Abstract
The present disclosure provides a hybrid intercooler system integrated with an air conditioning system and a method of controlling the same. In accordance with the present disclosure, it is possible to stabilize the temperature of intake air passing through the inlet of an intercooler using a water cooling unit and increase the cooling efficiency of the intercooler using an air cooling unit. Consequently, it is possible to improve engine power and fuel efficiency.
Claims20
A hybrid intercooler system integrated with an air conditioning system, comprising:
- an air cooling unit configured to exchange heat between outside air passing through outer walls of a plurality of compressed intake air passages and compressed intake air flowing in the compressed intake air passages so as to cool the compressed intake air;
- a water cooling unit configured to exchange heat between a water-cooling-unit refrigerant surrounding the outer walls of the compressed intake air passages and the compressed intake air cooled by the air cooling unit,
- wherein the water cooling unit comprises:
- a water-cooling-unit refrigerant tank configured to surround the compressed intake air passages, and
- a bypass line branched from a receiver drier, and configured to communicate with a compressor through the water-cooling-unit refrigerant tank;
- and
- a first bypass valve and a second bypass valve mounted on the bypass line at locations upstream and downstream of the water-cooling-unit refrigerant tank, respectively, so as to open or close the bypass line.
A method of controlling a hybrid intercooler system integrated with an air conditioning system, comprising:
- determining whether or not an operation signal of an air conditioning system is applied ;
- starting operation of the air conditioning system by opening first and second air conditioning valves and operating a compressor , when the operation signal of the air conditioning system is determined to be applied;
- measuring a first temperature by measuring a temperature of compressed air at an outlet of the hybrid intercooler system integrated with the air conditioning system, after the starting operation of the air conditioning system;
- determining whether the measured first temperature exceeds a predetermined first reference temperature;
- and
- starting operation of a first water cooling unit by opening first and second bypass valves , when the measured first temperature exceeds the predetermined first reference temperature.
