Refrigerant Charge Level Detection |
| 摘要 |
An exemplary embodiment of a refrigerant charge monitoring system includes first and second sensors. The first sensor is operable for sensing temperature of a liquid refrigerant line that is connected to, within, or extending from an outlet of a condenser. The second sensor is operable for sensing pressure of the liquid refrigerant line. A controller is configured to determine at least one target pressure value from the sensed temperature of the liquid refrigerant line. The controller is configured to determine if the level of refrigerant charge is at, above or below an acceptable level based on a comparison of the sensed pressure of the liquid refrigerant line to the at least one target pressure value. |

1. A refrigerant charge monitoring system, comprising:
a first sensor operable for sensing temperature of a liquid refrigerant line that is connected to, within, or extending from an outlet of a condenser; a second sensor operable for sensing pressure of the liquid refrigerant line; and a controller configured to determine at least one target pressure value from the sensed temperature of the liquid refrigerant line, the controller being configured to determine if the level of refrigerant charge is at, above or below an acceptable level based on a comparison of the sensed pressure of the liquid refrigerant line to the at least one target pressure value.
