How does a climate control actuator work in a car?

They also control hot and cold settings for right and left passenger compartments. Your car’s climate control computer gives an electrical command to the actuator to start moving the actuator motor to change air direction modes. This direction is according to the temperature chosen by the driver or passenger on dual climate control systems.

How are temperature actuators used in a heater?

Temperature actuators blend the cooled air with warm air to achieve the temperature we want. They do this by allowing some air to flow through the heater core, after flowing through the evaporator core. The dual-zone system adds more actuators and doors.

How are actuators used in dual zone systems?

Dual zone system may have two or more blend actuators. The fresh/circulate actuator controls inside and outside air used in the system. Sometimes also called fresh air re-circulate. A Heater control actuator can control heater flow. On some systems this is controlled by the mode actuator.

Where are the actuators located on a car?

This direction is according to the temperature chosen by the driver or passenger on dual climate control systems. Most systems have three to four of these units placed in various areas around the HVAC plenum that control mode operation and will vary by the car make and model.

How are actuators control vehicle mode and temperature?

How actuators control vehicle mode and temperature. A plastic case under the dash contains the air conditioner evaporator-core and the heater core . Air flows through the case and a series of doors that the actuators open and close to control this flow. The position of the doors determines where air flows and the temperature.

What is THERMOTRONIC automatic climate control?

The THERMOTRONIC automatic climate control automatically ensures a constant feel-good climate in the cab, even in direct sunlight or in very high or very low outside temperatures. Here the temperature, the ventilation intensity and the air distribution are regulated via sensors according to the presettings and continuously adapted to the

What is a temperature door actuator?

A temperature actuator is any device that turns equipment on and off in response to temperature changes. They may use a variety of methods to measure temperature changes, including metals, chemicals or gases.
