Abstract
An apparatus for detecting a deficiency in refrigerant in a refrigeration system is disclosed. The apparatus has an extension arm for mounting onto a refrigerant line downstream of the expansion valve. The extension arm is cantilevered for amplifying the vibrations of the refrigerant system when deficient in refrigerant. Mounted on the extension arm is an accelerometer for detecting this vibration and sending an electrical signal upon detection thereof. Electrically connected to the accelerometer is a signalling device for providing a warning or alarm signal of a deficient refrigerant situation.
Claims7
A device for detecting a deficiency of refrigerant in a refrigeration system, said device comprising
- an extension arm forming a cantilever and connected to a refrigeration system downstream of an expansion valve of said refrigeration system, said extension arm amplifying vibrations generated by the refrigeration system when deficient in refrigerant,
- an accelerometer mounted on the extension arm for generating a signal when said extension arm is vibrated, and
- alarm means responsive to said signal for generating an alarm signal.
