Ventilation is the process of changing or replacing air in any
space to control temperature or remove any combination of
moisture, odors, smoke, heat, dust, airborne bacteria, or
carbon dioxide, and to replenish oxygen. Ventilation includes
both the exchange of air with the outside as well as circulation
of air within the building.
Air conditioning and refrigeration are provided through the
removal of heat. Heat can be removed through radiation,
convection, or conduction. Refrigeration conduction media
such as water, air, ice, and chemicals are referred to as
refrigerants. A refrigerant is employed either in a heat pump
system in which a compressor is used to drive thermodynamic refrigeration cycle, or in a free cooling
system which uses pumps to circulate a cool refrigerant (typically water or a glycol mix).
Building Management System (BMS)
A Building Management System (BMS) is a computer-based control system installed in buildings that
controls and monitors the building’s mechanical and
electrical equipment such as ventilation, lighting, power
systems, fire systems, and security systems. A BMS
consists of software and hardware; the software
program, usually configured in a hierarchical manner,
can be proprietary, using such protocols as C-bus,
Profibus, and so on. Vendors are also producing BMSs
that integrate using Internet protocols and open
standards such as DeviceNet, SOAP, XML, BACnet,
LonWorks and Modbus.
