A basic understanding of the content within our Air Conditioning Systems program is recommended as a prerequisite to this program.
Application options differ substantially between air source heat, hybrid, closed loop geo, open loop geo and inverter-driven heat pumps. Each of these systems are reviewed and contrasted.
Expanded performance data is a tremendous resource in selecting the proper equipment, performance testing, and diagnostics. Expanded data is showcased and examples illustrate how it can be applied in day-to-day use.
System design, thermal and economic heat pump balance points are explained.
Heat pump defrost options are compared to demonstrate function, differences in operating efficiency, comfort and energy consumption.
The proper operation of reversing valves, accumulators and refrigerant metering devices that are unique to heat pumps are examined in detail.
Refrigerant flow for both cooling and heating mode is contrasted to simplify flow diagnostics and troubleshooting.
The program concludes with a review of the testing required for each heat pump category, to verify capacity and performance of the heat pump and HVAC system.
