Abstract

Presently all more attention is spared to the problem of energy-savings in the system of centralized and decentralizing heat supply.of consumers. The decision of problem will allow to stabilize the system of payment for coolantmoderators due to the decline of the hidden losses of thermal energy. The sources of losses are situated : on thermal from uneffective work of heaters of network water and network pumps; in the heating systems in that losses arrive at, and sometimes and exceed 20% from the volume of heat that is passed, from ТЕЦ; on thermal points from uneffective work of heat-exchange vehicles. One of ways of decision of problem of energy-savings there is providing of reliable and effective work of heat-exchange equipment of the both centralized and decentralizing system of heat supply due to introduction on ТЕЦ and thermal points of the improved methods of planning and research of efficiency of heat-exchange vehicles of the system of heat supply. Foreign and general project organizations supply to the home consumer of variety of heat-exchangers, not giving complete information on technical descriptions of plastins and channels. A customer gets the specification of heat-exchanger, that contains the results of heating engineering calculations of coolant-moderators, amount of motions, common amount of channels. To check authenticity of project calculations and estimate actual efficiency of heat-exchange vehicles difficult. In this connection indisputable actuality of theoretical and experimental researches of the modes of operations of heat-exchange vehicles is with the aim of receipt of scientifically reasonable results for perfection of methods of planning and research of heat-exchange vehicles that is exploited.
