First, HVAC engineering
1. Equipment: statistical calculation of air conditioning cooling load and total cooling load, including cooling water and NMP circulating water. Select an appropriate number of 750RT centrifugal units, and count dehumidifier units, heating cabinets and refrigeration cabinets (some are ceiling cabinets and some are power cabinets, depending on the actual situation) through the division of air conditioning areas. The air conditioning box and dehumidification equipment are mainly placed above the mezzanine of the auxiliary room;
2. Air duct: Dew point of dehumidification is -20℃~-30℃, in which the return air duct in -50℃ area adopts stainless steel all-welded air cabinet with a thickness of about 1.2mm, and the other air ducts adopt galvanized angle steel flange air ducts. B 1 grade plastic board and glass wool insulation board are selected for insulation, and the insulation thickness is greater than 32 mm..
3. Water pipes: seamless steel pipes (≥DN200) and galvanized steel pipes (< DN200) are used for air conditioning water pipes. The refrigeration pump is started by frequency conversion.
Second, the lighting engineering
1. Workshop lighting includes purification lamp, industrial and mining lamp and explosion-proof lamp, and maintenance lighting is industrial and mining lamp. Emergency lighting should be configured according to fire control requirements;
2. The lighting control part adopts the way of combining centralized and dispersed phase, and each workshop makes centralized lighting master box according to fire control requirements, and each workshop makes sub-lighting boxes, which is convenient for maintenance and control. The corridor area adopts double control tripping, and the lights are switched on and off at ordinary times to save energy;
3. The lighting circuit adopts flame-retardant soft core wire, and the conduit adopts galvanized conduit. The emergency lighting line is connected with the double-loop incoming line. Place and install lamps according to the field equipment in the workshop.
I suggest you consult a professional cleaning engineering company. After all, professionals know these things better. The famous cleaning engineering company near Wenzhou is CEIDI Xidi, you can ask. Many of my clients say that the projects this company has done are quite good. These Baidu can be found.
