1.Overview
DLZL-AH01 Thermodynamics Lab Equipment Heat Transfer Lab Equipment studying the technology of heat exchange and heat exchanger. The training equipment is built around the profile sheet metal workbench, which contains a control panel for installing components. The ther Mal trainer teaching equipment includes a service unit , which provides necessary facilities and measuring instruments to test four types of heat exchangers: steel radiators for heating, fan coil exchangers for heating and cooling, tube-in-tube (double-tube) exchangers and shell-and-tube heat exchangers.
2.Configuration

3.Training contents
The trainer shall study:
-Water/air radiator type for heating.
-(Water/air + fan ) fan-coil exchanger for heating and cooling .
-Water/water double tube exchanger , reversed flow.
-Water / water shell and tube exchanger type .
-Measurement of the temperatures of the water and air at different points of the exchanger.
-Measurement of the temperatures of the water and air before and after the exchanger.
-Determination of the capacity of heat exchanged.
-Measuring the pressure drop of hot water before and after the exchanger.
-Measuring the pressure drop of cold water before and after the exchanger.
-Comparing types of heat exchangers.
-Measuring the flow of ratio of water and air and determining the best velocity of the water flow and air flow.
