HVAC-R for Green Buildings

HVAC-R systems play a very important role in a green building to reduce energy consumption, deliver a comfortable and healthy work environment. Under the trend of building green and comfortable development, effective control of building energy consumption has become one of the problems that countries are actively facing to solve. Industrial HVAC-R temperature sensors must operate under challenging conditions, including moisture, high humidity, and extreme temperatures. At the same time, environmental concerns call for energy efficiency in air handling units.

Energy consumption is a major cause for concern in the buildings sector, where heating, ventilation, air-conditioning, and refrigeration or HVAC-R systems are responsible for up to 60% of a commercial building’s energy consumption. All large commercial buildings have HVAC-R failures and much of the spent energy is wasted because of malfunctions in either the equipment itself or in the logic control systems. To achieve better performance from HVAC-R systems, interior monitoring can provide valuable feedback in terms of system operations, leading to insights for correcting inefficiencies and optimizing equipment. Monitoring can also identify opportunities for energy efficiency upgrades and provide validation for improvements that contribute toward LEED certification.

Market Sectors

Temperature Sensors are Crucial in HVAC-R Applications

Temperature sensors play an important role for HVAC-R applications; not only to control indoor room temperatures, but also to measure and control the temperature in installed pipes and ducts that supply buildings with heated water or cold air to enable the system to perform properly. Sensors enable diagnostics that help identify system or equipment issues that could reduce efficiencies or cause major breakdowns to occur. Sensor technologies help reduce downtime, improve productivity, and lower maintenance costs. When it comes to HVAC-R temperature measurements, a single point sometimes is not enough. High Accuracy Temperature Sensor measures temperature along a duct or across a sectional area, resulting in more accurate information about the overall conditions inside HVAC-R units. High Accuracy Temperature Sensors are commonly found in ducts and heat exchangers to help HVAC-R equipment run more efficiently. High Accuracy Temperature Sensor also provide accurate and reliable temperature measurement for low-temperature HVAC-R applications, such as chillers and industrial cooling towers. The sensors and controls can be stand-alone devices for indoor air and temperature monitoring or part of equipment installations that provide integration and automation functions. The recent trend towards smart buildings drives the need for more and more sensors and integration of equipment within sensor networks. Temperature sensor help make these networks more reliable, highly accurate and easy to maintain.

Get Advice from the Sensor Experts

Maintaining a complex heating and cooling system can be a major challenge 24/7. The purpose of a HVAC-R system is much more than ensuring you’re efficiently warming or cooling various spaces. An HVAC system also improves indoor air quality (IAQ) by detecting and removing contaminants in the air and making every occupant comfortable.

Sensors enable diagnostics that can help identify system or equipment issues that can reduce efficiencies or cause major breakdowns occur. From the ventilation system to the cooling, heating and refrigeration equipment within a facility, sensor technologies help reduce downtime, improve productivity, and lower maintenance costs while also improving efficiencies and reducing operating costs.

Whatever your HVAC-R application is, the most efficient control solution always starts with the best sensors. We are ready to help you select the right product for your application.
