4.1 Selecon Procedure
Step 1: Total heat load calculaon
Step 2: System conguraon
Step 3: Selecon of outdoor units
Notes:
1. If the required water temperatures of the heat emiers are not all the same, the Mini Heat Pump’s outlet water temperature seng should be set at the
highest of the heat emier required water temperatures. If the water outlet design temperature falls between two temperatures listed in the outdoor
unit’s capacity table, calculate the corrected capacity by interpolaon.
2. If the outdoor unit selecon is to be based on total heang load and total cooling load, select Mono units which sasfy not only the total heang load
requirements but also the total cooling load requirements.
Provisionally select Mini Heat Pump unit capacity based on nominal capacity
Correct capacity of the outdoor units for the following items:
Outdoor air temperature / Outdoor humidity / Water outlet temperature
