The intent of this course is to provide the background knowledge required to calculate the heat load of a refrigerated space (typically between 400F to -400F). It will break the heat load into four components: Transmission Load –sensible heat gain through the floor, walls and roof from the temperature difference across these surfaces.
The formula we will use for this calculation is; = 1.44 kWh/day Total internal load: We get a total of 3.6 kWh/day for the heat load from humans (2.16 kWh / day) and the lighting heat load (1.44kWh / day). Now, let’s calculate the heat load from the fan motors of the evaporators. 1000 = Watts to kW.
Room surroundings such as temperature and humidity is used for the calculation of heat transfer through the walls. Opening and closing the door to the cold room influences the heat load due to the air-exchange with humid air from the outside. The type of stored goods can be selected from the drop-down list.
Cold storage heat loads include product, transmission, infiltration, internal, and defrost. Accurate calculations are vital for energy-efficient design. ASHRAE standards guide load separation and estimation. Example showed a 19.14 kW load for a small cold room with apples. What is the most significant heat load in cold storage?
If they do, the respiration heat load is calculated based on the total mass of goods in the room. Important: The inlet temperature of the goods will be suggested at 5 K above the storage temperature. As previously mentioned, the selected goods specify the required room temperature and humidity.
To calculate this, we will use the following formula: 3600 = Converts kJ to kWh. That is when we calculate the cooling load from the new product entering the warehouse and the cooling load due to the respiration of the product; a total cooling load of 70.5 kWh/day (54.6+15.9). If the food product to be stored is a non respiring food, then, q = 0.
