Description

one

The installation of air coadiation is well known, which includes a temperature controller and a relative humidity controller in a serviceable room.

In the proposed facility, in order to improve the dynamic characteristics of the temperature control systems and the relative power of the air supply, the flow sensor is installed on the flow duct, which is connected to the relative humidity and temperature controllers through the correction unit.

The invention is illustrated in the drawing, which shows in principle the technological scheme of the automated central air conditioning unit. The automation scheme of the central air conditioning unit consists of two independent automatic control systems for stabilizing the temperature and relative humidity of the room to be serviced 1.

The automatic temperature control system includes a regulator 2, a temperature sensor 3,; clan 4 on the second pre-heating tenon carrier and a slip clutch 5.

The system of automatic regulation of relative humidity consists of controller 6, sensor 7, three-way clanan 8 on cold water and a through valve 9 on

heat carrier of the first preheater. The flow sensor 10 is installed in the supply air duct and is connected to the controllers through the correction unit 11. All actuators are electric with a constant speed of movement,

The automated installation of air conditioning works as follows.

Depending on the amount of heat release in the serviced room, temperature is stabilized by changing the flow rate of the coolant through the second preheater heater or by changing the amount of air supplied. The electric executive mechanisms of the valve 4 and the slip clutch 5 work as a heat exchanger. In quantitative regulation, i.e. when the stabilization of air temperature in

the room is made by changing the amount of supply air, the adjustment of the temperature controllers 2 and relative humidity 6 from the flow sensor 10 is automatically corrected through

block 11 correction. The correction of the automatic adjustment of the regulators 2 and 6 is carried out as follows.

The correction unit 11 converts the signal from the flow sensor 10 into an electrical magnitude, amplifies it with an electronic amplifier, to the output of which electromagnetic relays are connected, each of which is triggered at a certain voltage, i.e. each relay adjusts to a certain supply air flow. Adjustment adjustment is made by changing the gain factors and the time of the isodrome or by adjusting the relative humidity controllers 6 and temperature 2 in accordance with the change in the static and dynamic parameters of the control object and other body-exchange devices with varying amount of iritis air. All necessary commutations for correction settings of the controllers 2 and 6 are performed by the output relays of the correction unit 11. When switching from quantitative regulation to high quality, the correction unit is turned off by the limit switch of the valve actuator. -To 4. Subject of the invention: The air conditioning unit, including temperature and relative humidity controllers of the room served, differs in that in order to improve the dynamic characteristics of temperature control systems and relative humidity when changing the amount of supply air, a flow sensor is installed on the supply air duct, which through a correction unit is associated with relative humidity and temperature controllers.
