By means of a new modular process design, the system realizes the independent operation and free combination of refrigeration circulation in multi-stages, so as to achieve the purpose of adjustable working conditions, flexible output and high efficiency of energy utilization. The multi-stage energy storage of liquid CO2 can realize the flexibility of system power consumption, and acts as a standing safety module for firefighting to be put into the safe operation of the energy system.

The present invention discloses a gas-powder separation three-phase jet flow fire monitor system, including a gas-powder separation three-phase fire monitor head, a filter, a nitrogen pressurization apparatus and a dry powder tank. The dry powder tank is connected to a powder feeding pipe of the gas-powder separation three-phase fire monitor head through a pipeline. A nitrogen outlet pipe of the gas-powder separation three-phase fire monitor head is connected with one end of the nitrogen pressurization apparatus through the filter. The other end of the nitrogen pressurization apparatus is connected with the dry powder tank. The present invention is simple in structure and convenient to use. A cyclone separation apparatus of a dry powder pipeline of the fire monitor may separate nitrogen from conveyed ultrafine dry powder to enable the ultrafine dry powder to be fully mixed with a water-based fire extinguishing agent, thereby reducing an atomization degree of jet flow and enlarging a range of the fire monitor. In addition, the separated nitrogen enters the dry powder tank for recycling after being pressurized by the pressurization apparatus, thereby reducing the fire extinguishing cost.

An integrated detection and suppression system includes a fiber harness having at least one fiber optic cable for transmitting light defining at least one node arranged to measure one or more conditions. A light source is operably connected to the fiber harness to transmit light along the fiber harness to the at least one node. A control system is operably coupled to the fiber harness such that scattered light associated with the node is transmitted to the control system, wherein the control system analyzes the scattered light to determine at least one of a presence and magnitude of the one or more conditions. At least one suppressant outlet is associated with at least one node and is operably connected to the control system configured to initiate a response for the delivery of a volume of suppressant through a suppressant outlet associated with a particular node.

A fire extinguishing nozzle for a fire extinguishing system of a wheeled land vehicles includes a mounting portion, an extinguishing agent connection, a fixed nozzle section, and moveable nozzle sections. The mounting portion mounts the fire extinguishing nozzle to an outside portion of the wheeled land vehicle. The extinguishing agent connection couples the first extinguishing nozzle to an extinguishing agent reservoir. The fixed nozzle section is fixedly mounted to the mounting portion. The moveable nozzle sections form a telescopic nozzle arrangement configured to extend from the fixed nozzle section in a telescoping manner upon receiving a pressurized extinguishing agent at the extinguishing agent connection.

A protection device includes a casing assembly, a sealing film, and a temperature-sensitive actuating piece. A receiving chamber for receiving an inert gas is defined in the casing assembly. One end of the receiving chamber is provided with an opening. The sealing film is disposed at the opening to seal the receiving chamber. The actuating piece is disposed in the receiving chamber, and the actuating piece is provided with a piercing protrusion. When the actuating piece is deformed, the piercing protrusion pierces the sealing film.
