Overview
Refrig quickly calculates the maximum refrigeration load in btu’s per 24 hour period for all types of refrigeration applications. Refrig has provision for all kinds of loads including: roofs, walls, partitions, floors, products, containers, infiltration, lights, equipment, people, defrost, compressor run-time, and more. There is even provision for a safety factor load. Design weather data is built-in and automatically looked up for over 300 different cities. Product loads are easily accommodated as Refrig contains a built-in library of products (fruits, vegetables, meats, etc.). All the designer has to do is enter the product name and quantity to get automatic product cooling, freezing, sub-cooling, and respiration loads. After all loads have been computed, the designer can specify the refrigerant and TD desired so that an appropriate evaporator coil and condensing unit can be quickly selected from the built-in library of coils and condensing units. Refrig comes with over 400 coils and 400 condensing units from various manufacturers such as Carrier, Krack, Witt, Russell, and others. Up to 1,000 coils and condensing units can be stored per manufacturer.
Calculation Method
The Refrig program performs calculations in accordance with the ASHRAE Handbook of Fundamentals and the ASHRAE Refrigeration Handbook. All necessary product and material data are automatically looked up. Computed output results can be easily verified by hand.

FREQUENTLY ASKED QUESTIONS
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.
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.
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.
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.
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.
