| 摘要 |
The present invention relates to refrigerant leakage sensing system and method, and more particularly, to refrigerant leakage sensing system and method for sensing the occurrence or not of refrigerant leakage. In the present invention, temperature sensors are mounted at inlet and outlet sides of an evaporator, respectively. When a difference between the temperatures sensed by the temperature sensors becomes above a predetermined value, a control unit determines that the refrigerant leaks. Then, the refrigerant leakage is displayed to a user. Accordingly, the present invention makes it possible to cope with the problem caused from the occurrence of the refrigerant leakage and to exchange parts such as refrigerant pipes with new ones at an early stage by automatically sensing the refrigerant leakage with low cost.
