ZM6125 Computerized Air Conditioning Trainer Technical Teaching
Equipment Didactic Equipment
I Introduction
This trainer is designed for studying of the thermodynamic
transformations the air undergoes when crossing the various stages
of a modem air conditioning unit that serves a room where
temperature and relative humidity must be checked. Measuring air
temperature and humidity in different points enables to analyze air
cooling, heating, humidification, dehumidification.
Moreover some simulators of room and outdoor temperature and of
room humidity are included to verify the logic of control system in
all the conditions that can occur in an air handling unit. The
equipment is also provided with sensible and latent heat generators
installed in the test room that can be used to vary the thermal
load in the same room and to check the response of the control
system.
The controller includes the functions of calibration and control,
it enables students to energy to enter the points of control
system, such as set points, measurement values, etc… via a PC
(demand), so that any alarm along the circuit can be detected and a
different management of the system can be programmed.
Supply software which can monitor voltage, current, frequency,
power, power factor,
pressure, flow, etc, they can be displayed on PC in real time, and
can print report.
II Training Program
Using the psychrometric chart to study the transformations the air
undergoes in the different sections of and air handing unit, that
is: sensible heating, steam humidification, cooling and
dehumidification.
Assessing the heat balances corresponding to the different sections
of the air handing unit
Analyzing the operation of temperature and humidity controllers for
AHU
Direct and reverse acting proportional control
ON/OFF step control
Dampers temperature control
Checking the behaviour of control system versus thermal loads
Supplied with:
