Different Companies Sometimes State Different Heat Outputs for the Same Radiators, Why?Calculating your heat output requirement from a radiator and finding the appropriate size of radiator can be confusing. For example: You provide your room measurements and your radiator specialist, Joe Bloggs Radiators, recommends that you need 1200 Watts heat output from your radiator. Consequently they recommend a radiator that meets your requirements; X radiator in white, 600mm high x 1000mm wide, which gives out 1264 Watts. However, your plumber tells you that the same radiator, X radiator in white, 600mm high x 1000mm wide but from his supplier, ACME Radiators, only gives out 1000 Watts. How can this be? The answer is probably that Joe Bloggs Radiators are advertising their heat outputs at the British standard whereas ACME Radiators are advertising their heat outputs using the newer European standard. To explain, heat outputs can be measured in 2 different ways; the way they are measured is done against the “delta T” or “Δt” of the system. In the UK, the standard for calculating heat outputs is illustrated by the following example: • Flow water temperature (on entering the radiator) – assumed to be at 90ËC • Return water temperature (on exiting the radiator) – assumed to be at 70ËC • This means the average water temperature running through the system is assumed to be 80 ËC • From this figure, you minus the average room temperature – assumed to be 20 ËC • This equates to the Δt60 ËC standard. In Europe, the standard for calculating heat outputs is illustrated by the following example: • Flow water temperature (on entering the radiator) – assumed to be at 75ËC • Return water temperature (on exiting the radiator) – assumed to be at 65ËC • This means the average water temperature running through the system is assumed to be 70 ËC • From this figure, you minus the average room temperature – assumed to be 20 ËC • This equates to the Δt50 ËC standard. To be clear, there is no difference in the radiator, it is just a different way of recording the performance. Like metric versus imperial; the numbers may be different, but they mean the same thing.
Do you like the new color printers’ speed and capabilities? Printer manufacturers make it very easy for organizations to utilize fast printing with excellent color by reducing the purchase price but clobber them with the cost of toner cartridges and other consumables to run the devices.
On the other hand, older printers are just as costly in the long run – they are inefficient, have very few capabilities and the average price of a black toner cartridge is $60 with a 3,000 page yield. In addition, because there is no other way to dispose of it, excess toner is usually thrown away instead of recycled, adding to carcinogenic waste in our landfills.
When you buy newer printers you get better toner cartridges that totally recycle excess toner as well as a recycling policy from the manufacturer. For example, HP sells you an ink cartridge with a prepaid return envelope making re-cycling convenient for you.
Whether you are a small- to medium-sized business or a large organization, you can consolidate a number of desktop printers with limited capabilities and high consumable costs into a multifunction printer (MFP) that prints, copies, scans and can send a fax – all in one machine. For your marketing needs, your MFP may also do high-resolution color printing.
Well, all that new technology is great but at what cost? The printer manufacturers will make it easy for you to acquire the devices and from a pure maintenance angle, consolidating 10 to 20 desktop printers into one MFP makes sense.
The new printers have more efficient toner cartridges with 5,000 to 10,000 page yields per black cartridge and 3,000 to 5,000 per color cartridge. Depending on the amount of color on a page, the page yield per cartridge can be significantly less, especially when printing presentations with a lot of solid color areas on the pages – this may result in as little as a 500 page yield for a color cartridge.
A person understanding the need for self discipline and a sincere understanding of the impact on the environment will not print anything they do not really need, select draft mode for all prints until the final version, and use only color when necessary, such as in marketing materials for use.
However, most of us do not belong to that group of people and need some help. This help can come in form of Document Output Management, where the management system enforces policies that reduce paper and toner waste.
For example, a 12-page presentation when printed in high- keluaran hk resolution full-color mode can cost as much as $5 whereas the same presentation in draft black and white mode would cost 36 cents and if printed in duplex 18 cents. If your users do not know this or just don’t care, you can be spending thousands of dollars per printer unnecessarily.
A Document Output Management System allows you to apply rules to certain users, printers and document types, so that shop floor workers can only print black, a manager can only print reports in color, the legal department can only print final contracts in high-resolution and other documents in black and white draft mode.
On top of the waste generated due to the lack of appreciation and the time it will take to educate staff in sustainability, there is the element of abuse of office equipment by printing, copying and faxing personal documents on equipment in the office.
