Description
Technical field
The present invention relates to the air-conditioning unit, particularly a kind of assembled air-conditioner unit with the ventilation bypass.
Background technology
The assembled air-conditioner unit structurally is made up of wind inlet section, fillter section, air-treatment function section, fan section, muffler section and air supply section, generally is used for bigger place, space, like large supermarket, market, exhibition center, airport, subway station etc.Often there is the surplus humidity load of metastable waste heat in such place throughout the year, and system needs to send cold wind throughout the year or for a long time or guarantee certain fresh-air ventilation number of times.Transition season or winter, can handpiece Water Chilling Units out of service, directly outdoor cold air is delivered to indoorly, promptly can reach cool effect, to reach the purpose of saving air conditioning energy consumption by the operation of ventilation operating mode.
For addressing the above problem, common way has two kinds: a kind of is to utilize the assembled air-conditioner unit to move by the ventilation operating mode.(comprise in the various functional sections such as surface cooling section, dash section, bringing-up section, humidifier section, dehumidifying section one or more) resistance is bigger because the air-treatment function section; Increased the pressure loss of wind system under the ventilation operating mode meaninglessly; Cause the waste of fan operation energy consumption, be unfavorable for energy-conservation; Another kind method is established the breeze fan of ventilation operating mode in addition, and this method has increased initial outlay, and idle, non-air-conditioning season of pressure fan in air-conditioning season the assembled air-conditioner unit idle, utilization rate of equipment and installations is not high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of assembled air-conditioner unit with the ventilation bypass, the energy consumption in the time of can significantly reducing the assembled air-conditioner unit and be used to ventilate operating mode, and help reducing the initial cost of air-conditioning system.
The technical solution adopted for the present invention to solve the technical problems is following:
A kind of assembled air-conditioner unit of the present invention with the ventilation bypass; Comprise wind inlet section, fillter section, air-treatment function section, fan section, muffler section and air supply section); It is characterized in that: offer preceding by-pass port, back by-pass port on the forward and backward cabinet of said air-treatment function section respectively; Be connected to form the ventilation bypass with the bypass airduct between preceding by-pass port, back by-pass port, the bypass airduct is provided with the bypass air-valve of control ventilation bypass switching.
The invention has the beneficial effects as follows; Because of bypass wind path resistance much smaller than air-treatment function section resistance; And the bypass wind path forms parallelly connected relation with the air-treatment function section; Unit main pipe rail characteristic curve is greatly slowed down; When the assembled air-conditioner unit is used to ventilate operating mode; Total negotiability of unit is much larger than air conditioning condition, in conjunction with fan speed regulation technology (speed-changing draught fan or frequency conversion fan), and the energy consumption in the time of can significantly reducing the assembled air-conditioner unit and be used to ventilate operating mode.Also needn't establish blower fan in addition, reduce the initial outlay of air-conditioning system.
Description of drawings
This specification comprises following two width of cloth accompanying drawings:
Fig. 1 is the structural representation of a kind of assembled air-conditioner unit embodiment 1 with the ventilation bypass of the present invention;
Fig. 2 is the structural representation of a kind of assembled air-conditioner unit embodiment 2 with the ventilation bypass of the present invention.
Parts shown in the figure, toponym and pairing mark: wind inlet section 11, fillter section 12, air-treatment function section 13, fan section 14, muffler section 15, air supply section 16, bypass airduct 20, bypass air-valve 21, preceding by-pass port 22, back by-pass port 23.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
With reference to Fig. 1; A kind of assembled air-conditioner unit of the present invention with the ventilation bypass; Comprise wind inlet section 11, fillter section 12, air-treatment function section 13, fan section 14, muffler section 15 and air supply section 16; By-pass port 22, back by-pass port 23 before offering respectively on the forward and backward cabinet of said air-treatment function section 13; Before by- pass port 22,23 of the by-pass ports in back be connected to form the ventilation bypass with bypass airduct 20, bypass airduct 20 is provided with the bypass air-valve 21 of control ventilation bypass switching.Wherein air-treatment function section 13 generally includes surface cooling section, dash section, bringing-up section, humidifier section, spray section, dehumidifying section etc., and the needs according to air handling process in the practical application are selected wherein one or more functions.Bypass air-valve 21 is manually perhaps electronic, and the size of bypass airduct 20 and bypass air-valve 21 is confirmed according to the air quantity of unit.
After taking technique scheme, under the air conditioning condition, close bypass air-valve 21, air is handled back (cooling, heating, humidification, dehumidifying etc.) through air-treatment function section 13 and is delivered to air conditioning area again; During the ventilation operating mode; Open bypass air-valve 21; Because of 20,21,22,23 drag overalls of bypass wind path much smaller than air-treatment function section 13 resistances; And the bypass wind path forms parallelly connected relation with air-treatment function section 13; Can know that by principle of parallel unit main pipe rail characteristic curve greatly slows down, the total negotiability of unit was much larger than air conditioning condition (bypass air-valve 21 cuts out) when bypass air-valve 21 was opened.In conjunction with fan speed regulation technology (speed-changing draught fan or frequency conversion fan), the energy consumption in the time of can significantly reducing said assembled air-conditioner unit and be used to ventilate operating mode reaches energy-conservation effect.
In by the embodiment shown in Fig. 11, said preceding by-pass port 22 is arranged between fillter section 12 and the air-treatment function section 13.In by the embodiment shown in Fig. 22, said preceding by-pass port 22 is arranged between wind inlet section 11 and the air-treatment function section 13.
Existing according to certain series of combination formula air processing machine set product, its energy-saving effect is described further.Be divided into 400Pa, 600Pa, 800Pa, air quantity 120000m according to the outer overbottom pressure of machine
3/ h, fan efficiency is 0.75 machine group analysis.Each functional section drag losses is following: air-treatment function section 380Pa (surface cooling section 140Pa, dash section 80Pa, bringing-up section 80Pa, humidifier section 80Pa), outlet and inlet section are 20Pa, muffler section 30Pa, bypass airduct drag overall 40Pa:
According to aforementioned calculation, for the unit of the outer overbottom pressure of three kinds of different machines, the ventilation operating mode is respectively 40%, 32.4% and 27.2% with respect to the air conditioning condition fractional energy savings.
Be example with Shenzhen, Chengdu, typical case subway station, Pekinese respectively, the unit air quantity is 120000m
3/ h, the outer overbottom pressure of machine is 600Pa, moves 18h every day, and electricity price is 0.7 yuan/kW.h, and the annual operating cost situation is following:
Can know that from last table ventilation operating mode longer then energy saving space running time is big more.
Some principles of a kind of assembled air-conditioner unit with the ventilation bypass of the above the present invention that just explains through diagrams; Be not be the present invention to be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
