Which condition can cause high discharge pressure in a refrigeration system?

High discharge pressure in a refrigeration system is primarily influenced by the capacity of the condenser to remove heat. When the condenser is unable to effectively dissipate heat, it can lead to an increase in the refrigerant's discharge pressure due to the buildup of pressure in the condenser.

Insufficient cooling water to the condenser directly affects its efficiency; when there is a lack of cooling water, the condenser may not be able to reach the expected temperature drop, resulting in higher discharge pressures. This scenario can occur due to several reasons such as reduced water flow rates, blockages in the water circuit, or water temperature being too high.

Increased suction pressure typically indicates that there is a higher pressure on the side of the evaporator where the refrigerant is being sucked in. Although this can lead to an increase in system capacity and performance, it does not directly cause high discharge pressure, as it mainly affects the low side of the system.

Excessive oil in the system can lead to operational issues, including compressor oil management and heat transfer efficiency; however, it is not a direct cause of high discharge pressure. Instead, it could lead to other types of malfunctions or inefficiencies within the refrigeration system.
