Answer:
filter drier
Explanation:
Any refrigeration or air conditioning system needs filter driers as a crucial part. In a refrigeration or air conditioning system, a filter drier serves two crucial purposes: first, it adsorbs system impurities like water, which can produce acids, and second, it provides physical filtering. To guarantee optimal and cost-effective dryer design, each component must be evaluated. The most crucial role of a dryer is to be able to drain water from a refrigeration system. Water can originate from a variety of places, including motor windings, equipment leaks, retained air from poor drainage, and others.
In a balanced three-phase Y-Y system, the source is an abc sequence of voltages and Van 100 20° V rms. The line impedance per phase is 0.6 + j1.2 N, while the per-phase impedance of the load is 10 + j14 Q. Calculate the line currents and the load voltages.
Answer:
Explanation:
Coefficient of performance (COP) of refrigeration cycle is given by:
We are given:
COP= 5
We can also write Coefficient of performance (COP) of refrigeration cycle as:
Amount of heat absorbed by low temperature reservoir can be found as:
According to first law of thermodynamics amount of heat rejected by hot reservoir is given by:
We are given the mass of 0.96 kg. So,
Since it is a saturated liquid-vapour mixture 
.
From Refrigerant 134-a tables 
at 
is 61.3 C. (We calculated this by interpolation)
Converting from Celsius to Kelvin:
We are given:
Converting 
from Kelvin to Celsius:
From Refrigerant 134-a tables 
at 
is 356.9 KPa. (We calculated this by interpolation).
