What is the correct pressure on the high side and the low side of an efficiently working system?
High side <200psi. Low side <50 lb.
"A good rule of thumb with R134a is to run fan on High with all windows open and engine at 1500 rpm. High side pressure in PSI should be about 2.2 to 2.5 times outside air temperature in degrees F"
I, myself, am not trolling for customers or to gratify my superiority, unlike some others.
There are NO easy answers to this. Most manufacturers provide a chart or charts that will assist in determining what those pressures will be. The variables that will affect those pressures include, but are not limited to: Outdoor ambient temperature Outdoor relative humidity Indoor entering temperature (wet bulb or dry, depending on rel. humidity) Unit and duct sizing and proper airflow through system Some techs will use "rules of thumb" and dead reckoning that may have worked in the good old days, but with ever rising costs, newer systems are more demanding and a simple refrigerant miscalculation could cause performance problems resulting in comfort concerns or higher power bills. If this is true, then why do the gauges you use have a chart on them that tells what the high side range and low side range should be? Also, if this is such a cryptic answer, then why can I buy these gauges at a tool store for about $20? The low side should be anywhere from 65-80 psi (40 degree coil temp) The high side should correlate with the outside temp... The gauges have pressure temp for each type of freon being used,for example using R-22 freon on a outside ac unit,40 degrees will equal to 70 psi on the gauges (suction/low side) gauge Sure, you can buy guages at a tool store. I fix a lot of repairs made by do it yourselfers. The chart on the guages are for corresponding pressure to temperature, not to tell you how much gas to put in. The best, most comprehensive measurement is superheat: suction pressure converted to temperature and a measurement of suction line temperature. this tells you how the refrigerant is acting in regards to the total (sensible and latent) amount of heat it is removing from the air.

How do you reset the tire pressure warning light on a 2008 dodge Caliber?
The light will reset itself if the system is working properly and the tires are at the correct pressure. If the pressure is correct and the light is still on, you need to take it in for service.
How can I adjust the pump pressure switch to optimize the performance of my system?
To adjust the pump pressure switch for optimal system performance, locate the switch on the pump and use a screwdriver to adjust the pressure setting. Increase the pressure if the system is not working efficiently, and decrease it if there are issues with overpressure. Test the system after each adjustment to ensure it is functioning properly.
Design pressure compare to working pressure?
Design pressure is the maximum pressure a system is designed to withstand, while working pressure is the pressure at which a system operates during normal conditions. Design pressure accounts for safety factors and potential overpressure situations, while working pressure represents the typical operating conditions of the system. It is important for the design pressure to be higher than the working pressure to ensure the system can handle occasional pressure spikes or other abnormal conditions.
What is the impact of natural gas pressure on the efficiency of a gas-powered heating system?
The impact of natural gas pressure on the efficiency of a gas-powered heating system is significant. Proper gas pressure ensures that the system burns fuel efficiently, providing consistent and reliable heat. Low pressure can lead to incomplete combustion, reduced heat output, and potential safety hazards. High pressure can also cause inefficiencies and damage to the system. Maintaining the correct gas pressure is crucial for optimal performance and energy efficiency.
When pressurizing a system do not exceed?
The rated working pressure of the equipment.
What is the purpose of a pressure vacuum breaker in a sprinkler system and how does it help to maintain the correct pressure levels?
A pressure vacuum breaker in a sprinkler system is designed to prevent backflow of contaminated water into the system. It helps maintain correct pressure levels by allowing air to enter the system when there is a drop in pressure, preventing the water from flowing backwards and potentially contaminating the water supply.
What is the importance of a pressure relief valve for a well pump system and how does it function to maintain optimal pressure levels?
A pressure relief valve is important for a well pump system because it helps prevent over-pressurization, which can damage the system. It functions by opening when the pressure exceeds a certain level, releasing excess pressure and maintaining optimal pressure levels to ensure the system operates safely and efficiently.
What is the purpose of a water heater pressure regulator and how does it help maintain the optimal pressure in a water heater system?
The purpose of a water heater pressure regulator is to control and maintain the pressure within a water heater system. It helps prevent the pressure from getting too high, which can lead to damage or leaks in the system. By regulating the pressure, the regulator ensures that the water heater functions properly and efficiently.
What low pressure switch do for pontiaccMontana 2004?
The low pressure switch in a 2004 Pontiac Montana is responsible for monitoring the pressure of the air conditioning system. If the pressure drops below a certain level, the switch will trigger the compressor to shut off to prevent damage to the system. It helps ensure that the AC system operates safely and efficiently.
What is the difference between the terms burst pressure and working pressure?
Working pressure refers to the maximum safe *operating* pressure. Burst pressure refers to the actual point at which the vessel containing said pressure will fail. Operating pressures normally have a "buffer zone" between itself and burst pressure, to insure no sudden spikes or variations cause failure leading to injury.
Does a refrigerant in a refrigeration system is changes state in the condenser and evaporator?
Yes, in a refrigeration system, the refrigerant changes state from a high-pressure gas to a high-pressure liquid in the condenser, and then from a low-pressure liquid to a low-pressure gas in the evaporator. These state changes are crucial for the refrigeration cycle to operate efficiently.
What is the maximum pressure capacity of the hydraulic system, measured in pounds per square inch (psi), required to operate the heavy-duty machinery efficiently and safely at 4000 psi?
The maximum pressure capacity of the hydraulic system needed to operate heavy-duty machinery efficiently and safely is 4000 pounds per square inch (psi).
