Abstract
Technical and economic comparison of typical facility for heat supply and indoor air-conditioning, which is operated on natural gas, with the facility working with the use of solar energy is conducted. It is shown that due to the integrated accounting of technical, economic, ecological and other aspects it is possible to solve an economic, scientific and technical problem of reduction of consumption of traditional fuel and energy resources. Application of technical and economic methods and information and communication technologies leads to strengthening of the requirements for economic efficiency of complex of marketing technologies of the high-technology enterprises. Since cost of gas and electricity is increasing constantly, there is a problem of reduction of their consumption by air conditioners. For refusal of electricity use, it is proposed to design a system of air conditioning on solar power. A growing environmental problems leads to necessity of application of air conditioning systems on solar power that are based on a difference of daytime and night-time air temperatures. Therefore, it is increasingly important to apply the combined solar facilities, which are used for heating during the cold season, and for cooling of premises during the warm period. The use of solar energy for air conditioning is also beneficial because the schedule of solar energy inflow coincides with the schedule of use of cold and because the addition of solar cooling to heating allows to improve economy of solar heat supply considerably. Costs of the facilities installation and maintenance as well as costs of using natural gas and electricity are analyzed. It is identified that users will spend 2.27 times more on purchasing and installation of the new equipment than on typical installation. However, they will spend 70 per cent less electricity in the air-conditioning mode and 310 m3 less natural gas in the heating mode every month. It is proved that throughout five years the user will spend UAH 104111.3 less than using typical facility. In the further engineering of system for heat supply and air conditioning in buildings it is offered to solve environmental problems, which depend on quantity of used natural fuel in scales of settlement, cities, countries.
