The economizer will be deactivated if one of the following conditions apply:
Circuit in Off state
Circuit Pressure Ratio < Econ Act PR – 0.3
Discharge Superheat < 17°C (This condition is ignored with the EWAD TZ B)
5.7 Liquid Injection Control
Liquid injection will be activated when the discharge temperature rises above a safety limit
temperature to avoid compressor components overheating.
Liquid injection will be turned off when the discharge temperature decreases below the activation
setpoint by a differential of 5°C.
5.8 Variable Volume Ratio Control
Compressor Volume Ratio is controlled through VR slides in the compressor. These slides adapt
discharge port geometry to achieve optimum compressor efficiency according to chiller operating
conditions.
VR slides are moved between two positions, called VR2 (corresponding to a volume ratio 2.0) and
VR3 (corresponding to a volume ratio 3). At compressor off, no slide valve is excited.
At startup, slide is positioned to VR3.
In running condition the selection between VR2 and VR3 will be done automatically to
maximize compressor efficiency.
