Trả lời nhanh

Chi phí điện hằng năm của kho lạnh bằng average electrical load × operating hours × tariff, cộng phí nhu cầu công suất (kVA). Hệ thống lạnh thường chiếm 60–70 % hóa đơn điện của kho lạnh; cơ sở vận hành tốt tiêu thụ khoảng 30–55 kWh mỗi m³ mỗi năm với kho mát và 55–95 kWh/m³/year với kho đông.

Công thức sử dụng

Annual cost = kW × hours/year × load factor × tariff (USD/kWh) + peak kW × demand charge × 12

Cách sử dụng công cụ tính toán này
  1. 1Nhập công suất điện của hệ thống theo kW và số giờ vận hành.
  2. 2Thêm giá điện theo USD/kWh và mọi phí nhu cầu công suất hoặc phụ phí giờ cao điểm.
  3. 3Áp dụng hệ số tải phản ánh chế độ tải theo mùa.
  4. 4Đọc kWh và chi phí hằng năm, rồi kiểm tra khả năng tiết kiệm bằng bộ chọn kịch bản.

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.

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.

Câu hỏi thường gặp

Hệ số tải là bao nhiêu?

45–65% là mức điển hình; buồng cấp đông gió có thể giảm xuống 40%.

Điều khiển thông minh có thể tiết kiệm bao nhiêu?

Quạt EC, điều khiển áp suất ngưng tụ thả nổi và xả đá thích ứng giúp giảm kWh 15–25%.

Phí nhu cầu công suất là gì?

Trong biểu giá kVA/kW, khoản phí này làm tăng 20–35% so với chi phí chỉ tính theo kWh.

Chi phí điện hằng năm được tính như thế nào?

Annual consumption = refrigeration duty ÷ COP × running hours × load factor; annual cost = that consumption × your tariff, cộng phí nhu cầu công suất hoặc công suất đăng ký nếu hợp đồng có quy định. Phí điện năng và phí công suất được trình bày riêng để giá kWh thấp không che khuất phí nhu cầu công suất cao.

Tôi nên nhập mức giá điện nào?

Dùng chi phí bình quân mỗi kWh thực trả trong năm trước từ hóa đơn thực tế — không dùng mức giá niêm yết. Nếu đơn vị điện lực thu phí công suất đăng ký theo kVA hoặc kW, hãy tính cả khoản này; trong biểu giá kVA/kW, phí nhu cầu công suất thường tăng thêm 20–35% so với chi phí điện năng thuần.

Làm thế nào để đối chiếu kết quả với hóa đơn thực tế?

Chia tổng kWh năm trước cho thể tích kho lạnh: kho đông công nghiệp thường tiêu thụ 60–100 kWh mỗi m³ mỗi năm, còn kho mát là 25–40. Nếu mức tiêu thụ thực tế nằm xa ngoài khoảng này, COP hoặc số giờ vận hành trong mô hình chưa đúng — và công cụ tính tiết kiệm năng lượng được thiết kế để thu hẹp khoảng cách đó.

Có thể dùng công cụ để so sánh hai phương án hệ thống lạnh không?

Có — chạy công cụ một lần cho mỗi phương án với COP và đặc tính tải riêng, sau đó đưa cả hai kết quả hằng năm vào công cụ tính ROI cùng CAPEX tương ứng. Cách này chuyển chênh lệch kWh thành chênh lệch thời gian hoàn vốn, là cơ sở nên dùng để so sánh nhà cung cấp.
