Abstract:
Disclosed is a refrigeration system, comprising refrigeration system components, a connecting pipeline, a switch structure, and discharging channels (123, 124; 623, 624). The refrigeration system components comprise three heat exchangers (101; 102; 112). The refrigeration system components can be connected via the connecting pipeline, and are combined into different working systems via the switch structure. When two heat exchangers are selected by the switch structure to form one working system and the saturation temperature corresponding to the internal pressure of the unselected heat exchanger is higher than the medium or environment temperature of the heat exchanger, a liquid refrigerant accumulates inside the non-working heat exchanger. According to the refrigeration system, the switch structure is arranged at either end of the non-working heat exchanger, so that the non-working heat exchanger is isolated from a working system cycle, and under the condition where the pressure at a low-pressure side (C; Q) of the working system is less than the internal pressure of the non-working heat exchanger, additional discharging channels (123, 124; 623, 624) communicate with the non-working heat exchanger and the low-pressure side (C; Q) of the working system, so that the refrigerant accumulating in the non-working heat exchanger is transferred to the system cycle, avoiding a lack of refrigerant in the system cycle.

Application number: 17/542,184

Abstract:
A control system includes building equipment configured to consume electrical energy and generate thermal energy, electrical energy storage configured to store and discharge electrical energy, and a controller. The controller is configured to determine, for a plurality of time steps within a time horizon, an amount of electrical energy to store in the electrical energy storage or discharge from the electrical energy storage using a value function. The value function includes an expected revenue from participating in an incentive-based demand response (IBDR) program, an expected cost of participating in the IBDR program, and a penalty cost based on an amount by which a predicted output of the building equipment or the electrical energy storage changes between time steps within the time horizon. The controller is configured to control the electrical energy storage to store or discharge the amount of electrical energy determined using the value function.

Application number: 17/510,774

Abstract:
A building management system includes one or more memory devices configured to store instructions thereon, that, when executed by one or more processors, cause the one or more processors to receive a publication by an agent on an agent communication channel, the publication comprising timeseries data, identify, based on the publication, an object entity of an entity database associated with the agent, wherein the entity database includes one or more object entities and relationships between the one or more object entities and one or more data entities, identify a data entity related to the object entity based on a relationship of the relationships relating the object entity and the data entity, and ingest the timeseries data into the data entity.
