Description
Technical field
The utility model relates to a kind of fresh air conditioner system device, especially relates to a kind of energy recycle device of fresh air conditioner system.
Background technology
Current, along with Global Greenhouse Effect is more and more serious, energy-saving and emission-reduction are paid attention in the whole world all utmost point.According to relevant statistics, have 30% to be directly used in human building of being lived in whole society's total energy consumption approximately, and have 50% to be used for heating and air-conditioning system in the building energy consumption approximately, human for primary demand healthy and comfort level, per hour generally need 30m
3The resh air requirement that/h is above, new wind of outdoor high temperature in summer or the new wind of outdoor low temperature in winter will consume lot of energy and just can be cooled to or be heated to the needed comfort zone in room.
In the energy that air conditioner heating system consumed, new wind load accounts for about 30%.Now the new building building enclosure has been taked strict measures such as energy-saving heat preserving, new wind load even might be up to 50%.The variation of resh air requirement has very big influence to the load of air conditioner heating system.Therefore, satisfying under the situation of code requirement, reducing the air conditioner fresh air load is energy-conservation important measures of heating ventilation air-conditioning system.All must there be VMC in any central outage system, though present most of residential architecture dress all is split-type air conditioner, no VMC, but for healthy a lot of common people have the custom of windowing and turning on the aircondition, the therefore new shared energy consumption of wind also will have about 30%.There is new wind that air draft is just arranged, it is a kind of significant wastage of the energy that the indoor dirty air that is cooled or heats is discharged outdoor, if utilizing effectively, device recovery section energy from the energy (heat, cold) that air draft is taken away is used for handling new wind, can save the new wind load of bearing by refrigeration or heating machine set originally, improve the efficient of air-conditioning system.
In recent years, increasing manufacturer all participates in and the cold and hot amount recovery of production air draft unit.The interchanger that is used for exhaust air energy recovery now is mainly total-heat exchanger and sensible heat exchanger two, and adopt the main distinction of total-heat exchanger and sensible heat exchanger only to be: less at indoor/outdoor temperature-difference, and the bigger zone of temperature difference, total-heat exchanger mainly is higher than sensible heat exchanger in the summer in organic efficiency, heat recovery efficiency in winter is relevant little, so the scope of application of total-heat exchanger is more extensive than the scope of application of sensible heat exchanger.
It is the board-like heat exchanger of base material that the domestic and international present full heat exchange unit that is used for exhaust air energy recovery generally adopts with special paper, and the mode of cross-current is adopted in new wind and air draft, and sensible heat carries out heat exchange by paper, and general heat transfer coefficient is less than 30W/m
2K, the latent heat steam partial pressure difference by new air draft side realizes by the little pore mass transfer of paper when therefore freezing only there being about 50% full heat exchanger effectiveness, and also has polluter in the air draft or the virus infiltration risk in the new wind.And traditional sensible heat exchanger generally adopts metal to make base material, adopts the mode of rectangular cross flow, and temperature exchange efficient is higher, avoided the possibility of cross pollution, but it can not carry out latent heat and reclaims, and therefore the organic efficiency when the temperature high temperature difference freezes little regional summer is lower, generally is lower than 50%.
In field of heating ventilation air conditioning, ventilation and energy-recuperation system are widely used in dwelling house and the public building, relate to multi-functionals such as new wind, air draft, return air, energy recovery, traditional form is that new wind is handled by new blower fan group, and air draft is by the air draft unit, and energy reclaims establishes refill, aluminium core or runner heat regenerator, but above-mentionedly there is a following drawback: first, new wind, exhaust equipment partial installation volume are big, take machine room than large tracts of land, the installation and maintenance complexity; The second, the energy recovery is the highest can only to reach 40%, and organic efficiency is low; The 3rd, the unsuitable maintenance clean of energy recycle device, decay is fast, the effect that basic noenergy reclaims after 2 years; The 4th, energy recycle device needs new, air draft cross-exchange, causes degradation problem under taint of odour, the air quality.Therefore, design a kind of fresh air treatment system efficiently and become the technical barrier that those skilled in the art press for solution.
Summary of the invention
The technical problems to be solved in the utility model provides that a kind of air is clear, the energy recycle device of energy-conserving and environment-protective, fresh air conditioner system that energy recovery rate is high.
The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of energy recycle device of fresh air conditioner system, comprise exhaust system and VMC, described exhaust system comprises the exhaust-air filter that is fixedly connected sequentially, condenser, gas-liquid separator and air draft centrifugal blower, described VMC comprises the new wind roughing efficiency air filter that is fixedly connected sequentially, new wind medium effeciency filter, evaporimeter, gas-liquid separator and new wind centrifugal blower, it is characterized in that, also comprise energy-recuperation system, described energy-recuperation system comprises compressor, the cross valve and first heating power expansion valve, three end delivery outlets of described cross valve respectively with described evaporimeter, gas-liquid separator is fixedlyed connected with condenser, fixedly connected with the delivery outlet of described compressor in the input port of described cross valve, first input port of compressor is connected with the delivery outlet of described gas-liquid separator, second delivery outlet of compressor, the delivery outlet of cross valve, the input and output mouth of evaporimeter and the input and output mouth of condenser are fixedlyed connected with first heating power expansion valve respectively.
