This page serves as a valuable resource for our HVAC students, offering a curated selection of links to articles and videos available on the web. While these materials can provide insightful information and additional perspectives, it's crucial to emphasize that they are NOT a substitute for mandatory class attendance at Eastwick College. Rather, they are intended to complement and enhance your learning experience. Attending classes is essential for engaging in discussions, receiving personalized instruction, and fostering a sense of community within the classroom.

Refrigeration Cycle / Heat Pump

• Refrigeration Cycle by CM
• Phase Change or Saturated State of Water and Required Energy by RW notice the required energy to transform water from liquid to vapor and vice versa, also critical to understand the difference between latent and sensible heat.
• The refrigeration Cycle by RW, extra attention to temperature changes throughout the system in particular the NO change of temperature at the saturated state exactly at Evaporator and Condenser (mix vapor-liquid). Developing an understanding of the Fundamentals of the Refrigeration cycle is essential and is binary in nature either the student understands or the student does not understand.  
• Heat Pump is reversed refrigeration cycle at which point we absorb the heat from the outdoor and reject heat indoors. As such the evaporator becomes the condenser and the condenser becomes the evaporator and as such we drop those names and refer to them as outdoor coils and indoor coils.
