Abstract: Systems and methods for autotuning a HVAC system controller. The method may include receiving a performance coefficient and providing a step-input using an autotuner relay to measure ultimate gain and ultimate period in a controlled HVAC system. The method may also include adjusting the ultimate gain and ultimate period to account for a relay hysteresis, and applying a tuning rule to derive a proportional gain and an integral time for a controller of the HVAC system control loop. The method may further include updating the controller with the proportional gain and integral time, and verifying the proportional gain and integral time. Verifying the proportional gain and integral time may include setting a performance envelope having a tightness related to the performance coefficient, applying a step-input to provoke a closed-loop response, and comparing the closed loop response with the performance envelope to determine whether the closed-loop response is within the envelope.

Abstract: A method of operating a heat transfer system includes starting operation of a first heat transfer fluid vapor/compression circulation loop including a fluid pumping mechanism, a heat exchanger for rejecting thermal energy from a first heat transfer fluid, and a heat absorption side of an internal heat exchanger. A first conduit in a closed fluid circulation loop circulates the first heat transfer fluid therethrough. Operation of a second two-phase heat transfer fluid circulation loop is started after starting operation of the first heat transfer fluid circulation loop. The second heat transfer fluid circulation loop transfers heat to the first heat transfer fluid circulation loop through the internal heat exchanger and includes a heat rejection side of the internal heat exchanger, a liquid pump, and a heat exchanger evaporator. A second conduit in a closed fluid circulation loop circulates a second heat transfer fluid therethrough.
