HVAC monitoring

In the dry and cold winter, public sites such as shopping malls, commercial office buildings, metro stations, and museums are always moist and warm as in spring. It is all due to the HVAC system. As urban construction develops rapidly, the coverage capability of the HVAC system has to increase accordingly. Meanwhile, the requirements for environmental protection and energy saving of HVAC systems are also intensifying. As a result, the operation, maintenance, and monitoring of HVAC equipment have become more complicated than ever.

Monitoring the operation of tens of thousands of HVAC equipment distributed in buildings in the city requires the support of the Internet of Things. Through the detection, transmission and analysis of the operation data, The real-time conditions of the HVAC system can be traced. The IoT  solution for HVAC monitoring enabled by cellular technology can not only provide reliable connectivity and data transmission, but also facilitates the smart transformation of the existed HVAC systems, and also better manages the organic integration of the HVAC equipment with the cloud platform, so as to effectively improve the management efficiency of the HVAC system.

Case Description

Real-time Monitoring

The Large-scale HVAC system demands routine inspections. In the past, it needed lots of manual work but limited visibility into the performance was acquired. With the help of cellular networks, sensors equipped with wireless modules support real-time monitoring of the running status of HVAC components. And detailed data are transmitted to the cloud platform, and displayed in the form of charts and statistics based on computing and analysis so that managers can intuitively understand the real-time condition of the HVAC system. Residents and visitors can also access these data through smart devices such as mobile phones to check the indoor environment.

In addition, the IoT monitoring system provides 24/7 surveillance of the HVAC system with full coverage over water-cooled chillers, air-cooled cold-water heat pump units, hot water units,  air handling units, etc. Therefore, the monitoring efficiency can tremendously lift due to cellular connectivity.  

Automatic Control

With reliable cellular connectivity, HVAC systems can automatically adjust the temperature, humidity, air quality, and other environmental factors.

For example, the temperature sensor can transmit the room temperature to the management center. Combined with the analysis of historical operation data of each pumping station, data on outdoor weather, construction characteristics of the building, and other parameters, it can realize the precisely automatic adjustment of the room temperature.

Another example is that the air quality data is transmitted to the management center via cellular networks. And the system can automatically adjust the ventilation volume by comparing current data with the preset parameters so that the indoor air quality remains in a favorable state. The instant data delivery capability ensures that the HVAC system always immediately responds to the needs.

Predictive Maintenance

The HVAC system is almost in constant use around the clock. The accidental outage of the HVAC could be a troublesome issue in summer and winter, which means a highly unpleasant indoor environment. The predictive maintenance capability of the IoT monitoring system can effectively tackle the problem.

Owing to the reliable connectivity of the cellular modules, the management system on the cloud platform can obtain detailed and authentic operation data from each part of the HVAC. By analyzing these data, the system can determine when the failures of specific equipment may occur during the operation of the HVAC to prevent downtime caused by the malfunction. It not only saves costs and extra work for maintenance but also ensures the service personnel target the original problem and fix them as soon as possible with corresponding solutions.

Energy Saving  

Energy consumption from running HVAC is inevitably high so it needs to operate more efficiently by deploying the IoT monitoring system. Through the dynamic collection of environmental data and analyzing users’ preferences, the management system can proactively adjust the equipment to a proper state to avoid a large amount of cooling or heating redundancy. And the HVAC system will be turned off in the areas where users are not detected by the system.

The Users of the traditional HVAC system cannot break through the constraints of time and location.  With the support of cellular wireless modules, users can control the air conditioner through the network with terminals such as smartphones and preset the switching time to reduce power waste.

A centralized IoT management network for the HVAC system may be composed of thousands of sensors and devices. It requires reliable cellular connectivity to simplify management. The SIMCom LTE Cat.1 modules are specially optimized in terms of hardware and RF design for IoT applications, integrating with rich interfaces and software functions, which can support the rapid deployment of the HVAC management systems. It can help equipment manufacturers and maitainace service providers improve their services, lift energy efficiency, minimize the power bill, and continuously deliver a comfortable living and working environment for users.
