ダクト圧損計算Pro vs SetsubiWorks HVAC Sizing Calc

「ダクト圧損計算Pro」は、空調・換気設備のダクトサイズ選定と圧力損失計算を、現場で手早く行うための実務支援アプリです。 風量や目標風速などの条件を入力すると、角ダクト・丸ダクトの候補サイズを表示。選定後にサイズを変更した場合も、風速や適否をその場で確認できます。 【主な機能】 ・角ダクト、丸ダクトの推奨サイズ選定 ・角ダクトのアスペクト比設定 ・選定後のサイズ変更と風速判定 ・直管の圧力損失計算 ・エルボ、分岐、ダンパ、消音器、フィルターユニットなどの局部損失計算 ・機器やその他の圧力損失を複数追加 ・各区間と全体の圧力損失を確認 ・制気口、ガラリの開口風速計算 ・メーカー資料に記載された圧力損失値の入力 ・ダクトや圧力損失について学べる用語辞典 【こんな方におすすめ】 ・空調、換気、ダクト工事に携わる方 ・現場でダクトサイズをすばやく確認したい方 ・圧力損失や必要静圧を整理したい方 ・計算の意味を確認しながら使いたい初心者の方 入力から計算結果までを見やすくまとめ、現場でも迷いにくい画面構成にしています。複雑になりやすいダクト計算も、必要な項目を順番に入力することで確認できます。 ※本アプリの計算結果は、設計や施工を補助するための参考値です。実際の機器選定や施工では、設計図書、メーカー資料、各種基準および現場条件を必ず確認してください。

No more squinting at a calculator on site. SetsubiWorks puts nine calculations that HVAC and plumbing engineers reach for every day - design, site supervision, cost estimation - into a single app on your phone. The calculation logic is a native iOS port of an internal Django tool that has been used on real projects. WHAT IT DOES - Unit Conversion - primary energy conversion for electricity, city gas and COP - Air State Calculation - moist air properties from dry-bulb temperature and any humidity index (relative humidity, wet-bulb, dew point, absolute humidity) - AHU Psychrometric Chart - cooling and heating processes, capacity and water flow, with a natively drawn psychrometric chart - Air Conditioning Equipment Calculations - supply airflow, sensible heat load, coil water flow and required humidification - Duct Size Selection - spiral and rectangular duct sizes from airflow - Louver / Grille Size Selection - louver and grille sizes from airflow - Water Supply Pipe Selection - nominal pipe size from flow rate - Drainage Pipe Size Selection - drainage pipe sizing using the Manning and Kutter formulas - Equipment Combined Noise Calculation - combines the SPL of multiple units with distance attenuation BUILT-IN CALCULATOR ON IPAD On iPad, Duct Size Selection and Louver / Grille Size Selection come with a calculator panel. Enter several airflows as a formula, such as 1200+800+650x2, and the app adds them up and goes straight to sizing. With the calculator on the left and the results on the right, the large screen makes design reviews and drawing checks faster. WHO IT IS FOR A quick check on site, a rough figure during a meeting, some groundwork before an estimate - the moments where opening a laptop is overkill but a pocket calculator is tedious. Useful for design engineers, site supervisors and estimators, and for students checking their own answers while studying for professional qualifications. PRICING All features are free for 14 days after installation. After that, a single one-time purchase keeps every feature unlocked. There is no subscription and no monthly fee. DETAILS - Requires iOS 16.0 or later - No network communication, no data collection. Every calculation runs on your device - Available in Japanese, English, Simplified Chinese and Vietnamese - Results are reference values. Always have a qualified engineer verify them before applying them to actual design or construction Feedback and bug reports are welcome from the in-app settings screen or via the support link below.
