Chilled water return is the water leaving the AHUs/FCUs and entering the chiller. The normal chiller evaporator approach is below 1C (1.8F) for new chillers. Hence, if the chilled water supply temperature is 6.7C (44F), the evaporating refrigerant temperature is around 6C (42.8F). Usually, chillers have built-in refrigerant ...

A few notes: For the voltage, taking the upper limit (for example, using 230V where the range provided is 200–230V) will give you a “worst case” approximation of the heat generated. The phase refers to whether the chiller has a single-phase ...

How Chilled Water Temperature Affects Chiller Performance?

How Chilled Water Temperature Affects Chiller Performance?

Hence, the chiller works hard to produce chilled water. However, if the actual cooling demand is low, the chilled water going into the cooling coil at 6.7C (44F) will not come out at 12.2C (54F) but maybe around 9-10C (48.2-50F). So, the delta T is low and the chilled water return temperature is low.

Jul 21, 2003 So say the 750 ton unit compressor input is .7 kw/ton, since 1 kw is 2545 btu/hr and 1 ton is 12000 btu/hr, heat rejection of the 750 ton chiller is 2545 x.6 + 12000 = 13527 btu/hr per ton of cooling. Now typical condenser water temperature is 85F entering and 95F leaving or 10F temperature rise.
