Hello, In the current version of WUFI Plus v3.2.0.1, I would like to see whether it could handle the Supply or Exhaust Ventilation mode in the static air flow balances without using the airflow mode. The dual directional interzonal ventilation airflow rates seem to be specified between zone (i) and ...

Hello. If we operate WUFI Plus 3.2.01 in Japanese menu, Window parameters can not be updated after selecting an alternative parameter from database. If we switch the menu language into English, it is able to be updated normally. Hope you fix this issue quickly. note: I could not figure it out how to...

We are using Air Flow Model in WUFI Plus V3.1.1.0. It would be highly appreciated if you could tell us how to implement the following conditions in WUFI Plus with certain switches or functions. 1) Specify the arbitral time series of DB & RH for a supply air not equal to the outdoor air. 2) Outpu...

In order to follow up our question, we checked the results on a similar example case with no windows. In the result of heat flows (monthly), the exchange with opaque partitions became gains in summer and losses in winter. However we don't know the precise definition of each elements appeared in the ...

Dear Sirs; In order to apply Plus 3.0.3 for evaluating hygrothermal performances of timber framed detached house, we ran a simple benchmark case.　It consists of a single zone of 6 x 6 x 3 m with windows of 4 x 2 and 4 x 1 m. In the graphical results of heat flow (monthly), the monthly heat flow on t...

Hello. I shortly browsed the WUFI weather file info on Google Earth after downloading the WUFI Weather file.kmz. However the most of German descriptions are not so complicated on the annual statical values, I am wondering iy you could provide the English version of WUFI Weather file.kmz. Thank you i...

WUFI Plus 3.0がリリースされたことをWUFI Newsで知り、早々にインストール用zipファイルを落として、インストールを試みました。

結果は、ライセンス情報が2.xのものでは受け入れられず、インストールが進められず，途中で終了となります。ライセンスの更新手順も併せて、ご案内戴けますよう、お願い申し上げます。

Hello, Following to the announced in the news letter recently, we downloaded the zip file to install the updated version of WUFI Plus 3.0. In progressing the installation, it requires the registered user name, the organization and the license #. The former license information of WUFI Plus 2.x did no...

Hello, We got a reply in Japanese on the definite issue of radiant heat source in the forum on WUFI Japan. In order to double check the influenced conditions of this issue, I would wonder whether the distribution of incident solar radiation through a window can be affected by the issue. Please let u...

Hello, as a first request, the temperature profiles displayed are for the hottest day (2015/07/25) following your description and not for the shown time scale below the relative humidity? If you change the displayed time for one graph, the displayed time is not automatically changed for the other g...

現在可能な、放射器具を計算する方法は、ｈｓさんが行われた方法となります。 ・Inner Heat Source Radiant： 設定した熱量が、日射と同様に、室内の表面に、表面積の大きさに合わせて分配されます。表面が温まる（冷える）ことにより、伝達によって間接的に室内空気の温度に影響を与えます。 ・Inner Heat Source Convective： 設定した熱量が直接、室内空気のエネルギー量に加算（または除去）されます。つまり、直接、室内空気の温度上昇（低下）につながります。 上記の計算に関するバグについての報告はまだありません。 もしかしたら、設定された供給・除去熱量が小さく、室...

[results for East and West facades] 2Zones_East_West_DB.jpg The temperature profiles for the east and west zones in the hottest day also show mystical profiles. Since east zone seems to have a temperature peak in the morning, and west zone seems to show the peak in the late afternoon. Because the in...

[Results for South and North facade] The temperature profiles for the south and north zones in the hottest day show similar variations with a small temperature offset. 2Zones_South_North_DB.jpg The incident solar radiation profiles for the day are incredible since the northern solar radiation shows ...

Hello. This post is somewhat related to the former post on "explicit radiation balance". In order to double check the overheat issue caused by incident solar radiation, we set up simple two zones projects. Each zone has a geometry of 4m x 3m x 4m (W x H X D) and is connecting with each oth...

室内の放射冷暖房装置をWUFI Plusの中に組み入れた評価が出来ないかと検討しています。 現行バージョンでは冷暖房機器として取り扱いは出来ないので、放射冷暖房機器からの供給・除去熱量を以下の2項目として読み込ませて 擬似的な評価を試みようとしています。 ・Inner Heat Source Radiant ・Inner Heat Source Convective 簡単な予備計算を実施したところ、供給・除去熱量の放射成分を増やしても、室内温度には殆ど差違が生じないことが分かってきました。 そこで質問ですが、上記放射・対流の各成分で供給・除去熱量を与えた場合、特に放射成分は室内壁面温度の収支に...
