Due to the calculation parameter data provided is unknown, according to the conventional injection workshop system equipment and technological process used for cold heat
Estimate.In the end, cold heat calculation to the construction drawing design shall prevail.Calculation of quantity of cold consider summer dehumidification.
5. Choose cooler
Cold pause in shenyang DongYu refrigeration industry production of piston water chiller, unit models for LSZ300, compressor wheel for the valley (COPELAND) products, the unit has full automatic control functions, can realize automatic regulating cooling capacity.The unit heat exchanger to optimize the design of the shell and tube type, high thermal efficiency.
6. Air conditioning system choice
Use full air air conditioning system centralized low wind speed a return air handling;
The principle of determining the new air volume specification for design of air conditioning was determined by the new air volume of rules.
Purification areas are mainly based on the principle of air volume balance to determine the new air volume, which can not only maintain indoor positive pressure, exhaust and compensation system.Air handling system for modular air conditioning units, unit choose shenyang DongYu air purification products co., LTD.Set position in the dissection room on the second floor, the function of the air conditioning unit for the new, return air mixed paragraphs, the early effect filter, cooling section, the fan section, flow, steam heating, humidification, in effect filter, the wind section.Unit entrance for belt filter single fixed shutter fresh air.Fresh air in the electric insulation fresh air valve, and the air conditioning unit on supply chain, puts forward prevention unit freezing.Modular air conditioning unit system to send and return air duct ceiling air conditioning unit return air set fire dampers, when the fire broke out, the indoor temperature > 70 ℃, the electrical signal action, fire valve fuse fusing, and its chain of fan closed, air conditioning system is no longer running.
Comfort zone air handling equipment choose shenyang DongYu air conditioning purification and condole type air conditioning unit, can not only save the unit covers an area of, and can reduce the engineering cost.The determination of fresh air volume mainly workspace needed for each new air volume.Unit structure is compact, the internal air filter, cooler and heater.Chain system with return air fire valve and fan.
7. Air distribution
Hundreds of sending last grade purification corridor airflow organization, air supply device for high efficiency filter air diffuser, air return for single-layer shutter inlet with damping, give next time for the rest of the purification room air distribution, air supply device for high efficiency filter air supply outlet, the return air clip wall place with damping of single-layer shutter inlet of back side return air clip wall, the ceiling of the wind pipe connect room return air.
other
1. P - 1 laundry, the clothes, cleaning, cleaning between exhaust;
P - 2 before the sterilization room, after the sterilization room between the exhaust;
P - 3 potting, the washing bottle drying bottle part between the exhaust.Drying bottle exhaust cabin by the equipment itself.
When unclean in order to ensure the outdoor air in the system shutdown into indoor, so each exhaust system are set up at the exit exhaust filter box.
2. Because of this system unique structures, duct to the design and equipment selection to consider the project particularity.
3. High efficiency filter and back to the way the wind pipe assembly, ChengChongDian for color plate hanger, specific solutions can be found in the construction drawings.
Eight. Material selection
The wind pipe is made of galvanized steel plate, insulation glass wool board, thickness of 30 mm, choose aluminum foil glass fiber cloth layer, and glass wool board.Seamless steel pipe, steam pipeline in welding.Steam pipe insulation using aluminum foil glass cotton tube, thickness of 50 mm.Party a will pipe unit connected to computer room, cold water pipe welded steel pipe, insulation using aluminum foil glass cotton tube, thickness of 30 mm.
9. Specifications
1. The construction procedure and construction
1. 1 ventilation engineering before construction, construction personnel should check the ventilation engineering equipment and basic size, civil engineering to keep up with holes and location and size, and closely cooperate with construction.
Best at the end of the suspended ceiling construction before 1.2 duct construction, such as overlapping, prevent damage ceiling and duct insulation should be paid attention to.
1.3 high efficiency filter installation may not be out of the box, the installation must be installed in the clean room each major project all come to an end, clean room cleaning wipe, and comprehensive cleaning after 12 hours to purge air duct system, staff according to the personnel enter indoor cleaning requirements.
2. Duct elevation relative to the ground floor, the labeling shall prevail, the unit is meters.
