Unit air handling function section with air mixing, current sharing, filtration, cooling, primary and secondary heating, dehumidification, humidification, blower, return fan, water spray, muffler, heat recovery and other unit body.
Shandong Century Changlong New Energy Co., Ltd. modular air conditioner unit implementation of the implementation of national standards:
GB / T14294-2008 "modular air conditioning unit"
GB / T14296-2008 "Air cooler and air heater"
GB50736-2012 "Civil building heating and ventilation and air conditioning design specifications"
And by the State Equipment Quality Supervision and Inspection Center (China Academy of Building Air Conditioning) test, the indicators have reached the national standard requirements.
The main function of the fresh air filter section, preheat section, return section, hot pipe section, cold section, fan section and other functional segments for users to choose a combination, focusing on the following functional sections:
 1, cold coil (hot coil) section
⑴, cold coil (hot coil) section with cooling down, retaining function, can also be used in 65 ℃ below the hot water for air heating, the bottom with a water tray and condensate drain.
⑵, surface cooler (heat exchanger) using air-conditioning high-quality copper tube to wear aluminum technology, the overall mechanical up tube once completed, the combination of tight, high heat transfer efficiency; operation and maintenance, clean and convenient.
⑶, fin punching for the double flanging, to ensure uniform spacing between the film, considering the wind resistance, water resistance, fan motor power, heat transfer area and other factors, through computer-aided optimization design, so that the film spacing to achieve the optimal value, Different water heaters and the temperature difference between the inlet and outlet water to maintain a reasonable range, and fundamentally solve the problem of water and silt in the tube, the surface of the condensate condensate drain at the automatic anti-suction device, Can be discharged in the negative pressure condensate, to ensure safe and efficient use of the user. The use of the United States OAK high-speed press punching fins, red film process added OAK oil in the fin after the formation of natural evaporation, no traces of oil in the unit running the standard wind speed without water.
⑷, conventional airtight detection pressure of 2.0MPa, the maximum working pressure of 1.6MPa.
⑸, for the fixed end of the copper tube through the design of the second hole, allowing the heat exchanger copper tube in the unit work can be smooth displacement, so as to prevent the impact of soft drinks, thermal stress caused by excessive copper cracking phenomenon.
 2, fan section:
Unit selection of the fan for the mechanical parts sentinel air conditioning fan manufacturers to produce double into the wind forward low noise centrifugal fan. All the impeller of the fan are subjected to dynamic balance detection, impeller bearing the use of low noise ball bearings, without oil maintenance, long service life. Unit selection of the fan noise is low, good aerodynamic performance, the impeller and the scroll of the connection structure, making maintenance when the replacement of impeller bearings and the motor is very convenient. Unit in the lower part of the fan equipped with JG rubber shear shock absorber, making the whole fan running a small vibration, low noise.
Motor insulation class B or F, protection class IP54 or IP55; motor wiring cable with high-strength protection casing and joint protection, good moisture resistance.
 3, the filter section:
According to the needs of the user unit can be equipped with early effect, efficiency and high efficiency filter, for the general requirements of the unit are equipped with early effects filter.
The initial effect filter is generally plate structure, the filter frame is galvanized plate pressure type, both sides with pressure type galvanized steel net reinforcement, internal non-burning filter material. Filtration efficiency G3 (weight efficiency ≥ 60%), the initial resistance 75Pa, the final resistance of 150 Pa, filtration efficiency F5 (counting efficiency of 50%; according to the performance of different filter), the efficiency of the filter filter up to F9.
 4, dry steam humidification section:
Humidification principle: connected to the decompression and filtration of the saturated steam source, saturated steam in the double nozzle within the jacket of the horizontal flow, the flow into the elbow, the central nozzle preheating, the baffle, into the evaporation chamber; Due to the sudden increase in the end of the evaporation chamber, the steam flow rate is reduced, the condensed water contained in the saturated steam is separated and discharged through the condensate outlet at the bottom of the evaporation chamber; the steam separating the condensed water enters the drying chamber which has been preheated, The drying chamber is filled with stainless steel medium to absorb the noise of the flowing steam and filter and separate the moisture remaining in the steam. The opening of the regulating valve, the pressure in the drying chamber is reduced, the vaporization temperature is reduced, the moisture remaining in the steam is heated, Vaporized, to achieve the saturated steam soda separation; dry steam through the control valve into the central nozzle, from the stainless steel silencer mesh into the airflow inside the reverse flow into the air, to achieve the humidification of the air. Features:
① isothermal humidification, humidification efficiency, up to 95% or more.
② the introduction of foreign advanced steam - water separation technology, so that more thorough separation of soft drinks, no water spray phenomenon.
③ unique spray bar structure, to ensure that the sprayed dry steam without water and noise.
 5, the unit structure:
The frame of the air conditioner is assembled by an aluminum alloy frame beam. The frame beam is made of special rolling equipment. The cross section is □, and the inner and outer layers of the box are colored steel plate or galvanized sheet. It is resistant to corrosion, acid, alkali and salt for 15 years. Will not be due to moisture leaving the insulation performance, so the unit's insulation performance and air tightness lasting. The unit box is sealed and reliable.
