SYSTEMES INNOVANTS

The Computer Controlled Air Conditioning Laboratory Unit, "TAAC", main objective is to introduce the student in the complex world of the air conditioning installations, as well as to study and determine the optimal parameters for the unit operation in function of the environmental requirements (humidity, heat, temperature and refrigeration, etc.).

Voir description générale

Description Générale

The Computer Controlled Air Conditioning Laboratory Unit, "TAAC", has been designed to study the change of the air conditions and the refrigeration circuit.

The unit consists of a testing tunnel made of stainless steel, in which there have installed two windows. Inside of the tunnel there is an axial fan (computer controlled) and two heating elements (computer controlled), one situated at the evaporator inlet and other situated at the evaporator outlet.

The unit has a flow sensor and four hygrometers situated along the tunnel. These hygrometers are formed by two temperature sensors (wet and dry bulb).

Two steam lines inject steam from a steam generator (not included) to the tunnel to modify the air characteristics.

The tunnel includes an evaporator in the middle. It consists of a finned radiator through which a coolant flow circulates. This radiator is placed perpendicular to the air flow generated by the fan.

Coolant flows through a closed circuit. It enters to the compressor (computer controlled) and circulates through a filter (to retain particles of condensate), a flow sensor, an expansion valve, the tunnel evaporator (the coolant absorbs the air heat of the flowing through the evaporator) and a condenser.

Several temperature, pressure and flow sensors and manometers have been strategically located, allowing to study the refrigeration cycle and quantify the evaporation and condensation capacity. In addition, the unit includes a high pressure control to avoid an excess of pressure in the unit.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
