Product Overview
OVERVIEW
Inverter - The ACiQ-18-EHPD 1.5 ton central inverter heat pump utilizes inverter technology to convert AC power to DC, allowing the compressor to adjust its speed. This enables the condenser to modify its BTU output based on the current demand, providing efficient and adaptable performance throughout varying weather conditions.
Learning Condenser - Equipped with advanced sensors, this condenser monitors indoor and outdoor air temperature, duct pressure, refrigerant temperature, and overall performance. During the initial startup, it enters a learning mode, optimizing future operations for maximum efficiency by collecting and storing data.
Adaptive Sizing - With its self-adjusting inverter design, the ACiQ-18-EHPD can be sized based on your heating needs. Standard heat pumps may cause discomfort during summer when sized for heat, but this unit automatically adjusts to function like a smaller unit, ensuring ideal cooling performance without excess humidity.
