Chiller Systems Sensor Types and Locations
Sensors play a crucial role in chiller systems by providing valuable data for monitoring, control, and optimization. Here are some common sensor applications in chiller systems:
Pressure Transducers
Pressure transducers are a crucial component in chiller systems, enabling accurate pressure measurement and contributing to the overall efficiency and reliability of the system.
Differential Pressure Measurement
Several instruments can be used to measure the differential pressure across a chiller. The differential pressure measured corresponds to the flow rate; the higher the flow, the higher the DP. Differential pressure switches or transmitters are most common.
Temp/RH sensor
Used to maintain occupant comfort humidity and temperature levels via precise relative humidity (RH) and temperature measurement.
Immersion Sensors
These are used to monitor the inlet and outlet temperatures of the chilled water and the refrigerant. This data helps in ensuring efficient cooling and detecting any temperature-related issues.
Strap-on/Pipe Mount sensors
These are used to monitor the inlet and outlet temperatures of the chilled water and the refrigerant when the pipe is too small for an Immersion sensor.
Leak Detection
Leak detection sensors are crucial for identifying refrigerant or water leaks, which can have environmental and safety implications.
Current Sensors
These sensors monitor the current drawn by the chiller's motors and compressors. Unusual current spikes might indicate issues with the equipment or the need for maintenance.
Flow Switch
Used as proof that water is flowing through the system
Power Meters
These sensors monitor various electrical parameters like voltage, current, and power factor, providing insights into the electrical performance of the chiller.
