Description
Technical field
The present invention relates to field of air conditioning, in particular to a kind of constant humidity perseverance oxygen type gravity total heat recovery antifreeze fresh air
Group and air-conditioning.
Background technology
Digital intelligent fresh air system, recuperation of heat only with sensible heat recuperation of heat mode, can also use runner recuperation of heat,
Plate-fin etc..Heat-pump-type heat recovery solution damping unit freezes to fresh air using heat pump, dehumidifies, heats, humidifying, due to
Heat pump efficiency is substantially in COP3.0 or so, and digital intelligent fresh air system, recuperation of heat is only with ethylene glycol solution sensible heat recuperation of heat
Mode, runner recuperation of heat or board-like recuperation of heat can also be used, runner recuperation of heat have fresh air return air cross contamination,
The mode efficiency of ethylene glycol solution sensible heat recuperation of heat is low and system complex, to design entire water system component, humidification can only be adopted
It is relatively more with high-grade electric humidification method, it does not meet the requirement of energy conservation standard and Green energy-saving buildings or is added using wet film
It is wet, due to humidification amount be difficult be precisely controlled, humidification amount is too small bacterium is easily grown as humidification with spray chamber generates secondary dirt
There are the secondary pollutions such as pipeline corrosion in dye, steam humidification control complexity.So almost all in existing air-conditioning system
Building does not control humidification, unless the building of particular/special requirement.Surface cooler uses copper tube and fin, and weather is less than 0 in winter
DEG C or surface cooler has the danger of bursting by freezing when lower temperature, in north of China weather in 0 DEG C of even -10 DEG C time once
It is very long very universal, so often to close what is stopped using in the coldest weather fresh air in the north, new air-valve is closed, carries out heat preservation
Measure causes fresh air that cannot open, and influences indoor air quality, and carbon dioxide content is exceeded, indoor pollutant for example formaldehyde, VOC,
PM2.5 is exceeded.Also it is exactly to carry out preheating to fresh air using PTC electrical heating to enter back into surface cooler and heat fresh air,
Since electrical heating can not possibly still be wanted emergency cut-off new air-valve in colder weather, stop supply fresh air supply with very greatly,
There is also wastes for electrical heating high-grade energy, do not meet national environmental protection energy saving policy.
