Since a majority of residential and industrial building hot water needs are around 50°C, an integrated solar water heater could provide a bulk source that blends collection and storage into one unit. This paper describes the design, construction and performance test results of one such water-heating device. The test unit has an absorber area of 1.3m 2 and can hold 170l of water, of which extractable...
The purpose of this article is to report the experience of design and testing of orifice plate-based flow measuring systems for evaluation of air leakages in components of air conditioning systems. Two of the flow measuring stations were designed with a β value of 0.405 and 0.418. The third was a dual path unit with orifice plates of β value 0.613 and 0.525. The flow rates covered with all the four...
