摘要: Provided a safety system for a heat pump system, comprising a plurality of valve units each having refrigerant pipe portions with control valves, a refrigerant leakage detector, and a casing (400e) accommodating the valves and the refrigerant leakage detector and formed with first and second openings (420, 430). The safety system further comprises a connection structure connecting the internal spaces of the casings via the first and second openings, and a discharge structure connected to the connection structure or one of the casings and configured to discharge air from the internal space of the casing in which a refrigerant leakage has occurred. The casing has first and second lateral faces facing different directions, and the first opening is formed in the first lateral face and the second opening is formed in the second lateral face.

摘要: Provided an air conditioning system (100m) comprising a compressor unit (111m), a heat exchanger unit (101m) for exchanging heat between air and first refrigerant,, an indoor unit (120m) for exchanging heat between air and second refrigerant which is subjected to a heat exchange with the first refrigerant, and a valve unit (200m). The heat exchanger unit is installed in a first space (931h), and the compressor unit and the valve unit in a second space (932h). The system further comprises a first leakage detector (501m) disposed in the second space a, and a ventilation control structure (730, 800m, 440) for switching the state of the second space from a first state to a second state when the detected concentration is equal to or greater than a first detection value threshold, in the second state a ventilation of the second space being promoted more than in the first state.

摘要: Provided a safety system (700) comprising: a plurality of valve units (200) for a heat pump system, a connection structure (710), and a discharge structure (720, 730). Each valve unit has refrigerant pipe portions (311, 330) with control valves (364, 365), a casing (400) accommodating at least the valves, and a refrigerant leakage detector (500). The connection structure connects the internal spaces of the casings via openings (420, 430) of the casing. The discharge structure is connected to the connection structure or one of the casings and configured to discharge air from the internal space of the casing in which a refrigerant leakage has occurred. The discharge structure includes a shared duct (720) connected to the connection structure or one of the casings, and a ventilator (730) disposed to the shared duct.

摘要: Provided an air conditioning system (110h) comprising a compressor unit (111h) including a compressor (112h), a heat exchanger unit (101h) including an outdoor heat exchanger (102h), an indoor unit (120), and a valve unit (200h) including a liquid control valve (364) and a gas control valve (365). The heat exchanger unit is installed in a first space (931h), while the compressor unit and the valve unit are installed in a second space (932h). The system further comprises a first leakage detector disposed in the second space a, and a ventilation control structure that is configured to switch the state of the second space from a first state to a second state when the detected concentration of the first refrigerant is equal to or greater than a first detection value threshold, in the second state a ventilation of the second space being promoted more than in the first state.
