The invention discloses a flash evaporator and a refrigeration device with the flash evaporator. The flash evaporator comprises a shell, a liquid discharging pipe, an air discharging pipe and an inlet pipe, wherein the pipe diameter of the liquid discharging pipe is D1 (mm); the pipe diameter of the air discharging pipe is Dq (mm); the pipe diameter of the inlet pipe is D (mm); and the size of the flash evaporator at least meets the following relation: FORMULA where m1 is the coolant circulating flow of the liquid discharging pipe, Rho1 is the density of coolants in the liquid discharging pipe, v1 is a set speed value of the coolants in the liquid discharging pipe, m2 is the coolant circulating flow of the air discharging pipe, Rho2 is the density of coolants in the air discharging pipe, and v2 is a set speed value of the coolants in the air discharging pipe. According to the flash evaporator disclosed by the embodiment of the invention, the performance reduction caused by extremely high loss of the coolants due to extremely small pipe diameters can be avoided, and the phenomena of waste of materials and large occupation space due to extremely large pipe diameters can be also avoided.
Description
technical field [0001] The invention relates to the refrigeration field, in particular to a flash evaporator and a refrigeration device with the same. Background technique [0002] For a refrigeration system using a flash evaporator, the throttling gaseous refrigerant (this part of the gaseous refrigerant does not participate in heat exchange even if it passes through the heat exchanger, but occupies the space of the heat exchanger) can be separated without passing through the heat exchanger. Instead, it goes directly back to the compressor, which reduces pressure loss and improves heat exchanger efficiency. However, the structure of the flash evaporator in the prior art causes a large pressure loss of the refrigerant, which reduces the performance while occupying a large space and high cost. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the p...
