Abstract

The invention relates to a directional flow efficient condenser device and a using method thereof. The usually adopted condenser at present is large in volume and low in energy efficiency. The technical scheme of the invention is as follows: high pressure overheated gas-phase mixture of refrigerant and refrigerating oil is subject to directional flow distribution in a cylinder, so that the heat exchange process is more sufficient, and the directional flow efficient condenser device is composed of the cylinder, a gas inlet pipe, a vertical gas channel partitioning plate, a horizontal gas channel partitioning plate, a condenser pipe bundle, a supporting plate, a refrigerant liquid outlet, a pipe sheet and a refrigerating medium outlet. The invention has the beneficial effects that the gas channel partitioning plates are adopted to realize directional flow distribution, thus being a technology having simple structure, easy manufacturing and low processing cost; that the phase change process of the mixture of refrigerant and refrigerating oil is more perfect and the heat exchange process is more sufficient; and that the heat energy efficiency is enhanced by 8-12% in comparison with the existing condenser, and the entire condenser volume can be reduced, thus being economic and energy-saving.

Description

technical field [0001] The invention relates to a heat exchanger device, in particular to a condenser device and a use method of a refrigeration and air-conditioning system. Background technique [0002] The main components in the refrigeration and air conditioning system include: compressors, oil separators, condensers, liquid receivers, expansion valves, evaporators and other pipelines and electronic control equipment. The refrigeration cycle process is that the high-pressure superheated refrigerant and the refrigerated oil gas phase mixture discharged from the compressor pass through the oil separator for gas-liquid two-phase separation, and then the refrigerant enters the condenser and condenses into a high-pressure superheated refrigerant through the normal temperature refrigerant. The cold liquid, after throttling by the expansion valve, is vaporized in the evaporator through the normal temperature brine to form a low-pressure superheated vapor, which is sucked by the ...
