Background technique

Today's society, with the rapid development of Chinese society economy, improvement of living standard, people are to indoor living environment It is required that also higher and higher.Air quality largely affects people's lives quality in residential building.Temperature and humidity As the performance indicator of air-conditioning, it is an important factor for influencing indoor air quality, while in order to ensure Interior Space makings in building Amount just must be introduced into outdoor fresh air, and a set of Fresh air handling units for capableing of conditioning, which become, improves the important of indoor air quality Mode.

Conditioning can be carried out to air using the airhandling equipment of solution humidifying technology, utilize dehumidification solution physics Chemical characteristic can carry out sterilization dedusting to air, and while guaranteeing to blow quality, solution humidifying technology is excellent in terms of energy conservation Gesture also obtains the approval of society.

Air-conditioning is to separate with Fresh air handling units in the prior art, is taken up a large area；Current air-conditioning be divided into domestic air conditioning and Central air-conditioning, domestic air conditioning do not have fresh air system, such as common split air conditioner, such as want to be needed to install individually new blower with fresh air, Central air-conditioning generally has independent fresh air system, and split-type air conditioner is temperature and humidity coupling processing, and energy consumption is high, no fresh air, central hollow Adjusting is also temperature and humidity coupling processing, needs independent fresh air system, volume is excessive, and pump type heat solution humidifying in the prior art is new Blower fan group there are cold and hot flux matched unevenness, when the cooling capacity that the evaporator in heat pump system provides reaches service requirement, condensation The heat exhaust of device is often excessive, causes the imbalance of system capacity.In addition, the solution dehumidification pipeline in system, there is also salt The problem of solution corrosion unit, causes salting liquid to leak since valve is excessive on pipeline, leads to the phenomenon that corrosion unit hair occur It is raw.

Chinese invention patent, publication number: publication date: 105526655A on April 27th, 2016, it is molten to disclose a kind of heat pump The new blower of liquid is related to blower technical field, including weak solution slot, concentrated solution slot, infiltration plate, dense saline solution, dilute salting liquid, process Pump, condenser, technique blower, regeneration pump, evaporator and regeneration blower, the setting of infiltration plate concentrated solution slot and weak solution slot it Between；Process pump is arranged on weak solution slot, and condenser is arranged in the air inlet on the inside of weak solution slot and is located at dilute salting liquid One end of top, condenser is connect by pipeline with process pump and the other end of pipeline extend to weak solution slot upside outlet air At mouthful, technique blower is arranged on the upside of weak solution slot and is located at air inlet；The air inlet on the inside of concentrated solution slot is arranged in evaporator Top at mouthful and positioned at dense saline solution, one end of evaporator is connect by pipeline with regeneration pump and the other end of pipeline extends to At the air outlet of the upside of concentrated solution slot.The invention simple installation, easy to use, occupied area is small, and production cost is low, energy-saving ring It protects, it is high-efficient.Disadvantage is that: the invention is arranged between concentrated solution slot and weak solution slot by infiltration plate, reduces The probability of salting liquid leakage corrosion, but there are the unbalanced problems of unit concentration for the invention, and can not achieve accurate control.

Chinese invention patent, publication number: publication date: 104075393A on October 1st, 2014, discloses a kind of solution tune Damp and hot pump type Fresh air handling units, including solution recycle system and cold and hot matchmaker's circulatory system, cold and hot matchmaker's circulatory system includes compressor, pressure Contracting machine heating agent end connects expansion valve one end by three equipment in parallel, and the expansion valve other end three equipment connect compressors in parallel are another One end, the solution recycle system include the pretreatment internal heat type solution regeneration system and pretreatment inner-cooled solution dehumidification System, the pretreatment internal heat type solution regeneration system upper end is by pipeline and pre-processes inner-cooled solution dehumidification system lower end Weak solution slot is connected, and the pretreatment inner-cooled solution dehumidification system upper end passes through another pipeline and pretreatment internal heat type solution The concentrated solution slot of regenerative system lower end is connected, the present invention have the advantages that it is small in size, structurally reasonable, energy consumption can be effectively reduced. Disadvantage is that: the parallel connection of the invention is that the heat or cooling capacity in heat pump are divided into three parts successively by way of in parallel It is transmitted to air, such as dehumidification process, what is utilized is the cooling capacity of heat pump system, which passes through air cooling heat exchanger for a part of cooling capacity Outdoor air is pre-chilled in dehumidifier, part energy is by the cooling salting liquid of the second pipe heat exchanger, then passes through salt The spray of solution passes to air, some heat carries out cooling processing to not up to treatment temperature air after processing again； Although the system condensation side has an external air-cooled condenser, need to shut down but if liquid level is excessively high in solution pool, the invention is molten Liquid pool design uses original cuboid design, and solution storage amount is limited, while Fan Regulation thermal balance is limited, needs to shut down； In addition, the external condenser of the invention can only make condenser summer, winter is not acted on, which does not introduce winter humidification work Condition needs another heat exchanger to make condenser, and equipment is more, increases cost.

Chinese invention patent, publication number: 104456798A, publication date: on March 25th, 2015, disclosure of the invention one kind Realize the heat pump driving solution humidifying and domestic hot-water's preparation system of energy balance.It is characterized by: the system comprises heat pumps The circulatory system, solution humidifying system；The heat pump system includes frequency-changeable compressor, four-way reversing valve, the cooling condenser of solution, stops Valve, throttle valve and evaporator are returned, water-cooled condenser is also introduced and carries out producing for domestic hot-water；The solution humidifying system contains Dehumidifier, regenerator, solution pump, solution heat exchanger, solvent valve and blower；The invention is by solution recycle system, heat pump system Combine with domestic water preparation system, while heat pump drives and realizes solution humidifying, utilizes the extra condensation of refrigerant Heat produces domestic water, has reached the effective use of system capacity balance and the energy, has improved systematic entirety energy.Shortcoming The phenomenon that being, the solution exchanged form or traditional approach of the patent, salting liquid is easily caused to corrode, energy consumption is high, efficiency It than reducing, is only capable of hot water heating in actual tests to 20 degree, if thinking the purpose of realization heat hot water, system bulk need to be increased, Corresponding energy consumption will will increase, and reduce the efficiency of system, higher cost more using equipment.
