Measuring air flow in an HVAC duct can be a tricky business. Paddle wheel and turbine flow meters introduce not only resistance but maintenance issue due to accumulated dust and debris. Being able to ...

Variant refrigerant flow technology is designed to give building occupants more comfort and more energy-efficient control via zoning. Supported by integrated controls and sensors, VRF accomplishes ...

Purdue University engineers have developed a second-generation smart accumulator with oil circulation ratio (OCR) sensing capabilities for heating, ventilation, air conditioning and refrigeration, or ...

A variable air volume box controls the air flow to a given space. When the space is unoccupied, the box closes off the heat and cooling to a minimum flow or turns it off when a building is not being ...

An HVAC pressure sensor is particularly important in the cooling cycle—which includes compression, condensation, expansion, and evaporation—where it helps regulate refrigerant flow. Proper airflow ...

Solution is the first with full UL Recognition for the use of R454A, R454B, R454C, and R32 under the 4th edition of UL 60335-2-40 Sensata Resonix™ RGD Sensor detects the presence of A2L refrigerant ...
