Summary
as information technology and artificial intelligence technology in central air conditioning, and refrigeration technology popularization and promotion of industries, enabling better product performance and improvement. This article mainly introduces the main components of central air conditioner, classification and working principle and introduces features, structures, and types of control technology of central air conditioner; analysis of central air conditioning control, and control principle diagram. Central air conditioning is processed after a certain amount of air into the Interior in a certain manner, keep the indoor air temperature, relative humidity, cleanliness and speed of flow control within the appropriate range to meet the technology needs of comfort and a special technology. Central air conditioning system is made up of a host (or a refrigeration system or air supply system) through duct supply air or hot water-driven multiple Terminal, to achieve the purpose of indoor air conditioning air conditioning systems. This courses design in accordance with buildings automation central air conditioning fresh air unit control system design common of specification, and standard, detailed set out has load calculation, and air conditioning way of determines, and wind system design, and air conditioning water system design, and hot and cold source programme of determines, and refrigeration unit design, and air conditioning refrigeration construction figure design, content, and to out typical building air conditioning engineering of design instance and the main as courses design with, and has smart learning features of refrigeration air conditioning refrigeration design software.
