Description
Technical field
The utility model relates to the advancing of central air-conditioning, exhaust duct unit.
Background technology
Now, central air conditioner system in the market, hospital, office building, hotel extensive use.But central air-conditioning power consumption is bigger on the one hand, and significant proportion is a new wind load in the load of central air-conditioning, and common 10% resh air requirement accounts for total load and reaches 20%.On the other hand, people are to the raising of life, comfortable working environment requirement, and are also more and more higher to the requirement of central air conditioner fresh air amount, the particularly outburst of SARS in 2003 and popular, people more pay close attention to resh air requirement, about just clearly proposing resh air requirement will reach 30m in the operating specification of central air-conditioning
3/ h. people makes general central air conditioner system resh air requirement bring up to more than 20% from 10%, and this is the concern to health of people.But the raising of resh air requirement directly causes a large amount of losses of energy, and resh air requirement reaches 20%, and its new wind load will reach 40% of total load.Therefore must seek effective energy saving technology, to alleviate the power tense situation of bringing owing to air conditioning applications.
Processing method for the central air-conditioning new wind load has two kinds of schemes usually at present: one, use brand-new blower fan group and handle new wind load, it is the new wind air-cooled ducted air conditioner of the direct vaporation-type of working medium with freon that this unit has application, has also that to answer water be the common air-conditioning punch-out equipment group of media.Though the efficient of the processing mode unit of this new wind is higher,, thereby generally speaking be not energy-conservation because lot of energy is discharged in the atmosphere.The second way is that the energy that application recuperation of heat unit will be discharged in the atmosphere reclaims, and irretrievable part solves with the way that increases the central air-conditioning ability.This way is a kind of power save mode owing to reclaimed lot of energy in the system.But, still there is the waste of energy because unit unit efficiency under the application operating mode is not high.
Summary of the invention:
The problem that the utility model need solve provides a kind of energy-conservation heat recovery type full fresh airduct road unit.
The technical solution of the utility model adopts box-shaped insulation framework, airduct, blower fan, full heat converter core and comprises heat exchange coil, compressor, four-way change-over valve, filter, expansion valve, is connected refrigeration or operation of heat pump system that copper pipe is formed, it is characterized in that being provided with air intake passage, air-out passage, full heat converter core in the box-shaped insulation framework of unit, air-supply side dress heat exchange coil and pressure fan in the air intake passage, air draft side dress heat exchange coil and exhaust blower in the air-out passage; Four sides of full heat converter core are respectively a, b, four cavitys of c, d; Exhaust duct is docile and obedient preface and is communicated with b cavity, full heat converter core, d cavity, air draft side heat exchange coil, exhaust blower; Blast pipe is docile and obedient preface and is communicated with a cavity, full heat converter core, c cavity, inlet side heat exchange coil, pressure fan.
The utility model is owing to combine recuperation of heat with new wind air-cooled ducted air conditioner, energy in the combustion gas (cold or heat) is through total-heat exchanger, heat exchange coil reclaims for 2 times, the energy that reclaims is passed to new wind, not only have full recuperation of heat unit and new wind air-cooled ducted air conditioner unit dual-use function, satisfy central air-conditioning to new wind and requirements of saving energy, and it is more energy-conservation more than 40% than common brand-new wind air-cooled ducted air conditioner, unit moves more stable than common brand-new blower fan group in summer under maximum temperature and the winter minimum temperature operating mode, fault rate is low, working service is convenient, can be widely used in various central air conditioner systems, the VRV multi-online air-conditioning system.
