Description
Technical field
The present invention relates to air-conditioning technical, is a kind of air conditioner, belongs to the air conditioner technical field of machinery product.
Background technology
Temperature and humidity is essential two parameters controlling of air-conditioning process.Conventional domestic or business air conditioner are mainly temperature difference air-conditionings, often only focus on temperature adjustment, do not focus on damping, and then cause a series of air hygiene problem, and serious waste energy problem.
Human body is exactly comfortableness to the sensitiveness of temperature and humidity, when relative air humidity is lower than 40% time, easily causes respiratory disease; When relative air humidity is higher than 60% time, the vigor of the nuisances such as dust-full, bacterium, virus, fungi starts to strengthen.Many comfortablenesses experimental results show that: different ethnic groups have different humiture comfortableness intervals, the human body temperature that Chinese are desirable and humidity environment are 23～28 DEG C of temperature, relative humidity humidity 45～65%, under the prerequisite that meets human body comfort, dry-bulb temperature is more high more energy-conservation.When dry-bulb temperature raises, comfortableness requires relative humidity to answer corresponding adjusting.
Air-conditioning total load comprises sensible heat load and latent heat load binomial content, and latent heat load mainly refers to humidity, before ensureing comfortableness, puts and effectively controls this binomial content, can significantly save unnecessary energy consumption.The ratio of air-conditioning total heat duties and latent heat load claims there is significant difference in different regions by heat moisture ratio, and in areal, different period Various Seasonal difference are also very large, also has difference in areal with the period when different dry bulb temperature.In addition, along with the continuous application of modern construction engineering energy-saving material, heat moisture ratio is also change (heat moisture ratio diminishes), and the proportion of latent heat load in total load is increasing, and controls the importance of latent heat load by outstanding day by day.In recent years, country had issued 26 DEG C of air-conditioning policies in summer, and because existing standardization air-conditioning is in the time that air dry-bulb temperature is greater than 26 DEG C, air humidity is higher or fluctuating range is larger, easily makes people feel uncomfortable, and the practicable execution of 26 DEG C of air-conditioning policies is not ideal.If air conditioner effectively adjusted in concert temperature and humidity is that humiture is independently controlled, 26 DEG C of air-conditioning policies will be subject to more majority's welcome, have data to show, humiture independence control technology can realize 20～40% the energy saving space.
Present stage, humiture independence control technology was in salting liquid damping mode as main, salting liquid meeting corroding metal, dehumidification process inevitably has elegant spittle particle, being less than 0.3 μ m salting liquid particle can be taken away by air, someone queries always in its security, particularly it also brings comparatively complicated engineering design with Gao Ang invests, and humiture independence control air conditioner system Difficulty is heavy.How to simplify and improve damping equipment and reduce the key that engineering cost is exactly the popularization of humiture independence control technology.Main target of the present invention is just to provide a kind of low cost and humiture safe and reliable to operation, easy maintenance is independently controlled air-conditioning equipment, be convenient to build or built engineering in promote the extensive use of humiture independence control technology.
Summary of the invention
Independent humiture-controlled air conditioner, be a kind of can adjusted in concert air themperature and the air-conditioning equipment of humidity, independently control air-conditioning with existing solution-type humiture compared with, its integrated cost is lower, safety, easy maintenance; Compared with current known air conditioner, its comfort conditioning space is larger.This equipment contributes to implementing of 26 DEG C of summer air-conditioning policies of country.

Detailed description of the invention
In humid air theory, there is a principle: damping can cadre enrolled among workers's bulb temperature, and cadre enrolled among workers's bulb temperature is wayward humidity.This principle is also a theoretical foundation of the present invention.Preferential controlled humidity target, Synchronization Control dry-bulb temperature, just can realize Temperature and Humidity Control general objective.
A) indoor set:
As shown in Figure 1, main contents: 1 blower fan, 2 surface coolers (air cooled heat exchanger), 3 sensible heat ventilation cores (air-air Recuperative heat exchanger), 4 refrigerants, 5 Temperature and Humidity Control mechanisms.
Indoor set workflow: pending air enters return air channel, enters 3 sensible heat ventilation cores, and return air air obtains precooling, dry-bulb temperature declines to some extent, relative humidity significantly improves, then it is further cooling to enter 2 surface coolers, and wet and dry bulb temperature further declines and forms low temperature and low humidity air.Because the part sensible heat of air is removed in 3 sensible heat ventilation cores, the in the situation that of equal cold and the contrast of traditional air conditioner, the latent heat of air can be removed more.Low temperature and low humidity air is sent into 3 sensible heats ventilation cores after being aspirated by 1 blower fan.Low temperature and low humidity air carries out heat exchange with pending return air air in 3 sensible heat ventilation cores, dry-bulb temperature raises, relative humidity significantly reduces (water capacity is constant), forms wind pushing air, and the condensate water on 2 surface cooler walls is flowed out by chassis discharge outlet simultaneously.The cold of 2 surface coolers is provided by 4 coolant medias, and refrigerant can be cold-producing medium (as: fluorine chlorine is held high or alternative chlorofluoro carbon) or liquid coolant (as: frozen water), and 1 blower fan also can be located on the position, air channel of air outlet or return air inlet.
Indoor set can be separately as a product, and the motorized adjustment that the import or export of 2 surface coolers that now should be in Fig. 1 installs adjustable 4 cold medium fluxes additional is cut down, and can be used as fan coil or variable air volume air conditioner in known central air-conditioning.
B) off-premises station:
As 6 in Fig. 2, off-premises station can be the off-premises station of the known separating air conditioner with adjustable speed compressor, can be also the frozen water unit with adjustable refrigerating capacity.The cold that off-premises station is produced offers indoor set by coolant media.
Basic demand is: off-premises station has the mechanism that realizes of adjustable refrigerating capacity.
C) Temperature and Humidity Control mechanism and control method:
As shown in Figure 2,5 Temperature and Humidity Control mechanisms are made up of known sensor, controller and actuator, and its function is to regulate the refrigerating capacity of 6 off-premises stations and the rotating speed of 1 blower fan according to the requirement of air-conditioning object.The refrigerating capacity of 6 off-premises stations is regulated by the rotating speed of the refrigeration compressor in 6 off-premises stations, the rotating speed positive correlation of the refrigerating capacity of 6 off-premises stations and compressor.The rotational speed regulation indoor set circulated air flow of 1 blower fan.The refrigerating capacity of 6 off-premises stations can be controlled the humidity and temperature of processing air, and the rotating speed of 1 blower fan also can be assisted the humidity and temperature of controlling air, realizes the Temperature and Humidity Control of air.In addition, the rotating speed of 1 blower fan can change the heat exchange efficiency (air mass flow is larger, and the heat exchange efficiency of sensible heat ventilation core is lower, and supply air temperature difference is larger) of sensible heat ventilation core, and indirect regulation supply air temperature difference, reaches the object that regulates indoor temperature.
