A safety system for a heat pump system includes a plurality of valve units each having refrigerant pipe portions with control valves, a refrigerant leakage detector, and a casing accommodating the valves and the refrigerant leakage detector and formed with first and second openings. The safety system further includes 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.

Safety system and method for constructing air conditioning system

A valve unit for a heat-pump system, includes: a liquid refrigerant pipe portion; a gas refrigerant pipe portion; a liquid control valve disposed in the liquid refrigerant pipe portion; a gas control valve disposed in the gas refrigerant pipe portion; a casing accommodating the liquid control valve and the gas control valve; and an air-discharge mechanism that discharges air in an internal space of the casing to an external space outside the casing in response to a refrigerant leakage in the casing.
