Background technology
The LED display of outdoor large is a 21 century advertising Development Trend, has display effect and flexibility that the conventional ads media can not be compared, is applicable to all trades and professions widely.Existing various places government all encourages to carry out using the outdoor LED screen.
The LED display of outdoor large is installed in outdoor; Move every day more than 16 hours nearly all in operation in 1 year 365 days, electronic device produces a large amount of heats during operation; Cause the display screen environment temperature to raise; Therefore, for guaranteeing the normal long-time running of this display screen, the system that need install an air-conditioner is to the processing of lowering the temperature of this display screen.
The LED advertisement cabinet cooling installation of outdoor large generally all adopts special-purpose air conditioner in machine room or common air-conditioning at present.But because the difference of service condition, the outdoor LED display screen cooling installation no matter adopt special-purpose air conditioner in machine room or the new blower fan of common air-conditioning, all exists a lot of not enough.The general requirement of LED display temperature control of outdoor large is below 40 ℃; Consider that from the economical aspect of electricity consumption the air-conditioning design temperature is preferably 35-40 ℃, and adopt air conditioner in machine room or common air-conditioning design temperature all well below 35--40 ℃; Cause operation of air conditioner time lengthening, power consumption increases.In addition, the general requirement of the LED display temperature of outdoor large control is below 40 ℃, and the air-conditioning design temperature is 35-40 ℃; Return air temperature is higher; Suitable with China highest temperature in summer, therefore nonsensical from the LED display return air of outdoor large, can be directly from outdoor environment return air.From the benefit of outdoor environment return air be, than under the low condition, air-conditioning only need move blower fan at temperature, and compressor need not move, and saves the air-conditioning power consumption greatly; Low temperature lower compression machine does not move, and need not increase the cryogenic refrigeration module, has improved system reliability greatly.Existing air-conditioning all can not satisfy above requirement.
The utility model content
The utility model technical problem to be solved: to the deficiency of prior art; A kind of control method that makes the uniform modular multi-connection of outdoor unit capability distribution is provided; Thereby improve the Energy Efficiency Ratio of sub-load, improve main frame, subsidiary engine compressor service life and system reliability.
The utility model another technical problem to be solved provides a kind of control system that makes the uniform modular multi-connection of outdoor unit capability distribution.
The technical scheme of the utility model is: a kind of large LED outdoor advertising case air-conditioner; Comprise the LED advertisement cabinet, by the refrigeration system that compressor, condenser, throttle part, evaporimeter constitute, the ventilation heat exchange system that on evaporimeter and condenser, is provided with; And electric controller; Said ventilation heat exchange system comprises condenser fan motor and evaporating fan motor, also comprises first temperature sensor and second temperature sensor that detects the outdoor environment temperature that are used to detect advertisement the temperature inside the box, and said controller also comprises first drive pattern and second drive pattern; When environment temperature is higher than TA; Controller is carried out first drive pattern, and when environment temperature was less than or equal to TA, controller was carried out second drive pattern.
Preferably, said evaporator chamber is installed on the open air, and ajutage connects evaporator chamber and LED advertisement cabinet, and said evaporator chamber is from outdoor return air.
Preferably, said first temperature sensor is located in the advertisement cabinet.
Preferably, when controller was carried out first drive pattern, compressor and evaporating fan motor were synchronous operation, and when controller was carried out second drive pattern, said compressor was out of service.
Preferably, be parallel with unloader in both sides capillaceous.
Compare with existing solution, the utlity model has following characteristics:
One, the utility model is the special-purpose air-conditioner of outdoor LED advertisement cabinet cooling, and the adjustment of air-conditioning design temperature makes it can be set in 35 ℃-40 ℃, has satisfied outdoor LED advertisement cabinet cooling requirement, and system's operation is energy-efficient.
Two, system can satisfy after the cooling needs according to outdoor temperature and the indoor temperature control compressor and the suitable start and stop of inner blower of reality, reduces greatly after the system energy consumption, has improved the life-span of compressor.
Three, when high temperature freezes,, play higher energy-saving effect during the high temperature refrigeration because throttle part adopts high pressure unloading valve and capillary paralleling binodal stream.

Fig. 2 is the refrigerant system configurations figure of the utility model LED outdoor advertising case air-conditioner;
Fig. 3 is the structural representation that is applied in the unloader of the utility model.
The specific embodiment
As shown in Figure 1, the large-scale outdoor LED display screen special air conditioner device of the utility model comprises compressor, evaporator chamber, ajutage 3, LED advertisement cabinet 4, first temperature sensor 7, second temperature sensor 9, exhaust duct 8, electric-controlled box 6, throttle part 5.Referring to Fig. 2-3; The refrigeration system of air-conditioner is linked in sequence and is formed by compressor 11, condenser 12, throttle part 5, evaporimeter 16; Wherein, compressor 11 and the setting on the machine 1 first outside of condenser 12, condenser fan motor 13, and evaporimeter 16, evaporator chamber, evaporating fan motor 17 are arranged on the second outer machine; Throttle part 5 comprises capillary 14 and unloader 15, and both are provided with in parallel connection.
Evaporator chamber outside second in the machine 2, be installed in outdoor, through ajutage 3 to 4 coolings of LED advertisement cabinet; Be provided with the controller that first temperature sensor, 7, the first temperature sensors 7 connect in the electric-controlled box 6 in LED advertisement cabinet 4, to controller transmission temperature signal data, by the start and stop of controller control compressor and evaporating fan motor.Simultaneously, outside second, also be provided with the controller that second temperature sensor 9 connects in the electric-controlled box 6 on the machine 2, the data of environment temperature send controller equally to; When environment temperature is higher than TA, carry out first drive pattern, when environment temperature is lower than TA; Carry out second drive pattern; And, when environment temperature is higher than TB, open unloader.
The control method of the large-scale outdoor LED display screen special air conditioner device of the utility model is following:
