If defrost isn’t working, something in the chain is broken. This step-by-step approach shows you exactly where to look and what to test.

Despite signs of improvement heading into 2026, conditions remain fragile. Affordability pressures, tight lending standards, ...

Quilt's heat pumps are built containing a suite of sensors, which have delivered mountains of data that allow its engineers ...

Abstract: This letter proposes a sparse identification of nonlinear dynamics—physics informed neural network—particle swarm optimization algorithm for optimizing the air-gap design of transformers ...

Federal energy data shows widespread HVAC installation issues, with airflow and duct design often limiting system performance during winter demand. Proper airflow is essential to system performance.

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

Abstract: Power transformers play a pivotal role in power grids, yet they are invariably exposed to short-circuit impacts. Precise assessment of the winding mechanical strength is crucial for ensuring ...
