The trainer was designed for heating and plumbing trainees.
A three-way mixing valve in a heating system controls the circulation and feed flow temperature of the water flowing in the heating system. A pump circulates the water in the pipe system. The differential pressure across the pipe system is limited using a relief valve. Bimetallic thermometers indicate the temperatures at all relevant points in the heating circuit.
Learning Objectives / Experiments
- Function and operating behaviour of a three-way
mixing valve - Effect of mixing ratio on feed flow or circulating
flow temperature - Effect of mixer setting on the flow rate
In conjunction with other training panels in the HL 100 series, it is possible to set-up a complete heating system.
