What happens to the evaporator in a refrigeration system with low condenser pressure?

In a refrigeration system, the operation of the evaporator is closely tied to the pressures in both the evaporator and the condenser. When the condenser pressure is low, it affects the refrigerant cycle and can lead to improper feeding of the evaporator.

Low condenser pressure means that the refrigerant is not condensing effectively in the condenser, which translates to lower pressure and temperature in the system. This can disrupt the flow of refrigerant into the evaporator. In this situation, the system may struggle to maintain the correct amount of refrigerant flow, which results in an insufficient supply of refrigerant in the evaporator. This can ultimately lead to the evaporator not absorbing enough heat from the surrounding environment, diminishing its overall efficiency and performance.

Understanding the relationship between the pressures in the refrigerant cycle helps in diagnosing and maintaining proper functionality in refrigeration systems.
