摘要： A dynamic control valve assembly for use in filling a liquid carbon dioxide storage and gas delivery system is provided, the assembly comprising: a valve body; an end nut with an inlet port for receiving liquid carbon dioxide; a chamber; an inlet cavity; a liquid port; a gas port; and a dynamic compound valve stem assembly for blocking the gas port while liquid carbon dioxide is delivered through the inlet port and allowing the liquid carbon dioxide to flow through the liquid port for storage in a liquid cylinder, and open the gas port and block the inlet port in order to allow carbon dioxide gasses from boiling liquid carbon dioxide within the liquid cylinder to pass through the gas port for storage in a gas cylinder until system pressure and temperature equilibrium is reached. The dynamic compound valve stem assembly comprises: a stem body having an inlet port poppet and a gas port poppet; an inlet cavity collar; and in some embodiments a collar biasing spring. The compound valve assembly is adapted to block the inlet port upon completion of the delivery of liquid carbon to the system when the system has an initial low pressure. The carbon dioxide gas may then be drawn from the gas cylinder for use in use in carbonated beverages and other applications such as agricultural and medical uses.

摘要： A refrigeration cycle apparatus includes a gas leakage sensor and a control device. When refrigerant leakage is detected by the gas leakage sensor, the control device performs a first mode operation to operate a compressor in such a state that a four-way valve is set to a cooling operation state, an expansion valve is opened, and a first shutoff valve is closed. After performing the first mode operation, the control device performs a second mode operation to operate the compressor in such a state that the four-way valve is set to a heating operation state and the first shutoff valve is closed.
