냉동부하 계산|전도·제품·침기 부하 분석

냉장창고와 냉동고의 열부하를 전도(외피), 제품 예냉, 침기(도어 개폐), 기타 내부 발열의 네 가지 요소로 세분화해 kW 단위로 산출합니다. 실제 프로젝트 사례와 실 m³당 W 기준값도 함께 제공합니다.

Scenario

Standard engineering assumptions

냉동 kW는 창고에서 제거되는 열량이며 전력 kW가 아닙니다. 전력 소비량 ≈ 냉동부하 ÷ 시스템 COP에 보조부하를 더한 값입니다.

기획용 추정치입니다. 최종 용량, 설비 선정, 냉매, 안전 요건, 가격, 에너지 성능은 선정된 자격 있는 냉동설비 공급업체가 확인해야 합니다.

빠른 답변

총 냉동부하는 외피 전도, 제품 예냉, 도어 침기, 팬·조명·지게차·인원의 내부 발열이라는 네 가지 요소의 합입니다. 일반적인 냉동창고에서 전도는 25~40%, 제품이 20~45%, 침기가 15~30%, 내부 발열이 10~20%를 차지합니다.

사용된 공식

총부하 = 전도부하 + 제품부하 + 침기부하 + 내부부하 · 전도부하 = U × A × ΔT

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.

자주 묻는 질문

냉동부하는 어떻게 계산하나요?

네 성분의 합으로 계산합니다: 외피 전도(U × A × ΔT), 제품 예냉, 침기(도어 개폐), 조명·모터·인원 등 내부 발열. 각 성분을 kW로 산출해 합산한 값이 총 냉동부하이며, 이 계산기는 성분별 내역과 총합을 함께 보여줍니다.

패널에는 어떤 U값을 사용해야 하나요?

냉장은 0.25~0.35, 냉동은 0.18~0.22, 급속동결은 0.15 W/m²K 이하가 일반적입니다.

도어 개폐는 부하에 얼마나 영향을 주나요?

출입이 잦은 물류센터에서는 침기가 전체 부하의 15~25%까지 차지할 수 있습니다.

이 계산기는 무엇을 입력받나요?

창고 치수, 패널 두께, 설계 외기온도, 일일 제품 반입량과 반입 온도, 도어 개폐 횟수, 내부 장비 부하입니다. 결과는 구성 요소별로 세분화되어 kW 합계로 제공됩니다.

결과를 설비 견적에 어떻게 활용하나요?

구성 요소별 kW 세부 내역과 총 냉동부하(kW)를 RFQ에 첨부하세요. ColdMatch는 이 브리프를 검토한 뒤 적합한 공급업체를 소개합니다.
