The CLTD/CLF/SCL (cooling load temperature difference/cooling load factor/solar cooling load factor) cooling load calculation method was first introduced in the 1979 ASHRAE Cooling and Heating Load Manual (GRP-158) [1] The CLTD/CLF/SCL Method is regarded as a reasonably accurate approximation of the total heat gains through a building envelope ...
TI-36 SOLAR was based on 1985 version of TI-35 PLUS, but incorporates solar cells. It addition to standard features such as trigonometric functions, exponents, logarithm , and intelligent order of operations found in TI-30 and TI-34 series of calculators, it also include base (decimal, hexadecimal , octal , binary ) calculations, complex values ...
A calculator which runs on solar and battery power Through the 1970s the hand-held electronic calculator underwent rapid development. The red LED and blue/green vacuum fluorescent displays consumed a lot of power and the calculators either had a short battery life (often measured in hours, so rechargeable nickel-cadmium batteries were common ...
