Employers will be hoping that a return to work will prove productive, reinvigorating the workforce and driving growth. To this end, however, they will need to instill confidence by demonstrating how they...

The modern technological world is filled with ‘extrusions’. They are all around us, in the form of small and not-so-small cross sections. The function of an extrusion is to form seals between components of complex machinery and keep them functional. And, depending on the ‘type’ used, they can make a big difference to how a machine operates. Some of the most desirable types of extrusion — and especially for use in HVAC systems — are those made from silicone. S...

Inverter driven air conditioning is more energy efficient, cheaper to operate and more profitable to install than its non-inverter driven equivalent. Here Neil Ballinger, head of EMEA at automation parts supplier EU Automation, explains how HVAC engineers can maintain the inverters in their customer’s aircon units. Do you remember cross country at school? It was exhausting; miles of seemingly pointless jogging and sprinting and, if the teacher was not looking, walking. If you were unlucky...

As a Managing Director of a company that provides temperature and humidity solutions to predominantly the warehousing and industrial sectors, I thought I would share my dilemma that I’m sure other business owners and managers also face. I don’t pretend to know the answers, but thought it might be worth sharing some of the considerations that I’m facing in whether to reshape, recruit and build or hunker down until the World, Europe and the UK offers some sort or predictability....

Control Systems have always played an important part in the function of HVAC systems and for many years were centered around the safe and optimum performance of the hardware deployed. Every HVAC system is a closed-loop process, with inputs fed into control logic that determines the best course of action to achieve the desired output. Energy management and integration into Building Information Management saw the advent of energy-saving techniques like free cooling and night-time purge reduce mec...

Sensors have been used in buildings since the invention of air conditioning to understand how buildings are performing, from in-room temperature sensors, to sensors on plant equipment, motors, ductwork and pipes. The Internet of Things (IoT) has enabled more sensors of different types to be deployed in more locations throughout the building easier than ever before. The point of installing and using IoT sensors is to gain deeper insight into how buildings are performing, and ensure buildings ar...
