PURON – a term used by Carrier, Bryant, for the refrigerant 410A. Sends extra voltage to help start up compressor. Isometric view on Auto cad 2014, where we drawing on in the course, is more tedious, so i loved drawing it this way, as i found it more simple, as i just had to connect points to points. E.G. Overcharge, low condenser air flow due to improper motor or blade or dirty condenser coils. (Usually -. Unlike supply vents return vents are normally not adjustable. Dehumidification – the act of removing moisture from the air. Discharge line is the line in which the refrigerant passes through after being discharged by the compressor. The amount of heat needed to change 1 pound of water, by 1 degree, in one hour. EXTERNAL STATIC PRESSURE - The sum of the static and velocity pressures of a moving air system at the point of measurement. Blower Wheel – Attached to the blower motor. nmpl = … Heat Load Calculation – The amount of refrigerant and air flow it is going to take to heat or cool a space or place. HEAT FLOW - Heat flows from a warmer to a cooler substance. CFM – Cubic feet per minute. CUBIC FEET PER MINUTE - A common means of assigning quantitative values to volumes of air in transit, usually abbreviated CFM. Compressor – Compresses refrigerant to allow it to flow through the refrigeration cycle. We don't collect information from our users. RADIATION - The transfer of heat without an intervening medium. A good practice for technicians is to pull a vacuum to 500 microns or less. MERCURY MANOMETER - Used to measure vacuum in inches of mercury. Enter the condensate line, which essentially functions as a drain line. FILTER-DRIER - A device that removes moisture, acid and foreign matter from the refrigerant. Dampers – these can be installed of duct work in zoning systems, so that the designated room can call for heating or cooling. VACUUM - Any pressure below atmospheric pressure. CONDENSATION POINT - The temperature at which the removal of any heat will begin a change of state from a vapor to a liquid. HVAC … HEAT - A form of energy causing the agitation of molecules within a substance. LATENT HEAT OF CONDENSATION - The amount of heat energy in BTU's that must be removed to change the state of one pound of a vapor to one pound of liquid at the same temperature. CAPILLARY TUBE - A refrigerant control consisting of a small diameter tube which controls flow by restriction. Preventative Maintenance (PM) – A series of preventative measures to keep your system operating efficiently. Discharge Line: The high pressure, hot gas line coming out of the compressor. SUCTION LINE ACCUMULATOR - A device located in the suction line that intercepts quantities of a liquid refrigerant and thereby prevents damage to the compressor. Steel liquid-line driers are intended for use in all sizes and types of systems. ABSOLUTE HUMIDITY - The weight of water vapor in a given amount of air. Many factors go into heat load calculations. Algae – The number one cause of drain line back ups in humid climates. PITCH - The slope of a pipe line for the purpose of improving drainage. DRY AIR - Air which contains no moisture vapor. In the case of heat pump … PRECHARGED LINES - Refrigerant line's which are filled with refrigerant and are sealed at both ends. The end of the waste pipe should be cut at 45 degrees where it terminates into the grid to help reduce the potential for the pipe to freeze. VAPOR BARRIER - The term applied to an impervious layer of material superimposed upon a layer of insulation. You can find an extremely accurate dew point calculator here. REFRIGERANT VELOCITY - The rate at which refrigerant is moving at a given point in a system, usually given in feet per minute (FPM). Saturation – An HVAC term describing a substance when it contains all of another substance it can hold. The quantity, or mass of air moving in one minute. Wine cooler, Ice Makers, Walk-In Freezers…. Also, when you've done that, check the temp drop across the evap and ensure you aren't cooling … 240 volts to 24 volts. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Only emails and answers are saved in our archive. This could be gas, liquid or solid. These driers are physically sized to minimize pressure drop and provide adequate volume for filtration and drying. Step 3. They are basically the heart of the refrigeration cycle and often the most expensive component in an hvac system. Thanks for your site i printed your drawing schematic of Basic Electric Wiring And Heating, for my ENT-131 course, as part of my finals. IAQ – Acronym for Indoor Air Quality. Example sentences with "discharge line", translation memory. Vapor – gaseous state of refrigerant. STATIC PRESSURE - The normal force per unit area at a small hole in the wall of a duct. Return Vent – Normally where the air filter goes in some cases. Tightening the quick connections ruptures the seals on the fittings and the line charge becomes part of the total system charge. Solenoid – a valve that stops of flow of fluid or gas (refrigerant). Some super-heating usually takes place. Package Unit – A single unit that consists of the evaporator, condensing coils, heaters, compressor, fan and blower motor all in one unit. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. E.G. Heating Ventilation Air Conditioning Training For Beginners. High voltage – There is no set voltage to be considered high when it comes to HVAC, but anything over 50 volts is a good place to start. The reciprocal of density. If you have central heating and air system this means that you also have a lot of ducts running through the home. discharge - traduction anglais-français. This second part describes the design procedure of the suction and discharge lines according to what suggested by ASHRAE Handbook (2006). DISCHARGE LINE - Line connecting compress outlet to the condenser inlet. OHMS – Current is equal to Voltage divided by the resistance. DRY BULB TEMPERATURE - Temperature read with an ordinary thermometer. Over time, the gaskets that seal the refrigerant hoses can break down and begin to leak refrigerant. RECEIVER - A vessel for holding refrigerant liquefied by the condenser. Someti… It also serves as a dividing point between the high and low pressure sides of the system. Static Pressure in our industry has a unit of measure equivalent to inches water gauge. For example, a 30 amp breaker should trip should that line exceed 30 amps. Supply – The air leaving the air handler or furnace, and us usually directed through supply grills throughout a place. LIQUID LINE - A tube used to convey the liquid refrigerant from the condenser outlet to the refrigerant control device of the evaporator. Only used at saturated conditions. High humidity inside of homes <60% could cause bacterial growth. When either the condensing coil or evaporator coil contains excessive liquid refrigerant. Ventilation – changing the amount of air in a place, exhaust fans are one example of a type of ventilation in HVAC. Transformer – a device that reduces the amount of voltage. Some smaller parts that make up the condenser are capacitors and contactors. ENTHALPY - Total amount of heat in one pound (kg) of a substance calculated from accepted temperature base, expressed in BTU's per pound mass (J/kg). KW – Kilowatt. Vaporization – The state of liquid changing into gas. This humidity eventually turns into condensation that must have somewhere to go. The amount of heat required to melta  ton of ice at 32 degrees F. Typical residential homes have air conditioners that are 2-5 tons or more depending on size of home. COMPRESSION RATIO - The ratio determined by dividing the discharge pressure, in PSI (Pa), by the suction pressure in PSI (Pa).
