摘要： A building heating or cooling system is disclosed that includes an air handling system comprising an air delivery flow path (44) in fluid communication with a conditioned space (40) in the building. The building heating or cooling system also includes an electrocaloric heating or cooling system (10, 11) that includes first and second modules (12, 14). A first inlet receives air from the conditioned space (40) or the air delivery flow path (44) and directs it through the first or second module (12, 14) to a first outlet to the conditioned space (40) or the air delivery flow path (44), and a second inlet that receives air from conditioned space (40) or the air delivery flow path (44) and directs it through the first or second module (12,14) to a second outlet to outside the conditioned space (40).

摘要： The invention relates to a method, a system and a storage for detecting a fault of a HVAC system. The method comprises the steps of: obtaining room air temperatures and compressor equivalent runtime during the operation of the HVAC system; calculating a rate of change per unit time of the room air temperatures within the compressor equivalent runtime; and determining whether a fault occurs in the HVAC system based on a change in the rate of change per unit time of the room air temperatures. The invention can be applied to a HVAC system for an on-line fault detection, which is able to effectively detect a series of faculties and may output information such as an alert to help to increase the security and the user satisfaction of the HVAC system.

摘要： The present disclosure concerns a device and a method for chiller station management for providing chilled water to a load (30), a computer storage medium and a chiller station. The method for chiller station management includes: determining whether a chiller (10) with a low load exists in a chiller station and determining whether to allow to shut down one chiller (10) in the chiller station, when a certain chiller (10) in the chiller station transmits a surge risk signal; if yes, shutting down one chiller (10) in the chiller station to increase loads of other chillers (10); and if no, raising a chiller (10) outlet water temperature in the chiller station and/or lowering a cooling tower (20) outlet water temperature in the chiller station. The device and method for chiller station management according to the present disclosure provide a surge protection at a chiller station level, thereby effectively avoiding occurrence of surge in the chiller, and improving the efficiency and operation stability of the chiller station.

摘要： Embodiments include techniques for generating coordination maps for energy efficient chilled water and condenser water temperature resets in a chiller plant system. The embodiments include a controller configured to control and set thresholds for one or more parameters of the chiller system, wherein the chiller system includes one or more cooling tower, one or more pumps, and one or more water chillers, and one or more sensors operably coupled to the controller, wherein the one or more sensors are configured to measure values for one or more parameters. The embodiments also include a processor coupled to the controller, wherein the processor is configured to generate a coordination map based on the measured values and the thresholds for the one or more parameters, configure an operating setpoint for the chiller system based on the coordination map, and control the chiller system based at least in part on the configured operating setpoint.

摘要： A method and apparatus for controlling an HVAC system. The method may include receiving a fan speed signal from a fan control loop, and choosing among an independent mode, a first linked mode, and a second linked mode, depending on the fan speed signal. The method may also include providing a signal to a pressure control loop to reduce a speed of a supply air fan of an AHU, when the first linked mode is chosen. The method may further include providing a signal to a temperature control loop to decrease a speed of a heat exchange wheel, to decrease a flow rate of a heat exchange fluid to an evaporator coil, or both, when the second linked mode is chosen. The method may additionally include allowing the fan control loop to operate independently of the temperature and pressure control loops, when the independent mode is chosen.
