Problems solved by technology

Although the air-conditioning HVAC (Heating, Ventilation and Air Conditioning, that is, heating, ventilation and air conditioning) is equipped with a drain pipe, it can only remove part of the condensed water, and cannot completely drain the water on the surface of the air-conditioning evaporator.

Embodiment 1

[0032] like figure 1 Shown, the present invention prevents the control method that automotive air conditioner musty smell produces, comprises the following steps:

[0033] 1) Detect whether the automobile air-conditioning refrigeration system is in normal working condition: if yes, proceed to step 1); if not, proceed to step 2);

[0034] The normal working state of the automobile air conditioning and refrigeration system refers to the state when the air conditioning and refrigeration system is turned on, and the abnormal working state of the automobile air conditioning and refrigeration system refers to the state when the air conditioning and refrigeration system is not turned on but the ventilation system is turned on.

[0035] 2) When it is detected that the automobile air-conditioning and refrigeration system is in an abnormal working state, control the ventilation system in the automobile air-conditioning and refrigeration system to work on a delayed basis, so as to dry th...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that this embodiment does not have the rain sensor state detection unit in Embodiment 1.

[0055] Other structures and uses in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a control method for preventing musty odor from car air-conditioners, which includes the following steps of 1) detecting whether a car air-conditioner refrigerating system runs normally or not, if so, then keeping the step 1), if not, then going to the step 2); and 2) controlling a ventilation system in the car air-conditioner refrigerating system to work in a delaying mode so as to dry the surface of an evaporator of the car air-conditioner refrigerating system and then turning off the ventilation system. The invention further provides a control system for preventing musty odor from car air-conditioners and a car utilizing the same. The control method is capable of effectively solving the problem that musty odor is generated along with air supply of air-conditioners due to humid surfaces of evaporators when the car air-conditioners are started.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a control method for preventing the musty smell of an automobile air conditioner, a control system for preventing the musty smell of the automobile air conditioner and an automobile using the control system. Background technique [0002] In the hot summer, when people enjoy the comfortable driving environment provided by the air conditioner in the car, they often suffer from the musty smell of the air from the air conditioner. When the air conditioner is working normally, the evaporator cools and dehumidifies the hot air passing through it, and the water vapor in the air will condense and form water droplets when passing through the surface of the air conditioner evaporator. These condensation droplets usually absorb some impurities and dust from the outside air. If the car often drives in a place with bad air or a lot of dust, more impurities and dust in the air will be depos...
