[en] HVAC&R components operate most of the time in part load conditions for which little data are available from manufacturers. This makes performance prediction difficult. Approaches and problems are presented for simulating the performance of HVAC&R components under part load conditions and under consideration of dynamic effects such as cycling. The seminar motivates a discussion about HVAC&R component modeling for part load and dynamic conditions and it dscusses what additional data are required from manufacturers to assess the performance at these conditions.
