Vapor Compression Refrigeration | Refrigeration HVAC
The process of refrigeration uses the vapor-compression refrigeration cycle to move heat from one place to another. In many HVAC air conditioner and heat pump applications, the process of refrigeration or the vapor-compression cycle is what makes it work. This...
Natural Gas Versus Propane | HVAC Heating Fuels
Natural Gas Versus Propane | HVAC Heating Fuels - What is the best for you when choosing between either natural gas or propane? What is your heating system fuel supply? In some cases, you will not have a choice between the two. Having natural gas supplied to your home...
Gas Furnace Hot Surface Ignitor Electronic Ignition Systems
Hot Surface Ignitor - Whenever we talk about electronic ignition systems in gas furnace ignition systems we must first look at the key components which make these systems work and understand how they work. Hot surface ignitor systems work in various ways. This all...
Honeywell Temperature Fan Limit Switch Control
Honeywell Temperature Fan Limit Switch Control - The fan limit control turns the fan on and off in furnace applications. It works off of temperature and also provides a high-temperature safety limit. This is a switch, actually two switches, which turns the furnace...
Standing Pilot Gas Valve Propane Heating | HVAC Heating
Standing Pilot Gas Valve Propane Heating | HVAC Heating - How It Works. The standing pilot gas furnace uses a standing pilot to light the main burners. Many gas-fired water heaters have a standing pilot ignition system. The standing pilot gas ignition system is often...
Gas Furnace AFUE Definition | HVAC Terminology
Gas Furnace AFUE Definition | HVAC Terminology. AFUE or Annual Fuel Utilization Efficiency Heating systems consume approximately 35% to 50% of a typical home's energy budget. Therefore the government has come up with a way to measure efficiency ratings of furnaces so...
Electronic Ignition Gas Furnaces | HVAC Heating
High-Efficiency Electronic Ignition Gas Furnaces are here. They are the next step up from the standing pilot gas furnace. These gas furnaces are more efficient than the standing pilot furnaces but more complex in design. There are three types of electronic ignition...
Data Center Tridium HVAC Control Panel | Critical Facility
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...
Old McQuay Chiller Control Panel | Electro-Mechanical Controls
Old McQuay Chiller Control Panel - This panel is part of the controls for an older McQuay chiller. New chillers whether they be McQuay, Trane, York, or Carrier chillers still require these types of controls in them to make them work. This part of this...
Variable Air Volume Systems – Commercial HVAC
Variable Air Volume Systems - Variable Air Volume (VAV) systems are the best way to zone especially in large buildings. A VAV system with the proper controls and setup will help the building owner realize large savings in energy usage. There are many VAV systems out...
HVAC Damper Actuator for Economizer Free Cooling
HVAC Damper Actuator for Economizer Free Cooling - This damper actuator controls a free cooling damper for an economizer. It is part of an economizer damper system which allows free outside air cooling when the outside air temperature and humidity are ideal. In the...
How Hydronics Works | HVAC Technical for Consumers
How Hydronics Works | HVAC Technical for Consumers - Hydronics refers to using water and chilled water, steam boilers and hot water boilers, and other methods of transferring heat using water. A boiler or chiller is used to heat or cool the water and then the water is...
Rooftop Air Handler with Heat Recovery
Rooftop Air Handler with Heat Recovery - This large rooftop air handling unit also has a heat recovery wheel integrated inside the AHU itself. The all-in-one AHU and heat recovery unit saves energy by recovering heat. The heat would otherwise be vented outside in the...
Computer Room Air Conditioner Units | Commercial HVAC
Computer Room Air Conditioner Units - also referred to as CRAC units are essential inside data centers where cooling is necessary for all the computer and electrical equipment most data centers utilize. It is important to keep the equipment cool to prevent overheating...
Chilled Water Storage Tank | Critical Facilities
Chilled Water Storage Tank | Critical Facilities - Data centers use redundant systems for back-ups in case of an emergency. An HVAC chilled water storage tank adds an extra layer of redundancy to the process so if the chilled water plants crash the chilled water...
DX CRAC Unit Condensers | Critical Facility HVAC
DX CRAC Unit Condensers | Critical Facility HVAC - Most data centers do not utilize HVAC DX (Direct Expansion) CRAC units or air conditioning but instead use chilled water systems to provide cooling for the data center. In smaller buildings such as remote telecom...
How Cooling Towers Work | Commercial HVAC
How Cooling Towers Work - Cooling towers use evaporation cooling to cool condenser water from a chiller. Water is pumped to the top of the cooling tower, where the water flows down some flow plates to the cooling tower basin. As the water is flowing down the flow...
Chilled Water System Efficiency | HVAC Cooling
Chilled Water System Efficiency - Chilled water systems in HVAC are common in large commercial applications utilizing chillers to chill the water, a pumping system to pump the water (water and glycol systems are common), and chilled water coils inside air handlers or...
Chilled Water System Basics | HVAC Cooling
Chilled Water System Basics - Chilled water systems work much the same way as direct expansion systems work. The exception is they use water in the coil rather than refrigerant. Technically speaking, water can be classified as a refrigerant. Chilled Water systems can...
Building Commissioning Benefits | MEP Quality Control
Building Commissioning Benefits - The Building Commissioning Guide defines commissioning as a systemic process of assuring verification and documentation, from the design phase to a minimum of one year after construction that all facility systems perform interactively...
Outside Air Temperature-Humidity Sensor | HVAC Control
Outside Air Temperature-Humidity Sensor - The outside air temperature sensor uses a thermistor to read the outside temperature. This sensor also senses humidity using a humidity transducer. The temperature and humidity readings are collected by a direct digital...
DDC Integration | HVAC DDC Controls
DDC Integration | HVAC DDC Controls - This is an electrical project which is in the process of changing the old control system to a new DDC control system. Installing new controls in an occupied building takes plenty of planning to avoid interruption in air...
SCADA Supervisory Control and Data Acquisition
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...
Air Source Versus Geothermal Heat Pumps
Air Source Versus Geothermal Heat Pumps - A heat pump is an electric cooling and heating system. It is used to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer location. It can extract heat from the air,...
