חישוב הספק קירור – קילוואט, BTU/h וטון קירור

חשבו את הספק הקירור הנדרש בקילוואט, BTU/h וטון קירור עבור חדר קירור או מנהרת הקפאה, בהתבסס על נפח החדר, סיווג הטמפרטורה והאקלים.

תשובה מהירה

הספק הקירור הנדרש הופך את עומס החום הכולל של החדר לקילוואט, BTU/h וטון קירור: 1 קילוואט = 3,412 BTU/h = 0.284 TR. עומסים אופייניים מנחים הם 40–60 וואט/מ"ק לחדרים מקוררים (0 עד +4°C), 60–90 וואט/מ"ק למחסני הקפאה (-18 עד -25°C) ו-150–400 וואט/מ"ק להקפאה מהירה, לפני מרווח ביטחון של 10–20%.

הנוסחה בשימוש

הספק (קילוואט) = נפח (מ"ק) × גורם עומס (וואט/מ"ק) ÷ 1000 × גורם ביטחון · BTU/h = קילוואט × 3412 · TR = קילוואט ÷ 3.517

כיצד להשתמש במחשבון זה
  1. 1הזינו את נפח החדר במ"ק (או אורך × רוחב × גובה).
  2. 2בחרו סיווג טמפרטורה ורמת בידוד.
  3. 3הוסיפו קירור מוצר ועוצמת פתיחות הדלתות.
  4. 4השוו בין ערכי קילוואט, BTU ו-TR והשתמשו בבוחר התרחישים כדי לצמצם הצעות מחיר מספקים.

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.

שאלות נפוצות

כיצד מחשבים את הספק הקירור הנדרש?

הערכה גסה: נפח החדר × גורם עומס אופייני לפי סיווג טמפרטורה — 40–60 וואט/מ"ק לחדרים מקוררים, 60–90 וואט/מ"ק למחסני הקפאה ו-150–400 וואט/מ"ק להקפאה מהירה — בתוספת מרווח ביטחון של 10–20%. הכלי מציג את התוצאה במקביל בקילוואט, BTU/h וטון קירור (1 טון קירור = 3.517 קילוואט).

איזה מרווח ביטחון כדאי להשתמש בו?

15–20% הוא הסטנדרט; עבור תרופות כדאי להוסיף גם עודפות N+1.

האם לטמפרטורת החוץ יש משמעות?

אקלים חם/טרופי עשוי להעלות את עומס התכנון ב-20–30% בהשוואה לאקלים ממוזג.

מהם ערכי וואט/מ"ק אופייניים לסוגי חדרים שונים?

בקירוב, 40–60 וואט/מ"ק לחדרים מקוררים (0 עד +4°C), 60–90 וואט/מ"ק למחסני הקפאה (-18 עד -25°C) ו-150–400 וואט/מ"ק להקפאה מהירה, לפני מרווח ביטחון.

כיצד להשתמש בתוצאה בבקשת הצעת מחיר?

כללו את ערכי הקילוואט, BTU ו-TR יחד עם נפח החדר וסיווג הטמפרטורה בכלי בקשת ההצעה. ColdMatch בודקת את התקציר באופן ידני לפני כל הצגה לספק.
