(1) freon compressing unit system (temperature, resh air requirement regulates)

Air-conditioning is when making refrigerating operaton, the refrigerant gas of low-temp low-pressure pressurizes after being sucked by compressor and becomes the refrigerant gas of High Temperature High Pressure, the refrigerant gas of High Temperature High Pressure heat release in outdoor heat exchanger (being condensed by condenser) becomes the liquid (heat is taken away) of middle temperature high pressure by outdoor circulation air, the liquid of middle temperature high pressure is then through the liquid becoming low-temp low-pressure after throttle part reducing pressure by regulating flow, the liquid refrigerant of low-temp low-pressure absorbs heat in indoor heat exchanger, and (room air is through the cooled cooling of heat exchanger surface for the gas that becomes low-temp low-pressure after evaporation, reach the purpose making indoor temperature decline), the refrigerant gas of low-temp low-pressure is sucked by compressor again, so circulation.

The refrigerant gas of low-temp low-pressure pressurizes after being sucked by compressor and becomes the refrigerant gas of High Temperature High Pressure, the heat release in indoor heat exchanger of the refrigerant gas of High Temperature High Pressure become in temperature high pressure liquid (room air through heat exchanger surface be heated, reach the purpose making indoor temperature raise), the liquid of middle temperature high pressure is then through the liquid becoming low-temp low-pressure after throttle part reducing pressure by regulating flow, the liquid of low-temp low-pressure absorbs heat in heat exchanger and becomes the gas (outdoor air through heat exchanger surface cooled cooling) of low-temp low-pressure after evaporation, the gas of low-temp low-pressure is sucked by compressor again, so circulation.

(2) oxygen generator

Molecular sieve oxygen generation equipment is with zeolite molecular sieve for adsorbent, with the equipment (hereinafter referred to as oxygenerator) of pressure swing adsorption method (PressureSwingAdsorption is called for short PSA) oxygen producing.This equipment is with air for raw material under Room-temperature low-pressure, oxygen (accounting for 21%) in air is directly separating by the method for physics, thus producing highly purified medical oxygen, the oxygen concentration produced is 90%～96%, it is characterized in producing oxygen fast, safety, economical, convenient, easily replace bottled oxygen in the past and chemical oxygen generation.Progressively popularization and application at home in recent years.

Oxygenerator operation principle: utilize molecular sieve physical absorption and desorption technique. filling molecular sieve in oxygenerator, can by nitrogen adsorption in air when pressurization, remaining unabsorbed oxygen is collected, and namely becomes highly purified oxygen after purified treatment.The nitrogen discharge adsorbed is returned in surrounding air when decompression by molecular sieve, upper once pressurize time again can absorption nitrogen oxygen producing, whole process is periodically dynamic circulation process, and molecular sieve does not consume.

PSA (pressure-variable adsorption) the air-separating oxygen-making technology that the Dou Shi world that current all oxygenerators adopt is advanced, it be based on attractant (zeolite molecular sieve) to oxygen in air, N2 adsorption ability difference to realize the separation of oxygen, nitrogen.When air enters the bed equipped with adsorbent, adsorption capacity for nitrogen is adsorbed more by force, and oxygen is not adsorbed, and so can obtain the oxygen of high concentration at the adsorbent bed port of export.Owing to adsorbent has the pressure-dependent characteristic of its adsorbance, change its pressure, can make absorption hocket adsorption and desorption operation.

Adopting Skarstrom to circulate two (i.e. two molecular sieve towers) oxygenerator forms, work process is as follows:

Air enters compressor through filter, and compression air enters people adsorber A, B by rotating separation valve and carries out adsorbing separation, controls system and controls seperating vale change adsorption cycle, and distributes air inlet and flow direction of exhaust gases.A circulation in process, compression air enters people adsorber A, now changeover valve is opened, nitrogen in air is adsorbed in the molecular sieve in adsorber, oxygen is flowed out by the threeway of adsorber top, a part is in the adsorber B of desorption state for blowback, and another part exports through fine screen tower and effusion meter.Before adsorber A Middle molecule sieve reaches to adsorb saturated critical state, controller is by valve closing, and air inlet is switched to adsorber B, and desorbing of simultaneously adsorber A being reduced pressure, stripping gas (waste gas richness nitrogen) separated valve is discharged.Adsorber B work process is identical with adsorber A, and the two alternation completes to produce continuously oxygen.

Molecular-sieve type oxygen generator refers to based on pressure-variable adsorption (PSA) technology, extracts the novel device of oxygen from air.It utilizes molecular sieve physical absorption and desorption technique to load molecular sieve in oxygenerator, can by nitrogen adsorption in air when pressurization, and remaining unabsorbed oxygen is collected, and namely becomes highly purified oxygen after purified treatment.Specific works process after air purification drying machine purifies, enters adsorption tower by switching valve for compression air.In adsorption tower, nitrogen is by molecular sieve adsorption, and oxygen enters oxygen storage tank after adsorption tower top is built up, and then through eliminating the unusual smell, dust removal filter and sterilizing filter filter and namely obtain qualified medical oxygen.

Molecular sieve is a kind of crystalline aluminosilicate, and its atom is by certain shaped formation, and basic structural unit is the tetrahedron that four oxygen anions are formed around a less silicon or aluminium ion.Sodium ion or other cationic effect are the deficiencies supplementing aluminum-oxygen tetrahedron positive charge.Each of four oxygen anions, all divides again and is shared by another alumina or silicon-oxy tetrahedron, make lattice make three-dimensional extension.The cation exposed in lattice makes molecular sieve have higher absorbability, and these cationes play a part the strong positive charge lattice point in local, and the female end of polar molecule is carried out electrostatic attraction, and the dipole moment of molecule is more big, is attracted and adsorbs more firm.Under the impact of the strong positive charge in local in cation, molecule can be subject to electromagnetic induction and produce even square.Oxygen and nitrogen all have a quadrupole moment, but the quadrupole moment of nitrogenCompare oxygenRatio is much bigger.Therefore, the active force between nitrogen-atoms and cation is relatively strong, and is preferentially adsorbed.When there being pressure, molecular sieve can adsorb more nitrogen-atoms；When decompression, the nitrogen-atoms of absorption can be discharged (being called desorbing) by molecular sieve.

Main material is constituted: oxygen module: zeolite molecular sieve, oilless (oil free) compressor, rotating separation electromagnetic valve, radiator.

(3) PM2.5 filter

PM2.5 refers to the diameter particulate matter less than or equal to 2.5 microns in air, also referred to as entering lung particulate matter.Its diameter is less than the 1/20 of the hairline thickness of people.Although PM2.5 is the component that in earth atmosphere composition, content is little, but air quality and visibility etc. are had important impact by it.Compared with thicker Atmospheric particulates, PM2.5 particle diameter is little, remote rich in substantial amounts of poisonous and harmful substances and time of staying length in an atmosphere, fed distance, thus the impact of health and atmosphere quality is bigger.On December 5th, 2011, " ambient air quality " (secondary exposure draft) solicits public opinion cut-off, and new standard intends 2016 to implement in full.Jing-jin-ji region, the Yangtze River Delta, three regions, Pearl River Delta and nine groups of cities may be forced the data that requirement is monitored in advance and announced PM2.5.

High efficiency particulate air filter used in the present invention adopts ultra-fine fibre glass paper to make filtrate, and fragmenting plate made by the material such as offset paper, aluminum film, forms with wooden frame aluminium alloy gluing, all tests through receiving flame method, has the features such as filter efficiency height, resistance is low, dust containing capacity is big for every.

In air conditioning system, each fillter section should set monitoring device of resistance.According to whether whole resistance determines filter replacement.Also dependent on experience, according to practical situation, adjust in good time and change whole resistance.Efficient filtration device generally uses crude fibre filtrate, and Inter-fiber voids is big, and the laying dust on filter is likely dispelled by excessive resistance, in this case, filter resistance no longer increases, but filter efficiency drops to almost nil, therefore strictly to control the whole Resistance Value of low efficient filter.

Determine that whole resistance to consider several factor.Fixed low of whole resistance, service life is short, and long-term renewal cost (filter expense, labour cost, and waste treatment expense) is corresponding just high, but operation energy consumption is low, and therefore every kind of filter should have most economical whole Resistance Value.Filter is more dirty, and resistance increases more fast.Too high whole resistance does not mean that filter can extend service life, crosses high-drag and air conditioning system air quantity can be made to fall sharply.Too high whole resistance is worthless.

(4) humidistat

Air dewetting:

Air-conditioning air enters cooler, reduces air themperature and reaches supercooled state, it is achieved thereby that reduce the purpose of temperature and dehumidifying；But too low air temperature can not meet the requirement of human comfort, so air is carried out again heat treatment to reach the requirement of temperature and humidity.Thermal process again in system adds the waste of the energy beyond doubt, adds the load of whole compression refrigerating apparatus, improves the operating cost of air conditioning system.Meanwhile, atmospheric effect be result also in the deterioration of environment by the fluorochlorohydrocarbon cold-producing medium used in systems.In addition, condensation water is had to occur when cooling and dehumidifying, it is easy to cause bacteria breed to affect indoor air quality [1].

From the viewpoint of environmental conservation, saving the energy and air quality etc., solid dehumidifying air conditioning system is a kind of air regulative mode having very much development potentiality and Research Significance.Solid drier, mainly with runner for carrier, makes air to be dehumidified be dried agent moisture absorption through runner, thus reaching the purpose of dehumidifying.Hybrid Air Condition Using Desiccant mainly has advantage:

1. this system reduces the amount of steam mainly by solid drier (lithium chloride, silica gel etc. [2]) and steam generation physics, chemical reaction thus reaching the purpose [3] of dehumidifying.Compared with conventional compression formula air conditioning system, save and cool air to dew point temperature and carry out dehumidifying the refrigerating capacity of this stage many consumption；

2. in the dehumidification process of this system, do not use fluorochlorohydrocarbon cold-producing medium, only used air, steam and solid drier, thus eliminating the fluorochlorohydrocarbon cold-producing medium destruction to ozone layer in dehumidification process；

3. this system can realize the independent control of air themperature and humidity, it is possible to meets the needs of multiple use, expands the use occasion of system, improves the importance of system；

4. less demanding to renewable sources of energy grade of this system; therefore the energy that thermal regeneration gas consumes can adopt the low-grade heat sources [4] such as solar energy, geothermal energy, combustion gas (natural gas, liquefied petroleum gas, coal gas, biogas etc.), industrial exhaust heat; thus decreasing the consumption of mass energy; effectively reduce and low grade heat energy is entered the thermal pollution that air causes, protect environment；

5. the temperature and humidity separate regulation of this system, compared with the kind of refrigeration cycle of conventional air conditioning system, its evaporating temperature can be high, therefore can improve COP and the thermodynamic perfect degree of kind of refrigeration cycle.

Process new wind by rotary wheel dehumidifying and undertake indoor humidity load, indoor humidity, indoor sensible heat refrigeration duty and new wind sensible heat refrigeration duty can be efficiently controlled and undertaken by the dry coil pipe such as ceiling radiant panel or dry-type fan coil, indoor temperature can be efficiently controlled.Humidity and temperature are independently controlled by Rotary Desiccant Wheel Based Hybrid Air Conditioning, efficiently solve the deficiencies such as the traditional air-conditioning system change being difficult in adapt to heat moisture ratio.

Rotary dehumidifier is as one of critical piece that the carrier of solid drier is solid dehumidifying air conditioning system, also being the effective tool of air dewetting, it utilizes the steam in the excellent hydrophilic absorbed air of the dehumidizer such as silica gel, lithium chloride to reach dehumidifying and to meet the purpose of humidity requirement.Rotary dehumidifier is made up of desiccant wheel, actuating device, blower fan, filter, regeneration electric heater etc..Its agent structure desiccant wheel is a dry runner constantly slowly rotated, and adopts the special composite heat resistance material being loaded with solid dehumidifying agent to make.Runner inner-use clapboard is divided into two fan sections [5] of 270 ° and 90 °.270 ° of fan sections are for dried humid air, and 90 ° of fan sections are used for the regeneration of dehumidizer.At normal temperatures, when humid air enters 270 ° of fan sections, owing to the steam partial pressure in dehumidizer is lower than the steam partial pressure in humid air, so the hydrone in air is absorbed by the dehumidizer in runner, dried dry air is sent by blower fan and is carried out sending into air-conditioned room when cooling process reaches suitable temperature.Can be outdoor new wind entirely through the humid air of dehumidification treatments, it is also possible to be the mixing of outdoor new wind and indoor return air.The runner sector absorbing moisture proceeds to 90 ° of regeneration sectors, the regeneration air of high temperature is passed into regeneration sector, now the steam partial pressure in dehumidizer is higher than the steam partial pressure in regeneration air, so the hydrone in dehumidizer enters in regeneration air and is pulled away, recover the wettability power of dehumidizer.Regeneration air can make outdoor new wind, it is also possible to is the mixing of outdoor new wind and indoor exhaust wind, or is indoor exhaust wind entirely.

In rotary dehumidifier, between dehumidification process and the air in regenerative process and dehumidizer, there occurs the heat and mass transfer process of complexity.After the parameter of solid dehumidifying material of rotary dehumidifier and the structural parameters of desiccant wheel are determined, the performance of dehumidifier nevertheless suffers from flow and the runner rotating speed etc. of the flow regeneration air of the inlet condition parameter of dehumidified air, the inlet condition parameter of regeneration air, dehumidified air and is permitted multifactorial impact.The not concrete performance studying certain desiccant wheel of the present invention, but rotary wheel dehumidifying technology is dissolved in the middle of the design of air conditioning to concrete building, designs multiple air-treatment scheme and calculating is compared and drawn preferred plan therein.
