tt

Изобретение относитс к вентил ци и может быть использовано в помещени х со значительными теплоизбытками .The invention relates to ventilation and can be used in rooms with significant heat losses.

Известна система вентил ции помещений с вредными тепловыделени ми, содержаща теплообменник-утилизатор и подключенные к нему воздуховоды дл приточного и выт жного воздуха 1.A known ventilation system for rooms with harmful heat generation, comprising a heat exchanger-heat exchanger and air ducts connected to it for supply and exhaust air 1.

Недостаток этих систем - неполное использование внутренних теплоизбытков дл нагрева холодного воздуха , так как дл осуществлени подпора в помещении требуетс подавать большёэ приточного воздуха, чем удал ть из него, что приводит к дополнительному подогреву приточного воздуха и, следовательно, к перерасходу тепла.The disadvantage of these systems is the incomplete use of internal heat surpluses for heating cold air, since in order to maintain the pressure in the room it is required to supply more supply air than to remove from it, which leads to additional heating of the supply air and, consequently, to heat waste.

Наиболее близкой по технической сущности и достигаемому эффекту к предлагаемой вл етс система вентил ции помещений с вредными тепловыделени ми , преимущественно животноводческих , содержаща теплообменникутилизатор и подключенные к нему приемные камеры наружного и внутреннего воздуха, снабженные окнами и выходными патрубками, приточныйThe closest to the technical essence and the achieved effect to the proposed is the ventilation system of rooms with harmful heat generation, mainly livestock, containing a heat exchanger utilizer and external and internal air receiving chambers connected to it, equipped with windows and outlets,

Однако и в этой системе дл нагрева дополнительного приточного воздуха требуетс дополнительна систе0 ма подогрева.However, in this system, additional heating is required for heating additional supply air.

Claims

5 pipeline - with a zone of increased concentration of heat. The reddening window, the window of the internal air chamber, has an area 2-5 times larger than the window area of the outdoor air chamber. The drawing shows a diagram of the ventilation system. The ventilation system of the rooms with harmful heat emissions, mainly livestock, contains a heat exchanger 1 and connected to it the receiving chambers 2 and 3 of the outside and the inside air equipped with windows .-- and 5 and outlet pipes 6 and 7, inlet duct 8, connected with the outlet pipe of the outdoor air chamber 2, the air intake air inlet 9 with a hole 10 for air intake, the air inlet pipe 11 and the air temperature sensor 12; the air intake plenum 9 and the piping 11 are connected to the outlet 7 of the internal air chamber 3, and in the windows 4 and 5 of the receiving chambers 2 and 3 and in the opening 10 of the plenum 9 are installed valves 13-15 with actuators 16 connected to the sensor 12 temperature control, with the supply air duct 8 communicating with the working area of the room, and the supply air pipe 11 with the zone of increased concentration of heat release. The window 5 of the chamber 3 of the internal air has an area exceeding by 2-5 times the size of the window 4 of the chamber 2 of the outer air. The system has an exhaust shaft 17. The outlet nozzles 6 and 7 are connected to the intake duct 8 and the pipeline 11 by means of fans 18. The exhaust duct 19 is connected to window 5 of the receiving chamber-g rya 3 of the internal air. The ventilation system works as follows. In the cold period of the year, through the window 4, the minimum amount of outside air enters the receiving chamber 2 of the heat exchanger 1 and is calculated according to the conditions for ensuring the standardized gas composition of the indoor air in the room. At the same time, in the air inlet 10 of the boron supply shaft 9, the valve 15 is completely closed, and the capstan 14 installed in the window 5 of the receiving chamber 3 of the internal air is fully open and the internal air enters the heat exchanger-heat exchanger 1 through the exhaust duct 19. Since Since the air has a higher temperature than the outside temperature, heat transfer from the internal air to the external air is ensured in the heat exchanger 1. At low ambient temperatures, the indoor air in the room in the heat exchanger 1 is dried, as condensate is released from it. At the exit of the receiving chamber 2, the heated air in the heat exchanger 1 utilizes the supply air duct 8 to the working area of the room, and dried and cooled in the heat exchanger the utilizer 1 internal air from the receiving chamber 3 of the internal air enters through the inlet pipe 11 into the area of the room with a high concentration of heat targets. During the transitional and warm periods of the year, heat losses in the room increase, which leads to an increase in the internal air temperature of the room, sensed by sensor 12, which pulses through the actuators 16 to close valve 14 in chamber window 5 and open valve 15 in opening 10 of inlet shaft 9. In this mode, the minimum amount of outside air enters the heat exchanger 1 heat exchanger 1 through the window 4 of CAM 2, and the internal and external air enters the outlet 7 through the window 5 and the opening 10, respectively. Since the temperature of the outside air entering the heat exchanger utilizer 1 is significantly lower than the temperature of the air mixture entering the outlet nozzle 7, the temperature and moisture content of the air mixture also decreases. During the warm period of the year, only the outside air passes through the heat exchanger 1, while the valve 14 closes the window 5, and the valve 15 opens the opening 10 of the inlet shaft. The supply air through the opening 10 enters the outlet 7 and through the pipeline 11 into the zone of the highest concentration of heat release in the room. There is a slight increase in the pressure of the indoor air in the room, and under the influence of overpressure, the exhaust shaft 17 opens. Thus, the proposed implementation of the system makes it more economical. Claim 1.
