Abstract
A central air-conditioning outdoor oxygen content simulating system comprises an oxygen supply pipeline, a plurality of oxygen content measuring devices and a programmable controller. An outlet of the oxygen supply pipeline is connected to fresh air pipelines of users, and an inlet of the oxygen supply pipeline is connected to an oxygen source or an oxygen production device in common. A manual stop valve 1, a pressure gage 1, a filter, a pressure adjusting valve, a flow transmitter, a stop valve, a flow adjusting valve, a pressure gage 2, a manual stop valve 2 and a check valve are arranged on the oxygen supply pipeline in sequence. The oxygen content measuring devices are arranged at the positions of the users respectively. The programmable controller is electrically connected with the flow transmitter, the oxygen content measuring devices and the flow adjusting valve. Through the application of the central air-conditioning outdoor oxygen content simulating system, air oxygen content similar to that outside the room can be obtained in the central air conditioning environment, and people are prevented from working and studying in oxygen-deficient and anoxic environment.
Description
Technical field
The utility model relates to central air conditioner system, particularly the imitative outdoor air oxygen content system of a kind of central air-conditioning.
Background technology
Center air regulates and is called for short central air-conditioning, and object is to create a suitable room atmosphere environment, makes people feel comfortable in this environment; In order to realize this purpose, the technological means that air conditioning relies on is mainly ventilation, and specifically, the air of processing exactly and process certain mass is sent into indoor, and room atmosphere environment is met the demands.The processing procedure of air is comprised to the processing such as heat (cooling), humidification (dehumidifying), purification.
Central air conditioner system must adopt the outdoor fresh air (being new wind) of a part in running, this part new wind must meet the needed minimum fresh air amount of office work personnel, and therefore the new wind amount of being taken into of air-conditioning system is decided by service purposes and the hygienic requirements of air-conditioning system.
The introducing port of new wind is generally located at pollution-immune place around.The dust filtration device of the introducing port of these new wind and the fresh air pipeline of central air conditioner system and new wind, the VMC that fresh air preheating device has formed central air conditioner system jointly.
During existing central air conditioner system is used, ever-present problem:
1) outdoor content of oxygen in air is generally 20.9%.Use the oxygen content in the room air of central air-conditioning often can be lower than outdoor normal air oxygen content, this be because: A) oxygen the breathe out CO of people in indoor continuous air amount
2, make oxygen-content reduction, CO2 content in room air increase; B) the outdoor new wind that central air conditioner system is supplemented, a normally part for indoor total blast volume.Like this, in the indoor environment of employing central air conditioner system, actual oxygen content is lower than the normal oxygen content of outdoor air.Like this, just make the people that work, learn, the more or less environment in oxygen deprivation and anoxic in central air-conditioning environment.
2) the indoor oxygen content measurement mechanism of not laying, indoor people do not know the actual oxygen content of room air.
3), when haze weather, thermal extremes weather occur, central air conditioner system operating personnel usually can reduce the supplementary ratio of new wind air quantity.
Summary of the invention
The purpose of this utility model is to design the imitative outdoor air oxygen content system of a kind of central air-conditioning, in the environment of central air-conditioning, obtains and outdoor similar air oxygen content, avoids people's working and learning in the environment of oxygen deprivation and anoxic.
For achieving the above object, the technical solution of the utility model is:
Central air-conditioning is imitated outdoor air oxygen content system, and it comprises, oxygen supply pipeline, and its outlet is connected in the new wind airduct at each user place, and import is connected to altogether and connects source of oxygen or oxygenerator; On this oxygen supply pipeline, set gradually 1# hand stop valve, 1# Pressure gauge, filter, pressure-regulating valve, flow transmitter, stop valve, flow control valve, 2# Pressure gauge, 2# hand stop valve, check valve; Some measurement of oxygen content devices, are arranged at respectively each user place; Programmable controller, described flow transmitter, measurement of oxygen content device and flow control valve are electrically connected this controller.
Further, described new wind airduct is established measurement of oxygen content device, and is electrically connected programmable controller.
At the downstream of the blower fan of conventional central air conditioner system access oxygen channel, for the oxygenating of central air conditioner system.Oxygen control pipeline is comprised of hand stop valve, Pressure gauge, filter, pressure-regulating valve, flow transmitter, stop valve, flow control valve, check valve etc.Oxygen in 1# hand stop valve hand switch pipeline, the replacing of being convenient to each components and parts in valve group is safeguarded; The on-the-spot pressure that shows the front oxygen of pressure regulator valve of Pressure gauge; Filter filters the impurity in oxygen; Pressure regulator valve is adjusted to the oxygen pressure in pipeline the pressure needing; Flow transmitter is sent to PLC control system in real time oxygen flow in pipeline; Stop valve in emergency circumstances cuts off oxygen supply; Flow control valve regulates the flow of oxygen in pipeline in real time; 2# hand stop valve: the oxygen in hand switch pipeline, the within the specific limits flow of oxygen in manual adjustments pipeline; Check valve makes oxygen one-way flow.
Measurement of oxygen content device is installed in indoor room, take normal outdoor air oxygen content as benchmark, as 20.9%, the air oxygen content in measuring chamber.When indoor oxygen content is lower than 20.9% time, measurement mechanism sends signal to controller, opens the flow control valve on oxygen pipeline, presses flow proportional, supplemental oxygen with the new wind supplementing.When indoor oxygen content reaches normal, measurement mechanism sends pass stop instruction.Oxygen channel is closed down.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is the A portion enlarged diagram of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, central air-conditioning of the present utility model is imitated outdoor air oxygen content system, and it comprises, oxygen supply pipeline 1, and its outlet is connected in the new wind airduct 200 at each user 100 places, and import is connected to altogether and connects source of oxygen or oxygenerator 2; On this oxygen supply pipeline 1, set gradually 1# hand stop valve 3,1# Pressure gauge 4, filter 5, pressure-regulating valve 6, flow transmitter 7, stop valve 8, flow control valve 9,2 # Pressure gauge 10,2# hand stop valve 11, check valve 12; Some measurement of oxygen content devices 13, are arranged at respectively each user 100 places; Programmable controller 14, described flow transmitter 7, measurement of oxygen content device 13 and flow control valve 9 are electrically connected this controller.
Further, described new wind airduct 200 is established measurement of oxygen content device 13 ', and is electrically connected programmable controller 14.
The measurement of oxygen content measurement device room air oxygen content of installing in indoor room.When indoor oxygen content is lower than when setting value, measurement mechanism sends signal to controller, opens magnetic valve---the flow control valve on oxygen pipeline, presses flow proportional, supplemental oxygen with the new wind supplementing.When indoor oxygen content reaches normal, measurement mechanism sends pass stop instruction, and oxygen channel is closed down.
