Performance of a gas engine-driven heat pump system with R410A for cooling and domestic hot water applications 2023, International Journal of Refrigeration Citation Excerpt : When the engine is at high speed, the effect of ηeng is less than COP, and PER tends to decrease. If we did not ...
Since May, 1978, a block of flats in Dortmund, Western Germany, has had heating and hot water supplied by an air-to-water heat pump driven by a gas engine. Capacity is 465 kW and the unit has been able to provided this service unaided by supplementary heating with external temperatures ...
Further possible efficiency reductions come from the exclusion of oil and water pumps and fuel compressors unless they are driven by the engine crankshaft, and certainly from coolant temperature deviations for charge air cooling that differ from the low temperatures of the standard rating conditions. ...

Solar Stirling motor to drive water pumps has membrane as working piston, charged by working gas pressure on one side and medium to be pumped on other sideThe motor has a working piston formed by a membrane, charged on one side with working gas pressure and on the other side by a medium...
To evaluate the result of functionalization, the contact angle of water and air inside the channel is measured, with and without functionalization, see Fig.2b. For this, the microchannels are observed with an incident light microscope while water is inserted into the channel using a pipette. The...
For example, gas turbine engine, gas booster accumulator for the Sparrow series; gas turbine driven engine-hydraulic pump for the Aspide. 2. The gas generated by liquid gas generator is used as primary energy source. For example, gas turbine propellant delivery pump for the Sam 2 series; gas...
Compressors not covered are (a) integral gas-engine-driven compressors with single-acting trunk-type (automotive-type) pistons that also serve as crossheads and (b) either plant or instrument-air compressors that discharge at a gauge pressure of 9 bar (125 psi) or less. Also not covered are...
2BVC series water ring vacuum pumps and compressor is mainly used for sucking gases and water vapor .The ultimate suction pressure can reach 33mbar (abs) (i.e. 97 degree). When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long ...
