Technical field
The present invention relates to a kind of low-temp recovery and grab wheel dehumidification system and method, belong to filed of air conditioning.
Background technology
The problem that often needs to solve dehumidifying in industrial production and people's daily life, the humidity of air directly affects people's production and life.Along with growth in the living standard, people require also constantly to promote to the quality of life, research shows, under hot environment, the higher hotness that can increase human body of air humidity, but under low temperature environment, too high humidity can make the thermal resistance of clothing reduce, strengthen the heat transfer of human body and clothing, can increase on the contrary the creeping chill of human body.So too high humiture is felt like a hen on a hot girdle people.People also put forward higher requirement to the control of humiture; On the other hand, as the wall in basement warehouse, if humidity too high will be taken care of article make moist, mouldy; Some switchgear houses, if humidity is too high, high-tension circuit refluxes the danger of leak source can occur.This can produce greatly and destroy industrial production etc.
The humidity of air is processed existing a variety of methods, such as freeze drying, liquid dehumidifying, rotary wheel dehumidifying etc.Rotary wheel dehumidifying is because its simple structure, runner long service life, moisture absorption area are large, can obtain continuously low dew point, the dry air of low temperature, there is no the feature such as spittle loss of liquid-absorbant and is used widely.But dehumidification system for runner regeneration needs higher temperature, to having relatively high expectations of the energy.In recent years the patent of China's rotary dehumidifier is more, but the required thermal source of regenerating is not solved completely.The rotary dehumidifier relating to as ZL200810029440.4 forms complicated; The ultrasonic wave dehydrating unit that ZL200710173274.7 proposes is relatively difficult to realize; Other a lot of dehydrating unit energy consumption aspects have more loss especially.For easy and simple to handle, simple in structure, the obvious rotary wheel dehumidifying air-conditioning of energy-saving effect demand is urgent.
Summary of the invention
The object of this invention is to provide that a kind of dehumidification rate is high, the obvious low-temp recovery dehumidification system for runner of energy-saving effect.
A kind of low-temp recovery runner system, is characterized in that: be made up of low temperature dehumidification system for runner and thermal regeneration system; Wherein low temperature dehumidification system for runner comprises the filter, one-level evaporimeter, the secondary evaporimeter that are connected successively with outdoor new wind entrance; Also comprise desiccant wheel, the dehumidifying section entrance of desiccant wheel is connected with secondary evaporimeter outlet; Also comprise the auxiliary heater, the pressure fan that are connected successively with the outlet of dehumidifying section, pressure fan exports with indoor identical; Wherein thermal regeneration system comprise be connected in successively between indoor fresh air entrance and desiccant wheel regenerator section entrance regeneration filter, secondary condenser, regeneration auxiliary heater; Also comprise with regenerator section and export the regeneration blower fan being connected, regeneration fan outlet communicates with outdoor.
The method of work of described low-temp recovery runner system, is characterized in that comprising following process:
Summer condition: the low temperature dehumidification system for runner in low-temp recovery runner system: pressure fan is by the air intake low-temp recovery dehumidification system for runner of summer high temperature high humidity; Through the hot and humid air stream of filter, after one-level evaporimeter, temperature reduces; By secondary evaporimeter, the temperature of air is further reduced again; Now the air of low temperature and high relative humidity is again after desiccant wheel dehumidifying section, and humidity reduces, and temperature slightly promotes; The air of low temperature and low humidity enters indoor after auxiliary heater heating again by blower fan.Thermal regeneration system in low-temp recovery runner system: under the drive of regeneration blower fan, the indoor low temperature gas of the regeneration filter of flowing through is by secondary condenser, and temperature improves; Then further improve through the air themperature of regeneration auxiliary heater; Now the air of high temperature low humidity, by desiccant wheel regenerator section, makes the regeneration of desiccant wheel dehumidifying effect; Then air is sent outdoor through regeneration blower fan; Wherein desiccant wheel keeps rotating according to certain speed, and then dehumidifying section and the regenerator section of runner ceaselessly changes, and has realized the sustainable use of runner;
Winter condition: due to temperature and humidity all on the low side, native system is one-level evaporimeter secondary evaporimeter, desiccant wheel, regeneration blower fan, regeneration auxiliary heater and secondary condenser are all adjusted to closed condition to adapt to winter conditions.Pressure fan is in the air intake system of outdoor low temperature and low humidity, through the air of the low temperature and low humidity of filter, after heating by auxiliary heater enter by blower fan indoor;
Conditioning in Transition Season operating mode: conditioning in Transition Season operating mode: because temperature is not high, native system is adjusted to closed condition to adapt to conditioning in Transition Season condition by one-level evaporimeter and regeneration auxiliary heater.
With respect to conventional rotor dehumidifier, this low-temp recovery dehumidification system for runner combines dehumidification system for runner and compression-type refrigeration circulation, evaporimeter in compression-type refrigerating system and refrigerator are respectively runner the cold of the front precooling of dehumidifying and the heat of regeneration heating are provided, effectively utilized low-temperature heat source, energy-saving effect is obvious.
