Commercial refrigeration systems consumed 1.21 Quads of primary energy in 2010 and are known to be a major source for refrigerant charge leakage into the environment. Thus, it is important to study the environmental impact of commercial supermarket refrigeration systems and improve their design to minimize any adverse impacts. The system's Life Cycle Climate Performance (LCCP) was presented as ...
We tested various thymidine analogues for induction of a senescence-like phenomenon in HeLa cells. CldU, BrdU, and IdU similarly induced the morphology of senescent cells and typical senescence markers. Thymidine analogues other than 5-halogenated forms caused only cell death. BrdU efficiently killed the cells in cooperation with irradiation with light and a brief treatment with Hoechst 33258, ...
An assessment has been made of the potential for toxic effects to aquatic life that may arise from halogenated organic by-products formed by reaction of hypochlorite with organic matter in various use scenarios as a contribution to the risk assessment of sodium hypochlorite under the European Union Existing Chemicals legislation. In the study, samples that would represent worst-case models for ...
In recent years the household compressor manufacturers have reduced the energy losses inside the compressors resulting in a positive effect on the energy consumption in the cabinets. In the following, N-butane, which is a natural and non ozone depletion refrigerant, is compared to refrigerants presently used in household compressors.
We use standard thermodynamic relationships to demonstrate the accuracy of new vapor pressure measurements by using them in the calculation ofliquid-phase heat capacities and comparing the results with recently published experimental values. Results for the new alternative refrigerants Rl34a and R 123 are used as examples.
This paper presents the improvement of eco-friendly and power consumption saving refrigerants for refrigeration systems. The novel azeotropic refrigerant mixtures HFCs HCs can replace systems, using R134, R32, R125, R1270 in several compositions found decision tree function RapidMiner software (which came first KDnuggets annual poll). All results are mixed POE, which is A1 classification refrig...
