Embodiment
[0022] like Figure 1 to Figure 3 As shown, a double centrifugal separation flash evaporator includes a cylinder body 1 and a heat exchange tube 5. The lower part of the cylinder body 1 and the bottom end surface 130 enclose a refrigerant storage area, and the upper part is inserted into the heat exchange tube 5. The heat exchange tube 5 The pipe 5 includes a straight section 520 of the light pipe and a threaded section 510 sleeved on the outer side of the lower end of the straight section 520 of the light pipe. A gathering part 110 is provided at the top of the cylinder body 1, and the first refrigerant inlet pipe 2 is drawn out from the gap between the straight section 520 of the bare pipe and the upper part of the cylinder body 1, and the gas phase outlet is drawn out from the part where the straight section 520 of the light pipe exposes the cylinder body 1 The pipe 4 is provided with a second refrigerant outlet pipe 3 at the center of the bottom end surface 130 of the cyli...

The invention provides a double-centrifugation separation flash evaporator which comprises a barrel and a heat exchange pipe. A coolant storage zone is enclosed by the lower portion and a bottom surface of the barrel, the heat exchange pipe is inserted into the upper portion of the barrel and comprises a straight section of a polished pipe and a threaded section, the threaded section sleeves the outer side of the lower end of the straight section of the polished pipe, the straight section of the polished pipe is exposed out of the top of the barrel, a close-up portion is arranged on the outer side wall of the straight section of the polished pipe and the top of the barrel, a first coolant inlet pipe is led out of a gap between the straight section of the polished pipe and the upper portion of the barrel, a gas-phase outlet pipe is led out of the position, which is exposed out of the barrel, of the straight section of the polished pipe, a second coolant outlet pipe is arranged in the center of the bottom surface of the barrel, an inlet end of the second coolant outlet pipe faces downwardly, a pipe body of the second coolant outlet pipe is bent, then is turned over and upwardly extends, and an outlet end of the second coolant outlet pipe, a pipe orifice of the first coolant inlet pipe and a pipe orifice of the gas-phase outlet pipe face upwardly. The double-centrifugation separation flash evaporator has the advantages that gas can be thoroughly separated from liquid, refrigerants which flow into compressors are assuredly free of liquid, and accordingly efficient, energy-saving, reliable and stable running of integral systems can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of an air-injection enthalpy-increasing air conditioner or system, in particular to a double centrifugal separation flash evaporator. Background technique [0002] Air-injection enthalpy-increasing high-efficiency energy-saving air conditioners or systems need to use flash evaporators for complete gas-liquid separation to ensure that the refrigerant entering the air-injection enthalpy-increasing port of the compressor does not contain liquid. Therefore, the flash evaporator is an important part of the high-efficiency and energy-saving air-conditioning system with air injection, and its design quality has an important impact on the efficiency and reliable operation of the entire system. However, the existing flash evaporator still has the problem of incomplete gas-liquid separation. Contents of the invention [0003] The object of the present invention is to propose a double centrifugal separation flasher,...
