Dielectric strength is a measure of the electrical insulation capability of a substance. When a refrigerant becomes contaminated with moisture or other impurities, it can lower its dielectric strength.

The specific volume of a refrigerant refers to the volume occupied by a unit mass of the refrigerant. It is inversely proportional to the density of the refrigerant.

The higher the specific volume of the refrigerant lower will be the density of the refrigerant and takes up more space. In order to move a larger volume of refrigerant per unit of time, the compressor needs to have a higher compressor displacement (volume swept by the compressor piston or rotating components per unit of time).

Yes, most refrigerants used in refrigeration systems are typically hydrophobic (low affinity for water). They are designed to have low water solubility to prevent the absorption of moisture from the environment or the formation of water-based solutions within the refrigeration system. The presence of moisture in refrigerant may lead to reduced efficiency, the formation of acids resulting in corrosion, degradation of lubricants, ice formation and damage of compressor and other components

R-410A is an HFC refrigerant and is zeotropic refrigerant blend composed of approximately equal parts R-32 (difluoromethane) and R-125 (pentafluoroethane)

In push-pull recovery, a recovery unit is used to create a vacuum in the refrigeration system. This vacuum pulls the refrigerant out of the system and into the recovery cylinder.

Result in acid formation which can cause corrosion

This is to prevent the cylinder from rupturing if the refrigerant expands due to an increase in temperature

The critical pressure of a refrigerant is the pressure at which the refrigerant can no longer be liquefied by increasing the pressure. A higher critical pressure means that the refrigerant can be liquefied at a higher temperature, which is desirable for refrigeration systems.

Class A refrigerants are refrigerants for which toxicity has not been identified at concentrations of less than or equal to 400 parts per million (PPM) by volume. Examples of Class A refrigerant are: R-134a, R-410A, R-407C

The latent heat of vaporization is the amount of heat required to change a liquid into a gas. The higher the molecular weight of a substance, the stronger the intermolecular forces between its molecules. This makes it more difficult for the molecules to escape from the liquid state and become a gas.

R-22 has a lower boiling point than R-11 and R-12. A lower boiling point means that the refrigerant will vaporize at a lower temperature. This is desirable for some applications, such as air conditioning, because it allows the refrigerant to absorb heat from the air at a lower temperature.

Specific volume is the volume of a unit mass of a substance. It is the reciprocal of density.

The amount of heat required to change the refrigerant from a liquid to a gas is called the latent heat of vaporization. The higher the latent heat of vaporization, the more heat can be removed from the air.

The latent heat of vaporization of a refrigerant is the amount of heat that is absorbed by the refrigerant when it vaporizes. The higher the latent heat of vaporization, the more heat can be removed from the air by the refrigerant.
