Technical and Economic Aspects of Using Heat Pump Systems for Heating and Cooling of the Moscow Subway's Facilities

Abstract:

This paper contains the results of research, carried out with financial support from the Ministry of Education and Science of the Russian Federation and dedicated to improving the energy efficiency of Moscow subway facilities and creation of stations with "zero" external sources heat consumption. This paper vindicates the possibility and economic feasibility of creating subway facilities with "zero" external sources heat consumption, equipped with heat pump systems for heating and cooling, which improve indoor climate comfort of subway's stations and halls. The research carried out by the authors proves the efficiency of using heat pump systems for heating and cooling in the Moscow subway. The proposed technology requires lower nonrecurrent capital investments than traditional technology, as well as enables to save up to 80 % of energy. Considering the current prices for connecting to the centralized heating systems, the technology in question pays back at the stage of construction. The possibility of stabilizing thermal conditions at stations and in halls of the subway is an important advantage of this technology. Tis paper proposes schemes of heat pump equipment usage that allows reversing it for operation in cooling mode, which provide sufficient air conditioning and humidity control at stations, halls and service rooms. The authors evaluate the heat emission of passengers, that is removed with the exhaust air, to be about 0.15-0.17 billion kW*h annually. Thus the Moscow subway just dumps outside about 2.4 billion kW*h of thermal energy, including heat emitted by passengers, annually. If recycled this amount of energy is sufficient to cover all subway's requirements for thermal energy.
