What are the target suction pressure and head pressure?

Target suction pressure and head pressure refer to specific operating parameters in refrigeration and air conditioning systems. The target suction pressure is the desired pressure in the evaporator, typically measured in psi or bar, which ensures efficient heat absorption from the environment. Head pressure, on the other hand, is the pressure in the condenser, necessary for proper refrigerant condensing and is influenced by ambient temperature and system design. Maintaining these pressures within their target ranges is crucial for optimal system performance and energy efficiency.
