Technical solutions for the recycling of thermal energy and improving the environmental efficiency of engineering systems

Abstract

Objective. The article proposes design solutions aimed at the comprehensive modernization of the cold supply system of the ice palace "Puck" in Sochi, to reduce its impact on the environment.Method. A water reuse system has been created and a technology has been developed for using low-temperature heat that is released during the operation of the refrigeration machine.Result. A refrigeration plant has been developed that allows you to utilize, accumulate and direct the heat of condensation for the secondary use of thermal energy by other engineering systems at the facility, thereby reducing heat and greenhouse gas emissions into the Earth's atmosphere and increasing the technological capabilities of cooling.Conclusion. The proposed methods make it possible to make the necessary calculations and select equipment for the implementation of the developed systems in ice arenas.

The use of low-grade heat in dehydration processes of agricultural products

“…Depending on these factors, the actual value of the transformation coefficient can vary from 2.5 to 5.5 [6].…”
