The heating and cooling load calculation is the first step of the iterative HVAC design procedure; a full HVAC design involves more than the just the load estimate calculation. Right-sizing the HVAC system, selecting HVAC equipment and designing the air distribution system to meet the accurate predicted heating and cooling loads, begins with an accurate understanding of the heating and cooling

  • • Static pressure (head) at pump location at no flow condition • Details of the fluid to be pumped including density, viscosity, etc • Whether the system is open or closed-circuit
  • on the pump curve showing that the actual cooling system flow for this pump will be approximately 975 gpm, about 2.5 Figure 1 Typical end-suction pump for 1,000 gpm and 78 feet of head
  • cap tube as a refrigerant control, because when the head pressures were low the evaporator would be starved and when the head pressures were high the flow rate could exceed the compressor capacity.
