Remote Monitoring Unlocks Immense Efficiency In Urban Heat Supply Systems

I. Introduction

A. The Crucial Role of Urban Heat Supply Systems

Reliable and adequate urban heat supply solution are crucial for ensuring the comfort, productivity, and economic activity of modern cities and their citizens. Different types of heat supply systems cater to this requirement including district heating networks that supply heat generated at a central location to multiple buildings, as well as individual heating solutions like boilers in each building.

Urban district heating systems distribute heat generated in a centralized location through a network of insulated pipes to residential and commercial buildings across a city. Steam or hot water is used as the heat transfer medium at typical temperatures between 50°C to 120°C. These systems achieve greater efficiency and regulation compared to individual boilers and help reduce greenhouse gas emissions from cities. Many European cities extensively utilize district heating in meeting over half of the heat demands.

Individual gas or biomass boilers, as well as electric heating installed directly in buildings, can also serve as heat supply systems. However, their efficiency and emissions levels are typically suboptimal. There is also a lack of active monitoring and regulation capabilities with such systems.

urban green solutions like waste heat recovery and geothermal energy are seeing increasing adoption in cities for meeting heat demands in an eco-friendly manner. However, their economic feasibility depends on availability and local geographical conditions. There is a need to leverage technological capabilities like remote monitoring for wider adoption.

B. Challenges of Traditional Monitoring Methods

While heat supply fulfills an essential requirement for urban living, traditional methods have significant limitations in monitoring and maintaining these intricate systems in optimal conditions. Manual meter readings, inspections of pipelines and equipment either on foot or in vehicles to check for leaks, damages or corrosion is time-consuming, expensive and proves insufficient for modern smart cities.

Such manual periodic monitoring has very low data granularity given its sparse and lagged nature. Critical events like leaks or abnormal functioning may go undetected for long periods leading to energy waste, damages and disruption of supply services. Long term data collection and trend analysis is also inadequate to understand usage patterns and dynamically optimize operations. The overall inefficiency drives up the operating costs substantially.

There are also major safety and hazard risks associated with the manual inspection of leak-prone pipeline infrastructure carrying steam or hot liquids. Limitations during unfavorable weather conditions further compound the reliability issues. Modern cities require a sophisticated and networked urban heat supply monitoring infrastructure for operational efficiency, fail-safe planning and sustainability.

II. Introducing Remote Monitoring Technology

A. What is Remote Monitoring?

Remote monitoring refers to the technology and collection of solutions enabling the observation and tracking of appliances, systems or entire industrial processes continuously from distant locations. It relies on installing an extensive sensing system across the equipment and pipelines combined with wired or wireless communication hardware to transmit sensor data automatically to a central location.

Advanced software systems then aggregate, store, analyze and help visualize this data while applying intelligence algorithms, predictive analytics, and machine learning techniques. Remote monitoring creates digital twins of physical assets and leverages automation and self-regulation wherever applicable. Operators gain actionable insights based on rich analytics to optimize performance proactively.
