冷凍負荷計算|貫流・製品・侵入負荷をkW表示

冷蔵倉庫・冷凍庫の総熱負荷を、外壁からの貫流負荷、製品の予冷負荷、扉開閉による侵入負荷、その他内部発熱の4項目に分解し、それぞれkW単位で表示します。

Scenario

Standard engineering assumptions

ここでの冷凍能力(kW)は室内から除去する熱量であり、電力のkWではありません。消費電力≈冷凍負荷÷システムCOPに、補機負荷を加えたものです。

本結果はあくまで計画段階の試算です。最終的な能力、設備選定、冷媒、安全要件、価格、エネルギー性能は、選定した有資格の冷凍設備サプライヤーによる確認が必要です。

クイックアンサー

総冷凍負荷は4つの要素の合計です:外壁などからの貫流負荷、製品の予冷負荷、扉開閉による空気の侵入負荷、そして送風機・照明・フォークリフト・人員による内部発熱です。一般的な冷蔵倉庫では、貫流負荷が25〜40%、製品負荷が20〜45%、侵入負荷が15〜30%、内部発熱が10〜20%を占めます。

使用する計算式

総負荷=貫流負荷+製品負荷+侵入負荷+内部負荷・貫流負荷=U×A×ΔT

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建物寸法、パネル厚さ、外気設計温度を入力します。
  2. 21日あたりの製品入荷量とその入荷温度を追加します。
  3. 31日あたりの扉開閉回数と内部機器の負荷を設定します。
  4. 4各要素の内訳を確認し、総負荷(kW)を設備選定に活用します。

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

冷凍負荷はどのように計算しますか?

4つの成分の合計として計算します:外壁などからの貫流負荷(U×A×ΔT)、製品の予冷負荷、扉開閉による侵入負荷、そして送風機・照明・フォークリフト・人員による内部発熱。各成分をkWで算出し、合計が総冷凍負荷になります。本ツールは成分別の内訳を表示します。

パネルのU値はどの程度が目安ですか?

冷蔵用は0.25〜0.35W/m²K、冷凍用は0.18〜0.22W/m²K、ブラスト用は0.15W/m²K以下が目安です。

扉の開閉はどの程度負荷に影響しますか?

扉の開閉頻度が高い物流拠点では、侵入負荷が総負荷の15〜25%に達することがあります。

典型的な冷蔵倉庫における各要素の割合はどのくらいですか?

一般的な冷蔵倉庫では、貫流負荷が全体の25〜40%、製品負荷が20〜45%、侵入負荷が15〜30%、内部発熱が10〜20%を占めます。扉の開閉頻度や処理量によって割合は変動します。

この内訳結果をどのように見積もり依頼に活かせますか?

各項目の負荷(kW)に、建物寸法、パネル厚さ、製品入荷量、扉の開閉回数を添えてプロジェクト概要としてColdMatchに提出してください。ColdMatchは内容を人の目で確認したうえで、条件に合う独立系サプライヤーの紹介を検討します。サプライヤーの価格や性能を保証するものではありません。
