冷却能力の計算|kW・BTU/h・冷凍トン換算

冷蔵倉庫やブラストフリーザーに必要な冷却能力を、kW・BTU/hr・冷凍トンの3単位で同時に算出できます。複数の見積もりを比較する際の基準値としてご活用ください。

クイックアンサー

冷却能力計算ツールは、倉庫全体の熱負荷をkW・BTU/hr・冷凍トンに換算します:1kW=3,412BTU/hr=0.284TR。目安の負荷密度は、冷蔵倉庫(0〜+4℃)で40〜60W/m³、冷凍倉庫(−18〜−25℃)で60〜90W/m³、ブラストフリーザーで150〜400W/m³で、これに10〜20%の安全率を加えます。

使用する計算式

冷却能力(kW)=容積(m³)×負荷係数(W/m³)÷1000×安全係数・BTU/hr=kW×3412・TR=kW÷3.517

ColdMatchの冷凍技術エンジニアが監修

この計算ツールの使い方
  1. 1倉庫の容積(m³)を入力します(または縦×横×高さ)。
  2. 2温度クラスと断熱仕様を選択します。
  3. 3製品予冷負荷と扉開閉の頻度を追加します。
  4. 4kW/BTU/TRの結果を比較し、シナリオ選択機能で複数の見積もりの妥当な範囲を把握します。

Limitations

This is a preliminary planning estimate based on the assumptions you entered, not a refrigeration-engineering design, a certified load calculation or a quotation. Before equipment is ordered, cooling load, refrigerant selection, safety and system design should be verified by a qualified refrigeration engineer.

Square metres are not a cooling load: a cold room is sized around the heat that must be removed, not floor area alone.

Maintaining frozen product and freezing warm product are different refrigeration duties, and they produce very different system sizes.

Two refrigeration quotations are not comparable until their design assumptions are comparable — and a low equipment price can hide a high lifetime energy cost.

Next procurement step

Use this result as the starting point for a ColdMatch project request. Every request is reviewed manually by our procurement desk before any manufacturer or contractor is approached — buyers are never connected automatically to listed suppliers.

Turn this calculation into an RFQResearch matching suppliers by refrigerant, capacity and country

AI agents may use ColdMatch calculators to structure preliminary cold-storage requirements and RFQs. Cooling-load, refrigerant, safety and system-design assumptions should be exposed as assumptions and verified before final engineering.

よくある質問

冷却能力はどのように計算しますか?

概算は「室容積 × 温度クラスごとの負荷密度」で求めます。冷蔵(0〜+4℃)で約40〜60 W/m³、冷凍(−18〜−25℃)で約60〜90 W/m³、ブラストフリーザーで約150〜400 W/m³に、10〜20%の安全率を加えます。本ツールは結果をkW・BTU/hr・冷凍トン(1TR=3.517kW)で同時に表示します。

安全率の目安はどのくらいですか?

一般的には15〜20%が標準です。医薬品用GDP倉庫では、これに加えてN+1の予備能力を確保することが推奨されます。

外気温度は計算に影響しますか?

大きく影響します。温帯気候と比べ、高温地域や熱帯多湿地域では設計負荷が20〜30%増加することがあります。

温度クラスの区分はどうなっていますか?

冷蔵(+2〜+8℃)、冷凍(−18〜−25℃)、ブラストフリーザー(−35〜−40℃)、医薬品GDP(+2〜+8℃)の4区分があり、それぞれ異なるW/m³の基準負荷密度が設定されています。

算出結果はどのように活用すればよいですか?

kW・BTU/hr・冷凍トンの3つの結果と、容積・温度クラス・気候条件をまとめてRFQに記載してください。ColdMatchは内容を人の目で確認したうえで、適切な独立系サプライヤーの紹介を検討します。価格や性能について保証するものではありません。
