The templates consist This page consists of various template configurations of a CHP combined with a boiler available in the Inspiration library. All the controls feature a combined heat and power unit, with the standard control discussed here.
CHP & Boiler - Parallel
...
Working principle
...
...
The boiler is activated when the flow temperature of the system drops below 73°C , (75-2°C) and deactivated when the flow temperature increases above 77°C(75+2°C). The activation also includes a check for minimal flow rate, if the flow rate through the system is insufficient, the boiler won’t be activated. For instance, if the installation is disabled, the temperatures in the pipes will drop but the boiler won’t be activated because there is no flow through the system. During the activation of the boiler, an isolation valve at the boiler will open.
...
The system can be further optimised by doing sensitivity studies. For instance, a sensitivity study can be done for the size of the storage vessel or the thermal power of the CHP. To change the thermal power, the user should change the power spread found in the hybrid production configuration BC. More information about hybrid production configurations can be found in https://hysopt.atlassian.net/wiki/spaces/HRM/pages/3089204289/Hybrid+production+Heating.
The user should lock the nominal thermal power and return temperature of the CHP. If not, the software will assume the propagated power and return temperature from the installation.

CHP & Boiler - Reverse shunt in return
...
Idem as Similar to the template “CHP & Boiler - Parallel”, except for the shunt configuration instead of the parallel configuration. There is also a bypass valve to bypass the boiler when the boiler is deactivated.

CHP & Boiler - Switchable serial in supply - Stirling motor
...
Similar to the template “CHP & Boiler - Switchable serial in supply”, but in this template, a Stirling motor CHP is used. More information about the Stirling motor can be found in CHP (Combined Heat & Power) CHPs. The controls for the Stirling CHP are also more basic than the traditional CHP, it will be activated and deactivated depending on the measured upper or lower temperature in the storage tank.
