PRODUCT
HL 105 Three-Way Mixing Valve Training Panel
Education / GUNT Hamburg / Thermal Engineering and HVAC / Heating and Ventilation in Buildings /
description

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.
