The compressor, condenser, expansion valve/throttle valve, and evaporator are the four elements that make up the vapor compression cycle.
The main difficulties in vapor compression refrigeration system miniaturization for designs based on standard-scale systems have to do with component integration and miniaturization.
The most important aspect of all mechanical refrigeration systems is the creation of a compact yet effective gas compressor.
The first factor is connected to the most basic separation mechanism that comes to mind: gravity. The maximum vapor velocity that is permitted should be determined by looking at the terminal velocity of the droplets if gravity settling is to be employed as a separation technique. This will prevent the droplets from being swept away with the vapor.

I am pretty sure it's four. I looked it up, and I have a book I just looked through. Sorry if it's wrong! Have a good rest of 2016!
Yes it is correct and true hope it helps
<u>Answer:</u>
The academic achievement of students with hearing loss is relatively low compared with that of students with no disabilities.
Option: (c)
<u>Explanation:</u>
- Several studies were carried out to compare the "academic achievement" of students with hearing disability and the reports showed that the disabled students scored relatively low compared to the students with no disability.
- There was adverse effect on academic areas like learning, math, writing, etc. Also, the problem of higher absenteeism and higher dropout rate was faced along with lower GPA and SAT score.
- The students with disability also took one semester longer to complete the semester.
