Embodiment
Describe the full thermal purification VMC that the utility model is provided in detail below in conjunction with the accompanying drawings, as shown in figure 1, including The new blower fan and sensible heat air conditioner being connected with each other.Wherein, the fresh inlet of new blower fan leads to outdoor, by outdoor acquisition fresh air, newly The fresh air outlet of blower fan is connected to the fresh air air inlet of sensible heat air conditioner.The fresh air air outlet of sensible heat air conditioner leads to interior, carries Waste air in cooling/heat, the waste air return air inlet recovery room of sensible heat air conditioner, the waste air air outlet of sensible heat air conditioner is divided into two Road, is exported to the waste air import of new blower fan all the way, and another road is exported to the fresh air air inlet of sensible heat air conditioner.The dirt of new blower fan Wind outlet is arranged to outdoor by waste air.
Existing air conditioner load can be divided into two classes, including people's type load and (building) species load.
Wherein, people's type load is the load produced by human survival, such as new wind load, human-body radiating (full heat).It is this kind of Load is given birth to because of people, and nobody is just without this type load, and its size is relevant with number and human survival quality, and (air quality will Ask higher, load is bigger).In general, aggregation is built, and such as classroom, meeting room, dining room, arenas, people's type load accounting is very It is high.People's type load has following feature:The load of people contains whole humidity loads, for example human breathing and produced by perspiring Moisture.And the load of people is " instantaneity ", people is then having, people walk then without.
(building) species load is " building enclosure load ", belongs to the load produced because of building heat transfer or using equipment, with Human survival is unrelated, and the size and building heat preservation and purposes of this type load are closely related.Species load has following features:Thing Load does not include humidity load, and with certain time-delay characteristic, due to the hot gap of wall, outdoor heat (sun, temperature) is passed to Interior is usually required after 4~12 Small Time Lags, and such as lag time is the load of the building of 8 hours, and the highest temperature is 14:00 Occur, due to time-delay characteristics, thermic load peak appears in 22:00, and now outside air temperature has escaped the high temperature period.
The effective ways of reduction species load are reinforcement building heat preservation and use energy-conserving device.The measure of this respect and will Ask and embodied in relevant specification of country, effect is realized very well, by taking Beijing as an example:Heat transfer across wall load is from previous generation Record last average about 80~120W/m2, it is reduced to 50~70W/m2, some energy saving buildings are even up to 20~30W/m2
Corresponding with species load, people's type load requires the reasons such as raising due to Indoor Air Pollution with outdoor Air Pollution, life quality, It is increasingly becoming the principal contradiction of air conditioner load;With 30m per capita3Exemplified by/h fresh airs, in the Yangtze river basin and areas to the south, outdoor is pressed 35 DEG C, relative humidity 70%, interior presses 25 DEG C, and relative humidity 55%, species load (load containing building enclosure) is smaller, the mankind Accounting of the load in air conditioner load is relatively large.Now, being made an effort in species load has lost more than gain, and reduces building energy consumption Emphasis need to people's type load processing on have in mind, can get twice the result with half the effort.
Based on above-mentioned theory, the application separately handles the load to people and the load to thing, and people is handled by new blower fan Load, new blower fan is using fresh air as carrier, extracting energy (cold/heat/moisture content) to return air/air draft, so as to pass through heat Wet process makes the indoor air underwriter's type load in full of feeding.Further, it can be supplied in real time newly by cleaning equipment Fresh, pure air.After above-mentioned processing so that the load of sensible heat air conditioner only processed material, it can be greatly reduced in theory The energy consumption of existing sensible heat air conditioner.
