Compared with the prior art, the present invention has the following advantages:
1, the double runner dehumidifier/air-conditioning system of low temperature and low humidity driving of the invention, the second desiccant wheel dehumidifying area are mainly the One desiccant wheel renewing zone provides air inlet, the air draft of the second desiccant wheel dehumidifying area's high temperature low humidity is taken full advantage of in this way, to the The heat of adsorption of two desiccant wheels has carried out recuperation of heat, reduces the temperature heated needed for auxiliary air heater；Reduce first The humidity of desiccant wheel renewing zone import wind increases the partial pressure of the regeneration side and desiccant surface vapor of the first desiccant wheel Difference makes to be desorbed more efficient, the then regeneration efficiency raising of the first desiccant wheel.
2, the double runner dehumidifier/air-conditioning system of low temperature and low humidity of the invention driving, can be made full use of using board-like heat regenerator The air draft of the higher temperature come out from the first desiccant wheel dehumidifying area, carries out recuperation of heat to the heat of adsorption of the first desiccant wheel, right The regeneration air air inlet of lower second desiccant wheel of temperature is preheated, and regeneration heating amount and the processing air for reducing system are cold But it measures, has advanced optimized system.
3, the double runner dehumidifier/air-conditioning system of low temperature and low humidity of the invention driving, surrounding air are carried out by air precooler Pre-cooling reduces the inlet air temperature in the first desiccant wheel dehumidifying area, improves the dehumidifying effect of the first desiccant wheel.
4, the double runner dehumidifier/air-conditioning system of low temperature and low humidity of the invention driving, can be used for two season of summer in winter, be cooling in summer, For Winter heat supply；Very good solution conventional dehumidification runner air-conditioning is suitable for summer, the problem too low for winter efficiency；This is low Sensible heat air conditioning terminal and desiccant wheel system share a Cooling and Heat Source, the cost drop of system in temperature driving double runner dehumidification air conditioner It is low.
5, in of the invention summer the first air-treatment path and the first air-treatment of winter path, air first passes through air Forecooler reduces the temperature of processing air；Processing air can effectively improve first and remove by the way of being first pre-chilled and dehumidifying afterwards The dehumidifying effect of wet runner, moisture removal under the same conditions, pre- cold energy reduces the regeneration temperature of system, further reduced again Raw energy consumption, and the energy consumption that dehumidifies is almost unchanged, reduces the energy consumption of whole system；Moreover, can reduce the first desiccant wheel again Raw area's temperature of outgoing air reduces the temperature difference of dehumidifying area and renewing zone, further saves the loss of energy.
6, in summer of the invention second air-treatment path and the second air-treatment of winter path, outdoor air passes through board-like Temperature increases behind heat regenerator Secondary Air end, and regeneration temperature needed for the second desiccant wheel renewing zone is constant, main air heater The temperature for needing to heat reduces, and low-grade energy needed for making entire air-conditioning system is reduced, and further reduced energy consumption, to optimize Performance for Air Conditioning Systems.
7, in summer of the invention third air-treatment path and winter third air-treatment path, outdoor air passes through second It is used as the first desiccant wheel renewing zone import wind after the heating dehumidification of desiccant wheel dehumidifying area, the heating of auxiliary air heater, is improved The import air temperature of first desiccant wheel renewing zone, regeneration temperature needed for the first desiccant wheel is constant, auxiliary air heating The temperature that device needs to heat reduces, and low-grade energy needed for making entire air-conditioning system is reduced, and further reduced energy consumption；Reduce by the The water capacity of one desiccant wheel renewing zone air intlet, increases the partial pressure difference of regeneration air Yu desiccant surface vapor, makes It is desorbed more efficient, further increases the regeneration efficiency of the first desiccant wheel.
8, cold needed for cold water needed for dehumidification system and sensible heat air conditioning terminal in summer circulating chilled water path of the invention Source makes underground cold water be not only applicable to rotary wheel dehumidifying side both from underground cold water, moreover it is possible to provide cold source, the two to indoor refrigeration In conjunction with the refrigerating capacity and refrigerating efficiency of the system of raising, sufficient utilization also has been carried out to underground cold water；It not only simplifies entire Air-conditioning system also reduces the equipment cost of the system.
9, in the first air-treatment of winter path of the invention, air first passes through air precooler, reduces processing air Temperature；Processing air can effectively improve the dehumidifying effect of the first desiccant wheel, remove by the way of being first pre-chilled and dehumidifying afterwards Under the same conditions, pre- cold energy reduces the regeneration temperature of system to moisture, further reduced regeneration energy consumption, and dehumidifies energy consumption almost It is constant, reduce the energy consumption of whole system；Moreover, can reduce the renewing zone temperature of outgoing air of the first desiccant wheel, make the area that dehumidifies Reduce with the temperature difference of renewing zone, further saves the loss of energy.
10, the present invention can handle temperature and humidity in air with a small amount of energy consumption, the traditional sky of very good solution Adjusting system is due to the wet Combined Treatment bring energy waste of heat, Temperature and Humidity Control precision is low, moisture removal is small and cold under low temperature environment The problems such as air quality caused by condensate is precipitated is low；This system does not use fluorochlorohydrocarbon class refrigerant, acts on without greenhouse effects； And it can be used with summer in winter, be a kind of technology for meeting modern development requirement, application value is high.
In conclusion novel design of the invention is rationally, at low cost, low energy consumption, and refrigeration and heating efficiency are high, without greenhouse Effect effect, application value are high.
Below by drawings and examples, technical scheme of the present invention will be described in further detail.
