You must provide an experience for a 4-force ventilation system and
a heat pump air conditioning system.
It consists of an auxiliary heating device with heat pump and
humidification, usable with hot and cold water.
The humidification device must have a sprinkler system that allows
air to cross. You can evaluate and compare its performance and you
can adjust the intake / exhaust valve.
The temperature of hot and cold water can be adjusted by the user.
The complete equipment should be designed to check the operation
from the outside, and the temperature inside is adjustable.
The complete equipment must have an automatic control system, due
to the temperature and organic humidity.
The sequence panel should consist of the automatic control of the
graphic device, and should give an experience and train in the
control of temperature, pressure and humidity adjustment,
connecting the circuits to the power supply.
You should be able to protect the overload and operate the pressure
switch, alarm bell and an indicator light, while problems with the
thermostat occur.
You must control the power (ON / OFF), the monitor, and the data
stored in the computer of the electrical control panel through item
1. It must have insertion and simulation of faults, User manual in
Spanish with theory and practices for instructor and student
