HVAC Basics is a free informational resource providing information on training to become an HVAC engineer, as well as buyers guides for commonly bought HVAC appliances. The small line which carries the refrigerant from the condenser to the metering device is called the liquid line. ABSOLUTE ZERO - The temperature at which molecular activity theoretically ceases. Its goal is to provide thermal comfort and acceptable indoor air quality. You can get more information here. It is a device which is used to meter the refrigerant from the high value of pressure to low value of pressure by controlling the quantity of refrigerant that enters the evaporator coil. With HVAC units the two capacitors you'll likely run into are run capacitors and start capacitors. It gives the efficiency of an HVAC system and is directly proportional to it. Terms and Definitions HVAC – Stands for heating, ventilation, and air conditioning. horizontal flow— An air handler installed horizontally so that air moves from one side to the other and out into the ductwork. Dew Point Temperature – Temperature at which the moisture level in the air is considered to be saturated. In Hvac terminology the fan motor refers to the condensing unit while the blower motor refers to the air handler. The HVAC industry uses terms and vocabulary that may not be easily understood by the average homeowner. It's job is to move the motor wheel, which in turn pushes a volume of air into heating, cooling and ventilation applications. Acid is created when a compressor burns out, usually because the refrigerant reaches extremely high temperatures. When one substance becomes full of another substance, it is known to have become saturated. Coolers & Chillers are referred to as refrigeration. Measure the pressure of the liquid line. Some seem pretty obvious, but others may be confusing for … When the compressor motor burns out it can create so much heat that the refrigerant is burnt, which is what creates the acid. It is present in the condenser and is used to supply power to the fan motor & the compressor. What does HVAC mean? BTU/h: British Thermal Units per hour. Best 15000 BTU Window Air Conditioner Units, The Best Through the Wall Air Conditioners, HVAC Terminology, Glossary and Definitions. HVAC Certification Online: Online Training Guide for HVAC Technicians, Small Portable Air Conditioners – Reviews and Buyers Guide – 2020. In order to measure the superheat, you need to subtract the suction line temperature from the refrigerant temperature. Here are ten common HVAC terms you may hear your technician use during a service call. There is a difference between the temperature of the liquid line and the saturation temperature. HVAC Definitions Terms & Acronyms CAV – Constant Air Volume CD – Cold Deck (also Condensation Drain) It stands for High-Efficiency Particulate Air. Information and translations of HVAC in the most comprehensive dictionary definitions resource on … It stands for Seasonal Energy Efficiency Rating. HVAC Definitions - Heating. Annual Fuel Utilization Efficiency. It drives the condensate either outside the place or into some other kind of the main drain. Their size varies in accordance with the space they have to heat/cool. Normally, the vacuum is pulled up to a value of 500 microns.

The blower motor is located inside the air handler or furnace. This is a list of terms I have been compiling to help me study. There we talk more about HVAC and why it matters to you. Terms and technical definitions for heating, cooling and indoor air quality products. HVAC Definitions. The … Cooling-related units of measure-ment are also a source of confusion for IT personnel when assessing cooling needs. AFUE. The … Flooded – HVAC specific term. Blades are attached to the motor in order to move some amount of air. The higher the AFUE percentage, the more efficient the furnace. For proper drainage, the condensate drain line has a filter when the system is working. HVAC – Stands for heating, ventilation, and air conditioning. HVAC HVAC (heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental comfort. Heating in HVAC can be any number of heating systems from gas furnaces, electric furnaces, oil furnaces, oil and gas boilers, radiant heating systems, and heat pumps.The “H” stands for heating and comprises of all of the aforementioned ways of providing heat using different methods and different types of heating systems.
