Condensation heat recycling system for heat engines

THE RELEVANCE of the research lies in the need to use waste heat, which is a byproduct of the operation of energy machines, to increase the efficiency of their operation. Using the example of introducing a system for recovering condensation heat and using it in an air heating system, the possibility of beneficial use of waste heat generated by refrigeration machines used to freeze the ice arena of a sports complex was confirmed.

TARGET. Development of a system for recycling the condensation heat of refrigeration machines to use waste heat when organizing air heating of a building.

METHODS. Study of engineering systems for the possibility of beneficial use of low-grade heat. Organization of a system for recycling the condensation heat of refrigeration machines in a sports complex. Installation of a measuring stand, including, among other things, a heat meter, a heat calculator, a controller for transferring measurement results to a personal computer, carrying out the necessary calculations, their subsequent processing and analysis.

RESULTS. At a facility with constant operation of refrigeration machines and a need for heating, a condensation heat recovery system has been introduced. The possibility of implementing the proposed system without long-term downtime of the main equipment is shown.

CONCLUSION. The introduction of a condensation heat recovery system increased the energy efficiency of the system, which allowed for 2.6 million rubles. reduce utility bills of the heat supply organization, as well as reduce thermal pollution of the environment by at least 1.4 GW per year.
