One of the main components of modern central airs and ventilation (hard currency) is means and systems of automatic equipment. They realize various functions of management which have to provide on the one hand maintenance of the required microclimate in the served room, and with another - economic and reliable work of processing equipment. Range of the functions of management which are carried out by systems of automatic equipment by quantity and complexity of realization is quite wide: from simple inclusion - switching off before the centralized management of climatic or all engineering equipment of the building .
The main technological functions of management of hard currency are, as a rule, realized at the level of separate installations by means of the systems of automatic control (SAC). SAU are a set of object of management (the operated technological process) and actuation devices which interaction provides automatic course of process according to the set program. At the same time technological process is understood as sequence of operations which need to be executed that from initial raw materials to receive a ready-made product. In case of hard currency a ready-made product is air in the served room with the set parameters (temperature, humidity, gas structure and so on), and raw materials external and exhaust air, heat carriers, the electric power and others.
In a basis of functioning of systems of automatic control of hard currency, as well as any control system, the principle of feedback is put: elaboration of the operating influences on the basis of information on object obtained by means of the sensors installed on object.
Each concrete SAU is developed proceeding from the set technology of processing of an entrance stream of air. It can be simple ventilating systems or the central conditioners in combination with self-contained units (dehumidifiers, independent conditioners, humidifiers).
At use of self-contained units or complete technological installations of processing of SAU air are delivered by the certain functions of management which are already built in the equipment and already put which are usually in detail described in technical documentation. In this case adjustment, service and operation of such control systems have to be made in strict accordance with the specified documentation.
If SAU demands development for the concrete technological scheme and the equipment with installation of means of automatic equipment of other firms in it - producers, then definition of the optimum program and concrete functions of management has to be conducted in common by specialists in conditioning and ventilation and specialists in automation. At such approach are considered as requirements to system of automation, and to the automated object.
