   1 1.4 SELECTION EXAMPLE A chiller is required to chill water from 13°C to 7°C, with a cooling capacity of 119 kW. There are also other design conditions: • Ambient air entering the condensing unit 35°C • Fouling factor: 0.044 m2 °C/kW • Altitude: Sea level Taking a quick look at the table, we can…

7. Стр. 8 Selection guide (YLCA/YLHA)

   YLHA SELECTION EXAMPLE A YLHA heat pump operating at a 35°C ambient temperature should chill water from 13°C to 7°C, with a 112 kW cooling capacity. A 110 kW heating capacity is required in 5°C design ambient temperature and a hot water output tem‐ perature of 40°C. The fouling factor is 0.044 m2…

   On design glycol concentration, apply the capacity correcting factors x 1.015 and power x 1.005 (see Correcting factors for other glycol concentrations, see on page 12). Applying these factors to the selection: YLCA ‑120 Capacity = 76.8 x 0.987 x 0.973 x 1.015 = 74.9 kW Comp. power = 28.8 x 0.995 x…
