The Heat Balance

The article is devoted to the use of solar maps to determine the period of unwanted insolation and the amount of thermal radiation that penetrates into the tractor cabin throughout the entire working day. In addition, an optimal form of a sun-protection device has been proposed, which makes it possible to reduce the magnitude of the exposure dose of thermal radiation affecting the operator. Since solar radiation makes the main contribution to the heat balance of the cabins of mobile machines (tractors, combines, etc.), the results obtained can mainly be used in assessing the working conditions of operators and in calculating and choosing systems for normalizing the microclimate (ventilation and air conditioning).

The Heat Balance

Accidents of icing on catenary have great impacts on normal operation of trains. An on-line anti-icing technology used static var generator (SVG) for catenary was proposed, which can prevent icing formation without interrupting trains normal operation. The heat balance equations for catenary were solved, whose results were compared with data provided by TB/T 3111 and testing show the equation was correct. The simulation model based on Matlab was bulit , whose results and analysis show the correctness of the method.

Engine is carried the test on the thermal balance test and the drag test in the vehicle working condition to analysis the distribution of energy from combustion. The heat of coolant that combustion flow into the cooling system in different temperature is not the same. The results show that the engine heat comes into the cooling system ranging minimum at 3000-4000r/min, the effective power output accounts for the total energy up to 25% at full load reaching the maximum. Based on the data, it is established the control system of engine cooling module that can be controlled by the engine speed, torque and power, when the ECU reads the signal to forecast the combustion energy flow to the cooling system in the target vehicle working conditions establish the cooling module heat release control system.

Hot spot temperature (HST) is the most important parameter in the operation of power transformers. The HST has to be held under a prescribed limit. HST has a considerable effect on the insulation aging. Therefore detecting, monitoring and removing the HST could be a very important and necessary action for utilities. A new design of oil spraying and its effect, along with a thermal management in a transformer cooling system has been studied in this paper. The effect of oil fluid flow on the HST problem has been considered in this paper; and the calculations and simulation have been performed by Ants algorithm. The simulation results have been validated based on a 230/63/20 kV, 250MVA transformer at the Sari substation in Iran, and the results indicate that the new design could mitigate the limitations of transformer loading due to the HST problem. The Ants algorithm have been proposed and applied for accomplishing this task and to give an improved level of accuracy.

The Heat Balance

The paper presents the methodology of the analysis of the cooling system reconstruction in a food cold store under the regulations applicable from the beginning of 2020. They result from the so-called the F-Gas Act concerns the use of refrigerants with a low environmental impact. First, the elements of the existing regulations on the use of refrigerants were discussed. This part of article focus mainly on the F-Gas Act and the regulations it entails. Then, the refrigerants used so far in refrigeration systems were compared with substitutes, which were the only ones that have been approved for use since 2020, thanks to the low GWP index. Their properties are briefly described, along with the benefits (primarily for the environment) of their use. The main part of the work is the analysis of the reconstruction of the cooling system to use an alternative refrigerant. During the work, the construction of the cold storage was analyzed together with the system currently working in analysed location. Then, the heat balance was calculated, thanks to which it was possible to determine the demand for cold. Than, several refrigerants that meet the latest standards and application regulations were selected. Their operating parameters were examined, the possible variants of use were compared in relation to the determined demand for cooling and the most important operational features were summarized.
