HVAC system for Shopping Centre with Raspberry PLC

Control and Monitoring Professional Solution based on Raspberry Pi automation

Industrial Application of an Industrial PLC controller Raspberry

Shopping centres require a wide variety of HVAC (heating, cooling, ventilation and air conditioning) solutions to ensure consumer comfort and energy efficiency.

With an industrial Raspberry PLC from Industrial Shields, you can automate, control and monitor these installations. In addition, the remote programming of a SCADA system makes it possible to manage the HVAC installation's automation to ensure thermal comfort within the commercial premises.

Control of HVAC system for Shopping Centre



Heating, Ventilation and Air Conditioning (HVAC) is an indoor and vehicular environmental comfort technology that provides thermal comfort and acceptable indoor air quality.

HVAC is an important part of shopping centres, residential structures such as single-family houses, industrial buildings, among others, where safe and healthy building conditions are regulated regarding temperature and humidity, using fresh outdoor air.


The Gañar Group company requested the improvement of the design of an HVAC system to manage the heating, ventilation and air conditioning installations of a shopping centre. 

The goal was to automate, control and monitor the system with Open Source technology. Using a single PLC with the knowledge and recording of the operating hours, as well as the air conditioning parameters, Gañar Group wanted to remotely manage the monitoring of the entire process with quality technology and easy programming.

Raspberry PLC Ethernet 21+ I/Os


The solution suggested by Industrial Shields consists of installing a Raspberry PLC & GPRS 21 I/Os Analog/Digital PLUS industrial controller.

The installation of this Programmable Logic Controller provides the customer with an easily integrable solution because:

  • Using a variety of inputs and outputs, the controller can be easily integrated into an existing system.

  • It is a scalable system, which can be expanded without becoming obsolete.

  • Data transfer is improved to GPRS.


Gañar Group, together with its integration partner Square One Project Group, integrated an Industrial Shields Raspberry Pi based PLC in order to automate, control and remotely monitor a 5000 m2 area in Pretoria, South Africa.

Gañar first assessed the size of the HVAC unit required. Then, the company began manufacturing and programming the system once the laboratory tests were completed. Finally, the completed unit was shipped to the end customer for on-site commissioning.

Raspberry's GPRS and WiFi communications facilitate greater data transfer for remote monitoring in the SCADA system and greater data management.

Thanks to this application, the 5000 m2 of shopping area can be managed to improve the comfort and health of the mall.
