Simulation testing is essential to understand how air source heat pumps perform in real-world conditions at low temperatures. While many systems specify low-temperature performance on paper, controlled testing in sub-zero environments helps verify their stability, energy efficiency, and defrost performance in sustained low-temperature environments.
At Leomon, we use indoor climate chambers to simulate outdoor environments as low as -25°C. These tests monitor system behavior over a long period of time, including compressor frequency, defrost cycles, and energy consumption. Through these evaluations, we optimize features such as smart defrost algorithms and variable speed operation, which improves cold weather performance across all product lines.
One of the heat pumps that has been tested in extreme conditions is the 75kW CO2 commercial air source heat pump. Designed for large-scale heating and cooling needs, this air source heat pump uses low-GWP CO2 refrigerant, full inverter control, and an intelligent monitoring system. These technologies ensure that the unit provides stable output and maintains a high seasonal efficiency ratio (COP) even during sustained low-temperature operation.
While actual field conditions vary, our simulation approach ensures that systems like our 75kW CO2 air source heat pump will provide consistent heating even in demanding cold climate applications. This makes it a solid choice for schools, hotels, apartment buildings, and other commercial projects that need to operate efficiently during the winter.
Ultimately, the goal of simulation is not to achieve perfect numbers in the lab, but to ensure that our air source heat pumps maintain comfort and stability in cold climates, no matter how much the temperature drops.
