Machine Room Construction Tips
Machine Room Construction Tips
Machine room
Machine rooms must be well ventilated with temp. & humidity control, as well as drain functions, sufficient maintenance space shall be well considered.
Attention should be paid to machine room built by customers:
- Please refer to dimension drawings for plinth dimensions.
- Load capacity: the machine room foundation load is recommended as 1.5 times of the operation weight.
- Make sure that the foundation is level without sinking or overload (for rooftop installation). The load of a chiller is evenly distributed on the contact surface between the frame base rolling steel and the plinth.
- Anchor bolts:
- Chiller can be placed on the foundation directly without bolts (if there is a strong earthquake source or special anti-vibration requirement, please specify in a purchase order).
- Anchor bolts must be pre-installed for pumpset foundation per dimension drawings.
Foundation
- Ventilation:
- Poor ventilation leads to high humidity in the machine room, which may erode the unit. So serious attention should be paid to ventilation in the machine room. Please ventilate the machine rooms two times per hour and make up the combustion air. The volume of combustion air for a DFA is estimated at 1.3m³ for every kW fuel.
- Drainage:
- Chiller foundation must be on a high level in the machine room.
- All discharge pipes and drain pipes must be visable above the drainage.
- Machine room in basement must be built above a water ditch, which is equipped with an auto level-controlled submerged pump.
- Temperature:
- Machine room temperature must be controlled within 5~43°C. Lower temperature may crack heat exhange tubes and water box when the chiller is shut off; higher temperature may damage electrical components. Thermometer and over temperature alarm must be installed in machine room.
- Humidity:
- Machine room humidity must be lower than 85%. Higher humidity may impair insulation of electrical components.
