<p><div><p>Today we Auto Ac Condenser manufacturers come to summarize the Control method of cooling fan for automobile air conditioner condenser.There are several ways to control the cooling fan of a car air conditioner condenser:1. A/C switch direct control type1-Condenser fan 2-Condenser fan relay 3-Electromagnetic clutch 4-temperature controller 5-connected A/C switch2.</p><br><img src="//img.yfisher.com/1607675656221.jpg" style="margin:10px auto"><br><p> A/C switch and water temperature switch combined control type1) When the air conditioner is not workingThe operation of the fan depends on the engine water temperature.2) When working in air conditioningThe water temperature control circuit is still functioning, at which time the cooling fan is controlled by both the air conditioning and the water temperature control loop.The operation of the two cooling fans is affected by the water temperature and the air conditioning signal at the same time, while at the same time not rotating, while the low speed or high-speed rotation between the three states.</p><p> 3. Water temperature sensor and refrigerant pressure switch control typeIt is jointly controlled based on the air conditioning signal and the water temperature signal.Working process: TEMP1, when the water tank cooling water temperature is higher than the range, the control unit will open VT1 and make the water tank fan and the condenser fan run.</p><p>TEMP2, when the tank cooling water temperature is higher than this range, the control unit will open VT2 and make the tank fan and condenser fan operate. TEMP3, when the water tank cooling water temperature is higher than the range, the control unit will turn off VT3 and stop the air conditioner compressor.4.</p><p> Refrigerant pressure switch and microcomputer control combinationThe two radiator fans have three different operating conditions:1) The air conditioner switch is turned on, but when the refrigerant pressure does not reach 1.81PA, only the auxiliary cooling fan motor operates. 2) Once the refrigerant pressure reaches 1.</p><br><img src="//img.yfisher.com/1608813348406.jpg" style="margin:10px auto"><br><p>81MPA, the main and auxiliary fan motors run simultaneously.3) Regardless of whether the air conditioner switch is turned on or not, as long as the engine water temperature reaches 98 degrees or more, the main cooling fan runs at a high speed.
