Toronto, ON — A prototype cold climate residential air-source heat pump is being put to the test in Toronto. Terravis Energy is testing the prototype in a specialized climate chamber at its facility.
“We are engaged in this rigorous and severe testing protocol because Terravis’s mission is to offer a zero-emission residential Heat Pump that sets new standards in cold-weather performance,” said Lorenzo Rossi, CEO of Terravis Energy.
An air-source heat pump, like the one Terravis is testing, utilizes the phase change of a proprietary fluid to transfer heat. The Terravis heat pump is designed to operate at lower temperatures and offer a modular design for flexible placement in homes
According to Terravis, its’ testing chamber conducts extensive cold-weather trials during product development. For the heat pump, Terravis will conduct tests that monitor performance across a range of 12 temperature points from 14 F (-10 C) to -31 F (-35 C).
These tests include checking four refrigerant pressure zones, airflow, and the energy consumption of each component. The aim is to optimize the heat pump’s efficiency and performance at various temperatures. The heat pump’s operation is also assessed at multiple set temperatures within this range.
Plans are in place to expand the testing to include its cooling capabilities at higher temperatures.
