Abstract
A method and/or apparatus determines whether a refrigeration (or other cooling) related system is operating within normal parameters by comparing reference data derived from ideal or normal conditions within the system. Data regarding the actual operating parameters of the system is provided via a set of microsystem sensors disposed throughout the refrigeration or cooling system. The sensors are in some embodiments wireless, and in some advantageous embodiments includes MEMs sensors.
Claims20
An arrangement, comprising:
- a plurality of MEMs sensors, each sensor operably coupled to measure a parameter of a refrigeration system, each sensor coupled to one of a plurality of wireless transmission devices;
- a processing circuit configured to receive first information based on the parameters of the refrigeration system from the wireless transmission devices, the processing circuit further operable to,
- compare the first information to one or more reference values;
- and
- generate a first message conditionally, based on the result of the comparison.
A method comprising:
- a) generating first information based on a measurement of a parameter of a refrigeration system in each of a plurality of MEMs sensors;
- b) transmitting the first information wirelessly to a processing circuit;
- c) comparing the first information to one or more reference values;
- and
- d) causing the processing circuit to generate a first message conditionally, based on the result of the comparison.
An arrangement, comprising:
- a plurality of wireless sensor modules, each sensor module operably coupled to measure a parameter of a refrigeration system, each sensor module including a wireless transmission device;
- a processing circuit configured to receive first information based on the parameters of the refrigeration system from the wireless transmission devices, the processing circuit further operable to,
- compare the first information to one or more reference values;
- and
- generate a first message conditionally, based on the result of the comparison.
