Low Temperature Component
When the outdoor temperature is below the operating temperature lower limit specified for the product, the condensing pressure of the system for the outdoor unit condenser with natural cooling may still be below the safe operating pressure of the compressor. A low temperature component is required to address this issue.
The low temperature component automatically controls the condensing pressure to ensure that the smart cooling product works safely and reliably at an outdoor ambient temperature of –40°C.
- When the outdoor condensing pressure is lower than the designed opening pressure of the condensing pressure regulator valve, the regulator valve closes and the differential pressure valve opens. The refrigerant at the compressor outlet is bypassed to the liquid storage unit of the low temperature component through the differential pressure valve, ensuring that the condensing pressure stays within a safe and reliable operating range.
- When the condensing pressure is higher than the designed opening pressure of the condensing pressure regulator valve, the regulator valve opens and the differential pressure valve closes. The refrigerant at the compressor outlet flows to the liquid storage unit of the low temperature component through the condenser, and the system runs properly.
