UIC Leaflet No: 574 – Chapter 5 – Rolling Stock – Insulated, refrigerator and mechanically-refrigerated wagons and containers. Procedure to be followed for the determination of the thermic transmission coefficient of the body

UIC Leaflet No: 574 – Chapter 5 – Rolling Stock – Insulated, refrigerator and mechanically-refrigerated wagons and containers provides guidelines for determining the thermic transmission coefficient of the body in these types of railway vehicles. This coefficient is an important parameter used in the design and evaluation of the thermal insulation performance.

1. Purpose:

The purpose of UIC Leaflet No: 574 – Chapter 5 is to establish a standardized procedure for calculating the thermic transmission coefficient, also known as U-value, of the body in insulated, refrigerator, and mechanically-refrigerated wagons and containers. The U-value represents the rate at which heat transfers through the body and is crucial in assessing the energy efficiency and temperature control capabilities of these rolling stock units.

2. Technical Parts:

The leaflet defines the necessary steps to measure and calculate the U-value accurately. It outlines the equipment required, including heat flux sensors, temperature sensors, and data acquisition systems. The procedure includes conducting measurements during steady-state conditions and taking into account factors such as ambient temperature, internal load, and airflow.

3. Practical Using:

By following the recommended procedure, railway engineers and technical personnel can obtain reliable U-values for insulated, refrigerator, and mechanically-refrigerated wagons and containers. These values facilitate the comparison of different designs, materials, and construction techniques. They also aid in optimizing the energy efficiency of these rolling stock units and ensuring adequate thermal protection for temperature-sensitive goods.

4. Key Points:

– Accurate measurement of the thermic transmission coefficient allows for better evaluation and improvement of the thermal performance of rolling stock.

– The U-value helps in selecting appropriate insulation materials and designing efficient heating, ventilation, and air conditioning (HVAC) systems.

– Compliance with UIC Leaflet No: 574 – Chapter 5 ensures uniformity and standardization across the railway industry when assessing the thermal insulation properties of these types of wagons and containers.

In summary, UIC Leaflet No: 574 – Chapter 5 provides a standardized procedure for determining the thermic transmission coefficient (U-value) of insulated, refrigerator, and mechanically-refrigerated wagons and containers. This information is vital for assessing energy efficiency, optimizing thermal protection, and making informed design decisions. By following this guideline, professionals in the railway industry can enhance the performance and reliability of these rolling stock units.
