What is the effect of using a gas-liquid separator for a carbon dioxide heat pump system?

The utility model relates to a gas-liquid separator for a carbon dioxide heat pump system. The utility model relates to a gas-liquid separator for a carbon dioxide heat pump system, comprising a cylinder body with an air inlet and an air outlet, one end of the oil return pipe is communicated with the air outlet, the other end of the oil return pipe is suspended and staggers from the axis of the air inlet pipe, and at least one oil return hole is arranged radially at the turning point of the oil return pipe. The utility model has the function of effectively realizing the gas-liquid separation of the carbon dioxide heat pump system, and the liquid, I. E. Lubricating oil and carbon dioxide liquid, is smoothly returned to the compressor at a constant flow rate in a mixed state, avoid “Liquid hit”or “Burn cylinder”accident and other beneficial effects.
