The purpose of this utility model is to be realized by following technical proposals: a kind of return air heat retracting device, including recuperation of heat shell Body, is provided with outdoor air inlet and outdoor exhaust outlet in the side of recuperation of heat housing, and the opposite side at recuperation of heat housing is provided with indoor Return air inlet, indoor return air mouth is correspondingly arranged with outdoor air inlet, it is characterised in that: also include air outlet under indoor, air filter Net and heat exchanging core, described heat exchanging core is stuck in the middle part of recuperation of heat housing, and air filter screen is arranged at heat exchanging core Outside, indoor lower air outlet and indoor return air mouth are located at the same side of heat exchanging core, outdoor air inlet and outdoor exhaust outlet and are set The same side in heat exchanging core.

As a kind of optimal way, wherein: also include that air wetting film, air wetting film are connected near indoor return air mouth On recuperation of heat housing.

As a kind of optimal way, wherein: also include that condensed water water inlet pipe, the bottom of described condensed water water inlet pipe are placed in air In humidification membrane.

As a kind of optimal way, wherein: described heat exchanging core is rhombogen, four sides of its rhombus respective chamber/chambers respectively Air outlet under interior return air inlet, outdoor air inlet, outdoor exhaust outlet and indoor.

In this utility model, the effect of part is as follows:

Heat exchanging core: carry out heat exchange when the different passages of heat exchanger core flow through for the new wind of indoor return air and outdoor, will be from The wind entered in indoor return air entrance is discharged after heat exchanging core at outdoor wind exhausting outlet, is entered air intake porch, outdoor The wind entered is discharged from indoor fresh air exit after heat exchanging core, it is achieved pre-cooling of fresh air and preheating, reaches energy-conservation purpose.

Compared with prior art, the beneficial effects of the utility model: this utility model provides a kind of band wet-film humidifying refrigerating function New wind heat retracting device, in new wind ventilating system, reduces the leaving air temp of new blower fan, reduces new wind load;Reclaim Utilize the cold in air conditioner condensate water, increase semen donors.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model return air heat retracting device.

In figure: outdoor air inlet-1, outdoor exhaust outlet-2, indoor lower air outlet-3, indoor return air mouth-4, heat Exchange core body-5, air wetting film-6, condensed water water inlet pipe-7, air filter screen-8.

Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is further described.

All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive spy Beyond matter and/or step, all can combine by any way, unless specifically stated otherwise, all can by other equivalence or there is similar mesh Alternative features replaced, i.e. unless specifically stated otherwise, in a series of equivalences of each feature or similar characteristics Embodiment.

As it is shown in figure 1, this utility model return air heat retracting device, including recuperation of heat housing, set in the side of recuperation of heat housing Having family external air inlet mouth 1, outdoor exhaust outlet 2, the opposite side at recuperation of heat housing is provided with indoor return air mouth 4, indoor return air mouth 4 It is correspondingly arranged with the position of outdoor air inlet 1.It addition, this utility model return air heat retracting device also include air outlet 3 under indoor, Air filter screen 8, heat exchanging core 5, air wetting film 6 and condensed water water inlet pipe 7.Air wetting film 6 is connected near room On the recuperation of heat housing of interior return air inlet 4.The bottom of described condensed water water inlet pipe 7 is placed in air wetting film 6.Described heat is handed over Changing core body 5 and be stuck in the middle part of recuperation of heat housing, air filter screen 8 is arranged at the outside of heat exchanging core 5, indoor lower air outlet 3 It is located at heat exchanger core with the same side that indoor return air mouth 4 is located at heat exchanging core 5, outdoor air inlet 1 and outdoor exhaust outlet 2 The same side of body 5.Described heat exchanging core 5 is rhombogen, return air inlet 4, room in four sides of its rhombus respective chamber/chambers respectively Air outlet 3 under external air inlet mouth 1, outdoor exhaust outlet 2 and indoor.

In running, the heat exchanging core in this utility model return air heat retracting device can realize the energy regenerating to air draft, Pre-cooling or preheating for new wind.Meanwhile, under summer condition, available condensed water water inlet pipe adds water into wet film, is used for Humidification, carries out pretreatment to return air, reduces return air temperature, improves return air and the sensible heat exchange efficiency of new wind.
