Only emails and answers are saved in our archive. Additionally, in the event of a system failure, your new gas charge will be larger than what you reported—We call this “the can’t get 10 lbs of flour into a 5 LB sack” rule. Inaccurate system reporting is compounded when you consider that: 1) very few technicians use a scale when charging a system; and. All rights reserved, Get the latest HVAC/R and refrigerant management news on our, How to Calculate Your Refrigerant Charge Guide – Part 2 of 3, , I’d like to explain how to calculate your refrigerant charge properly and plus provide a, calculating refrigerant charge incorrectly, , most commonly techs and staff only read the “nameplate” capacity on the label of the compressor/condenser section and then they leave off the evaporator and the piping… (we show you how to properly calculate refrigerant charge in this quick guide here), ✔ 20-ton unit with 80 Pounds and leaks 10 pounds = leak rate of 12.5%, ✔ 20-ton unit with 49 pounds and leaks 10 pounds = leak rate of 20%. 2) that, although R-410A has 25 lbs in each cylinder, it is well-documented that at least 10% of that charge remains in the cylinder at all times, meaning that you only can get 22-23 lbs. It is also called as CFC-11, or R-11. Refrigerant A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. We don't collect information from our users. The factory charged systems are easy to identify—They are referred to as “packaged,” or stand-alone, and can include systems like vending machines (a few ounces) as well as all the way up to 150 ton packaged roof top units (hundreds of pounds). First, field-assembled equipment has 3 components that contain refrigerant: No complicated math required, you simply add together the gas in the pipe, the compressor/condenser section, and the evaporator = total charge. This colorless gas is better known as HCFC-22, or R-22, or CHClF 2. There are many problems with this process, but the most significant are the following: 1. However, starting 10 or more so years ago, regulations started to focus on leaks and indeed agencies began to write requirements that targeted equipment 50 lbs and over…. Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. For a, ✔ 20-ton unit with 80 Pounds and leaks 10 pounds = leak rate of 12.5% The dependence of the boiling point of Freon Refrigerant Pressure Temperature Chart: R407C, R410a, R134a, R404a: Freon r600 refrigerant pressure temperature chart R600 refrigerant … Chemical formula (R125 44% by weight): CHF 2 CF 3 Chemical formula (R143a 52% by weight): CH 2 CF 3 Chemical formula (R134a 4% by weight): CH 2 FCF 3 Molecular weight: 97.6 Boiling point at 1 atmosphere: -46.2℃ Temperature glide at 1 atm: 0.7K Critical temperature: 72.1℃ Critical pressure: 37.3 bar absolute ENQUIRE Underreporting of weight means that as systems leak – the leak rate looks larger. Ted is the President & CEO of Trakref, a cloud-based HVAC/R and refrigerant management software company that provides unprecedented solutions for commercial properties.

It is the simplest alkane with a tertiary carbon. Its chemical formula is CFCl 3 F. It is a colorless liquid that boils at around room temperature. The CFCs are a group of aliphatic organic compounds containing the elements carbon and fluorine, and, in many cases, As a result, they only capture between 30-40% of the system charge and therefore under report capacity charge. BOC offers a full range of next-gen HFO refrigerants, traditional HFC refrigerants R134a, R410a, R32 and R404a, plus natural refrigerants R744 (CO2 carbon dioxide) and R717 (Ammonia). Because if the nameplate was less than 50, then the tech didn’t have to record as much information…, (This is where you can get your refrigerant charge calculations wrong…). Think of it this way: Refrigerant is to an HVAC/R system what antifreeze is to a car. Related Topics . Basically, if someone had a 20 ton (non-packaged) unit with multiple air handling units (AHU’s), regardless of the piping, it would be assumed that the unit had somewhere between 60-80 pounds of refrigerant. In most cycles it undergoes phase transitions from a liquid to a gas and back again. If you under or over fill, then the car won’t operate as needed. And, feel free to grab a copy of our guide, “How to determine how much refrigerant gas is in your HVAC/R system.”, (Calculating total refrigerant charge—It’s an essential thing for you to know!). And somewhere along the way, instead of reporting normal system charges, we as an industry began to report only the nameplate.

Chlorodifluoromethane Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). out of each cylinder. Freon represents several different chlorofluorocarbons, or CFCs, which are used in commerce and industry. By 1935, Frigidaire and its competitors had sold 8 million new refrigerators in the United States using Freon made by the Kinetic Chemical Company. Buy your refrigerants gases from BOC today. Chlorodifluoromethane and chloropentafluoroethane mixture of Refrigerant gas R 502 with fixed boiling point, with approximately 49% chlorodifluoromethane. Back in the day, the system charge was always determined by the tonnage of the unit and then, depending on where you were located (cold vs warm climate), you would either choose 3 lbs per ton or 4 lbs per ton. (2) Practical limit according to EN 378-: it is used if the HC refrigerant of the system can leak into an occupied ambient.
