Problems solved by technology

But this tiny fiber diameter and increased surface density of nonwovens lead to an increase in filter ventilation resistance
[0008] There is a strong need to reduce the weight and size of the HVAC unit of the vehicle air conditioner, and the increase in the ventilation resistance of the filter makes it difficult to obtain the air flow required for air conditioning
In addition, the clogging of the non-woven fabric during use leads to an increase in the ventilation resistance of the filter, which deteriorates the air conditioning performance of the vehicle air conditioner
[0009] It should be noted that although ions are known to have the effect of making the driver feel better and removing bacteria and odors from the air in the passenger compartment, it is not known whether ions are effective at removing airborne particulates if certain conditions are encountered

[0057] 1. Example A, B and Comparative Example A, B

[0058] Figure 5 is a graph showing the relationship between ion concentration and airborne particle removal efficiency.

[0059] For Example A and Comparative Example A, use such as Figure 6 The test setup shown was used for the measurements. The test device consists of 1m 3 The volume of the acrylic chamber 44, and the ion generator 40 is placed in the chamber 44. Ion generator 40 may control the amount of ions generated, thereby controlling the concentration of ions within chamber 44 .

[0060] For the chamber 44, two blowers 46 for circulating the air in the chamber 44, an ion counter tube (produced by ANDES Electric Co., Ltd.) for counting the number of ions in the chamber 44 are installed. ITC-210A), and a particle counter tube (KC-01A produced by RION Co., Ltd.) for counting the number of suspended particles in the air in the chamber 44 .

[0061] The test temperature is between 20° and 25°, and the airflow fo...

Abstract

An automotive air conditioner has an ionizer (40). The automotive air conditioner supplies ions generated by the ionizer (40) into a passenger compartment (6) to create an average ion concentration of 5000 ions per cc of higher in the passenger compartment (6).

Description

technical field [0001] The present invention relates to a vehicle air conditioner with an ionizer. Background technique [0002] Certain vehicle air conditioners have an HVAC (Heating Ventilation Air Conditioning) unit placed in the dashboard in front of the passenger compartment of the vehicle. An air passage is defined partially within the housing of the HVAC unit through which conditioned air is delivered into the passenger compartment. [0003] More specifically, within the housing of the HVAC unit, a blower and an evaporator are housed. The blower creates an airflow from the air inlet to the air outlet of the HVAC, and the evaporator cools the air passing through the evaporator. In the HVAC unit housing, upstream of the blower, a filter made of non-woven fabric or the like is provided. Filters remove dust from the airflow. [0004] Air ducts extend from respective air outlets. The air ducts have outlets to the passenger compartment, such as defroster air ports dire...
