Description

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

The aim of the invention is to increase the degree of utilization of heat energy of the coolant.

The drawing is a schematic diagram of the air conditioning system,

The air conditioning system contains an air conditioner 2 communicated by inlet 1 with the atmosphere, having successively located along the process air, first and second stages 3 and 4 of heating, and heaters 7 of the willows located in room 6 parallel to the outlet 5 of the air conditioner 2

The first and second heat exchangers 9 and 10 are connected in parallel to supply and return pipelines 11 and 12 and are connected respectively to the second heating stage 4 and heaters 7 and 8 with the formation of the circulation circuit 13 of the intermediate heat carrier and the circulation ventilation circuit 14,

The heat utilizer 1.5 is installed at the outlet 6 of the air from the room 6 and connected with the recycling circuit 17 to the first heating stage 3

The first heat exchanger 9 is connected to the return pipeline 12 through the heat carrier temperature controller i 8,

The first additional heat exchanger 19 is installed in the liquid circuit 14 at the inlet 20 of the second heat exchanger 10 and its inlet 21 is connected through the heat transfer fluid through the pump 22 to the return pipeline 12, and the outlet 23 to the inlet 24 of the second additional heat exchanger 25,

The second additional heat exchanger 25 is installed in the inlet circuit 17 at the inlet 26 of the first heating stage 3, and its outlet 27 is connected to the return pipeline 12.

The second regulator 28 of the coolant temperature is installed at the outlet 29 of the second ten-unit control unit 10, and the regulator .3 O of the coolant pressure at the outlet 27 of the second additional heat accumulator 25.

 Return pipe 2 is compensated, the th washer 31, located between the points of connection to it

heat exchangers 19 and 25.

The air conditioning system operates in track K1P1.

The supply line 1 1 hot water enters the first and second heat exchangers 9 and 10. The first heat exchanger 9 provides heating of water, which is then fed to the second heating circuit through the circulation loop 13 of the intermediate heat transfer fluid, and the second heat exchanger 10 provides heating of water which is then fed through the liquid circuit 14 to the heaters 7 and 8d. From the first and second heat exchangers 9 and 10, water returns to the return pipe 12, which is controlled by the heat carrier temperature regulators 18 and 28 In terms of the temperature of the coolant returned to the return pipeline 12,

In order to increase the use of heat energy of the heat transfer fluid, the additional heat exchangers 19 and 25 are additionally sequentially supplied from the return pipe 12 to the first and second heat exchangers 19, and then

By arranging in the return pipe 12 of the compensation washer 31 and using the regulator 30 of the pressure 35 of the coolant lazer, the normal operation of the pump 22 is ensured,

The outside air is taken in by air conditioning 2, for example, from the atmosphere, warmed up in the first and second stages - 40 pen x 3 and 4, undergoes additional processing in heaters 7 and 8 and is distributed in room 6

Exhaust air is removed from room 6 through exit 16 and heat exchanger 15,

When the outdoor air temperature rises and the heat demand for heating is reduced and the supply air is heated, adjustments 18 and 28 of the coolant temperature limit the flow of coolant from the direct supply pipe 11 and

55 more complete use of the thermal potential of the heat carrier in the first and second additional heat exchangers 19 and 25,
