Energy consumption, air quality) reset fresh air volume size and carry out adaptive judgement adjusting, different operating modes are flexibly solved to Xingfeng capsule
Needs of problems, control accuracy higher, is suitable for user to energy consumption, the demand of air quality.
It should be noted that fresh air quantity control pressure pertinence refers to that fresh air volume is quiet by new fan inlet and new fan outlet
The influence of fluctuations of pressure, causes the actual suction fresh air volume of new wind turbine unstable uncontrolled, and pressure fan converting operation different frequency is straight
Connecing influences new wind turbine exit static pressure, and fresh air volume fluctuation causes new, backwind tube resistance change again, causes new wind turbine inlet pressure ripple
Dynamic, pressure difference is uncontrolled before and after new wind turbine, therefore it is impossible that fresh air volume is constant.
Fresh air quantity control pressure independence, with pressure pertinence just on the contrary, being directly controlled to fresh air volume size, no
Pipe causes how the factor of pressure difference before and after new wind turbine changes, and control strategy only focuses on whether fresh air volume changes, and to fresh air
Amount carries out constant control, therefore is called fresh air quantity control pressure independence.

The air conditioner of the marine air-conditioning system integrates new wind turbine and fresh air quantity control device in one, and makes convertible frequency air-conditioner
Device, compared to the technical solution that common air-conditioning device+engineering system additionally increases by 1 set of new wind turbine and fresh air volume detection limit device, this collection
Fresh air volume constant control is successfully realized into air conditioner, i.e. fresh air volume stability is no longer caused by air conditioner pressure fan frequency conversion operating
The conversion of fresh air exit static pressure influence, also no longer by new, return air duct since engineering construction adjustment causes fresh air measurement smart
Spend decline influence, it also avoid fresh air volume measurement accuracy decline in the case of field conduct revision error it is difficult the problem of and most
Solve the problems, such as that fresh air volume is influenced to cause to be precisely controlled by the above problem eventually.It is empty that the air conditioner more saves equipment installation
Between, it is more useful in ship air conditioning system with variable and applies.
The marine air-conditioning system has the characteristics that fresh air volume can reset constant control, the main difference compared with common air-conditioning device
Point is, is integrated with new wind turbine 4, the wind that can be accurately measured fresh air intake that can overcome exterior fresh wind tube crushing
Measurement component, fresh air air inlet adjustment valve 5 and return air air inlet adjustment valve 6 etc..Due to the indirect hydrostatic measuring point present position of fresh air volume
Pressure-stabilizing section (at 7 place of the first static pressure detection piece) and air-ducting ring flow velocity uniform segment are (where the second static pressure detection piece 8 before inlet air
Place) it is air flow field settling position, two in the operating frequency range of unit frequency common 50%~100% of blowing at this structure
It is minimum to locate measuring point pressure difference degree of susceptibility, measurement effect is best.
Since the marine air-conditioning system fresh air volume can be reset, fresh air volume can be adjusted according to duty requirements, such as
Ship's navigation marine site, can suitably reduce new wind ratio (being allowed to be in 30-40%) to ensure that fresh air is born to Tropical Ocean Area or proximal pole
Lotus meets that the regulation and control of marine air conditioning temperature require, and reduces load., can in the more suitable environment of spring and autumn transition season or environment temperature
New wind ratio (being allowed to be in 40-50%) is properly increased to improve air quality, it is negative with reducing air-conditioning input using new wind load
Lotus, had not only ensured that the regulation and control of marine air conditioning temperature required, but also can reduce energy consumption, improved air quality.
As ship pull in shore temporarily habitation personnel largely reduce when, new wind ratio can be reduced to greatest extent and (be allowed to be in
10%-30%), to reduce the air conditioning energy consumption that fresh air undertakes.
