5.7 Low Temperature Component
Working Principle
When the outdoor temperature is below the operating temperature lower limit
specied for the product, the condensing pressure of the system for the outdoor
unit condenser with natural cooling may still below the safe operating pressure of
the compressor. A low temperature component is required to address this issue.
The low temperature component intelligently controls the condensing pressure to
ensure that the equipment can work safely and reliably at an outdoor ambient
temperature as low as –40ºC. When detecting that the outdoor condensing
pressure is low, the pressure stabilizing valve automatically opens to bypass hot
gas to the liquid storage tank, thereby ensuring that the condensing pressure stays
in the range for safe and reliable operation. When detecting that the condensing
pressure exceeds the threshold, the pressure stabilizing valve automatically closes
the bypass.
