What you need to do first is read the pressure gauges and see if the gauges read 0 psi

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.
What is meant by restricting liquid refrigerant into a refrigeration system when charging?
Vaporizing the refrigerant
Why is refrigerant vapor re introduced to the refrigeration system before refrigerant liquid?
To endure that the ONLY gas in the system is refrigerant.

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
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.
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

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.
How does a split air conditioner work?
All refrigeration cycles operate on the theory of changing states of a refrigerant to remove and reject heat. To remove heat, liquid refrigerant is exposed to the air passing through the evaporator, the removed heat causes the liquid refrigerant to boil, or change state liquid to a vapor, consequently, the heat is rejected by removing heat and condensing the vapor back to a liquid.
What is the function of liquid receiver in a refrigeration system?
Liquid receivers are used to store the liquid refrigerant after it leaves the condenser. It should be located below the condenser to enable natural flow. The receiver may be constructed either vertically or horizontally and should have sufficient capacity to hold the entire system's refrigerant charge. The design should be such that only liquid refrigerant leaves the receiver and enters the liquid line. by vishal mahnn
