4 results about "Greenhouse effect" patented technology

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains.

Electronic component cleaning agent

ActiveCN105754765ASurface-active non-soap compounds and soap mixture detergentsWater solubleGreenhouse effect
The invention discloses an electronic component cleaning agent. The electronic component cleaning agent comprises the following components: polyepoxysuccinic acid, alkyl polyglycoside (APG), an acid cleaning agent, secondary alkyl sodium sulfonate (SAS), hydrofluoroether, a water soluble organic amine pH value regulator, a defoaming agent, methyl epichlorohydrin, a stabilizer and an organic solvent. The invention provides a cleaning agent used for an electronic component. The cleaning agent takes hydrofluoroether with ODP of 0 as a main solvent to be matched with other components, environmental protection, low toxicity and low greenhouse effect requirements are met, the cleaning agent has good cleaning property, produces fewer foams, is non-corrosive, low in volatility, less in residue and low in viscosity and can well clean the electronic component without producing harmful effect to the electronic element.

Rapid verification method and device for non-dismountable sulfur hexafluoride density relay

ActiveCN107064787ARealize centralized verificationShorten the timeCircuit interrupters testingSulfur hexafluorideEngineering
The invention relates to a rapid verification method and device for a non-dismountable sulfur hexafluoride density relay. The device comprises first sulfur hexafluoride gas insulation equipment (1), second sulfur hexafluoride gas insulation equipment (5), a first gas sampling connector and valve (2), a second gas sampling connector and valve (6), a first density relay (3), a second density relay (7), a first density relay verification valve (4), a second density relay verification valve (8), a verification connector (9) and a rapid density relay verification platform (10). The device is advantaged in that the adjacent high-altitude sulfur hexafluoride density relays can be integrated on the platform arranged on the ground, climbing risk can be greatly reduced, all the density relays concentrated on the platform can be verified completely through a valve control method without dismounting the verification connectors, the time is substantially saved, and emission of sulfur hexafluoride gas having the greenhouse effect can be prevented.

Mixed refrigerant applicable to large-circulation temperature rise for medium-high temperature heat pump

ActiveCN102719225ALow ODPGood environmental characteristicsHeat-exchange elementsWater sourceEvaporation
The invention discloses a mixed refrigerant applicable to large-circulation temperature rise for a medium-high temperature heat pump. The mixed refrigerant comprises, by mass, 1-10% of HC1270, 2-96% of HFC134a and 3-97% of HCFC 142b. The refrigerant suitably serves as a refrigerant for a medium-high temperature heat pump system with circular temperature rise (temperature difference between evaporation and condensation) of 60-80 DEG C and the condensation temperature of 70-100 DEG C. The refrigerant is low in ozone depletion potential and greenhouse effect potential so as to meet environmental protection requirements, and is appropriate in thermal parameters and excellent in cycling performance, an HFC134a air condition compressor can be used for optimized design of a medium-high temperature heat pump unit in large-circulation temperature rise of the novel refrigerant, and the novel refrigerant can be directly applied to an original HFC134a air conditioning unit to convert the original air conditioning unit into the medium-high temperature heat pump unit in large-circulation temperature rise of the novel refrigerant. The unit can directly use normal-temperature water sources and ground sources at the temperature of about 10-40 DEG C and can provide hot water at the temperature of about 70-100 DEG C for users.
