Improvement of refrigerating machine energy efficiency through radiative removal of condensation heat
نویسندگان
چکیده
In regions with a continental climate, refrigerators air-cooled condensers operate at high condensation pressures during the summer season which reduces their efficiency and accelerates wear of compressors. To reduce pressure, it was proposed to use radiative cooling is way heat removal through planet's atmosphere outer space in form infrared radiation. A refrigerating machine an assembly including air liquid connected series has been developed. temperature, pre-cooled heat-transfer agent fed condenser day hours atmospheric temperatures. At night, cooled by cooling. An experimental study operation 600 W sealed piston compressor conducted. R134a refrigerant used. Supply +33.1 °С provided reduction temperature from +47.0 +39.1 °С. The conducted +38.0 degree pressure growth decreased 30 %. refrigeration coefficient increased 11 comparison conventional scheme condenser, energy consumption system did not change daytime. offered provides stability for operation. It can be used stationary machines daytime

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Improvement of powertrain efficiency through energy breakdown analysis
A vehicular powertrain can be thought as an energy conversion chain, each component being characterized by its efficiency. Significant global efficiency improvements can be achieved once is identified the system energy breakdown, individuating the losses connected to each powertrain component; it is then possible to carry out the most appropriate interventions. This paper presents a simulation ...

Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
