This paper presents the calculation results of heat amount increase being typical for isothermal and cooling bodies where body plating has been broken causing the open way for water penetration into the insulating material and thus deteriorating the insulating properties of the damaged body fragment. During the service of the isothermal and cooling bodies the damages of their different fragments take place. A typical damage is abrasion of the side walls, damage to the joints of walls and walls with the roof and damage to the door edges. Using the thermovision camera and the algorithm described in [1], heat loss can be calculated for a fragment of the body that includes damage - an operational heat bridge that generates a variable heat flux being difficult or even impossible to be measured with heat flux density sensors. On the example of typical damages occurring in the serviced refrigerated body, they have calculated the amount of additional heat which may lead to the disqualification of the refrigeration body from refrigerated transport of sensitive goods, such as food and medical goods, bringing losses to transport companies.
