What is a reason to obtain an accurate pressure reading of refrigerant inside a recovery cylinder?
Damaged refrigerant
What role does a compessor play in a refrigeration system?
In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
When using recovery our recycling equipment manufactured before November 15 1993 technicians must evacuate low-pressure appliances to what level before making a major repair?
Technicians must evacuate low-pressure appliances to a vacuum level of 0 inches of mercury (inHg) before making a major repair on recovery and recycling equipment manufactured before November 15, 1993. This ensures that any refrigerants are adequately removed from the system, minimizing the risk of release into the atmosphere during repairs. Proper evacuation is essential for compliance with environmental regulations and safe handling of refrigerants.
What causes refrigerant side of water cooled chiller to have excessive suction and discharge pressure though tubes are clean?
Goldfish. They get in at night, have underwater cocktail parties and leave the ice floating about.

What is the pressure and temperaure of domestic refrigerator when charging R-134a refigerant?
Generally you charge a refrigeration system by weight, not by pressure or temperature. Say, for example, if you were adding refrigerant to a system, you might add a pound of refrigerant. You wouldn't add it until it was at a certain pressure. As for a consumer AC system in a vehicle, I couldn't tell you how much to add. Look for a reference of the amount of refrigerant in the system and start by adding half that amount maybe?
How do you change high temperature refrigerant and high pressure refrigerant in to low temperature refrigerant and low pressure refrigerant?
You cool it and run it through a metering devise.
What determines the temperature at which a refrigerant vaporizes?
The pressure and the specific refrigerant properties determine the temperature at which a refrigerant vaporizes. As pressure increases, the boiling point of the refrigerant also increases. Different refrigerants have different boiling points at different pressures.
The function of the condenser is too increase refrigeration pressure lose the heat from the refrigerant add heat to the refrigerant reduce the fridge aration pressure?
The function of the condenser is to release heat from the refrigerant, causing it to condense from a gas to a liquid state. This process increases the pressure of the refrigerant.
What happens when refrigerant enters the condenser?
what happens when refrigerant enters the condenser
When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?
Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
Refrigerant pressure decreases in a refrigerant cylinder while charging with vapor because vapor has a lower density compared to liquid refrigerant. As vapor is introduced into the cylinder, it displaces the liquid refrigerant, causing the pressure to drop as the overall density of the refrigerant in the cylinder decreases.
How is the refrigerant cylinder pressure kept above the system pressure when charging with vapor from a cylinder?
The refrigerant cylinder pressure is typically higher than the system pressure, which allows the refrigerant to flow from the cylinder into the system. By opening the valve on the refrigerant cylinder, the higher pressure inside the cylinder forces the vapor refrigerant into the lower pressure system. This creates a flow of refrigerant into the system until the pressures equalize or until the desired amount of refrigerant has been added.
Which refrigerant is considered high or very high pressure refrigerant?
r 134-a
