Description
Technical field
It is especially a kind of to take a breath with the fresh air purifying of heat pump and auxiliary electrical heater the present invention relates to a kind of new wind turbine field
Machine.
Background technology
The air-tightness in present room is become better and better, and people are chronically in closed environment, due to lacking necessary air
Circulation, indoor air quality are very poor, it is easy to cause the propagation for not accommodating disease.Therefore, it is necessary to take measures to carry out air friendship
It changes, outdoor fresh air is introduced under conditions of not opening a window, exclude indoor muddy harmful gas.Currently, having opened in the market
Send out ventilation of the new blower fan system for indoor and outdoor.
New wind turbine is a kind of energy-saving air conditioning terminal product, which excludes dirty air out of building, and will
Outdoor ozone (being rich in oxygen) is sent into building.New wind turbine is divided into three kinds at present：The unidirectional air intake of positive pressure, negative pressure are unidirectional
Air-exhaust type, heat pump fresh air, first two is all without heat reclamation device.The third band recuperation of heat, it is two kinds that wherein recuperation of heat, which is divided into,
Mode：Exposure degree and recovery of latent heat, in two kinds of air circulations of fresh air and air draft, unit is in the air conditioner energy (summer in air draft
Ji Lengliang, winter heat) recycling, and be transmitted in fresh air, to reach energy-efficient purpose.
It is very unhygienic although outdoor fresh air is rich in oxygen but recently as the getting worse of atmospheric haze,
Especially PM2.5 particle concentrations are high, while there is also the harmful microorganisms such as many viruses, bacterium, also sulfide, nitride
It is sent into meeting in building room with these inorganic pollution gases, such fresh airs such as ozone and cause very big shadow to people's health
It rings.
If new wind turbine does not have the ability for filtering these dust particles, harmful microorganism and inorganic pollution, newly
The entrance of wind may be decreased the quality of room air instead.And in winter or summer, the air themperature psychrometric difference of indoor and outdoor
It is not larger, if new wind turbine cannot effectively recover energy, the burden of room conditioning will be increased, not only comfort is poor, does not also save
Energy.
Currently, many new wind turbine bands heat recovering heat exchanger, but the following some problems of generally existing：Heat recovery efficiency first
Low, total heat recovery efficiency is generally below 60%, and summer effect on moisture extraction is poor, and winter inlet air temperature is low, reduces comfort, causes simultaneously
The waste of energy increases the energy consumption of room conditioning；Secondly leakage is serious in heat recovering heat exchanger, and indoor pollution air leaks into newly
In wind, fresh air is polluted, reduces the air quality of air inlet；Third heat recovering heat exchanger surface moisture is mouldy, grows bacterium, makes
At secondary pollution；4th, heat recovering heat exchanger windage is generally bigger than normal, is generally not less than 100pa；Finally, total heat recovery heat exchanger
Service life is not grown generally, in long-term moist adverse circumstances, will replace within general 1 year, use cost is high.
