This chapter discusses the HVAC systems. It begins with an introduction to a graphical representation of air-conditioning processes called the psychrometric chart. Next, an air conditioning system is introduced followed by a discussion about how it can be adapted to serve many spaces. It is broad...

Reduces energy consumption Rule of Thumb Approximately 0.55C (1F) of condenser water temperature increase, results in approximately 1.5% to 2% reduction in chiller efficiency Reference: Cooling Tower Institute USA * Discussion Topics What is HVAC Types of Equipment Used Basic Refrigeration System Types...
Each zone is served by at least one VAV box—or, more accurately, a VAV terminal. The terminal is controlled by a temperature (generally the BAS system) to open and close to provide more or less air to the zone. As VAV terminals open, the static pressure in the supply duct decreases,...
FCU, AHU, PAU, RCU, MAU, FU, HRV, FAU, OAC, and EAF are often heard in the HVAC industry and air conditioning water system - a series of strange terms. So, what do the concepts that these letters represent? What is the difference between them? 1. FCU (full name: Fan Coil Unit)...
2.1 General. The first step in HVAC system design is to select indoor and outdoor summer and winter design conditions. There are various sources for this information, but among the best are DOD Military Handbook MIL-HDBK-1190 and Naval Facilities ...
An HVAC system at BSL-2 and above must be HEPA in/HEPA out. The BSL-2 air can be recirculated to the BSL-2 area if it is HEPA filtered. At BSL-2 and above, redundant backup air handling units (AHUs) or independent exhaust fans are required, in case one AHU fails; the diff...
ps = system pressure patm = atmospheric pressure Atmospheric Pressure Atmospheric pressure is pressure in the surrounding air at – or “close” to – the surface of the earth. The atmospheric pressure vary with temperature and altitude above sea level. ...
