INFLUENCE OF CONTROLLER TYPES IN HVAC SPLIT SYSTEMS ON ZONE COMFORT AND ENERGY CONSUMPTION

摘要

This article introduces the modelling of the split system (room air conditioner) with a continuous action controller for a building energy simulation. This model shows a way to calculate the energy consumption, the sensible and latent cooling capacity of the split system at part load operation matching the sensible and latent cooling zone loads. As a result, the zone air states can be exactly determined. The model of the split system with a two-pointcontroller has already been developed and verified (Neymark and Judkoff 1998; Neymark and Judkoff 2000; Knabe and Le 2000a). Results of the simulation show an impact of the two controller types on both the room comfort (temperature and humidity) and the energy consumption.
