Problems solved by technology
To make CO 2 Refrigerant air conditioners achieve higher performance, CO 2 A regenerator is installed in the circulation system to exchange heat between the refrigerant at the outlet of the gas cooler and the refrigerant at the outlet of the evaporator, which can significantly increase the CO 2 The energy efficiency ratio of refrigerant air conditioners, the effect of regenerators on the energy efficiency ratio of conventional refrigerant systems is not obvious
Separately setting the regenerator and the gas-liquid separator will make the system redundant, increase the number of welds, and increase the risk of system use

The invention discloses an integrated heat regeneration gas-liquid separator and a refrigerating system for a carbon dioxide refrigerant air conditioner. The gas-liquid separator comprises a shell, wherein the shell is provided with a gas inlet pipe and a gas exhaust pipe, the gas inlet pipe is arranged at the lower portion of the shell, a heat regeneration pipe is further arranged in the shell, the gas exhaust pipe comprises an outer pipe section extending from the upper portion of the shell and an inner pipe section of a U-shaped structure, the port of the inner pipe section is located at the upper portion of an inner space of the shell, the heat regeneration pipe comprises a heat regeneration pipe gas inlet main pipe, a heat regeneration pipe gas outlet main pipe and two or more branchpipes connected between the heat regeneration pipe gas inlet main pipe and the heat regeneration pipe gas outlet main pipe in parallel, the heat regeneration pipe gas inlet main pipe extends out of the upper portion of the shell, and the heat regeneration pipe gas outlet main pipe extends out of the lower portion of the shell. The integrated heat regeneration gas-liquid separator for the carbon dioxide refrigerant air conditioner has the advantages that heat exchange is efficient, assembly is simple, the cost is low, and a protective effect on a compressor of the refrigerating system is achieved.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an integrated heat recovery gas-liquid separator and refrigeration system for carbon dioxide refrigerant air conditioning. Background technique [0002] Currently, CO 2 Refrigerants are valued by people for their environmental protection performance with an ozone depletion potential of 0 and a global warming potential of 1. To make CO 2 Refrigerant air conditioners achieve higher performance, CO 2 A regenerator is installed in the circulation system to exchange heat between the refrigerant at the outlet of the gas cooler and the refrigerant at the outlet of the evaporator, which can significantly increase the CO 2 The energy efficiency ratio of the refrigerant air conditioner, and the effect of the regenerator on the energy efficiency ratio of the conventional refrigerant system is not obvious. Separately setting the regenerator and the gas-liquid separator w...
