A system for improving the performance of a heating, air conditioning, and ventilation (HVAC) system comprises rechargeable energy storage system (RESS) modules with high thermal mass, one or more auxiliary modules with low thermal mass, and a cooling system with a main refrigerant circuit and a refrigerant conditioning device. The HVAC system and individual parallel RESS refrigerant branches, connected in parallel to the auxiliary refrigerant branch(es), are connected to the main refrigerant circuit. An electronic controller determines the temperatures of the RESS module(s) and the auxiliary module(s) within their respective temperature ranges, conditions the refrigerant in the main circuit, and limits the refrigerant flow from it into the RESS refrigerant branch(es) when the temperature of the RESS module(s) is within a predefined temperature range.The control system also regulates the coolant flow from the main circuit to the auxiliary branch when the temperature of the auxiliary module is outside a second temperature range, in order to provide the target temperature coolant from the main coolant circuit to the HVAC system.

This invention discloses a multi-node thin-film thermocouple temperature measurement structure for total temperature in flow channels, belonging to the field of temperature measurement technology. It includes a metal shell and a multi-node temperature-sensing thin-film thermocouple. The metal shell has an elongated airflow hole on its windward side and a fixing groove inside. The thin-film thermocouple includes a substrate, positive and negative sensitive films, dual hot nodes, and a cold junction. The hot nodes are formed by overlapping the positive and negative films and are arranged on the windward end face. The cold junction is separated and leads out as wires. This invention achieves total temperature measurement by combining the shell and the thin-film thermocouple to form a stabilization structure. The dual nodes improve spatial resolution. The thin film has a small thermal mass and a response down to the microsecond level, capable of capturing transient pulsations. The substrate and film have matched thermal expansion, resulting in strong high-temperature stability. The structure is compact, with minimal flow field interference and good vibration resistance and sealing. It is suitable for accurate testing of the total temperature of high-temperature, high-speed airflow in engine flow channels, solving the problems of incomplete, inaccurate, and slow measurement in traditional temperature measurement methods.

This invention relates to the field of thermal power generation technology, and in particular to a heat and mass recovery system and method for a unit during FCB (Fuel Burner) operation. The system includes a control module 100, a communication module 200, and a distribution and regulation module 300 connected to the turbine unit. The control module 100 releases the working fluid during FCB operation and transmits it to the distribution and regulation module 300 for recovery via the communication module 200. The beneficial effects of this invention are that by recovering the heat and mass during FCB operation, the loss of the unit's working fluid is reduced, and the recovered steam is rationally recycled and utilized, improving the unit's economic efficiency and reducing the risk of short-term water loss.
