In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. In this research paper, the ...

This paper presents the variation law of temperature in three-dimensional space, which is cooled by the refrigeration provided by the cold side of a semiconductor. The mathematical model of the temperature field of the semiconductor refrigeration device is described, and a numerical study on the temperature profile in a semiconductor refrigeration device was carried out using this model. The pr...

The magnetic and magnetocaloric properties of Ni48Co2Mn35In15 were studied using magnetization and heat capacity measurements. The magnetic entropy change (DSM) was evaluated from both magnetizing and demagnetizing fields. An inverse DSM for the magnetizing and demagnetizing processes were found to be 20.5 and 18.5 J kg!1 K!1, respectively, for DH1⁄4 5 T at the martensitic transition (T1⁄4 TM)....

Aberrant false-positive reactions in negative-controls during ELISA testing for Clostridium difficile indicated the potential for false-diagnoses. Experiments with 96-well products showed a maximum peak of false-positive immunoassay reactions with the provided negative-control reagents after 5 refrigeration-to-room temperature cycles (P < 0.001), decreasing thereafter with additional refrigerat...

This paper deals with open-shaft twin-screw refrigeration compressors in the 10 175 m3/h (10 100 CFM) range. Applications for such compressors are, for example,external combustion engine heat-pumps and transport refrigeration. The twin-screw compressor concept is discussed from following view-points; operational mode and rotor housing design drive arrangement bearings lubricants cooling volume ...

This study presents a thermodynamic analysis of new combined power/refrigeration cycle. The cycle is comprised two innovative cycles: Kalina (KNC) and ejector refrigeration (ERC) for power production, respectively. Recovery heat process involved in the design to rise energetic exergetic efficiencies: emitted by KNC absorbed ERC order generate cooling. Effects variation operational conditions wh...

background: spinach is one of the vegetables with a high concentration of nitrate which is affected by various processes such as cooking and refrigeration before consumption. the present study aimed to investigate the effect of home cooking method, which has not been studied before, on the level of nitrate and nitrite in spinach. the effect of refrigeration was studied, as well.   methods: afte...
