Description

The invention relates to the field of air conditioning, namely to air conditioning systems (ACS) of multi-nat. Kondish oshfufashg zozu spirit systems are known, containing air conditioner-closers installed at consumers with heat exchangers connected to the corresponding main pipelines with the help of return inlet pipes for variable flow of cold and heat carrier (non-reversible regulators) through them, installed on the supply lines, and temperature sensors, place a chase in the air recirculation stream l. The disadvantage of these systems is low reliability and low heat and energy efficiency in the implementation of heating, as. Heating is carried out by supplying warm air to the air conditioner closer,. The aim of the present invention is to increase the reliability and heat power efficiency in the implementation of a standby heating mode. The goal is achieved by the fact that the supply lines of the system for heat and cold supply of fine-tuning through non-reversible regulators, made three-way w, are connected with jumpers with return lines, and heaters are installed on one of the lines in the sections that go beyond the jumpers. placed over the last in the zone of action of convective currents created by them. FIG. 1 is a schematic diagram of the following air conditioning system: FIG. 2. - A knot about & heat exchanger air conditioner closer and non-reversible regulator. The air conditioning system contains a central air conditioner 1, a zone heater 2, connected in air by water 3 to the air conditioners-closers 4 with heat exchangers 5 connected with air & power supply lines 6 and return lines 7 to the main pipelines 8 and 9. To change the supply of heat and chopper, on the main pipe 9, there is a pyrtle pump 10 connected to the water cooling

11, Non-reversible regulators 12, made three-way (through them the flow lines 6 using jumpers 13), are connected to the return lines 7. Heaters 15 are mounted on one of the lines in the sections beyond the bridges, and sensors 15 are placed , temperatures in the zone of action of convection flows created by imp. On the pipelines 16 for supplying water to the water cooler 11, control valves 17 and 18 are installed, switching valves 19 and 20. Control valves 17 and 18 are connected to sensors 21 and 22.

The described air conditioning system works as follows.

In the operating mode, air from the central air conditioner 1 through the zone heater 2 through the air duct 3 is supplied to the air conditioner 1 and the air duct 9 M installed, for example, under the window. The water cooled in the cooler 11 by the circulation pump 10 through the flow line 6 is supplied to the heat exchangers 5. The temperature is controlled by the valve 17 and the sensor ch1 21. The valves 19 are open and the valves 20 are closed.

The room air is ejected through the heat exchanger 5 and, .cNfemaBiUHCb with air from the central air conditioner, enters the room. A non-reversible controller 12 at the command of sensor 15 reduces or increases the supply of cold water to the heat sink 5 when the room air temperature is lowered or increased. When this excess amount of water passes through the jumper 13 in the return line 7.

In standby mode, air is not supplied from the central air conditioner. Heat exchangers 5 are supplied with hot water. Its temperature is controlled by a valve 18 and a sensor 22 installed in one of the characteristic premises of the building. At the same time, the valves 2O are open, and the valves 19 are closed.

Heated / heated 14, fed by hot water {its installation is shown on the flow line.

see. FIG. 2), simulates with co-currents for sensor 15, increases room temperature, as a result of which sensor 15 commands the opening of a non-reversible regulator 12 for the flow of hot water through a heat exchanger 5, thereby providing for standby heating.

This invention allows to significantly expand the boundaries of the use of air conditioning systems with air conditioners by the closers and to realize, thereby, the high economic efficiency embodied in these systems. Compared with the limestone system, it is possible to save electricity up to.
