Description
Technical field
The utility model relates to air-conditioning system, particularly a kind of bypass type VMC.
Background technology
Cold district and severe cold area winter indoor, ventilation of windowing may be very little.Breathe required new wind for solving indoor occupant, dilution interior architecture pollutes the various pernicious gases distributed, and necessaryly arranges VMC.
The central air-conditioning VMC that current routine is arranged, heating adopts circulating hot water, is provided by municipal thermal source or boiler room.Some building, has certain distance apart from municipal thermal source pipeline, and because the reason such as the character of building and fire-fighting spacing, cannot arrange boiler room.
And adopting the vaporation-type brand new air processing group of refrigerant, off-premises station is difficult to run in the environment of less than-5 DEG C in the winter time.
If only arrange total-heat exchanger to process new wind, when outdoor low temperature, be difficult to the parameter of Fresh air handing to designing requirement, so often give indoor feeding cold wind.
According to above situation, design is a kind of simple, can with the VMC in winter of wet monsoon system coupling, be just extremely necessary.
Utility model content
The purpose of this utility model is to provide a kind of bypass type VMC, mainly solves the technical problem existing for above-mentioned prior art, it be do not need a kind of winter circulating hot water, can and summer air-conditioning wind system close the VMC established.
For achieving the above object, the technical solution of the utility model is:
A kind of bypass type VMC, is characterized in that: it comprises combined air conditioning box, total-heat exchanger and electrical heating wet-membrane humidifier; The indoor fresh air pipe of this combined air conditioning box is connected total-heat exchanger with indoor exhaust wind pipe; This total-heat exchanger also has the outdoor fresh wind tube and outdoor exhaust duct that are connected to outdoor; These indoor have two-way return air arm, first via return air arm be connected to combined air conditioning box and with indoor fresh air manifold merge send into filter, refrigeration mechanism, the second road return air arm and indoor exhaust wind manifold close; This combined air conditioning box is also connected with indoor ajutage, has bypass fresh wind tube between this indoor ajutage and indoor fresh air pipe, and this bypass fresh wind tube is provided with electrical heating wet-membrane humidifier.
Described bypass type VMC, is characterized in that: this indoor ajutage and indoor return air pipe pass through machine room place and arrange fire resisting damper.
Described bypass type VMC, it is characterized in that: this indoor second road return air arm arranges first and electronicly splits multi-clack control valve, this indoor fresh air pipe arranges second and electronicly splits multi-clack control valve near combined air conditioning box place, this bypass fresh wind tube is arranged the 3rd and electronicly split multi-clack control valve, this indoor ajutage arranges the 4th and electronicly splits multi-clack control valve near combined air conditioning box place.
The utility model has the advantages that:
1, when the utility model uses, as long as arrange a bypass pipe winter between new wind and ajutage, just can when there is no Air-conditioning Cycle hot water, by Fresh air handing to the parameter required by designing.Adopt fewer investment, do not increase Air Conditioning Facilities area, reach design effect.
2, the utility model by control electronic split multi-clack control valve carry out summer and winter mode of operation switching.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1-combined air conditioning box; 2-total-heat exchanger; 3-electrical heating wet-membrane humidifier; FD-fire resisting damper; M1, M2, M3, M4-are electronic splits multi-clack control valve; SF-ajutage; HF-backwind tube; XF-fresh wind tube; PF-exhaust duct.
Detailed description of the invention
Refer to Fig. 1, the utility model discloses a kind of bypass type VMC.As shown in the figure: it comprises combined air conditioning box 1, total-heat exchanger 2 and electrical heating wet-membrane humidifier 3.Wherein: this combined air conditioning box 1 comprises and comprises mixing end, fillter section, surface cooling section, fan section, and the specified heat recovery efficiency of this total-heat exchanger 2 is not less than 60%, and this electrical heating wet-membrane humidifier 3 comprises wet-film humidifying section, electric heater section.The indoor fresh air pipe XF of this combined air conditioning box 1 is connected total-heat exchanger 2 with indoor exhaust wind pipe HF; This total-heat exchanger 2 also has the outdoor fresh wind tube XF and outdoor exhaust duct PF that are connected to outdoor; These indoor have two-way return air arm, and first via return air arm HF is connected to combined air conditioning box 1 and mixes with indoor fresh air pipe XF and send into fillter section, surface cooling section, and the second road return air arm HF and indoor exhaust wind pipe PF converges; This combined air conditioning box 1 is also connected with indoor ajutage SF, has bypass fresh wind tube XF between this indoor ajutage SF and indoor fresh air pipe XF, and this bypass fresh wind tube XF is provided with electrical heating wet-membrane humidifier 3.
This indoor ajutage SF and the second road backwind tube pass through machine room place and arrange fire resisting damper FD respectively.
This indoor second road return air arm arranges first and electronicly splits multi-clack control valve, this indoor fresh air pipe arranges second and electronicly splits multi-clack control valve near combined air conditioning box 1 place, this bypass fresh wind tube is arranged the 3rd and electronicly split multi-clack control valve, this indoor ajutage arranges the 4th and electronicly splits multi-clack control valve near combined air conditioning box 1 place.
When the utility model uses, summer new wind by outdoor adopt into, enter total-heat exchanger 2 and carry out heat exchange with air draft, then enter in combined air conditioning box 1 and mix with return air, through filtration, freeze after send in room.In room, return air is divided into two branch roads, and major part enters combined air conditioning box 1 and mixes with new wind, and fraction to carry out after heat exchange outside discharge chamber through total-heat exchanger 2 with new wind.
When the utility model uses, winter new wind by outdoor adopt into, enter total-heat exchanger 2 and carry out heat exchange with air draft, then enter bypass branch, enter in electrical heating wet-membrane humidifier 3, send in room after heating, humidification.In room, air draft to be carried out after heat exchange outside discharge chamber through total-heat exchanger and new wind.
The new wind in winter is sent into indoor through bypass branch, without combined air conditioning box process, can save the operation energy consumption of combined air conditioning box inner blower like this.
Winter, new wind was in bypass branch, adopted that new wind heats by simple equipment, humidification, and design parameter has been arrived in process, improves IAQ in winter.
The utility model switches in the operation in summer and winter electronicly to be split multi-clack control valve to carry out mainly through controlling.When using summer, M1, M2 and M4 open, and M3 closes.When use in winter, M3 opens, and M1, M2 and M4 close.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
