Cenários de energia e ciclo de vida
EnglishEspañolPortuguês (BR)FrançaisРусский

Calculadora de energia e custo de ciclo de vida de câmaras frias

Informe dimensões, temperaturas, entrada diária de produto e horas de operação. A calculadora dimensiona a câmara, estima a carga térmica e compara dois cenários de planta. Inclua sua tarifa e custos para comparar construir versus alugar ou 3PL. Ela nunca fornece tarifas, preços ou economias.

Método revisado em 13 out 2026 · Tradução pendente de revisão nativa.

1 · Câmara e produto

Área

200 m²

Volume interno bruto

1.200 m³

Carga térmica de projeto (com margem)

24,7 kW · 7 TR

Faixa de planejamento: 17,9–31,5 kW

Composição da carga: Transmissão 39% · Produto 6% · Infiltração pelas portas 46% · Cargas internas 8%

2 · Cenários de energia A e B

kW de refrigeração por kW elétrico, conforme dados de cada fornecedor nas suas condições de projeto.

Informe um COP maior que zero nos dois cenários.

3 · Ciclo de vida: construir ou alugar / 3PL (opcional)

Use valores cotados. Deixe vazio para pular.

Informe investimento e custo de aluguel para comparar.

Estimativa de planejamento. O projeto final, a escolha do refrigerante e a conformidade normativa exigem revisão de um engenheiro de refrigeração qualificado.

A ColdMatch é um serviço de compras gerenciado: você envia o projeto, nossa equipe revisa e estrutura, e contata fornecedores adequados por você. Não há conexão direta com fabricantes. Gratuito para compradores; projetos a partir de US$ 250.000.

Premissas e fontes

  • Propriedades do produto: calor específico 3,5–3,6 kJ/kg·K acima do congelamento, 1,8–1,9 abaixo, calor latente 240 kJ/kg em congelados, ponto de congelamento −2 °C (valores típicos do ASHRAE Handbook — Refrigeration, cap. 19, 2022).
  • Porta: 4,5 m², 30 s por abertura; densidade do ar 1,2 kg/m³.
  • Cargas internas, ventiladores e degelo seguem as premissas documentadas do modelo ColdMatch.
  • Margem de segurança e faixa de incerteza conforme a página de metodologia da ColdMatch.
  • COP, tarifa, investimento, manutenção e aluguel são informados por você.

Fórmulas

  • Volume = comprimento × largura × altura
  • Carga de projeto = (transmissão + produto + infiltração + internas) ÷ horas de operação × 24 × (1 + margem)
  • kWh anuais = kWh térmicos diários × 365 ÷ COP
  • Custo presente = investimento + Σ custo anual ÷ (1 + r)^t, t = 1…n

Perguntas

Como a carga térmica é calculada?

Soma quatro partes: calor pelas paredes, teto e piso; calor do produto que entra; ar quente pelas portas; e calor de iluminação, pessoas, empilhadeiras, ventiladores e degelo. O total diário é distribuído pelas horas de operação do compressor, com margem de segurança.

Por que devo informar o COP e a tarifa?

Eficiência e preço da energia variam com o projeto, refrigerante, clima e contrato. Usar dados do fornecedor e sua tarifa evita economias inventadas.

Posso usar unidades métricas e dos EUA?

Sim. Troque de unidade quando quiser; os valores são convertidos, não apagados.

Isso basta para comprar equipamentos?

Não. É uma ferramenta de planejamento. Um engenheiro qualificado deve confirmar o projeto e os fornecedores devem cotar com uma especificação completa.
