Justification of the Heat Network Project Based on the Simulation of Hydraulic Models When Connecting Consumers

The object of the study is the water heating network of a residential area of the city. According to the development plan, it is planned to build 9 residential buildings, and the first stage of construction, consisting of 5 houses, has already been implemented. The remaining buildings will be commissioned one per year. The article discusses the issue of an expedient option for the construction of a water heating network, taking into account the development of its configuration when connecting new buildings. The problem is the fact that the heating network of the first stage of construction was designed without taking into account further development, i.e. it is intended to supply the estimated amount of heat for only five buildings. To solve the problem, water heating networks of promising development were designed. When connecting buildings of the second and subsequent stages of construction to the existing network, the flow rate will increase, and consequently, the hydraulic resistance, pressure losses and energy costs for fluid transportation will change. Based on the hydraulic modeling of the heating network, taking into account the input of all construction stages, the cost estimate for the costs of pumping the coolant and the project for the reconstruction of the existing network with an increase in throughput, an expedient option for building the network was determined.
