2-4-3 Capacity Control
(1) Capacity of compressor operation
By combining the operation of inverter compressors, the amount of required refrigerant circulation acceding to cooling and heating
load can be supplied from compressor efficiently.
The inverter compressor is able to control the amount of required refrigerant circulation in details.
(2) Target low-pressure and high-pressure control
In order to make the evaporation pressure of the indoor unit at the proper pressure on a variety of operations,
capacity of the compressor will be controlled by low-pressure sensor.
In order to make the condensation pressure of the indoor unit at the proper pressure on a variety of operations,
capacity of the compressor will be controlled by high-pressure sensor.
Target low-pressure and high pressure temperature depends on system capacity, capacity of compressor operation,
pipe length, and capacity shift switch settings.
<Cooling>
<Heating>
<Cooling main / Heating main>
In order to keep evaporation pressure / condensation pressure of the indoor unit at the proper pressure on a
variety of operations, capacity of the compressor and the capacity Heat exchange(incl. fan controll) will be
controlled by both of pressure sensor at the sametime
Ex) Combnation of 65cc compressor / Heating (Heating main)
*The maximum speed: 115 rps
Cooling (Cooling main) 100rps
Heating (Heating main) 115rps
