Abstract
. The algorithm of operation of the heat supply system in the mode of intermittent heating which considers features of operation of the building is offered. The purpose of the work is to assess the effectiveness of the use of intermittent heating for the educational building of the thermal laboratory of the Odessa Polytechnic State University. Currently, a project is being implemented to disconnect heat supply from the University boiler room and transfer the building of the University's heating laboratory to autonomous heat supply based on a condensing wall-mounted gas boiler. The combined heating system with the use of different heating devices (radiators, fan coils, climate panel, “underfloor heating” system) allows to study the dynamics of heating the laboratory premises with different thermal insulation and shielding of external and internal walls. The factors of reduction of energy consumption in the mode of program heat supply are analyzed in the work. Modeling of modes of operation of the heat generator of the heat supply system operating in the mode of intermittent heating is executed. The mathematical model of dynamics of heating of air in rooms taking into account features of operating modes and various types of heating devices as a part of system of heat supply is offered. For different climatic conditions the mathematical modeling of operating modes of the heating system is carried out and indicators of efficiency of work of system are received. The potential of energy saving for administrative, educational, office buildings depending on the heat-accumulating properties of external and internal wall structures has been studied. The expediency of using the Pontryagin maximum principle to increase the efficiency of morning flooding of buildings with different ones has been confirmed. accumulation time constants.
Highlights
For administrative, educational institutions, as well as office buildings, one of the ways to reduce energy consumption for heating is to use the mode of intermittent heating of the building
Proceedings of Odessa Polytechnic University, Issue 2(64), 2021 system is turned on to heat the air to a comfortable temperature until people arrive in the room
The use of intermittent heating is more effective for buildings with low storage capacity
Summary
Educational institutions, as well as office buildings, one of the ways to reduce energy consumption for heating is to use the mode of intermittent heating of the building. It is based on lowering the indoor temperature during the absence of people. Proceedings of Odessa Polytechnic University, Issue 2(64), 2021 system is turned on to heat the air to a comfortable temperature until people arrive in the room. The wide application of this regime requires the definition of the main directions for saving energy for heating
