This paper reports the thermal performance of a new cylindrical solar collector based on an experimental investigation with this difference that instead of the collector tube with absorbent coating, coil into a spiral copper tube is placed in the center of the collector. The spiral shape of the tube, heat transfer without disruption or increase the heat transfer area, is increasing. In this cas...

Climate change is the hottest topic today on earth. Traditional HVAC’s harm environment and stand out to be a major contributor global warming. One of many techniques mitigate current climate crisis by utilizing abundantly available solar radiation. Solar evacuated tube collectors are used absorb This power provide cooling technologies. Unlike conventional thermally driven absorption boon in to...

Food, cloth and shelter are three basic necessities of life. Food can be regarded as essential component for growth survival human being. So, the source cooking is one most important things in our daily lives. There various sources energy like kerosene, LPG, Firewood Renewable etc. them solar which a renewable energy. Solar cooks limited by fact that only take place during daytime. If thermal s...

An intermittent noise that occurs around 30 seconds after compressor start-up has been disturbing customers of many domestic refrigerator manufacturers over the past 10 years. This noise is very similar to that produced by popcorn popping, being referred to as popping noise. The most probable cause of this strange and unpleasant noise is thought to be CIS (Condensation Induced Shock). The aim o...

Substances in evacuated blood-collection devices produce gas-chromatographic peaks with retention times similar to those of drugs. All tubes tested except the serum separator tubes contained tris(2-butoxyethyl) phosphate, as determined by mass spectrometry. In addition, the partition coefficient during the solvent-extraction step increased for some drugs by as much as 40%, while for other drugs...

Submerged membrane distillation (S-MD) has been proposed as an alternative to conventional cross-flow MD systems desalinate hypersaline water. In S-MD systems, the hydrophobic is submerged in feed water tank that directly heated by electric heating element, eliminating need for pumping. this study, a solar-heated vacuum (S-VMD) system uses evacuated tube collector container proposed. Indoor tes...
