2. Cooling load temperature difference calculation method

   en.wikipedia.org/wiki/Cooling_load_temperature...

   The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.

   Split systems are preferred and widely used worldwide except in North America. In North America, split systems are most often seen in residential applications, but they are gaining popularity in small commercial buildings. Split systems are used where ductwork is not feasible or where the space conditioning efficiency is of prime concern. [33]

4. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   The building owner can monitor the system and respond to alarms generated by the system from local or remote locations. The system can be scheduled for occupancy or the configuration can be changed from the BAS. Sometimes the BAS is directly controlling the HVAC components. Depending on the BAS different interfaces can be used. [4]

   As stated in GR-3028, most equipment environments maintain cool front (maintenance) aisles and hot rear (wiring) aisles, where cool supply air is delivered to the front aisles and hot air is removed from the rear aisles. This scheme provides multiple benefits, including effective equipment cooling and high thermal efficiency.

6. Troubleshooting - Wikipedia

   Troubleshooting can also take the form of a systematic checklist, troubleshooting procedure, flowchart or table that is made before a problem occurs. Developing troubleshooting procedures in advance allows sufficient thought about the steps to take in troubleshooting and organizing the troubleshooting into the most efficient troubleshooting ...

7. Chilled beam - Wikipedia

   en.wikipedia.org/wiki/Chilled_beam

   A chilled beam is a type of radiation/convection HVAC system designed to heat and cool large buildings through the use of water. [1] This method removes most of the zone sensible local heat gains and allows the flow rate of pre-conditioned air from the air handling unit to be reduced, lowering by 60% to 80% the ducted design airflow rate and the equipment capacity requirements.
