Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment：
With reference to Fig. 1, a kind of central air-conditioning combines wind cabinet, including cabinet 1, air inlet, air outlet 3, filtration, surface cooler
51st, wind turbine 8, heater 6 and humidifier 7, the air inlet and the air outlet 3 are arranged on the side of cabinet 1, the filtering
Structure, the surface cooler 51, the wind turbine 8, the heater 6 and the humidifier 7 are arranged in the cabinet 1, institute
It states air inlet and includes fresh wind port 21 and return air inlet 22, the filtration includes primarily efficient filter layer 41 and middle high efficiency filter layer 42,
At least two surface coolers 51 are provided in the cabinet 1, and side is provided at the carrier ring on 51 side of surface cooler
Port valve 52；
Be disposed in the cabinet 1 the primarily efficient filter layer 41, the surface cooler 51, the heater 6, it is described plus
Wet device 7, the wind turbine 8 and the middle high efficiency filter layer 42, the air outlet 3 are arranged on by the middle high efficiency filter layer 42.
At least three by-passing valves 52 are provided on the carrier ring on 51 side of surface cooler.
The by-passing valve 52 is manual modulation valve or electric control valve or pneumatic control valve.
Filter hole in the primarily efficient filter layer 41 is more than the filter hole of the middle high efficiency filter layer 42.
Total actual internal area of multiple by-passing valves 52 is not less than the actual internal area of the surface cooler 51.
Outside 21 junction chamber of fresh wind port, in 22 junction chamber of return air inlet；In 3 junction chamber of air outlet.
It is less than the season of indoor objects air-conditioner temperature and humidity in ambient temperature and humidity, in order to save the energy, just
Chilled water (chilled water for coming from central air-conditioning refrigeration host computer) necessary to the surface cooler of wind cabinet is combined under reason condition stops supplying
It gives, it is only necessary to by increasing fresh air volume, the temperature and humidity of room air can be handled to mesh with the outdoor air of low temperature and low humidity
Scale value.After by-passing valve is opened, since the air drag in by-passing valve is far below the air drag of surface cooler, air can be preferential
It circulates from by-passing valve.In the case, it combines the surface cooler in wind cabinet and is actually just no longer participate in air-treatment, therefore when sky
When air-flow is through surface cooler cross section, in order to reduce unnecessary flow resistance, all by-passing valves are all opened so that most of empty
Gas it is all natural through the bypass passageways where each by-passing valve directly around the larger surface cooler of resistance, and into downstream, thus make
It obtains and be used to the part of the air flow resistance of aforementioned surface cooler be overcome to be saved in fan energy consumption, it is achieved thereby that further section
It can benefit.
Specifically, under above-mentioned operational mode, indoor return air enters combination wind cabinet by return air inlet, and outdoor fresh air passes through new
Air port enters combination wind cabinet, is tentatively filtered by primarily efficient filter layer first after being mixed in mixing section, then flows through bypass
The cold cross section of table of valve and surface cooler composition.Since by-passing valve is fully open at this time so that most air-flow is all through by-passing valve
The bypass gap flow paths downstream at place flows through larger resistance caused by surface cooler so as to significantly avoid.Due to outdoor fresh air
Temperature and humidity be below room conditioning target temperature and humidity, as long as controlling sufficiently large fresh air/air returning ratio, combine wind
The temperature and humidity of the mixing air of cabinet interlude is also less than air-conditioning target temperature and humidity, therefore is followed by flowing
By accurate temperature adjustment and conditioning during heated device and humidifier, target air-conditioner temperature and humidity are finally reached, then
Under the driving of wind turbine ajutage is sent to through air outlet again in after high efficiency filter layer purification.Obviously, using the utility model, no
But the energy-saving benefit that combination wind cabinet deactivates refrigeration host computer low-temperature receiver in low temperature and low humidity season is maintained, further reduces combination wind
The cycle windage of cabinet, so as to reduce the operation energy consumption of wind turbine, further obtains energy-saving benefit.
It, only need to be by-passing valve whole in outdoor environment temperature and humidity higher than indoor objects air-conditioner temperature and the season of humidity
It closes, surface cooler low-temperature receiver side chilled water restores supply, then the utility model device combines wind cabinet with conventional center air-conditioning does not have area
Not.Under this operating condition, only difference is that, the mixing air being made of return air and fresh air is flowing through surface cooler cross section
When, due to by-passing valve Close All, the fin heat-transfer surface of each surface cooler can only be passed through, and cooled down and dehumidified.It leaves aforementioned
Behind surface cooler cross section, accurate temperature adjustment and damping successively by heater and humidifier are remained, and under the driving of wind turbine
In ajutage is sent to through air outlet again after high efficiency filter layer purification.
The utility model is characterized in that it is independent that the surface cooler in combination wind cabinet is divided into several on interface windward
Part passes through by-passing valve connection and sealing between each part.Room air is below in ambient temperature and humidity to adjust
In the season of target temperature and humidity, surface cooler stops supply chilled water, and the other component for combining wind cabinet works as usual, thus leads to
It crosses using extraneous natural cooling source, can not only realize air-treatment target, but also energy consumption for cooling can be saved.
The embodiment of the utility model is without being limited thereto, according to the above of the utility model, utilizes the general of this field
Logical technological know-how and customary means, under the premise of the above-mentioned basic fundamental thought of the utility model is not departed from, the utility model may be used also
To make the modification of other diversified forms, replacement or change, all fall within the utility model rights protection scope.
