Description

The invention relates to a technique of ventilation and air conditioning.

The aim of the invention is to reduce energy costs and heat recovery of waste water.

FIG. 1 is a schematic diagram of an automated system.

air conditioning; in fig. 2 — node I in FIG. one.

The automated air conditioning system contains heat exchangers 2 sequentially arranged along the air flow in supply air duct 1, irrigation chamber 3 with circulation circuit 4 and pump 5, and air supply fan 6 of central air conditioner 7, the latter of which is connected through air distributors 8 and 9 with room 10.

The devices 11 and 12 of evaporative cooling water have a nozzle 13 and 14 and air outlet pipes 15 and 16. An exhaust duct 17 communicates the room 10 through the ceiling 18 with the atmosphere. The devices 11 and 12 of evaporative cooling water are connected by direct and return pipelines 19 and 20 to heat exchangers 2.

In the inlet duct 1 after the heat exchangers 2, air temperature sensors 21 and 22 are installed along the air path and the room 10, and an additional pump 23 is installed on the return pipe. Under the ceiling 18 of the room 10 are installed with a gap 24 and at different levels of the panel 25, made of thermal insulation of the material and with a reflective coating 26. The output air nozzles 15 and 17 of the apparatus 11 and 12 of the evaporative cooling water communicate through the gap 24 with the exhaust duct 17 and are equipped with air valves 27 and 28 with actuators mechanisms 29 and 30 associated with air temperature sensor 21 after heat exchangers 2.

The direct and return lines 19 and 20 are equipped with on-off valves 31 and 32 and are interconnected by means of a jumper 33 with an additional on-off valve 34.

An additional pump 23 using a magnetic actuator 35 in parallel with the main and additional on-off valves 31, 32 and 34 is connected to the air temperature sensor 21 after the heat exchangers 2, which is adjustable with three levels of its setting.

Heat exchangers 36 and 37 with inlet and outlet pipes 38 and 39, 40 and 41, having valves 42 and 43 with actuators 44 and 45, connected in parallel to sensors 21 and 22 air temperature.

Automated air conditioning system works as follows.

Throughout the year, the air processed in the central air conditioner 7 is supplied by a supply fan 6 to the room 10 through the air distributors 8 and 9.

During the warm period of the year, the temperature in room 10 (its working area) is maintained above the minimum allowable

level using the sensor 22 temperature, the signal which closes the valve 43 and stops the pump 5. In this case, the corresponding signal from

The temperature sensor 21, operating in the given period of the year at the top level of adjustment, starts up the operation of the pump 23, opens the valve 32, closes the valves 34, 42, opens the air valves 27 and

28 and the start-up of the apparatus 11 and 12 of evaporative cooling of water.

The cooled water is supplied by a pump 23 to the heat exchangers 2 of the central air conditioner 7. The cooled and moist air from

the evaporative cooling devices are supplied via air nozzles 15 and 16 to the gap 24 between the panels 25 and the ceiling 18 of the room 10. Exhaust air from the room 10 between the panels 25 also enters the gap 24 and then together with the air from the apparatuses 11 and 12 cooling water through exhaust duct 17 is vented to the atmosphere. The use of panels 25 with a reflective coating 26 also contributes to reducing the flow of heat into the room 10 from the overlap 18 side.

In the transitional period of the year, when heat treatment is not required

air, according to a signal from the temperature sensor 21, the pump 23 stops. In the cold period of the year, the signal from the temperature sensor 21 triggers the operation of the pump 23, closes the valve 32, opens the valves

34 and 42, closing the air valves 27 and 28 and stopping the apparatus 11 and 12 of evaporative water cooling,

As the outside air temperature further decreases, the valve 43 opens and the pump 5 starts to operate. The excess air between the panels 25 enters the gap 24 and is then vented to the atmosphere through the exhaust duct 17.
