The Growing Demand for Sustainable HVACR Solutions
Sustainability is no longer a trend—it’s a necessity. As buildings worldwide account for nearly 40% of global energy consumption, optimizing energy use in HVACR (Heating, Ventilation, Air Conditioning, and Refrigeration) systems has become a priority. Governments and industries alike are implementing stringent energy efficiency standards to reduce carbon footprints and operational costs.
One such regulation is the Singapore Green Mark Standard SS591:2021, which emphasizes the importance of accurate temperature monitoring in chilled water systems. This ensures HVACR systems operate at peak efficiency while minimizing energy wastage. But how can building owners, facility managers, and engineers achieve this? The answer lies in using high-accuracy temperature sensors tailored for long-term performance.
The Role of Precision Temperature Sensors in HVACR Energy Efficiency
Temperature sensors play a crucial role in HVACR systems, particularly in chilled water applications where even minor inaccuracies can lead to significant energy losses. A deviation of just 0.5°C in temperature measurement can result in unnecessary energy consumption, increasing operational costs.
To mitigate this, Acez Instruments introduces the SS591 Chilled Water System Energy Efficiency Temperature Sensor (Green Mark Temperature Sensor)—a sensor designed to meet the highest industry standards, ensuring reliable and precise temperature monitoring for optimized HVACR performance.
Key Features of the SS591 Green Mark Temperature Sensor
1. Regulatory Compliance
The SS591 sensor is manufactured according to ASHRAE Guideline 22:2015 and SS591:2021 requirements, making it compliant with international and local energy efficiency standards. This ensures that building operators can seamlessly integrate the sensor into their existing energy management strategies.
2. Exceptional reliability and precision
- RTD PT100 (1/10 DIN): Delivers an accuracy of ±0.03°C at 0°C, ensuring stable and precise readings.
- Thermistor 10K: Offers an accuracy of ±0.05°C within the 0-50°C range, making it ideal for energy-efficient HVACR applications.
- Calibrated Using Fixed Points: Ensuring the highest accuracy, the sensor is calibrated at the Triple Point of Water (0.01°C) and Gallium Melting Point (29.7646°C)—scientifically recognized reference points for temperature calibration.
3. Long-Term Stability & Durability
Unlike conventional sensors that drift over time, the SS591 sensor is engineered with:
Robust construction to withstand harsh environmental conditions, reducing the need for frequent recalibration and replacements.
Vibration-proof, open-ended threaded thermowell, maintaining accuracy over extended periods.
4. Customization & Quality Assurance
Every building and HVAC system is unique. That’s why Acez Instruments offers tailored manufacturing services to meet specific client requirements. Additionally, our sensors come with accredited calibration certifications, ensuring top-tier performance from day one.
Why Investing in High-Precision Sensors is a Smart Move
Inaccurate temperature readings can lead to overcooling or undercooling, directly impacting energy efficiency, equipment lifespan, and operational costs. By choosing precision-engineered sensors like the SS591, businesses can achieve:
