Description

ET 182 Secondary Controllers In Refrigeration Systems Didactic Equipment Vocational Education Equipment Refrigeration Training Equipment

Demonstration of the principle of operation of the various secondary controllers in the refrigeration circuit
Features
- familiarisation with common secondary controllers in refrigeration systems
- secondary controllers can be decommissioned individually for fault finding
- refrigeration and freezing stage with cooling load
- different secondary controllers at the water-cooled condenser
Learning objectives/experiments
- properties and application options of different secondary controllers
-- evaporation pressure controller (KVP)
-- start-up controller (compressor intake control; KVL)
-- capacity controller (control of the compressor delivery capacity; KVC)
-- condensation pressure controller (WVFX, KVR)
-- receiver pressure controller (KVD with NRD)
- adjustment of optimum operating points
- fault finding in secondary controllers
