What is the ideal fan speed in AC?
Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home more effectively and remove more moisture from the air because of slower air movement through the cooling equipment.
How cold should AC be at idle?
With temperatures well into the 80’s Fahrenheit, the outlet temperature should be around 35 to 45 degrees. This temperature should not change much when the engine is brought back to idle.
Is it OK to run air conditioner continuously?
The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today. This is why in some cases, this constant running can be dangerous. The freezing of the coil can cause liquid refrigerant to flood back into the unit’s compressor and damage it.
How cold should vehicle AC be?
The auto A/C is in good working order. If the ambient air temperature is 70 degrees Fahrenheit and the humidity is 20%, the outlet air temperature should be between 35 and 40 degrees.
Why does my car idle when the AC is on?
It also helps increase engine speed when an extra load is placed on the engine, for example, when you turn on the AC or defrost system. However, a faulty or restricted IAC valve may keep the engine idle speed from increasing when it needs to.
What is the idle air control actuator used for?
(July 2018) An idle air control actuator or idle air control valve (IAC actuator/valve) is a device commonly used in fuel-injected vehicles to control the engine’s idling rotational speed (RPM). In carburetted vehicles a similar device known as an idle speed control actuator is used.
Are there any myths about an engine cooling system?
There are many myths and misconceptions about engine cooling, but the truth is your engine’s cooling system must perform a balancing act. It needs to extract enough heat to keep your engine happy, yet maintain enough heat to keep it operating efficiently.
What happens when air moves too fast in a cooling system?
When air is moving too fast, you get into boundary layer issues where heat doesn’t get carried away because air isn’t actually touching fins and tubes. You want air to move slowly enough across fins and tubes to where it carries heat away.
