1.1 Description
The air handling units (AHU) contain various programmable application controls providing
the user with the widest range of solutions and combinations which can be modified
according to construction requirements, including the destination in which the plant subject is
installed. The possible configurations vary from the simple use of one coil (utilized for
seasonal heating and cooling) to the most complete solution which includes up to three coils
(for preheating, cooling and dehumidifying, and post-heating) plus a dehumidifier,
recuperator, free-cooling function, shutter controls and the fan pickup and delivery controls.
The AHU are widely configurable with built in sectional components to satisfy any user
installation requirement. The primary objective for each solution is to ensure the well being
of the environment, including air quality control and thermoigometric well being.
The optimal summer temperature is between 24-26°C and 40-60%UR; in winter between 18-
22°C
40-60%UR.
This application manages AHU with a single coil which is utlilized for heating during the
winter and cooling during the summer. Environmental conditions are controlled from the
central thermal and are reliant on the pre-selection of hot and cold fluids sent by the coil.
The various control functions include:
- Single coil for cooling/heating management
- Manage up to 3 coils (heating, cooling, post-heating)
- Manage up to 3 stages of resistance for the post-heating
- Controlling humidifier - On/Off and modulating
- Controlling dehumidifier
- Controlling external air shutters for free-cooling and free-heating in temperature
- Controlling external air shutters for free-cooling and free-heating heat exchanger
- Controlling external air shutters for air quality
- Manage heat recuperation (cross-flow, at single coil, rotating)
- Manage heating and cooling pumps
- Fan Delivery/Pickup Management - On/Off and at inverter
- Variation Set Point from digital input and supervisor and nocturnal time zone
- Changing modes of functionalilty from digital input and supervisor
- Seasonal Operation - Winter/Summer
- Alarm history
- Navigational User interface divided into four main levels (User, Maintenance
Operator, Installation Operator, and Constructor) each level protected by a different
password.
