24/07/2009· LEED is very specific about the location of sensors, requiring them to be between 3 and 6 feet above the finished floor in what is known as the “breathing zone.” This is the space in a room where people inhale and exhale. Previous standards of practice put sensors in the return air duct, something unacceptable under LEED because this location does not sense actual room conditions that humans …

8 possible reasons behind AC not cooling properly - Ideas by Mr Right

29/05/2019· A compressor is the heart of an air conditioning unit which is responsible for cooling your room. If the air conditioner does not cool, the compressor might be defective. The compressor is a motor which compresses the refrigerant or coolant and circulates the refrigerant through the evaporator and condenser coils. If the compressor goes bad the cooling cycle does not start and the AC fails to cool.

LEED and Standard 62 - Taylor Engineering

The LEED credit equated high ACE with high ADPI. They are not the same, although high ADPI usually results in high ACE. But, ADPI only applies to cooling systems that inherently have high ACE. ADPI does not apply to heating systems where low ACE can occur. Thus, ADPI is not a good surrogate for ACE.

To solve the challenge, scientists in Europe were early to develop a low-cost CO2 sensor as a means of identification and control. These small devices measured the amount of carbon dioxide in a room. The theory is simple: the more people in a room, the more carbon dioxide exhaled, and the more fresh air that was needed. Conversely, if CO2 levels are normal, the HVAC system can be set on standby until …
