Abstract
A novel fresh air exchanging device consists of shell, fan and heat exchanger. The shell is disposed with two fans with outward tuyere at upper part, a fork flow type static and plate heat exchanger at center, a contaminated wind outlet at upper left part, a fresh air inlet at lower left part, a fresh air outlet at upper right part, and a contaminated wind inlet at lower right part. The fresh air exchanging device can exchange equivalent indoor and outdoor air, which can not influence cold and heat load, largely reduces the energy needed by fresh air processing and accomplishes high efficiency energy-saving; fresh air is filtered by filter of machine set, which effectively prevents dust and harmful substance into room, keeps air to be fresh; the machine set reduces cold-heat processing device, reduces to a large extent the operation cost, accomplishes union of environment protection and high efficiency energy-saving.
Description
Technical field: the utility model relates to ventilator, particularly relates to a kind of fresh air-changing device.
Technical background: for satisfying modern architecture comfortableness and the more and more higher requirement in artistry two aspects, modern architecture has generally been introduced air-conditioning system.Because often the side effect of using new wind deficiency of air-conditioning system or improper ventilation can cause indoor air quality badly to bring is more and more obvious; The pernicious gas of indoor generation and biological pollution can not get dilution rationally and displacement, CO
2Content raises, and various symptoms of respiratory disease occur.Healthy, energy-conservation, simple and direct, reliable VMC and equipment become the problem that building, Air-conditioner design and user generally are concerned about the sixth of the twelve Earthly Branches.
Summary of the invention: the purpose of this utility model will provide a kind of fresh air-changing device exactly, and it can overcome assembling air-conditioning system and the existing problem of room air well.The purpose of this utility model is achieved in that a kind of fresh air-changing device is made up of housing, blower fan, heat exchanger, it is characterized in that: be respectively arranged with two blower fans above in housing, the air port of two blower fans respectively outwards; Central authorities at housing are provided with static, the flat plate heat exchanger of cross flow; Be provided with dirty wind outlet on the housing upper left side, the lower left is provided with fresh inlet, and the upper right side is provided with new wind outlet, and the lower right is provided with dirty wind inlet.The displacement of the utility model indoor and outdoor gas equivalent; The static heat exchanger that is provided with, energy recovery rate reaches more than 70%, and indoor cooling and heating load is not subjected to new wind effect, reduces new wind significantly and handles institute's energy requirement, realizes energy-efficient; Air in the inlet chamber filters through filter in unit, effectively prevents in dust and the harmful substance inlet chamber, keeps room air fresh; Set low noise outer rotor centrifugal blower, the unit wall is coated with novel sound-absorbing material, and the noise that operates steadily is low, has prevented the interference to the scene; Complete machine is movement-less part except that blower fan, and almost Maintenance free can be guaranteed reliably working steady in a long-term; Substitute new wind treatment facility, needn't set up machine room, can reduce equipment investment and construction area and utilize the heat recovery technology operating cost of saving energy and reduce the cost, save new wind and handle energy consumption more than 30%, no Cooling and Heat Source supply, integral structure reduces maintenance workload, save labour cost, easy to use.
Description of drawings: Fig. 1 is the utility model structural representation;
1. the outlet of dirty wind, 2. fresh inlet, 3. dirty wind inlet, 4. new wind outlet, 5. blower fan, 6. heat exchanger, 7. housing.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of fresh air-changing device of the utility model is made up of housing 7, blower fan 5, heat exchanger 6, it is characterized in that: the top in the housing 7 respectively outwards is respectively arranged with two blower fans, 5, two blower fans, 5 air ports; Be provided with in the central authorities of housing 7 that cross flow is static, flat plate heat exchanger 6; Be provided with dirty wind outlet 1 on the upper left side of housing 7, the lower left is provided with fresh inlet 2, and the upper right side is provided with new wind outlet 4, and the lower right is provided with dirty wind inlet 3.During concrete enforcement, two jiaos in the housing on the same horizontal line in top are respectively arranged with low noise outer rotor centrifugal blower, are provided with dirty wind outlet on the housing upper left side, and the lower left is provided with fresh inlet, the upper right side is provided with new wind outlet, and the lower right is provided with dirty wind inlet; Blower fan unit wall is coated with novel sound-absorbing material, filter is housed in unit filters, and effectively prevents in dust and the harmful substance inlet chamber, keeps room air fresh; In order to be easy to the gas channel in the placement machine, to dwindle machine volume, adopted static, the flat plate heat exchanger of cross flow, make the direction of motion of hot and cold air vertical mutually.
The utility model heat exchange computing formula:
Summer: indoor feed air temperature=outdoor temperature-(outdoor temperature-indoor temperature) X heat exchanger effectiveness;
Example: 32 ℃-(32 ℃-26 ℃) X 70%=27.8 ℃
As shown in Figure 3, heat exchange computing formula:
Winter: indoor feed air temperature=(indoor temperature-outdoor temperature) X heat exchanger effectiveness+outdoor temperature;
Example: (20 ℃-0 ℃) X 70%+0 ℃=14 ℃
Air-flow belongs to the heat convection character in the turbulent boundary in heat exchanger.Therefore its heat exchange is very sufficient, can reach very high exchange rate.This device places the furred ceiling room, and not taking the interior space does not influence the finishing effect, and remotely-controlled operation has the two kinds of air-out modes in round air port and square air port.Unit has reduced cold and hot treatment facility, and hot yield reaches more than 70%, has reduced operating cost to a great extent, has realized environmental protection and energy-efficient high unity.
