6+ HVAC Head Pressure: Definition & Causes Explained

In heating, ventilation, and air conditioning (HVAC) systems, the term refers to the pressure exerted on the discharge side of a compressor. It represents the force required to move refrigerant through the condenser and associated components, including the discharge line and any other restrictions in the high-pressure side of the system. As an example, a system operating with a high measurement indicates increased resistance to refrigerant flow, potentially due to a dirty condenser coil or a blockage in the refrigerant lines.

Maintaining appropriate readings is crucial for optimal system performance and longevity. Deviation from specified ranges can lead to reduced efficiency, increased energy consumption, and potential damage to the compressor. Understanding and monitoring this parameter allows technicians to diagnose potential problems, prevent system failures, and ensure efficient operation. Its historical significance is tied to the evolution of refrigerant-based cooling systems and the need for precise control and monitoring of their operational parameters.

APUSH: Hawley-Smoot Tariff Definition + Impact

The Hawley-Smoot Tariff, a significant legislative action in American history, refers to a law enacted in 1930 that substantially raised import duties on over 20,000 goods entering the United States.

While intended to protect American industries and jobs, it triggered retaliatory tariffs from other nations, leading to a sharp decline in international trade. Historians and economists often cite it as a contributing factor to the severity and duration of the Great Depression. Its legacy serves as a cautionary tale regarding the potential pitfalls of protectionist measures.
