(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 of the outdoor unit.
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 of the outdoor unit.
Target low-pressure and high pressure temperature depends on system capacity, capacity of compressor operation,
pipe length, and capacity shift switch settings.
