| titleOfInvention | Freezing prevention device of vehicle air conditioning system |
| abstract | The present invention relates to an apparatus for preventing ice of an air conditioning system for a vehicle, and an object of the present invention is to prevent water from being frozen on the surface of the evaporator due to an excessively low temperature of the refrigerant passing through the evaporator.n n n In order to achieve this object, the present invention includes a compressor, a gas cooler, an expansion valve, an evaporator, and an internal heat exchanger, and in a vehicle air conditioning system using carbon dioxide (CO 2 ) as a refrigerant, the refrigerant flowing from the internal heat exchanger to the expansion valve A bypass line communicating the internal heat exchanger with the inlet side of the evaporator to bypass the to the inlet side of the evaporator; Pressure sensing means for sensing a pressure corresponding to the temperature of the refrigerant passing through the evaporator; When the pressure of the pressure sensing means is lower than the set pressure by comparing the pressure of the refrigerant inputted from the pressure sensing means with the preset pressure, it is determined that the refrigerant of the evaporator drops below the set temperature and water is frozen on the surface of the evaporator. A controller for outputting; And an on / off valve opening the bypass line to bypass the refrigerant flowing from the internal heat exchanger to the expansion valve according to the control signal of the controller to the inlet side of the evaporator. |
