Description
Technical field
The utility model belongs to Heating, Ventilation and Air Conditioning (HVAC) Technology field, is specifically related to hotel kitchen ventilation unit.
Background technology
Hotel kitchen room well-ventilated is also the guarantee that kitchen work personnel normally work.But construction unit and architectural discipline are paid attention to not to this in practice, on the other hand due to kitchen technological design specialty and Design of ventilation professional between coordinates inadequate, design of kitchen is lacked experience, and kitchen ventilation designs unreasonable situation and often occurs.For north cold area, the contradiction excessive due to the kitchen ventilation wind heating energy consumption that causes that kitchen environment is poor, dining room room temperature in winter is on the low side, new is particularly outstanding.When construction drawing design, architectural discipline is for catering to construction unit's suggestion, and make fan house area, ventilation pipe well area less than normal, position is unreasonable.The kitchen technological design of specialty is delayed simultaneously, and Design of Ventilation System also can only provide kitchen technique perfect not to the utmost to carry out by architectural discipline.After civil engineering completion, when applying unit determines kitchen technique, design of kitchen is caused to do over again.Because civil engineering completes, for kitchen ventilation poor effect leaves hidden danger.
Person cooks operation room adopts the indoor air circulation mode systems such as fan coil, and oil smoke in kitchen, vapour content are higher, long-term this type of foul atmosphere of circulation, certainly will cause oil smoke to be attached to fan coil surface, greatly increase heat transfer resistance and flowing resistance, reduce cooling effect.In the course of time, equipment is caused to lose refrigerating capacity.
Star hotel's diverse in function, architectural composition are complicated, and in kitchen, because technological process is numerous and the restriction of architectural composition makes the design of ventilating system very thorny.In addition, the kitchen technological design in general hotel delayed, therefore, if the Design of ventilation in kitchen can not with its technique effective coordination, kitchen ventilation will be caused smooth, and indoor environment is severe.Deep fat flue gas in dish cooking process is full of whole kitchen space, and the health not only endangering cook reduces operating efficiency, has a strong impact on quality and the image in hotel.
Summary of the invention
The utility model is for above-mentioned technical problem, a kind of hotel kitchen ventilation unit is provided, described kitchen has air channel, enclosure, backing plate and the kitchen range top, described ventilation unit comprises operating space gas skirt, gas trap hood and ventilating part, described ventilating part is made up of the first air exhauster, the second air exhauster, air-conditioning pipe I, air-conditioning pipe II, air-conditioning pipe III, air conditioner, air vent, and described air-conditioning pipe III is communicated with air conditioner through air channel; Air-conditioning pipe III is communicated with air-conditioning pipe I and the air-conditioning pipe II of gas skirt both sides, operating space; Second air exhauster is communicated with gas trap hood through exhaust duct; First air exhauster is communicated with operating space gas skirt through exhaust duct; Several air vents laid by air-conditioning pipe III.
As preferred technical scheme, the cover mouth cross dimensions of described enclosure is with close with cigarette diffusion region floor projection.
As preferred technical scheme, described enclosure is umbrella hood, and the tilting back angle in both sides is 120 degree of-140 degree, and enclosure is provided with the high shirt rim of 0.2-0.3m.
As preferred technical scheme, described exhaust duct is provided with air draft shutter, blade from inside to outside successively, and blade is as preferred technical scheme, and regulate through air-valve, exhaust duct is fixed through flange.
As preferred technical scheme, exhaust duct adopts the Plate Welding of thick 1.5mm ~ 3mm.
As preferred technical scheme, the long 8 ~ 12m of exhaust duct, has the gradient of 5%.
The beneficial effects of the utility model are:
1, cook's operating area arranges separately new wind, to ensure the needs that cook breathes, maintains operating space uniform temperature simultaneously.
2, air conditioner adopts single flow air-conditioning, and air intake all comes from outdoor, and indoor surplus air all drains into outdoor, and air-conditioning equipment is return air not.
3, entirety air-supply in kitchen mainly improves cook working region air quality, ensure that cook's operation has sufficient fresh air to supplement and air-conditioning temperature-reducing, it is as far as possible little that this air-supply air-flow entrainments air quantity, and coverage rate is as far as possible large, avoids the strong blowing of cook and do not accommodate and affect stove fire.
4, kitchen ventilation pipeline should not adopt civil engineering air channel; Avoid arranging long horizontal duct, air channel arranges the gradient and steams condensation ponding to discharge water as far as possible; Exhaust blower is located at top, kitchen and makes most of exhaust duct be in negative pressure state, avoids smelling out.
5, during cooking operation, distributing of oil smoke is that emission is maximum when food enters to get away oil cauldron, other times are relatively less, if exhaust air rate is completely by calculating this moment, certainly will cause that need to join exhaust air rate excessive, the exhaust blower of relatively large number must be selected, and this novel shirt rim that suitable height is set, designing and arranging air quantity can be reduced, because the rising oil smoke of certain volume can be held in space, shirt rim, extend the drain time concentrated and distribute oil smoke like this, then unit interval exhaust smoke level reduces, and improves oil smoke lifting power simultaneously.
6, this ventilation unit adopts air conditioner both sides for kitchen air-supply, and the structure of middle exhausting, because air-conditioner wind is sent in gas skirt both sides, outside cold wind wraps the deep fat flue gas that inner side produces, make it to spread, and under being gathered in gas skirt, concentrate pump drainage to go out by gas skirt.This mode can make oil smoke be controlled in certain limit, thus does not affect other regions, makes kitchen keep clean and comfortable.The region that this external local likely produces hot gas adopts an auxiliary air exhauster exhausting, keeps ventilation effect good in kitchen.
