Improved recuperator unit with increased efficiency for use in mechanical ventilation systems

Abstract

Introduction. Engineering systems are an integral part of all buildings. It is they who provide a comfortable stay and provide vital activity for a person. The role of energy-saving measures used in the construction and operation of engineering systems is very important. With the help of these technologies and their improvements, energy conservation of natural resources takes place. Energy efficiency in technology helps humanity to reduce the cost of energy resources, but at the same time to ensure the necessary level of technological processes in buildings. This article will show the problem of energy saving in mechanical ventilation systems. To implement energy-efficient use of resources, an improved recuperator unit with an increased efficiency is proposed. Currently, for engineers, there should be a greater choice of used recuperator designs with an increased efficiency, which can be used for different types of objects and technical conditions.Materials and methods. The recuperator is offered as an analogue of existing samples and relates to the field of energy efficiency in ventilation systems.Results. An increase in efficiency compared to analogues due to an increase in the area of contact of heat carriers, due to a special internal design capable of more uniform heat transfer, due to a non-standard layout of the recuperator unit to avoid freezing and “defrosting” of condensate at the heat transfer surface. Application in many types of buildings, as there is minimal mixing of supply and exhaust air. The operation of the ventilation system is regulated by automation, in order to obtain a more comfortable microclimate in the room.Conclusions. The new design acquires an increased efficiency compared to analogues.
