditions are between two numbers that are in the capacity table. Extra-polation is not recommended. If the interconnecting piping length is more than 7.5 m ; Find the capacity(%) at that particular interconnecting piping length from the coefficient of capacity change graph, on page 33. . Multiply coefficient factor with Total Cooling Capacity & Sensible Capacity. Ex: At 30m interconnecting piping length, from coefficient of capacity change graph, coeffienct factor is 0.915.

Total Cooling Capacity =

Capacity (%) x Total Cooling Capacity 91.5x24,000 = = 21,960 Btu/h 100 100

91.5x19,300 Sensible Capacity = Capacity (%) x Sensible Capacity = = 18,483 Btu/h 100 100
