The latent heat is used to preheat the incoming air from outside, saving energy and improving efficiency. Commercial air conditioning Air conditioning for large buildings such as hotels, hospitals and other commercial buildings, providing suitable ventilation and space conditioning. Back to top T. It forms part of a larger HVAC system found in residential, commercial , and industrial buildings. Chiller A chiller is a machine that removes heat from a secondary cooling medium water, glycol solution, etc.
R407C was developed as a replacement for the ozone depleting R22. Back to top G. The unit can either have a down or end discharge, and can be used with both electric and gas heat.
The unit is defined as joule per second and can be used to express the rate of energy conversion or transfer with respect to time. PUE values can range from 1. See Data Centre Aisle Containment for more information. Convection The transfer of heat by changes of density in a fluid or gas as two fluid streams pass across each other.
Psychrometric Chart The psychrometric chart represents factors relating to the condition of air and its change of state, based on 1kg of air. Used extensively in air conditioning systems the scroll compressor may be fixed or variable capacity using digital unloading or inverter control.
It is found by diving the amount of energy reused by the amount of energy consumed by the data centre overall. Filter-Drier A device within a refrigeration system normally containing a desiccant designed to remove H2O. Your email address will not be published. Avoids release into the environment — an action that is environmentally irresponsible and illegal in many countries.
Back to top V. Although any size of unit could be defined as a split system it normally refers to smaller equipment, specifically air to air heat pumps.
CWR Chilled water return to a chiller. Heat transfer Heat transfer describes the exchange of thermal energy between two interacting media passing through a heat exchanger, such as refrigerants, air and water.
