Abstract
The invention aims to provide a device for preventing an evaporator of an automobile air conditioner from being mildewed and a control method thereof, which aim to prevent the evaporator from being mildewed so as to improve the air environment and the comfort level in an automobile. The device for preventing the evaporator of the automobile air conditioner from being mildewed comprises a controller for the air conditioner and an air conditioner blower which is controlled by the controller. The device for preventing the evaporator of the automobile air conditioner from being mildewed has the key point by comprising a humidity sensor arranged in the evaporator of the automobile air conditioner. The humidity sensor is connected with the controller for the air conditioner. The control method for the device for preventing the evaporator of the of the automobile air conditioner from being mildewed comprises the following steps: after turning off an air conditioner compressor by the controller, detecting the humidity of the surface of the evaporator by the controller by utilizing the humidity sensor; and when the humidity of the surface of the evaporator is higher than first preset humidity, controlling the blower to continue working by the controller until the humidity of the surface of the evaporator is lower than second preset humidity, wherein the first preset humidity is greaterthan the second preset humidity.
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, being 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 treated, 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 to avoid evaporimeter, thereby improve the interior air ambient of car, improve comfort level.
The device that prevents that automobile air-conditioning evaporator from going mouldy of the present invention comprises the controller of air-conditioning and is subjected to the air conditioner blower of described controller control, key is also to comprise a humidity sensor that is installed in the automobile air-conditioning evaporator, and described 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, humidity up to evaporator surface is lower than second predetermined moisture, and described 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 described 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; Described 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 more high, condensed water is just more high by the possibility of natural evaporation, the possibility that evaporimeter goes mouldy is just more little, therefore survey the temperature of evaporator surface by 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%; Described first predetermined temperature is 2 ℃, and second predetermined temperature is 10 ℃.
Install for convenient, described humidity sensor, temperature sensor are installed on automobile air-conditioning evaporator fin place; Described 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.
