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 - Carbon monoxide detectors are important to own for those people who burn fossil fuels for heat. Carbon monoxide is a flammable, colorless, odorless, tasteless toxic gas produced during incomplete combustion of fuel - Natural Gas, Oil, Coal, Wood, Kerosene, etc. Someone suffering from carbon monoxide poisoning generally has severe headaches, nausea, and sinus problems. These symptoms generally begin with mild effects and people usually remain unaware of what the exact problems are until, sometimes, it is too late. How many cracked heat exchangers or faulty furnaces are out there that no one knows anything about except a slight headache and nausea? Don't take any chances, get your carbon monoxide detector and call your local heating and air conditioning company for a heater inspection today. Read more on this subject on the Furnace Page.
