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.
