Description
Technical field
The invention belongs to the conditioner field, particularly a kind of small central air conditioning system that has new wind.
Background technology
In China's air-conditioning industry 20 years since being born, be central air-conditioning and the domestic air conditioning general layout of parallel development separately all the time.One of reason is that both market has nothing in common with each other, and the applicable object of central air-conditioning is modern heavy construction, and as hotel, office building, megastore etc., and the user of domestic air conditioning is a family.Yet in recent years, area surpasses 100 square metres dwelling house, the increase of compound apartment and a large amount of exploitations of the commercial house and villa buildings, small central air conditioning system between large-scale central air conditioner system and domestic air conditioning is caused the demand, so " family formula " central air-conditioning market begins comparatively fast to grow up in China.
New wind is the key factor that improves air conditioning comfortableness, and still, traditional air-conditioning system strengthens the increase that resh air requirement means energy consumption.The present invention adopts the mode of full recuperation of heat, reduces the processing energy consumption of new wind; Adopt the humidity that reclaims the new wind of condenser heat extraction the reduction, bear indoor humidity load, thereby improved the efficiency of whole system.Owing to avoided the dehumidification by condensation mode that traditional air-conditioning adopted, air-conditioning of the present invention can not produce moist surface, and this makes air-conditioning system of the present invention become aseptic health-care air-conditioner.
Summary of the invention
The purpose of this invention is to provide a kind of small central air conditioning system that has new wind, it is characterized in that:
Described small central air conditioning system is divided into indoor units and outdoor unit two parts.Indoor units has and is installed in indoor air-treatment end 3, directly regulates indoor temperature, and summer, the refrigeration evaporator temperature was controlled to be 18 ℃, indoor air inlet 4 and the exhaust outlet 5 of also being provided with.The condensation heat extraction end of outdoor unit installation system and independent new blower fan group: condenser 6 is handled terminal 3 with room air and is connected; Solution regenerator 8 is connected with dehumidifier 10 by solution heat exchanger 9; The plate type heat exchanger 11 of dehumidifier 10 is connected with the devaporizer 14 in the indoor wind exit that is contained in the full heat regenerator 12 of solution by water pump 16 and circulating water pipeline; The full heat regenerator 12 of solution regenerator 8, dehumidifier 10 and solution is connected with solution circulation pump 15 respectively; New wind is introduced by air inlet 13, flows through solution full heat regenerator 12 tops and dehumidifier 10 backs by in air inlet 4 inlet chambers, and indoor return air is discharged from exhaust outlet 5, flows through solution full heat regenerator 12 bottoms and devaporizer 14 backs are discharged to outdoor by outdoor exhaust outlet 17.Indoor units and outdoor unit are linked into an integrated entity by the expansion valve 1 and the compressor 2 of air conditioner, constitute compression-type refrigerating system.Air becomes hot-air 7 after condenser 6 heating, hot-air 7 flows through solution regenerator 8, and the moisture of taking away in the solution makes solution concentration raise, the regeneration dehumidification solution.Solution circulates in dehumidifier 10 and solution regenerator 8, and recovers energy by the full heat regenerator 12 of solution.New wind carried out energy exchange by the full heat regenerator 12 of solution with indoor exhaust wind before entering dehumidifier; The new dehumidification process of wind in dehumidifier 10 needs cooling, and cooling water obtains by the evaporative cooling process of air draft in devaporizer 14.
Solution in the described solution regenerator is to have lithium-bromide solution, lithium chloride solution or their mixture that absorbs water in air branch ability, and solution absorbs the moisture in the new wind in dehumidifier, be concentrated regeneration in regenerator.
The invention has the beneficial effects as follows the mode that adopts full recuperation of heat, reduced the processing energy consumption of new wind, overcome traditional air-conditioning system and strengthen the shortcoming that resh air requirement just means that energy consumption increases; And, adopt the heat extraction of recovery condenser to reduce new rheumatism degree, bear indoor humidity load, thereby improved the efficiency of whole system.Simultaneously,, can not produce moist surface, make air-conditioning system of the present invention become aseptic health-care air-conditioner, add new wind and improved air conditioning comfortableness owing to avoided the dehumidification by condensation mode that traditional air-conditioning adopted.
Description of drawings
Fig. 1 is the small central air conditioning system architecture schematic diagram that has new wind.
The specific embodiment
The present invention is a kind of small central air conditioning system that has new wind.
In the small central air conditioning system architecture schematic diagram of new wind shown in Figure 1, described small central air conditioning system is divided into indoor units and outdoor unit two parts.Indoor units has and is installed in indoor air-treatment end 3, directly regulates indoor temperature, and summer, the refrigeration evaporator temperature was controlled to be 18 ℃, indoor air inlet 4 and the exhaust outlet 5 of also being provided with.The condensation heat extraction end of outdoor unit installation system and independent new blower fan group: condenser 6 is handled terminal 3 with room air and is connected; Solution regenerator 8 is connected with dehumidifier 10 by solution heat exchanger 9; The plate type heat exchanger 11 of dehumidifier 10 is connected with the devaporizer 14 in the indoor wind exit that is contained in the full heat regenerator 12 of solution by water pump 16 and circulating water pipeline; The full heat regenerator 12 of solution regenerator 8, dehumidifier 10 and solution is connected with solution circulation pump 15 respectively; New wind is introduced by air inlet 13, flows through solution full heat regenerator 12 tops and dehumidifier 10 backs by in air inlet 4 inlet chambers, and indoor return air is discharged from exhaust outlet 5, flows through solution full heat regenerator 12 bottoms and devaporizer 14 backs are discharged to outdoor by outdoor exhaust outlet 17.Indoor units and outdoor unit are linked into an integrated entity by the expansion valve 1 and the compressor 2 of air conditioner, constitute compression-type refrigerating system.
The air handling process of dedicated outdoor air system is as follows: room air is discharged from exhaust outlet 5, after flowing through the full heat regenerator 12 of solution and pass through evaporative cooling in devaporizer 14, from outdoor exhaust outlet 17 discharge systems.Outdoor new wind carries out energy exchange with indoor return air from air inlet 13 drawing-in systems in the full heat regenerator 12 of solution, pass through dehumidifier 10 afterwards, obtains the new wind that temperature is lower, water capacity is less, sends into indoor from air inlet 4.To discharge latent heat in the dehumidification process, need be cooled, dehumidification solution in plate type heat exchanger 11 with carry out heat exchange from the cooling water of devaporizer 14 and be cooled.The condenser 6 of the refrigeration system of household air conditioning adopts the outdoor air cooling.Outdoor air temperature rising behind condenser is 7 a hot-air, and these hot-airs flow through solution regenerator 8, and the moisture of taking away in the solution makes solution concentration raise, the regeneration dehumidification solution; Solution circulates in dehumidifier 10 and solution regenerator 8, and reclaims cold by the full heat regenerator 12 of solution.
Solution in the described solution regenerator is to have lithium-bromide solution, lithium chloride solution or their mixture that absorbs water in air branch ability, and solution absorbs the moisture in the new wind in dehumidifier, be concentrated regeneration in regenerator.
