What is meant by restricting liquid refrigeration system when charging?
Vaporizing the Refrigerant
What component is closed during charging to prevent the flow of refrigerant to the low-pressure side of the refrigeration system?
The King valve is closed, starving the low pressure side, creating more vacuum while charging with a liquid
The device in a refrigeration system that causes the refrigerant to go from a liquid to a gas is the?
Condensor
What is the device in a refrigeration system that causes the refrigerant to go from a liquid to a gas is the?
orifice
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.

How is liquid refrigerant added to the refrigeration system when the system is out of refrigeration?
Liquid refrigerant charging of a system is normally accomplished in the liquid line. For example, when a system is out of refrigerant, liquid refrigerant can be charged into the king valve on the liquid line or receiver.

Why is refrigerant vapor re introduced to the refrigeration system before refrigerant liquid?
To endure that the ONLY gas in the system is refrigerant.

Condensor

How do you determine when enough vapor has entered the refrigeration system before you charge refrigerant liquid?
When the refrigerant saturation temperature increases to 36 degrees F.
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.
Define flash gas and how it applies to the net refrigeration effects of the refrigeration cycle?
FLASH GAS - Instantaneous evaporation of some liquid refrigerant at the metering device due to pressure drop which cools the remaining liquid refrigerant to desired evaporation temperature.This flash gas cannot absorb any heat having a negative effect on the net refrigeration cycle

When recharging a refrigeration system with R-11 what vapor pressure is necessary in the shells before charging with liquid?
21.1" vacuum
What is cryogenic refrigeration?
Cryogenic refrigeration is refrigeration which uses freezing mixtures such as dry ice, soilid co2, liquid co2, or liquid nitrogen. In the liquid co2 or liquid nitrogen method, a compartment is fitted with a temperature sensing element that can be preset. This is in turn connected to a control panel which activates liquid co2 or liquid nitrogen cylinder fitted with regulators to release the refrigerant. This is delivered through a spray header into the compartment until the desired temperature is achieved.
