Analysis of Ventilation System’s Heat Exchangers Integration Possibilities for Heating Season

Abstract

Ventilation systems are known as intensive energy used building engineering system. Heat exchangers are the main equipments used for energy transformation in building engineering systems as well as in ventilation systems. The conventional heat exchangers design methods do not belie the ways for efficiency energy use in building engineering system’s heat exchangers. The method of Pinch technology mostly used for industrial process integration that could be applied to analyze possibilities of process integration is first time adopted to evaluate processes integration of building engineering systems. The paper deals with analyze of integration possibilities of ventilation system. The approach covers several possible cases of integration. Analysis is based on heat exchangers used for heat recovery and heat transfer in ventilation systems modification cases during the heating season. As results for ventilation system integration possibilities there are represented heat exchangers modification solutions those are expressed as technical evaluation indicators of heat exchangers.
