Recuperators in ventilation.

Modern conditions dictate a special attitude to the use of energy resources, both at the state level and at the level of ordinary civilian inhabitants. Constantly rising fuel and energy prices encourage every prudent person to take all possible measures to reduce their consumption with minimal impact on comfortable living conditions both in the home and in the workplace.

Fortunately today, thanks to modern technology, a large amount of equipment and materials have been created that provide significant savings compared to more recently.

This is especially evident in the development of ventilation equipment and components.
One of these components is a plate or cross-flow recuperator - good heat exchange equipment, which allows you to save a considerable amount of funds for heating or cooling air in the systems of tidal ventilation.

Why is this important?

As is known, high-grade high-quality ventilation involves the forced feeding into the premises of a building of fresh air from the street and the removal of waste air from it, saturated with moisture, carbon dioxide and other harmful substances, depending on the purpose of these premises.recuperator
In a cold time, when a temperature is artificially maintained in the building with the help of a heating system, a significant amount of heat is irretrievably removed from the premises by an exhaust ventilation system. Such heat losses account for a significant share in the total heat loss of the building.

How it works

The cross-flow recuperator, installed in the ventilation system of the building, allows you to select part of the heat of the exhaust air and pass it on to the heating of the tributary. In this case, the exhaust and tidal air are not mixed, and the heat transfer occurs through the thin plates, of which two interconnecting channels of the recuperator are formed. The efficiency of such a recuperator can range from 60 to 80%, depending on the parameters of exhaust air, its proportion to the inflow, as well as the nature of the work of the ventilation systems of this building.

Something similar happens in the summer in air-conditioned rooms, when the cooling of the warm external tidal air consumes a significant amount of energy.
In this situation, in the recuperator there is partial cooling of the tidal air exhaust and the thermal load on the compressor-condenser unit of the tidal system also decreases accordingly.
