The poison filtering device is the core equipment for various nuclear biochemical protection. However, the existing toxicity filtering device based on the activated carbon adsorption effect generally has the problems of limited protection duration, incomplete protection pedigree, short storage period, difficulty in disposal after adsorption and the like, so that the device has poor effectiveness, economy and maintainability in actual use, and is difficult to meet the modern long-term and full-effect protection requirements. People, as a main body of nuclear biochemical protection, need to provide a proper temperature and humidity environment in addition to supplying clean air. However, the isolated collective protection system developed in the early stage is used for carrying out closed treatment on protection engineering so as to isolate nuclear biochemical pollution in the external environment, and such a protection mechanism inevitably causes deterioration of environmental conditions such as indoor oxygen, carbon dioxide concentration, temperature and humidity and the like, and influences physical and psychological health of personnel. In conclusion, the research and development of advanced toxin filtering, ventilation and environmental control technologies are important technical problems to be solved for ensuring that people can deal with various sudden nuclear biochemical events.

In order to solve the above problems, the present invention provides a heat and mass cooperative transmission air conditioning circulation system based on oxygen selective absorption and release, comprising:
the refrigerating circulation loop comprises a typical evaporator, a compressor, a condenser, a throttle valve and corresponding pipeline accessories, and is filled with a refrigerant, and the oxygen/carbon dioxide conveying loop comprises 2 sets of gas-liquid separation heat and mass exchangers, a pump, a flow regulating valve and corresponding pipeline accessories. An artificial oxygen carrier with selective absorption and release capacity to oxygen and carbon dioxide is filled in the oxygen/carbon dioxide transport loop; the 2 sets of gas-liquid separation heat and mass exchangers realize the selective absorption and release of oxygen/carbon dioxide by carrying out cold and heat exchange with corresponding evaporators and condensers.
Furthermore, the artificial oxygen carrier is easy to generate oxygenation effect with oxygen under the condition of lower temperature, and is easy to generate dissociation effect with oxygen under the condition of higher temperature; the binding and dissociation effects of carbon dioxide are reversed.
Furthermore, the 2 sets of gas-liquid separation heat and mass exchangers are respectively arranged outdoors and indoors, and realize the selective absorption and release of oxygen/carbon dioxide through the cold-heat exchange with the corresponding evaporator and condenser in the refrigeration cycle loop.
Further, the outdoor gas-liquid separation heat and mass exchanger and the evaporator realize heat exchange through a heat exchange loop, so that oxygen is absorbed from the outdoor space under a lower temperature condition, and carbon dioxide is released.
Further, the indoor gas-liquid separation heat and mass exchanger and the condenser realize heat exchange through a heat exchange loop, so that carbon dioxide is absorbed from the indoor space under the condition of higher temperature, and oxygen is released.
Preferably, the oxygen/carbon dioxide transport loop controls the transport of oxygen and carbon dioxide by a pump in conjunction with a flow control valve.
Preferably, the oxygen/carbon dioxide transport loop controls the heat exchange amount of the gas-liquid separation heat exchanger through a pump and a flow regulating valve together, so that the temperature of the heat exchanger is regulated.
Preferably, the gas-liquid separation heat and mass exchanger is composed of a membrane material with a high selective separation coefficient for oxygen, a supporting framework and heat exchange fins.
Preferably, after the refrigeration cycle loop and the oxygen/carbon dioxide transport loop coupled and circulated with the refrigeration cycle loop control the throttle valve and the flow regulation together through a certain control logic and means, the cooperative control of the indoor temperature, the indoor humidity and the oxygen/carbon dioxide concentration can be realized.
Compared with the prior art, the invention adopts an integrated design, couples the refrigeration cycle with the toxin filtering ventilation control cycle, and forms a set of heat and mass cooperative transmission air conditioning system. The system can selectively pump oxygen from the nuclear biochemical polluted environment, pump out indoor carbon dioxide and regulate the temperature and humidity of the indoor carbon dioxide, thereby realizing the effects of constant temperature, constant humidity and constant oxygen in a protection area.
Compared with the conventional filtering type collective protection system, the system has the following advantages:
1) only selectively absorb oxygen from the outdoor, and have super-strong broad-spectrum protection;
2) the condition of adsorption saturation does not exist, and the full-time protection capability is realized;
3) only the absorbed oxygen is subjected to heat exchange, and the energy consumption of a system for treating the replacement air is low;
4) the dynamic balance of indoor oxygen and carbon dioxide can be realized;
5) the phenomenon of wind cross is avoided, and the problem of mutual contamination of nuclear and biological materials in the interior caused by leakage of partial protection areas can be avoided. Besides the collective protection system, the novel system is also expected to be applied to a submarine or airborne environment control system. In addition, the scheme is also very suitable for civil markets such as indoor environment control of buildings, vegetable and fruit preservation and the like.

The oxygen/carbon dioxide transport loop is filled with artificial oxygen carriers with selective absorption and release capacity on oxygen and carbon dioxide, and the artificial oxygen carriers are easy to generate oxygenation effect with oxygen at lower temperature and dissociation effect with oxygen at higher temperature; the binding and dissociation effects of carbon dioxide are reversed.
The 2 sets of gas-liquid separation heat and mass exchangers 5 are respectively arranged outdoors and indoors, and realize the selective absorption and release of oxygen/carbon dioxide through the cold-heat exchange with the corresponding evaporator and condenser in the refrigeration cycle loop.

Preferably, the oxygen/carbon dioxide delivery circuit controls the delivery of oxygen and carbon dioxide by means of a pump 6 in conjunction with a flow control valve 4.
Preferably, the oxygen/carbon dioxide transport loop controls the heat exchange amount with the gas-liquid separation heat and mass exchanger through the pump 6 and the flow regulating valve 4 together, so as to realize the temperature regulation of the heat and mass exchanger.

Preferably, after the refrigeration cycle loop and the oxygen/carbon dioxide transport loop coupled and circulated with the refrigeration cycle loop control the throttle valve and the flow regulation together through a certain control logic and means, the cooperative control of the indoor temperature, the indoor humidity and the oxygen/carbon dioxide concentration can be realized.
Specifically, as shown in fig. 2: when the collective protection area is attacked by external nuclear biochemistry, the refrigeration cycle loop is started to regulate the temperature and the humidity in the closed room. Meanwhile, part of cold energy of the evaporator 7 is transmitted to the outdoor gas-liquid separation heat and mass exchanger 5 through a temperature coupling pipeline, and is adjusted to a proper temperature through the flow regulating valve 4 and the pump 6, so that the oxygenation effect of outdoor oxygen is promoted. Accordingly, a part of the heat temperature coupling pipe of the condenser 2 is delivered to the indoor gas-liquid separation heat and mass exchanger 5 and is adjusted to a proper temperature by the flow rate adjusting valve 4 and the pump 6, thereby promoting the dissociation effect of the outdoor oxygen. Finally, the combined action of the pump and flow regulating valve in the oxygen/carbon dioxide circulation loop selectively pumps outdoor oxygen to the room and pumps excess carbon dioxide from the room to the outside, thereby continuously providing a clean air environment for regional personnel.
In conclusion, the invention adopts an integrated design, and couples the refrigeration cycle with the toxin filtering ventilation control cycle to form a set of heat and mass cooperative transmission air conditioning system. The system can selectively pump oxygen from the nuclear biochemical polluted environment, pump out indoor carbon dioxide and regulate the temperature and humidity of the indoor carbon dioxide, thereby realizing the effects of constant temperature, constant humidity and constant oxygen in a protection area.
