REVIEW

Diploma project on the topic: "Development of a heat supply system in the conditions of the Bizhbulyak RES" carried out at the Department of Heat Engineering and Energy Supply of Enterprises

General performance:

The completed diploma project contains 93 pages of a calculation and explanatory note, 8 sheets of graphic material in the format A1, and corresponds to the assignment issued by the department. The diploma project provides an overview of existing structures, with equipment selection, a heat supply system was designed due to the introduction of a radiator type heat exchanger, and an engineering calculation is given. Measures on safety and environmental friendliness of the project were developed, technical and economic assessment of design solutions was carried out.

Positive aspects of the work:

In the diploma project, the state of the question on the topic was analyzed, the necessary engineering calculations were carried out. The graphical part of the project is made using CAD.

Disadvantages:

1) The operation of the device used is not described in sufficient detail.

2) Some sections of the work do not refer to sources of information.

Conclusion: The topic of the diploma project meets all the requirements of the graduation qualification work and deserves to be rated "excellent," and the diploma student A. Gilemzyanov deserves to be awarded the qualification of an energy engineer.

INTRODUCTION

Air conditioning - automatic maintenance in closed rooms of all or individual air parameters (temperature, relative humidity, cleanliness, speed) in order to ensure mainly optimal meteorological conditions, most favorable for the well-being of people, conducting the technological process, ensuring the safety of values.

Air conditioning in rooms is provided to create and maintain in them:

- the permitted air conditions established by the standards, if they cannot be provided by simpler means;

- artificial climatic conditions in accordance with the technological requirements inside the premises or part of them year-round or during the warm or cold period of the year;

- optimal (or close to them) hygienic conditions of the air environment in production premises, if this is economically justified by an increase in labor productivity;

- optimal air conditions in the premises of public and residential buildings, administrative and multifunctional, as well as auxiliary buildings of industrial enterprises.

Nowadays, the design of air conditioning systems at the stage of developing an architectural project has become widespread.

In the 21st century, energy conservation in air conditioning, electronics production and other high-tech industries is becoming increasingly important.

Conclusion

The production of modernized radiators and the improvement of serial models does not lose their relevance today, which is explained by the daily growing demand for heat energy from gas (for oil companies), as well as the complexity and high-cost construction of fuel mains to remote industrial, residential and public buildings and structures from main mains or fuel stations. Therefore, the use of heat supply systems designed on the basis of air conditioners and gas boilers has quite great prospects in the near future.

Improvement of radiator structures will make it possible to increase efficiency of use, increase power at constant dimensions, reduce labor costs during operation.

The proposed off-season heating system does not require district heating.

It should be noted that the air conditioner modernization process does not require significant capital investments and does not differ in the complexity of structural execution, which positively affected the payback period of the proposed improvement (additional capital investments amounted to 40,500 rubles, the payback period is months).
