The most critical problem in the world is to meet the energy demand, because of steadily increasing energy consumption. Refrigeration systems` electricity consumption has big portion in overall consumption. Therefore, considerable attention has been given to refrigeration capacity modulation system in order to decrease electricity consumption of these systems. Capacity modulation is used to mee...

This paper presents the analysis results of R429A, R430A, R431A and R435A as drop in substitute for R152a at various evaporating temperature with condenser temperature 30°C, 40°C and 50°C. A theoretical study of thermodynamic properties such as pressure, density, and specific volume, latent heat of vaporization compression index, and critical values are done. The theoretical performance of vapo...

1 This project is subsidized by the natural science fund of Shaanxi Province (serial number of project: 2004E210) Abstract: In this paper, according to practical consideration, a new solar powered rotary solid adsorption refrigerator system adopting activated carbon fibre + ethanol as its adsorption pair has been designed with higher performance. Moreover, the principle of the refrigeration cyc...

When designing a user interface for a simulation model there are several important issues to consider: Who is the target user group, and which a priori information can be expected. What questions do the users want answers to and what questions are answered using a specific model? When developing the user interface of EESCoolTools these issues led to a series of simulation tools each with a spec...

An efficient global cold food chain is critical to the sustainability of growing world population, and it anticipated that frozen market will reach $404.8 billion by 2027. Frozen foods are typically stored under conventional industry-standard isobaric (constant-pressure) conditions at sub-freezing temperatures, however, which can degrade textural nutritional quality comes high energetic carbon ...

OBJECTIVE The post-reconstitution chemical stability and microbial challenge hold time of nonpreserved telavancin for injection was determined using common reconstitution diluents and intravenous (IV) infusion solutions stored at room temperature with light (ambient) or at 2°C to 8°C without light (refrigeration). METHODS Telavancin was reconstituted with 5% dextrose, 0.9% normal saline, or s...
