3.5 Principle of operation Combustion System The combustion system is based on a fully modulating forced draft combustion air blower, a negative pressure regulator gas valve and a 100% premix burner. On a call for humidity, the combustion air blower starts and creates a negative pressure across an orifice located at the air inlet. The blower starts for a moment to purge the system, then the hot surface ignitor is activated.
When the water level due to the evaporation process reaches level “B”, the level unit sends a signal to the control system, which opens the double inlet valve and the water tank is filled up. On reaching level “A”, the level unit again sends a signal to the control system and the double inlet valve is closed. If the water level goes below level “C”, the combustion will be interrupted until the water level reaches “C” again.
4 Basic planning 4.1 Selecting the unit The selection of the unit is reflected in the type description: Condair GS 80 C G20 RS 1. Required maximum steam capacity 2. Required combustion gas 3. Combustion air supply 4.1.
Important notes: – The required maximum steam capacity depends on the specific application and the installation. The calculated steam capacity based on the above formulas, the h,x diagram and the condition of the air to be humidified does not consider any steam loss (e.g. due to condensation in the steam hoses and the steam distributors), any heat loss of the unit as well as any absorption or release of humidity of materials located in the room being humidified.
4.2 Selecting the control system The various control systems – System 1: Room humidity control System 1 is suited for air conditioning systems with mainly recirculated air. The humidity sensor is preferably located in the room itself or in the exhaust air duct. A1 B1 B2 B3 PIE PIDI Y humidity sensor ventilation interlock airflow monitor safety humidistat external continuous controller (e.g.
– System 3: Supply air humidity control with continuous output limitation Supply air humidity control (humidity sensor installed in supply air duct) should be used only where room humidity control is impracticable for technical reasons. Such systems always require a PI-controller. The humidity sensor (A1) is located in the supply air duct after the steam distribution pipe. The humidity sensor (A2) for the continuous output limitation is located in the supply air duct before the steam distribution pipe.
Control/input signals The Condair GS is regulated via the internal PID controller or an external continuous controller (e.g. PI controller). Important! For the control systems 2 and 3 the external controller must be equipped with two control signal inputs. The Condair GS processes the following control signals: – – – – – – – – 0 ... 10 VDC 2 ... 10 VDC 0 ... 10 mADC 2 ... 10 mADC 0 ... 20 mADC 4 ... 20 mADC 0 ... 5 VDC 1 ... 5 VDC Further information is provided in Chapter 5.9.
4.4.2 Accessory details Steam distribution pipes The steam distribution pipes are selected on the basis of the duct width (for horizontal installation) or the duct height (for vertical installation) and the capacity of the steam humidifier. Important! Always select the longest possible steam distribution pipe (optimum humidification distance).
