Refrig – Cargas de cajas de refrigeración

Descripción general

Refrig calcula rápidamente la carga máxima de refrigeración en btu por período de 24 horas para todo tipo de aplicaciones de refrigeración. Refrig tiene provisiones para todo tipo de cargas, incluyendo: techos, paredes, tabiques, pisos, productos, contenedores, infiltración, luces, equipos, personas, descongelamiento, tiempo de funcionamiento del compresor y más. Incluso está prevista una carga del factor de seguridad. Los datos meteorológicos de diseño están integrados y se buscan automáticamente en más de 300 ciudades diferentes. Las cargas de productos se acomodan fácilmente ya que Refrig contiene una biblioteca incorporada de productos (frutas, verduras, carnes, etc.). Todo lo que el diseñador tiene que hacer es ingresar el nombre del producto y la cantidad para obtener cargas automáticas de enfriamiento, congelación, subenfriamiento y respiración del producto. Una vez calculadas todas las cargas, el diseñador puede especificar el refrigerante y la TD deseada para poder seleccionar rápidamente un serpentín de evaporador y una unidad de condensación adecuados de la biblioteca integrada de serpentines y unidades de condensación. Refrig viene con más de 400 serpentines y 400 unidades condensadoras de varios fabricantes como Carrier, Krack, Witt, Russell y otros. Se pueden almacenar hasta 1.000 baterías y unidades condensadoras por fabricante.

Método de cálculo

El programa Refrig realiza cálculos de acuerdo con el Manual de fundamentos de ASHRAE y el Manual de refrigeración de ASHRAE. Todos los datos necesarios sobre productos y materiales se buscan automáticamente. Los resultados de salida calculados se pueden verificar fácilmente a mano.

FREQUENTLY ASKED QUESTIONS

What types of loads can Refrig accommodate in its refrigeration load calculations?
Refrig can accommodate a wide range of loads, including roofs, walls, partitions, floors, products, containers, infiltration, lights, equipment, people, defrost, compressor run-time, and more. Additionally, Refrig allows for a safety factor load to be included in the calculations. This comprehensive approach ensures that all relevant loads are considered when determining the maximum refrigeration load.
How does Refrig handle product loads in its calculations?

Refrig contains a built-in library of products, including fruits, vegetables, meats, and others. To calculate product loads, the designer simply needs to enter the product name and quantity. Refrig will then automatically generate the product cooling, freezing, sub-cooling, and respiration loads. This feature simplifies the calculation process and ensures accurate results.

What is the role of design weather data in Refrig’s calculations?

Refrig has built-in design weather data for over 300 different cities, which is automatically looked up during the calculation process. This ensures that the refrigeration load calculations are based on realistic weather conditions for the specific location. The designer does not need to manually input weather data, making the process more efficient and accurate.

How does Refrig select the appropriate evaporator coil and condensing unit for a given refrigeration load?

After calculating the maximum refrigeration load, Refrig allows the designer to specify the refrigerant and temperature difference (TD) desired. Based on this input, Refrig can quickly select an appropriate evaporator coil and condensing unit from its built-in library of over 400 coils and 400 condensing units from various manufacturers. This streamlines the design process and ensures that the selected equipment is suitable for the application.

Can Refrig accommodate custom coils and condensing units not included in its built-in library?

Yes, Refrig allows up to 1,000 coils and condensing units to be stored per manufacturer. This means that designers can add custom coils and condensing units from various manufacturers to the library, making Refrig a flexible and adaptable tool for refrigeration system design.

What is the significance of the 24-hour period in Refrig’s refrigeration load calculations?

Refrig calculates the maximum refrigeration load in BTUs per 24-hour period. This is important because refrigeration systems often experience varying loads throughout the day, and the 24-hour period provides a representative average load. By calculating the maximum load over this period, Refrig ensures that the designed system can handle the peak demand and maintain optimal performance.
