Q1: What is a split type heat pump?
A: A split system heat pump consists of an outdoor compressor/heater unit and one or more indoor units. This configuration allows flexible placement, multi-zone control and less indoor disruption compared to packaged units.
Q2: Why use R32 refrigerant in the heat pump?
A: R32 is a modern refrigerant with better thermodynamic efficiency and lower Global Warming Potential (GWP) compared to many older refrigerants. Choosing an R32 heat pump supports sustainability and high-efficiency operation.
Q3: What does DC inverter mean for this system?
A: A DC inverter heat pump adjusts the speed of the compressor and fan motor in response to actual heating or cooling demand. This results in smoother temperature control, fewer start/stop cycles, lower noise, and improved energy efficiency.
Q4: Can this system handle both heating and cooling?
A: Yes. This home heat pump system is designed for both heating and cooling in residential applications, making it a comprehensive house heat pump solution rather than a heating-only device.
