What is the evaporator coil to air relationship when the compressor is not running?
When the compressor is not running, the evaporator coil absorbs heat from the indoor air, causing the refrigerant inside the coil to evaporate and turn into a low-pressure gas. This process helps cool the air circulating through the HVAC system before it is distributed back into the living space.

Is suction pressure another word for evaporator saturation pressure?
No, suction pressure refers to the pressure of refrigerant gas leaving the evaporator and entering the compressor, while evaporator saturation pressure refers to the pressure at which a refrigerant changes from a liquid to a vapor in the evaporator coil. They are related but not the same.
If 3000 ft3 of air is crossing an evaporator coil and is cooled from 75 degree Fahrenheit to 55 degree Fahrenheit what would be the volume of air in ft3 exiting the evaporator coil?
Assuming the air behaves ideally, there is no change in the volume of air passing through the evaporator coil during the cooling process. Therefore, the volume of air exiting the evaporator coil would also be 3000 ft3.
Why do we need to insulate evaporator?
Insulating the evaporator coil helps to prevent condensation from forming on the coil. This can improve the efficiency of the cooling process by keeping the coil dry and preventing energy loss due to heat transfer. Additionally, insulating the evaporator can help prevent moisture damage to surrounding components.
How does a thermostatic expansion valve operate in a heat pump system?
A thermostatic expansion valve in a heat pump system controls the flow of refrigerant entering the evaporator coil based on the temperature and pressure of the refrigerant exiting the coil. It maintains a constant superheat at the evaporator outlet to ensure optimal efficiency and performance by adjusting the size of the refrigerant opening. This helps regulate the cooling capacity of the system and prevents liquid refrigerant from entering the compressor.
What is the expected temperature drop through a direct expansion evaporator coil is?
The expected temperature drop through a direct expansion evaporator coil is typically around 15 to 20 degrees Fahrenheit. This drop in temperature occurs as the refrigerant evaporates and absorbs heat from the air passing over the coil. It is important for efficient cooling and dehumidification in an HVAC system.
What does a condeser to in refrigeration?
Rejects the heat from the compressor and cold coil (evaporator).
A clogged or dirty evaporator coil can?
-reduce efficiency of your unit,and increase pressure ratio of the compressor,-
Electrical parts of refrigeration and air conditioning?

My Central air conditioner is making a louder humming noise then usual and is not blowing cold air It was working in the morning then stopped blowing cold and got noisey in the afternoon help and ty?
check and see if evaporator coil restricted, coil frozen, if not check pressures sounds like unit running but not shutting down, if coil frozen oil may be carried from compressor and leaving compressor with no lubrication repair before burning out compressor.
What is the proper sized compressor to match up to a Bryant AC evaporator coil ck5bxw030017aaaa?
Two And A Half Tons OR 30,000 BTU's
Evaporator line from the compressor is freezing then it thaws and water goes on floor?
Sounds like the coil is dirty. Have it checked by a air conditioning company.
What is the difference between split and window Aircondition?
A window a/c is a self-contained unit. The condensor, evaporator and compressor are all in the unit. A split system is the common central air unit you see on most homes. The evaporator coil is located at the furnace withe the system fan, while the compressor and condensing coil are outside the house. This is a simple explaination, but I .
Is suction pressure another word for evaporator saturation pressure?
No, suction pressure refers to the pressure of refrigerant gas leaving the evaporator and entering the compressor, while evaporator saturation pressure refers to the pressure at which a refrigerant changes from a liquid to a vapor in the evaporator coil. They are related but not the same.
Why is your refrigerator blowing warm air?
Your compressor is not working. Through evaporation compressors cool the evaporator coil and the fan blows air across it. So if the fan is blowing hot air the compressor is not cooling the coil. But check to see if the dial inside the fridge is turned to "more cold" , that turns the compressor on.
Can you install a 3.5 ton condenser on a 3 ton evaporator?
Installing a 3 1/2 ton condenser on a 3 tr evaporator will not function properly. There isn't enough evaporator coil surface area to absorb heat and vaporize refrigerant liquid for its return back to the condenser compressor. What can be done is a 3 ton condenser unit with a 3 1/2 evaporator coil.
What is commonly used to defrost the ice from the a low temperature evaporator?
Hot gas from the discharge line of the compressor is routed into the evaporator or electric heating elements are embedded into the evaporator fins. Hot gas is often more efficient because no outside power source is needed to defrost the evaporator coil.
How does the air handler evaporator coil contribute to the overall efficiency of an HVAC system?
The air handler evaporator coil helps cool and dehumidify the air in an HVAC system. By absorbing heat from the air and transferring it to the refrigerant, the coil helps the system operate more efficiently by reducing the workload on the compressor and improving overall energy efficiency.
