Integrated condensing flooded evaporator device and using method thereof

Abstract

The invention relates to an integrated condensing flooded evaporator device and a using method thereof. A single condenser and a single flooded evaporator are adopted in the prior art, and the technical scheme is that: the condenser and the flooded evaporator are combined in the same cylinder. The device consists of a cylinder, an air inlet pipe, a condensing pipe bundle, a condensing side supporting plate, a refrigerant liquid outlet, a condensing side pipe plate, a condensing side secondary refrigerant inlet / outlet, a double-layer clapboard, a liquid inlet pipe, a dispenser, an evaporating pipe bundle, an evaporating side supporting plate, an oil return low interface, an oil return high interface, an air suction distributor, an air outlet pipe, an evaporating side secondary refrigerant inlet / outlet and an evaporating side pipe plate. The invention has the advantages that: two heat exchanger devices, namely the single condenser and the single flooded evaporator, are integrated in the same cylinder; and the device is compact in structure, saves pipelines, valves and raw materials by 20 percent, reduces pressure drop by 10 percent, reduces leakage points, wholly improves the energy efficiency by 8 to 10 percent, and is economic and energy-saving.

Description

technical field [0001] The invention relates to a heat exchange container device in a refrigerating and air-conditioning system, in particular to an integrated condensing flooded evaporator device in the refrigerating and air-conditioning system and its use method. 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 th...

AI Technical Summary

Problems solved by technology

[0003] In the refrigeration and air-conditioning system, the current common technology is to use a separate condenser and flooded evaporator, the overall structure is loose, the manufacturing cost is high, it is not economical, and it is not energy-saving; there are many valves, more leakage points, and serious refrigerant leakage. , pollute the environment; the pipeline system is complex, the pressure drop increases, resulting in reduced energy efficiency; the effect of supercooling and superheating is not obvious
