When the high and low temperature integrated machine is running, the system prompts that the low pressure operation is usually due to:
The refrigerant is insufficient, check and repair whether there is leakage, and replenish the refrigerant.
If the filter element is blocked, clean or replace the filter element.
The opening time of the expansion valve is too short. Adjust the opening of the expansion valve properly.
Clean or replace the capillary tube of the refrigeration heating and temperature control cycle.
