Embodiment Construction
[0030] Example implementations will now be described more fully with reference to the accompanying drawings.
[0031] To increase efficiency and reduce downtime, examples of fault detection systems and methods for monitoring and maintaining cooling system operation at expected levels are disclosed herein. This includes detecting degradation of one or more components within a cooling system (eg, an air conditioning system). Degradation can be detected at an early stage allowing maintenance and / or countermeasures to be performed before component failure. These examples minimize false alarms and provide reliable degradation detection. These examples apply to various different types and models of cooling systems and are not limited to specific thresholds for a particular type and / or model of air conditioning system. One or more of these examples provide the detection described without requiring servers for storing large amounts of historical data. Sensing can be provided by a s...

A method comprising: determining whether a cooling system is operating in a cooling mode such that the cooling system is not operating in a reheat mode, a humidification mode, or a dehumidification mode; determining whether the cooling system is operating in a compressor mode such that the cooling system is not operating in a pump operating in a refrigerant saver mode; determining whether the cooling system is in a steady state; and, while the cooling system is operating in a cooling mode and a compressor mode and in a steady state, evaluating one or more rules to determine whether there is degradation in the cooling system sign. The method also includes, after the evaluation, generating a degradation evaluation value to indicate whether the one or more rules are satisfied; and based on the degradation evaluation value, generating an alert signal or executing a countermeasure.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to US Invention Patent Application No. 15 / 410,144, filed January 19, 2017 and also claims the benefit of US Provisional Application No. 62 / 293,798, filed February 11, 2016. The entire disclosures of the applications cited above are incorporated herein by reference. technical field [0003] The present disclosure relates to cooling systems, and more particularly to the detection of component degradation within cooling systems. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] The cooling system is used for air conditioning and refrigeration of food. Variations in the performance and / or failure of cooling systems can negatively impact human health and comfort, food safety, and / or business profitability. Cooling systems are used in many different applications where fluids are to be co...
