Cold Storage Heat Load Composition and Dynamic Heat Source Analysis for Warehouse Design

Cold Storage Heat Load Composition and Dynamic Heat Source Analysis for Warehouse Design

Heat load calculation is the foundation of cold storage refrigeration unit selection. Multiple heat sources continuously enter cold room, and total heat load decides required cooling capacity of condensing unit and air cooler.

Heat enters cold storage from several channels. Enclosure heat infiltration transfers through wall, roof, floor and door panels. Hot air enters when cold storage door opens during loading and unloading. Newly stored goods carry sensible heat and respiration heat for fresh fruits and vegetables. Internal heat also comes from forklift, lighting, fan motors and staff inside warehouse.

Respiration heat is unique for fresh agricultural products. Fruits and vegetables keep breathing after harvest and release heat continuously, increasing refrigeration burden. Frozen goods have no respiration heat, only sensible heat when goods temperature drops to set freezing temperature. Door opening frequency and outdoor temperature greatly affect air infiltration heat.

Many project designers complete heat load calculation before ordering refrigeration equipment. XINDA REFRIGERATION EQUIPMENT carries out heat load analysis according to warehouse size, storage variety, temperature requirement and door opening frequency. Cooling capacity matching is based on multi heat source superposition.

Heat load analysis is required for all new-built business district cold storage, including fruit preservation warehouse, meat freezing room, medicine cold chamber and food ingredient temporary storage room. Seasonal outdoor temperature change will cause heat load fluctuation, and summer brings higher heat load.

Common problems caused by underestimated heat load include insufficient cooling capacity, temperature hard to drop, long continuous running time of compressor and high energy consumption. Overestimated cooling capacity leads to redundant equipment investment and low operation efficiency.

The investment of refrigeration equipment is directly related to calculated heat load. Reasonable heat load analysis helps select equipment with proper capacity, balancing upfront procurement cost and long-term running energy consumption.

Key design points include collecting warehouse dimension, storage type, daily cargo inbound volume, door opening frequency and local ambient temperature. For fresh product warehouse, respiration heat parameter must be included in calculation. Buyers should provide complete project information for heat load evaluation. XINDA REFRIGERATION EQUIPMENT provides cold storage heat load calculation service.

Daily operation management includes controlling door opening time, reducing frequent access in high temperature season, controlling batch quantity of warm incoming goods, and keeping enclosure panel intact to reduce heat infiltration. Damaged insulation panels will increase heat load continuously.

Full analysis of heat load and each internal heat source is the premise of correct refrigeration equipment selection. Project designers collect all related parameters and superimpose different heat sources to confirm required cooling capacity. Cooperating with professional manufacturers to finish heat load calculation can match suitable refrigeration equipment and achieve stable cold storage operation.
