Climate control system fan

Abstract

The invention relates to a fan blower (18) for a heating / air conditioning system, in particular for a motor vehicle, with an impeller (22) and a motor (24) that drives this impeller (22). The invention provides that at least one ion generator (48) is structurally connected to the fan blower (18). The invention relates, in particular, to a fan blower (18) of the aforementioned type in which the ionizer (48) is connected to the fan blower electronics (58) or is integrated therein. The invention additionally relates to a heating / air conditioning system provided with at least one evaporator (20), at least one heating heat-exchanger (28), at least one fan blower (18), and an electronic circuit (58) that controls the fan blower (18). The invention provides that, in a heating / air conditioning system of this type, at least one ion generator (48) is structurally connected to the fan blower (18) and / or the electronic circuit (58) of the fan blower (18) of the heating / air conditioning system.

Description

[0001] The present invention relates to a fan blower for a heating / air conditioning system, in particular for a motor vehicle. A fan blower of this type has an impeller and an electric motor that drives this impeller, and it is typically located in the heater housing assembly of a motor vehicle.BACKGROUND INFORMATION[0002] Luxury-class motor vehicles and, increasingly, moderate-class motor vehicles are equipped not only with a heating system, but, as of recently, also with an air conditioning system as a standard feature. A heating / air conditioning system of this type generally includes at least one evaporator, at least one heating heat-exchanger, and a fan blower. When air is cooled as part of the air-conditioning process, it is very often dehumidified as well. When this occurs, the moisture in the air condenses on cold surfaces. Although most of the liquid condensate is drained off over time, a certain liquid film remains on the surfaces. As a result, the continual precipitation o...

AI Technical Summary

Benefits of technology

The invention is a fan blower for a heating / air conditioning system of a motor vehicle that includes an ion generator to eliminate or deactivate odor-producing deposits. The fan blower is structurally connected to the ion generator, which ensures that the ions are mixed well with the air. This results in a good mixing of air with the ions, which deactivates the biological material that causes odor. The ion generator can be located after the fresh air-recirculated air mode door, in front of the evaporator, or in the same housing as the fan blower electronics. The use of the fan blower with the ion generator results in a reduction of odor problems in the air conditioning system of the motor vehicle and is advantageous in terms of installation space, weight, and component outlay.

Problems solved by technology

When air is cooled as part of the air-conditioning process, it is very often dehumidified as well.

As a result, the continual precipitation of moisture out of the supplied air tends to cause fungal deposits and bacterial cultures to develop on evaporators in motor vehicle air-conditioning systems, for example, due to contaminants in the transported air.

The products of decomposition of these bacteria create odor problems and pose health risks, such as allergies, to the motor vehicle passengers.

Although these measures reduce deposits and the formation of odor associated therewith, they cannot be eliminated entirely, in particular as the air conditioning system ages.
