HVAC System Design
Selection of Systems (Classification of Machines)
Based on the building survey report we will offer/think about the HVAC system which may deploy to the site, all are conceptual. You will have options to choose the right system. We will give a budgetary proposal and prepare detail design related documents.
Step - 3
HVAC System Design
Load Calculation (Cooling and Heating loads)
Performing heating and cooling load calculations for all conditioned building spaces to determine the zones and capacity of the new heating, ventilation, and air conditioning.
Factors of Calculations: conduction and convection heat transmission, air ventilation and infiltration, solar heat gain, maximum anticipated staff and public occupancy, existing and future equipment, machines, appliances, and other internal building heat sources.
Identify and locate all of the equipment, machines, appliances, and other similar internal building heat sources on the floor plans of the building. Include their BTU ratings so they can be used for the heating and cooling load calculations and future air conditioning system balancing.
Step - 7
HVAC System Design
Chill Water Pipe Designing
Piping which join the pump, the chilled and FCU or AHU in which chill water is supplied is called secondary or chill water piping.
Methods for chilled water pipe design - Constant velocity method and Veclocity + Friction method.
Step - 9
HVAC System Design
Selection of type and size of equipment
Selection of type and size of equipment is crucial as far as the smooth and cost-effective system. We will ensure it during the design of a system.
Step - 10
HVAC System Design
Planning the location of each piece of equipment in the building
Planning the location of each piece of equipment in the building is important in during design to get most out of the system. Our team will always emphasise on the matter to ensure efficiency.
Step - 11
HVAC System Design
Drafting and documentation of HVAC system
Duct layout/Plant layout - We will provide you the complete design layout with all used components like plenums, ductwork, blowers, registers, grills, diffusers, dampers, volume adjustment devices, controls, etc. Outside air ventilation and air change quantities for the building.
Preparation of Bill of Quantities (BOQ) - List of item in project and its quantity as per the final design drawings.
Preparation of material specification - Detail of a material / equipment by the design, construction and performance of all listed item in BOQ.
Preparation of tender document - Tender Drawings, Tender Bill of quantity and Tender specification (will contain scope of work, approved makes and material specification).
Step - 12
HVAC System Design
Approval of all data sheets and technical submittal
Verification of contractor construction document (like equipment technical data sheet, GA drawings, equipment performance curve) and construction drawings and approving the same.
Step - 13
HVAC System Design
Construction and Commissioning Management
Verification of project schedule, inspection of supplied equipment’s, inspection of work quality and final verification of equipment commissioning report and approving the same.
