EXPERIMENTAL STUDY OF HEAT TECHNICAL PARAMETERS OF A SHELL AND TUBE HEAT EXCHANGER WITH A SPIRAL COIL

In the Russian Federation, housing and communal services are one of the sectors of the national economy. To provide consumers with heat and maintain a given temperature in conditions of constant heating and hot water supply of residential and public buildings, it is necessary to use heat exchangers. When solving engineering problems aimed at improving the design features of heat exchangers, it is necessary first of all to conduct a study of the thermal characteristics of the equipment used. This will allow you to identify equipment shortcomings and offer original lighting or recommendations for improving some elements. This is especially important when developing heat exchangers used in the housing and communal services of the fuel and energy complex of the Russian Federation. In this work, the thermal characteristics of a condenser heat exchanger with a spiral coil, controlled temperature parameters at the outlet of the heating and heated circuits were studied, the heat transfer coefficient K, [W/(m2×°C)], was calculated at various operating temperature conditions, and an algorithm for carrying out a natural experiment in a laboratory setup with a step-by-step description of the actions performed. The conclusions analyzed the results of experimental work on the apparatus, and also formulated proposals for the creation of a locally produced heat exchanger
