Humidity ratio- how is it measured? ( Two types) What does 1 ton refrigerator mean? Parts of refrigeration cycle? Which is the smallest component?

Question

Accepted Answer

Humidity ratio is measured using two types of instruments: psychrometers and hygrometers.

Psychrometers measure humidity ratio by comparing the readings of two thermometers: a dry-bulb and a wet-bulb thermometer.
Hygrometers measure humidity ratio using various principles such as electrical resistance, capacitance, or condensation.
A 1 ton refrigerator refers to the cooling capacity of the refrigerator, which is equivalent to removing 12,000 British Thermal Units (BTUs) of heat per hour.
The parts of a refrigeration cycle include the compressor, condenser, expansion valve, and evaporator.
The smallest component in a refrigeration cycle is typically the expansion valve, which controls the flow of refrigerant into the evaporator.
