HVAC Products Containing Mercury and Proper Disposal - Mercury is extremely harmful to the environment and causes severe health problems in humans and animals. For many years HVAC and HVAC Controls manufacturers have used mercury in switches.
Mercury is a liquid metal and provides a good source used in many switches because of its fluidity and conductivity. From thermostats to boiler controls the liquid metal provides a reliable and efficient switching mechanism to start and stop certain sequences in HVAC applications. (more…)
HVAC Control and Direct Digital Controls 2 - An HVAC technician who knows nothing about HVAC control systems would wonder how these HVAC control systems work. To understand HVAC controls, one must understand basic electricity and circuits.
DDC Automated Logic M-Stack - This Automated Logic M-Stack provides a control for multiple pieces of HVAC equipment and integrates network communication all in one single stack. This direct digital control system is integrated with pneumatic controls. DDC allows automated HVAC control processes to take place and adds higher efficiency to an HVAC system. (more…)
Data Center Tridium HVAC Control Panel - As data centers go and HVAC controls function are typically done controlled with either direct digital controls or a very complex SCADA system with direct digital controls being the preference in most situations.
Tridium is a developer of direct digital controls software and hardware and Tridium specializes in controls integration through the Tridium software they develop that allows different devices and different communication protocols to communicate to one another. (more…)
SCADA Supervisory Control and Data Acquisition - SCADA Gear in a large data center provides supervisory control and data acquisition (SCADA) to maintain electrical and mechanical equipment. SCADA System is used in many different industries for controls and security including DDC HVAC Controls. SCADA systems are an integration of PLC controls and offer an interface for technicians to monitor and control the equipment. SCADA can also be integrated with a DDC system and can offer remote monitoring over a network or internet. (more…)
Caution is always advised around mechanical and electrical equipment including the air handler. Turn the power off before removing any panels.
Air Handlers - An air handler is usually located in the garage, a closet, or in the attic (unless you have a package unit then the air handler is incorporated into one system). It is essential to any AC unit and heating forced air system. All AC units need an air handler or way to move air. It can be a part of your furnace and houses the evaporator coils, the blower motor, and some HVAC controls. It can be an up-flow, downflow, or horizontal flow AHU (air handling unit). (more…)
HVAC Tip - Having the proper humidity levels in your home or business is important not only for your health but also the amount of energy your HVAC systems use to keep you comfortable. If the humidity level is high in the summer you will not feel comfortable. If the humidity level is low in the winter you will not feel warm when the thermostat is set for an average temperature. This will result in turning the thermostat up to compensate and you will use more energy to stay comfortable. A properly designed and installed HVAC system will keep the proper levels of humidity in your home or business and save you money in energy costs by reducing the amount you use the HVAC system. For more information on humidity and maintaining the proper levels of humidity in your home please visit our humidity technical pages.
