Abstract
A device and method for continuously detecting refrigerant in water, wherein the water which possibly containing refrigerant gas is fed into a vessel via a water inlet, and air is supplied to the vessel via a gas buffer, and the water is pumped out of the vessel via a pump, wherein a lower pressure is set in the vessel than in the supplied water, so that the possibly containing refrigerant gas separates from the water. Gas released from the water is fed from the vessel to a refrigerant detector, where the concentration of the refrigerant gas is measured and the gas flow exiting from the refrigerant detector is returned via a gas return line to the vessel.
Claims19
A device for continuously detecting refrigerant in water, comprising:
- a vessel having a main inlet for supplying water to the vessel,
- a gas buffer to supply air to the vessel,
- a main outlet for discharging water from the vessel,
- a pump connected to the main outlet for adjusting a pressure in the vessel,
- wherein a lower pressure is set in the vessel than in the supplied water so that refrigerant gas is separated from the water,
- a refrigerant detector for measuring a concentration of refrigerant gas is connected to a refrigerant gas side of the vessel, wherein the main inlet is provided on the refrigerant side of the vessel, wherein the refrigerant gas separated from the water is fed from the vessel to the refrigerant detector, and wherein gas including the separated refrigerant gas is returned to the vessel in a gas return line via the gas buffer through the main inlet;
- wherein a ski board is located inside the vessel on which the water forms a stream so that gas bubbles in the water can reach a surface.
A method for continuously detecting refrigerant in water, comprising:
- feeding water containing refrigerant gas into a vessel via a main inlet provided on a refrigerant side of the vessel,
- supplying air to the vessel via a gas buffer,
- pumping the water out of the vessel via a pump,
- setting a lower pressure in the vessel than in the supplied water, so that refrigerant gas is separated from the water,
- feeding the gas released from the water from the vessel to a refrigerant detector connected to the refrigerant side of the vessel,
- measuring a concentration of the refrigerant gas with the refrigerant detector, and
- returning the refrigerant gas separated from the water to the vessel in a gas return line via the gas buffer through the main inlet as stripper gas.
