Control Device for HVAC Systems with Inlet and Outlet Flow Control Devices
First Claim
1. A process for controlling operation of a heating, ventilation and air conditioning system, comprising:
- providing a heating, ventilation and air conditioning system having an evaporator, a condenser, a compressor having an inlet and an outlet, and at least one flow control device in communication with the inlet or the outlet or both the inlet and the outlet;
measuring a performance parameter of the heating, ventilation and air conditioning system;
determining a performance parameter measurement indicative of onset of surge;
determining a surge line of the heating, ventilation and air conditioning system based upon the performance parameter measurement; and
independently controlling the at least one flow control device based upon the performance parameter to mitigate an onset of the surge.

Abstract
A process for controlling operation of a heating, ventilation and air conditioning system broadly comprises providing a heating, ventilation and air conditioning system having an evaporator, a condenser, a compressor having an inlet and an outlet, and at least one flow control device; measuring a performance parameter of the heating, ventilation and air conditioning system; determining a performance parameter measurement of the flow indicative of onset of surge; determining a surge line of the heating, ventilation and air conditioning system based upon the performance parameter measurement; and independently controlling the at least one flow control device based upon the performance parameter to mitigate an onset of the surge.
