Specific implementation mode
Fig. 1 is direct-expansion type fluorine (R) system, and 100 system containing A of air-conditioning system mainly handles sensible heat load, that is, cools down, B system
Main processing latent heat load, that is, dehumidify, A system 106A containing compressor, evaporator the 104A (heat exchange for cooling down to air
Device), condenser 101A, throttle structure 102A, condenser fan 103A, evaporator fan 105A and refrigeration piping and attachment etc., B
System 106B containing compressor, evaporator 104B (heat exchanger for carrying out cooling and dehumidifying to air), condenser 101B, throttle butterfly
Structure 102B, condenser fan 103B, evaporator fan 105B and refrigeration piping and attachment etc..The refrigeration principle of two systems is to know altogether
Compression-type refrigeration principle, i.e., by compressing air MA cooling of the refrigeration by A systems, by the air SA dehumidifying of B system, SA can be
Room air can also be by the processed air of A systems, as shown in Figure 5.
One typical case of A systems is exactly currently used room air conditioner, and A systems are similar to existing room air conditioner
Device, B system are depth dehumidification system, allow frosting in dehumidification process, and have defrosting measure, that is, utilize the water in B system air inlet
Steam condensation heat and sensible heat carry out defrosting, realize that the dynamic equilibrium of dehumidifying and defrosting, the dynamic equilibrium change air by wind turbine
State realizes that i.e. wind turbine 105B is direction-changeable two-way blower fan, or is the adjustable wind turbine of air quantity, or is the adjustable two-way wind of air quantity
Machine.
The energy balance of cryogenic refrigeration dehumidification process is as follows：
Q=H+h+q
That is refrigerating capacity Q is equal to vapor condensation heat H, in addition water becomes the heat of solidification h frosted, adds the sensible heat of air cooling-down
q；
Conventional freeze drying defrosting is to introduce external heat source, and a kind of situation is to interrupt refrigeration, external world's input heat defrosting；
The present invention makes full use of vapor condensation heat to be more than the solidification thermal property that water change frosts and utilizes vapor during defrosting
Condensation heat defrosting, i.e.,：
H+q=Q+h,
Generally air sensible is seldom, can be ignored, equation is then
H=Q+h,
That is the heat of solidification h that vapor condensation heat H is equal to water adds refrigerating capacity q, defrosting while dehumidifying, while reducing refrigeration
Amount.
The present invention is in dehumidification process, and by processing gas, alternately variation and/or cooling fluid alternately change or handle gas
Body replaces variation with cooling fluid, realizes the balance that frost and defrosting are produced in dehumidification process.Such a balance needs not only to
The variation of amount will also have the variation in temperature field, generate enough heat transfer temperature differences.
The alternating variation of the processing gas includes that processing gas flows through the flow of gas/heat exchange device as flowed
To alternating variation, the alternating variation of processing gas flow and processing gas enter the initial shape of gas/heat exchange device
The alternating of state changes；Alternately variation includes cooling media flow in gas/cooling media heat exchanger to the cooling fluid
Alternately change, the alternating variation of cooling fluid flow and the alternating of cooling fluid temperature change.
For low temperature environments such as refrigerator, refrigerator-freezer, freezers, B system is independently operated, without A systems, is removed using depth of the present invention
Wet system, i.e. B system handle sensible heat load and latent heat load simultaneously, realize that low temperature environment is adjusted.
A, B system can also not only be heated with refrigerated dehumidification, can be converted and be carried out by four-way valve (not shown)
Heating.
The system fully considers the difference of thermic load and humidity load, for refrigeration cool-down, due to the cold-storage in room
Keep the temperature extremely limited, and thermic load changes greatly, so match A systems by larger thermic load, including instrument size and corresponding
Air quantity and cold, while by technological means such as frequency conversions, changing freon evaporating temperature and flow to adjust load, due to spike
Duration of load application is short, and the plenty of time can improve refrigeration system COP by increasing evaporating temperature.The evaporating temperature of A systems can be 5
It is run between DEG C -20 DEG C, when evaporating temperature improves, the COP of system and the cold of unit fluorine flow greatly improve, from minimum
Temperature is to maximum temperature, and amount of energy saving is up to 30%.
For dehumidifying, for opposite cold-storage heat-preserving, room, which has, preferably stores wet humectant properties, in addition, room needs to connect
Continuation of insurance card humidity with ensure building and equipment environment (and air-conditioning temperature-reducing can nobody when stop), so, for B system
Speech continuously at full capacity or heavy-duty service, and can store dry air when load is low, with secondary balanced load, such B systems
The dehumidifying energy of system unit interval is one average value of foundation rather than peak load value, simultaneously because depth dehumidifies, the two knot
It closes so that the instrument size of B system and corresponding air quantity and cold are significantly smaller than A systems.
By taking a typical room air conditioner application as an example, for the A systems of an air quantity 500m3/h, the air quantity of B system
About 30m3/h, about the 1/20 of A systems.
Certainly, this also depends on different applicable cases and requirement, and such as to high Humid Area, room seals bad, wet infiltration
When measuring big, need to increase B system air quantity, but still far smaller than A systems, it is, in general, that B system air quantity is about the 1/ of A systems
5-1/20。
For the evaporating temperature of B system generally in -10 degree to 0 degree, the water capacity of air is 2-6g/kg dry air after dehumidifying, is removed
Moisture is 5-10g/kg dry air.It is low due to removing wet temp, it can effectively inhibit mould generation or killer bacterium, in addition B system
The production heat exchange surface of dehumidifying be far smaller than A systems cooling do surface, finally, as previously mentioned, B system continuously at full capacity or
Heavy-duty service persistently ensures the drying in room.The system of the present invention is made to have the characteristics that good restraining and sterilizing bacteria at 3 points above,
Provide a kind of healthy air-conditioning system.
Since the cold of the micromation of B system, while A systems is improved with the raising of evaporating temperature, of the invention is
For system compared with existing system, volume and cost are substantially suitable, it could even be possible to it is lower, its application is thus significantly facilitated, is wrapped

23, such as solar energy.
The system can rapid frost melting, the defrosting time (i.e. above-mentioned first process) is generally -90 seconds 30 seconds, according to different gas
Time condition, defrosting interval (i.e. above-mentioned first process) is generally -90 minutes 30 minutes, since the defrosting time is short, the storage of accumulator
Minimum energy, for the heat pump of a 3kW, accumulation of energy amount also only has 15-75Wh that salt may be used so energy-accumulation material is few
Liquid or phase-change material, quantity of material are about 0.3-2kg, simultaneously because the accumulation of energy time is long, the power of accumulation of energy is minimum, even if using electricity
Heating, power is about 30W-50W, if using the heat of heat pump itself when for heat pump, the influence to heat pump also can be ignored.
Due in heat exchanger cooling fluid must not heat or hot very little, electrothermal vapor device power also very little consider cooling
For fluid in the second process all by accumulator, the steam that electrothermal vapor device generates also only needs the condensation heat for overcoming frost to become water
Consider that frost amount is 0.05- for the heat pump of a 3kW with the heat of evaporation for the cooling fluid retained in Tube Sheet of Heat Exchanger
0.1kg, about 15Wh. electrothermal vapors device power is about 500W-1000W.
