Air Conditioning, Refrigeration Plant Room Design

Air Conditioning, Refrigeration Plant Room Design

1. Floor plan   

1) The plan of ventilation, air-conditioning and refrigeration plant room should be scaled up as necessary to make the design content clear, and the outline position and equipment number of ventilation, air-conditioning and refrigeration equipments such as chiller, fresh air unit, air-conditioner, circulating water pump, cooling water pump, ventilator, muffler, water tank, cooling tower, etc., should be shown, and the dimensions of the equipments and foundations from the walls or axes should be indicated, and the positions and directions of air ducts and water pipes connecting with the equipments should be shown. Draw the location and direction of air ducts and water pipes connected to the equipment, indicating the size, diameter and elevation. Mark the location of all equipment and various instruments, valves, flexible short pipes, filters and other piping accessories in the machine room.

2) Ventilation, air conditioning, refrigeration plant room section used to express the relative relationship of complex pipelines and vertical position relationship, drawing should be marked out the plant room plan of equipment, equipment foundations, pipelines and accessories of the vertical position, vertical size and elevation. The drawing should also be marked with the location of the pipeline connected to the equipment, size, equipment and accessory number and index number of the detailed drawing.

2. System flow chart   

Complex system piping connection relationship should be drawn system flow charts, for heat, refrigeration, air conditioning hot and cold water systems and complex wind systems should also draw system flow charts, and in the flow charts should be drawn out of the equipment, valves, control instrumentation, fittings before and after the relationship between the labelled medium flow direction, pipe diameter and equipment number and so on. The flow chart may not be drawn to scale, but the pipeline branches should be consistent with the plan.

3. Control schematic   

Control schematic diagram shows the control requirements of the system and the necessary control parameters, when the air conditioning, refrigeration system with monitoring and control, there should be a control schematic diagram, the diagram to illustrate the location of the equipment, sensors and control components to illustrate the control requirements of the system and the necessary control parameters.
