Pressure in your head can have …Low condensing (head) pressure: The restricted airflow over the evaporator coil will cause the refrigerant in the evaporator not to see a heat load, thus it will not be completely vaporized. With no heat load to be rejected in the condenser, the condensing pressure and temperature have to elevate to reject heat to the ambient. Significance of Monitoring Head Pressure. Regularly monitoring head pressure is crucial for various reasons: Energy efficiency considerations: A well-regulated system consumes less power. System longevity: Systems with proper head pressure often have longer lifespans. Maintaining comfort levels: Stable head pressure ensures consistent temperatures. The most common cause of high head pressure in a refrigeration system is a loss of refrigerant. This can be caused by leaks in the system, improper charging, or by running the system for too long without maintenance. Other causes of high head pressure can include dirty condenser coils, restricted airflow, and faulty control valves.High head pressure in a walk-in cooler can be caused by various factors, including a dirty or blocked condenser, an overcharged system, or inadequate airflow around the condenser.
