New wind is handled and conglomerate integration purification air-conditioning unit
Technical field
The utility model relates to a kind of air-conditioning unit, particularly relates to a kind of new wind and handles and conglomerate integration purification air-conditioning unit.
Background technology
Existing air-conditioning unit, its mechanism is that certain return air is mixed with new wind, by sending in the air compartment after the cold and hot processing, make the air-conditioning unit on performance, be restricted like this: on the one hand, if with energy-conservation is purpose, then the return air amount can not be too big, and this can cause the indoor air-changing number of times to reduce, and clean-up effect is not obvious; On the other hand, if want clean-up effect obvious, then the return air amount must increase, indoor air-changing increased frequency, but energy consumption increase when causing cold and hot processing like this, and unit is energy-conservation inadequately.
The utility model content
The utility model purpose: the utility model is to handle and conglomerate integration purification air-conditioning unit in order to solve the deficiencies in the prior art, provide a kind of both energy-conservation, can satisfy again the new wind that purifies requirement.
Technical scheme: new wind described in the utility model is handled and conglomerate integration purification air-conditioning unit, its objective is such realization: a kind of new wind is handled and conglomerate integration purification air-conditioning unit, wind pushing cavity by new wind chamber, return air chamber and the casing rear portion of casing, casing front portion is formed, and described new wind is disposed with fresh inlet, fresh inlet roughing efficiency air filter, heat exchanger by the air current flow order in the chamber; Be disposed with return air inlet, return air inlet roughing efficiency air filter by the air current flow order in the described return air chamber; Be disposed with blower fan dividing plate, pressure fan assembly, medium effeciency filter, air outlet by the air current flow order in the described wind pushing cavity; Be provided with the air-valve dividing plate between integral body that described new wind chamber and return air chamber are formed and the wind pushing cavity.
As optimization: be provided with new air-valve before the described blower fan valve curtain;
As optimization: be provided with air returning valve before the described blower fan valve curtain.
Beneficial effect: the utility model compared with prior art utilizes new wind to handle the indoor hot humidity load of air conditioning, and indoor fresh air is provided simultaneously; Utilize with mixing of return air to increase air mass flow, improve the indoor air clean degree.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment:
New as shown in drawings wind is handled and conglomerate integration purification air-conditioning unit, is made up of the wind pushing cavity 4 at new wind chamber 2, return air chamber 3 and the casing rear portion of casing 1, casing front portion.
Be disposed with fresh inlet 5, fresh inlet roughing efficiency air filter 6, heat exchanger 7, new air-valve 15 by the air current flow order in the described new wind chamber 2;
Described heat exchanger 7 places in the new wind chamber 2, and fresh inlet 5 places are provided with fresh inlet roughing efficiency air filter 6 in new wind chamber 2
Be disposed with return air inlet 8, return air inlet roughing efficiency air filter 9, air returning valve 16 by the air current flow order in the described return air chamber 3;
Return air inlet 8 places are provided with return air inlet roughing efficiency air filter 9 in return air chamber 3.
Be disposed with blower fan dividing plate 10, pressure fan assembly 11, medium effeciency filter 12, air outlet 13 by the air current flow order in the described wind pushing cavity 4;
Blower fan dividing plate 10 is separated into two parts with casing, during operation wherein a sidewind be malleation, opposite side is a negative pressure.
Pressure fan assembly 11 links to each other with blower fan dividing plate 10, and the air-flow downside medium effeciency filter 12 that all is in new wind chamber 2 and return air chamber 3 places between integral body that the new wind of the air-flow front end chamber 2 of the air-flow downside of pressure fan assembly 11, air outlet 13 and return air chamber 3 form and the wind pushing cavity 4 and is provided with air-valve dividing plate 14.
During unit operation, pressure fan assembly 11 is opened, suck the mixed airflow of new wind and return air, after filtering, medium effeciency filter 12 sends into casing 1 by air outlet 13, new wind is entered by fresh inlet 5, filter through fresh inlet roughing efficiency air filter 6, mix with the return air air-flow by after the hot wet process of heat exchanger 7 again; Return air is entered by return air inlet 8, mixes with new wind after return air inlet roughing efficiency air filter 9 filters, and is sucked by pressure fan assembly 11.
By hot and cold MEDIA FLOW mistake, finish heat exchange in the heat exchanger 7 in the new wind chamber 2, handle the wet parameter of air heat with the new wind air that flows through.
