Description
Technical field
The invention belongs to technical field of air-conditioning heat pumps, particularly to a kind of wind pipe type CO2Air conditioner and heat pump unit.
Background technology
Airduct unit is will to be connected with copper pipe between an off-premises station and an indoor set, the cold wind produced from indoor set
(warm braw) is drawn ajutage and is led to each room, then sends indoor set back to through backwind tube, and cooled (heating) mixing portion are new
Send again after wind, be the central air-conditioning of a kind of brand-new air system.Energy-saving effect is obvious, and air pipe air conditioner source pump belongs to direct-cooled
Formula system, evaporating temperature is higher, in the case of other conditions are certain, improve evaporating temperature and can improve efficiency and the energy of unit
Effect ratio.Wind pipe type unit air-conditioner unit capacity is bigger, it is possible to meet refrigeration (hot) requirement in many rooms, family, supplements new wind the most square
Just, the layout sending air port back to can need to carry out flexibly according to finishing, being evenly distributed of indoor cold-hot wind, air ambient comfort level
Higher.The use of the supply air system of wind pipe type unit air-conditioner unit is extremely widespread in the U.S., be suitable for the tall and big spaciousness in U.S. room,
Extensive individual demand.In recent years, this kind air conditioning unit also had not in some economically developed big city such as Beijing, Shanghai etc.
Few use example, the particularly villa buildings of some top grades.But it is bigger that its shortcoming is mainly noise, it is sometimes desirable to consider noise reduction
Measure.System is installed more complicated, sends the layout of airduct back to and should take certain interior space, and indoor are hung item and matched therewith again
Closing, indoor set is also required to take certain careat or space is placed, and is less suitable for the national conditions of China.Each room send
Return air, while improving indoor environment comfort level, also brings indoor, each room epidemic disaster and is difficult to the problem of regulation, the most also
Can use motorized adjustment air-valve, this another aspect adds system cost, additionally too increases the difficulty of system fading margin and control
Degree and complexity, be to spend and don't just for family uses after all.
Wind pipe type unit air-conditioner unit mainly has two kinds of typical mounting means: Yi Zhongfang according to its difference heating mode
Formula is to use air-cooled heat pump type Split cabinet type air conditioning unit, and indoor cabinet assists to inject formula heater, it is possible to provide 5kw-
The electric heating increment of 20kw, realizes the conversion of summer in winter operating mode by the commutation of cross valve；Another kind of typical mounting means is room
Interior machine combines into high efficiency burnt gas heating furnace, system humidifier and electronic filter, and off-premises station is then air-cooled single cold type, with Summer and winter
The conversion of joint realizes cooling or heat supply.Electronic filter is arranged on return air house steward, and humidifier is installed on header pipe, uses
To add in wind pushing air when heat supply mode water vapour, improve the humidity of room air.
Traditional air-duct-type air-conditioner source pump, is used mostly the tradition working medium such as R22, R134a, and the feature of environmental protection is poor, faces
The trend being gradually eliminated.System, when running dehumidification mode, needs to open assisted heating device, carries out the air after dehumidifying
Heating, to reach comfortable temperature.On the one hand such assisted heating device makes system become complicated, adds equipment cost,
On the other hand, improve energy consumption when system is run, make system heating efficiency reduce.It addition, traditional air-duct-type air-conditioner heat pump
Unit operating pressure is relatively low, and the energy-saving effect using ejector is inconspicuous, and substantial amounts of expansion work is wasted, and systematic function is relatively low.
