Minimal air conditioning. The thermostat monitors the temperature of the air. Its simplicity makes it a good example for describing how an analog thermostat works. That's why they call it air conditioning. It should be set to AUTO, which means the blower will only blow air out the vents when the air conditioning or furnace cools and heats the air respectively. 50" fan is about 189 sq. There are a lot of factors that determine whether your compressor will turn on, including blockages and problems with the thermostat that may prevent the compressor. One of them is when a miscalibration in the thermostat leads to a short-cycling AC. When you first start the car it should be closed, essentially blocking the water/coolant from traversing the radiator thus allowing the engine to reach its optimum temperature as quickly as possible. I would suggest that you check the “O” orange wire (orange usually) to common with a volt meter and see if you are getting 24 to 28 volts AC to the reversing valve solenoid when your heat pump is in the cooling mode. If a thermostat was stuck closed, there would be no flow even after the engine reached the operating temperature, and the lower radiator hose would remain cool. The first modern air conditioning system was developed in 1902 by a young electrical engineer named Willis Haviland Carrier.
