2019-12-03 19:22:42 -0500 | marked best answer | Question for the Energyplus example file:RoomAirflowNetwork.idf Hello everyone I want to ask a question about the example file: RoomAirflowNetwork.idf. Can this RoomAirflowNetwork be calculated using the ideal load system? I modified this file and changed the original air-conditioning system: ZoneHVAC: PackagedTerminalAirConditioner to ZoneHVAC: IdealLoadsAirSystem. But after the modification, the following error was displayed. I have two questions: 1) Can't RoomAirflowNetwork be used in an IdealLoadsAirSystem? 2) How should I fix this problem? thank you for your help! |

2019-09-18 22:23:03 -0500 | marked best answer | simulation load by using airflow network and ideal load air system I want to simulate the load in different areas of the high-large space (high-speed rail station) under natural ventilation (opening door ventilation). Due to the wind infiltration at the entrance to the high space, the wind speed at the entrance is within 0-3 m3/s. In order to simulate the wind speed of each area, I divided the vertical and horizontal directions of the high space into multi-zone and established an inter window(simple opening and horizontal opening) between the zone and the zone. Can the Airflow network simulate the load of each space relatively accurately?can I ignore the role of air momentum? But at the moment my simulation does not seem to be successful, the load is very large in the outer ring (especially at the air inlet), but the load inside is very small, and the gap between the outer ring and the outer ring is very large. The figure below is the data of the load of zones. Another problem is that the temperature in the room is uniform at the same time without air conditioning. Why is the load gap of each zone very large and the indoor temperature (without ideal air system) is very uniform? The figure below is the data of the temperature of zones at the same time(13:00 design day). |

2019-09-09 07:10:38 -0500 | marked best answer | What is the best practice to model an large space in EnergyPlus by using Multi-zone method? I want to get the energy and temperature in different areas of the big space(without using CFD). However I still don't have a clear idea what is the best way of modeling it. I am looking for recommendations on: 1)Preparing geometry: Should we split the large zone into small mult-zones? Is that even make sense considering the EnergyPlus will transfer the radiation as diffuse radiation between the zones? Is natural ventilation simulated correctly? I simulated the load in different areas.The results of my simulation seem to be untrue.The load on the inter-zones is significantly smaller than the outer zones, and the gap is large, which seems strange. |
