BASIC TRICOIL® CONTROL STRATEGIES
USA patent numbers
5,181,552, 5,228,302 5,337,577. Other USA and foreign patents pending.
Simple Control: Without Reheat Coil By-pass Valve
| Cooling Mode: | First Step of Cooling: Operate TRICOIL® pump and modulate chilled water valve (or cycle stages of DX cooling) to maintain room temperature. |
| Second Step Cooling: Stop pump. Latent Capacity is transferred to sensible. | |
| Heating Mode: | Operate pump. Modulate heating hot water valve to maintain room temperature. |
| Dehumidification Mode: | Operate pump and operate cooling at 100% of cooling capacity (first step). Modulate the heating hot water valve to maintain the desired room temperature. |
Advanced
Control: Modulating Control of the Reheat Coil Bypass Valve
| Cooling Mode: | First Step is identical to simple mode. |
| Second Step of Cooling: Modulate reheat coil by-pass valve to maintain the room air temperature. | |
| Heating Mode: | Operate pump. Position reheat coil by-pass to the by-pass position. Modulate heating hot water valve to maintain room temperature. The reheat coil by-pass valve can be positioned for full by-pass so that only the precooling coil is used for the heating and/or freeze protection duty. |
| Dehumidification Mode: | Operate pump and operate cooling at 100% of cooling capacity (first step). Position reheat coil by-pass valve for 100% flow through the reheat coil. Modulate the heating hot water valve to maintain the desired room temperature. |
Additional reset schedules and energy management techniques can be used.
