Description
Technical field
The invention belongs to motorcar air conditioner manufacturing technology field, specially refer to a kind of device and control method thereof that prevents that automobile air-conditioning evaporator from going mouldy.
Background technology
Summer is when using air-conditioning; Surface at evaporimeter can form a large amount of condensed waters; HVAC (Heating, Ventilation and Air Conditioning, i.e. heating ventilation and air conditioning) assembly has drainage arrangement; But the globule that condenses in evaporator surface but can not discharge fully timely, also has the surface that many condensed waters remain on evaporimeter after air-conditioning is closed.Because summer temperature is higher, and interior space is narrow and small, and evaporator surface also has a spot of dust impurity etc., evaporator surface very easily goes mouldy simultaneously.In case evaporimeter goes mouldy, will produce a large amount of bacteriums and peculiar smell, have a strong impact on passenger's health and comfort level.Traditional way is that evaporator surface is done hydrophilic treatment; To strengthen the drainability of evaporator surface; This method can reduce the condensed water of evaporator surface to a certain extent, but can not make the evaporator surface bone dry, therefore also just can not avoid evaporimeter to go mouldy.
Summary of the invention
The objective of the invention is to propose a kind of device and control method thereof that prevents that automobile air-conditioning evaporator from going mouldy, go mouldy, thereby improve the air ambient in the car, improve comfort level to avoid evaporimeter.
The device that prevents that automobile air-conditioning evaporator from going mouldy of the present invention comprises the controller of air-conditioning and receives the air conditioner blower of said controller control; Key is also to comprise a humidity sensor that is installed in the automobile air-conditioning evaporator, and said humidity sensor links to each other with the controller of air-conditioning.
After the above-mentioned control method that prevents the device that automobile air-conditioning evaporator goes mouldy comprises the steps: that controller cuts out compressor of air conditioner; Controller utilizes humidity sensor to survey the humidity of evaporator surface; When the humidity of evaporator surface is higher than first predetermined moisture; Controller control air blast works on, and is lower than second predetermined moisture up to the humidity of evaporator surface, and said first predetermined moisture is greater than second predetermined moisture.
After air-conditioning is closed, prolong the working time of air blast, can dry up the condensed water that evaporator surface gathers, it is kept dry, go mouldy to avoid evaporimeter.
Further, the above-mentioned device that prevents that automobile air-conditioning evaporator from going mouldy also comprises a temperature sensor that is installed in the automobile air-conditioning evaporator, and said temperature sensor links to each other with the controller of air-conditioning.
After the above-mentioned control method that prevents the device that automobile air-conditioning evaporator goes mouldy comprises the steps: that controller cuts out compressor of air conditioner; Controller utilizes humidity sensor to survey the humidity of evaporator surface, utilizes temperature sensor to survey the temperature of evaporator surface simultaneously; When the temperature of evaporator surface was lower than first predetermined temperature and humidity and is higher than first predetermined moisture, controller control air blast worked on, and the temperature that is lower than second predetermined moisture or evaporator surface up to the humidity of evaporator surface is higher than second predetermined temperature; Said first predetermined moisture is greater than second predetermined moisture, and second predetermined temperature is higher than first predetermined temperature.
Above-mentioned device and the control method thereof that prevents that automobile air-conditioning evaporator from going mouldy considered the influence of evaporator surface temperature to going mouldy; Temperature is high more, and condensed water is just high more by the possibility of natural evaporation, and the possibility that evaporimeter goes mouldy is just more little; Therefore survey the temperature of evaporator surface through temperature sensor; And the control air blast lengthens working hours, and all is in desirable level, the possibility that can thoroughly avoid evaporimeter to go mouldy up to the temperature and humidity of evaporator surface.
Specifically, above-mentioned first predetermined moisture is that 90%, the second predetermined moisture is 60%; Said first predetermined temperature is 2 ℃, and second predetermined temperature is 10 ℃.
Install for convenient, said humidity sensor, temperature sensor are installed on automobile air-conditioning evaporator fin place; Said humidity sensor, temperature sensor become one.
Of the present inventionly prevent the device that automobile air-conditioning evaporator goes mouldy and control method is simple in structure, cost is low, be easy to realize, can avoid evaporimeter to go mouldy, thereby improve the air ambient in the car, the raising comfort level.
