SEER Ratings Explained: Determine Seasonal Energy Efficiency of Air Conditioning Systems What are air conditioning SEER energy efficiency ratings? How do we compare differences in seasonal energy efficiency or operating costs of different brands or models of air conditioners? What is a BTU or British...
In this connection, it is revealed that when a in the formula (3) is set within the range given by the following formula (4), more excellent pump efficiency can be obtained: 1.0≦α≦1.5 (4) Next, operation of the first embodiment is described. When energizing the pump from the...
94, 96 and an outer surface of plungers 98 and 100. The bearings reduce friction between the bore 94 and plunger 98 and improve the pumping efficiency. The bearings advantageously have brought the efficiency of the preferred pump from about 85 percent efficiency to about 98 percent efficiency. ...
Efficiency of an artificial lift installation is the useful power transmitted to the produced fluid,divided by the power of the electrical energy being supplied to the prime mover.This definition applies to electric motor prime movers.However,the output can be taken at the pump output,as it ...
1.A charge pump circuit, comprising:a first pump stage, including a first sub-pump coupled to a first pre-charge MOSFET transistor, wherein the first sub-pump is used to pump down a gate of the first pre-charge MOSFET transistor to thereby increase the pre-charge efficiency of the first...
However, the above pump has but low efficiency (η≉0.5) which is accounted for by a lower value of the flow coefficient (φ≤0.1) due to an increased cross-sectional area of the pump flow-through duct, a reduced value of the axial velocity (Ca) of the liquid flow and a separation...
