Tube Shell Type Water Cooled Heat Exchanger

Evaporator for Screw Chiller

The refrigerant is completely evaporated in the tube and overheated to become a superheated gas, which

facilitates the automatic adjustment of the supply volume using the thermostatic expansion valve.

The refrigerants commonly used are R22, R134a, R407C, R410A and the like. Because the refrigerant

tube evaporation, as long as the tube flow rate of more than 4 m / s, you can put the tube of lubricants

back to the compressor, back to the oil convenient.

In the design, the shell side adopts the E-type structure (baffle type) specified by GB151 or TEMA. The

size of the baffle plate is 15% ~ 50% of the gap according to the physical properties of the refrigerant and

the flow rate. , The flow rate of the baffle notch is approximately equal to the flow rate of the refrigerant in

the transverse direction of the refrigerant. In order to ensure the heat transfer effect, the gap between the

baffle and the cylinder is smaller than or equal to GB151 or TEMA The minimum clearance, especially in

the case of low temperature, these gaps are particularly important, because in low temperature, the

refrigerant is generally high viscosity fluid, slow flow, thermal resistance is relatively increased, the gap

leakage is more obvious, so low temperature The case of the control of the gap must be more stringent.

The heat transfer tube adopts the internal strengthening and efficient heat transfer tube.

The inside of the heat transfer tube adopts the spiral groove type. Generally, there are 32 to 75 trenches,

which are mainly used to enhance the heat transfer effect inside the tube. But also do the corresponding

strengthening, the heat transfer tube according to the different refrigerant can be used copper T2, high

phosphor copper TP2, nickel copper BFe10-1-1, tin copper HSn70-1, aluminum and copper HA177-2 and

other materials.

The heat transfer tubes and tubesheets are generally connected by means of expansion joints. A set of

dispensers are normally provided at the inlet of the refrigerant for the equal distribution of the gas-liquid

mixture.

The dry evaporator is generally suitable for use in compressor refrigeration systems with displacement

less than 2000 m3 / h , It is preferable not to use this type of evaporator due to the uneven distribution of

the refrigerant in the large-scale system.
