Gas-liquid separator and refrigerating or heating pump device with same

Abstract

The invention discloses a gas-liquid separator and a refrigerating or heating pump device with the gas-liquid separator. The gas-liquid separator comprises a cylinder body, a refrigerant inlet pipe, a gaseous refrigerant outlet pipe, a liquid refrigerant outlet pipe and a flow regulating device. The flow regulating device is used for regulating the refrigerant flow of the gaseous refrigerant outlet pipe or the liquid refrigerant outlet pipe. By the adoption of the gas-liquid separator, a gaseous refrigerant in front of an evaporator or in the evaporator in a refrigerating or heating pump system can be extracted through the gas-liquid separator so that the liquid refrigerant can continue to enter the next cycle, and the heat exchange effect of the evaporator is improved; and when the gaseous refrigerant is used in front of the evaporator, the full-liquid refrigerant enters the evaporator so that liquid distribution of the evaporator can be uniform. By the adoption of the gas-liquid separator, the liquid refrigerant in a condenser can be extracted, the gaseous refrigerant is allowed to continue to enter the next cycle, and the heat exchange effect of the condenser is improved

Description

Technical field [0001] The present invention relates to the field of refrigeration or heat pumps, in particular to a gas-liquid separator and a refrigeration or heat pump device with the gas-liquid separator. Background technique [0002] Commonly used refrigeration or heat pump systems include compressors, condensers, throttling devices and evaporators, and most of them use dry evaporators. In this way, the throttled refrigerant is a gas-liquid two-phase. When it enters the evaporator, because the evaporator has multiple paths, the liquid is often unevenly separated, which affects the heat exchange effect of the evaporator. [0003] In addition, as the refrigerant flows along the evaporator pipeline, the refrigerant absorbs heat and evaporates. There are more and more gaseous refrigerants, less and less liquid refrigerants, and more and more contact surfaces between the gaseous refrigerants and the pipes. The thermal effect is getting worse and worse. Therefore, the flooded evap...

AI Technical Summary

Problems solved by technology

In this way, the throttled refrigerant is a gas-liquid two-phase. When entering the evaporator, due to the multiple channels of the evaporator, the liquid separation is often uneven, which affects the heat exchange effect of the evaporator.

[0003] In addition, as the refrigerant flows along the evaporator pipeline, the refrigerant absorbs heat and evaporates, the gaseous refrigerant becomes more and more, the liquid refrigerant becomes less and less, and the contact surface between the gaseous refrigerant and the pipe becomes more and more. The thermal effect is getting worse

Therefore, the flooded evaporator has a good heat exchange effect, but it is difficult to achieve in a dry evaporator

[0004] In the same way, for the condenser, as the refrigerant flows along the pipe of the condenser, the refrigerant dissipates heat and condenses, the liquid refrigerant becomes more and more, the gaseous refrigerant becomes less and less, and the contact surface between the liquid refrigerant and the pipe becomes smaller and smaller. The more, the worse the heat transfer effect
