An air pulse device according to the invention is used, in particular, in a heating, ventilation and/or air conditioning system of a motor vehicle. The air pulse device comprises an electric motor () having a rotor () and a stator (). The stator is mounted about a support means () such that it is in contact with said support means, the latter being made of an electrically conductive material and connected to an electrical ground. Moreover, a shield () is disposed in the vicinity of the stator, said shield also being electrically connected to the electrical ground.

An air pulse device according ding to the invention is used, in particular, in a heating, ventilation and/or air conditioning system of a motor vehicle. The air pulse device comprises a rotor () and a stator (). The stator is mounted on a support means () that projects from a metallic plate () and is electrically connected to an electrical ground. A shield () is disposed between the rotor and the stator, which shield is also electrically connected to the electrical ground.

The invention relates to heating, ventilation and/or air-conditioning equipment () including a device () for controlling the temperature of a battery () of an automobile including at least a compressor (), a condenser (), a first expansion member (), a thermal-conditioning exchanger () for exchanging heat between a coolant and a heat-transport fluid (FC), and switching means. The temperature control device () includes at least one bypass line () connecting an outlet of the compressor () to an inlet of the thermal-conditioning exchanger () while bypassing the condenser (). The invention also relates to a method for controlling the temperature of an automobile battery () implemented by means of such heating, ventilation and/or air-conditioning equipment ().

A motor for moving a flap for distributing a flow of air in a duct of a heating, ventilation and/or air conditioning installation is supplied with voltage. A power-regulation module is mounted in series with the motor, and includes at least one positive-temperature-coefficient resistor, so that, when the flap reaches an open or closed position, the motor is blocked. This results in an increase in the current strength in the circuit, causing an increase in the value of the resistance, and this results in a reduction in the current strength and in the voltage at the terminals of the motor.
