Abstract: The present disclosure provides a method and device for position determination, an air conditioning system, and a readable storage medium. The method for position determination includes: acquiring return air temperature information of each indoor unit; determining a first correlation coefficient between every two indoor units based on the return air temperature information; classifying indoor units based on the first correlation coefficient to obtain a number of classified groups; and generating relative position information in each classified group based on the first correlation coefficient by taking any one of the indoor units as a locating point. Maintenance personnel are not required to manually maintain a relative position relation of indoor units. Therefore, the maintenance difficulty of the relative position relation of indoor units is reduced, and a time cost and a labor cost required for maintenance are reduced accordingly.

Abstract: Disclosed herein are a system, method, and non-transitory computer readable medium for operating an energy plant. In one aspect, a system determines a ratio of flow rates between devices of the energy plant connected in parallel with each other in a branch. The system generates a candidate set of operating parameters of the devices according to the ratio of flow rates. The system predicts thermodynamic states of the devices operating according to the candidate set of operating parameters. The system determines whether the predicted thermodynamic states satisfy constraints of the devices. The system determines whether the predicted thermodynamic states satisfy a target thermal energy load of the branch based on the ratio of the flow rates. The system operates the energy plant according to the candidate set of operating parameters, in response to determining that the predicted thermodynamic states satisfy the constraints and the target thermal energy load.

Abstract: The present disclosure is directed to a single compressor HVAC system with hot gas reheat. The system includes a single compressor, a pair of condensers, a reheat heat exchanger, an evaporator, and an expansion device. Within the system, the refrigerant exiting the compressor is separated into two portions. In the cooling mode, the first and second portions of the refrigerant are directed from the compressor through the two condensers in parallel. In the reheat mode, the first portion of the refrigerant is directed through the first condenser, while the second portion of the refrigerant is directed through the reheat heat exchanger. The system also may include a head pressure control device that is designed to maintain the compressor discharge pressure within a desired range by adjusting the condenser fan speed.

Abstract: An HVAC (Heating, ventilation and air-conditioning) system for a machine room enclosure monitors the cycle time between powered-on and powered off intervals of a temperature controlled environment in the enclosure. Activation of a cooling unit occurs based on a computed time for attaining a cooling satisfaction threshold and an idle time until cooling is again called for based on a cooling demand threshold. Activation is adjusted based on a duration of the cycle times to avoid an excessive duration or brevity that imposes a strain on the cooling unit. The cooling demand and satisfaction thresholds are adjusted up or down to moderate the activated and idle cycle time. Additional adjustments are made for aged equipment that may be less efficient and more susceptible to strain from excessive cycling, and for extreme ambient temperatures that impose a greater burden and which may require additional time for reducing enclosure temperature.
