Abstract
The utility model provides a condenser internally provided with a regeneration sub-cooler. The condenser comprises a condenser cylinder, a cooling water inlet, a cooling water outlet, a refrigerating agent inlet and a refrigerating agent outlet, wherein the cooling water inlet and the cooling water outlet are arranged at one end of the condenser cylinder; the refrigerating agent inlet and the refrigerating agent outlet are respectively arranged on the condenser cylinder; a shell and tube type condenser is internally provided with the regeneration sub-cooler; a regeneration sub-cooler inlet and a regeneration sub-cooler outlet are formed on the two ends of the regeneration sub-cooler; and the regeneration sub-cooler inlet and the regeneration sub-cooler outlet stretch out of the shell and tube type condenser. According to the condenser disclosed by the utility model, the internally-installed regeneration sub-cooler integrates the regeneration sub-cooler to effectively prevent a phenomenon that a compressor compresses with liquid and the degree of supercooling of a refrigerating agent of a condenser outlet is not enough, so that a unit can be efficiently and stably operated. Meanwhile, a pipeline of the unit is simple, is convenient to produce and is small in occupied area; and the cost of the unit is reduced and the leakage rate of the unit is reduced.
Description
Technical field
The condenser of used built-in backheat subcooler in the utility model heat exchanger, particularly screw type cold unit.
Background technology
Refrigeration machine, particularly adopt the refrigeration machine of dry evaporator in the process of operation, liquid refrigerant is through becoming the gas-liquid two-phase mixed state behind the throttle mechanism, owing to forming the gas-liquid layering, the gravity reason causes maldistribution after entering evaporimeter, variation along with operating condition, the phenomenon that the gaseous refrigerant that comes out to enter compressor from evaporator outlet is carried liquid refrigerant secretly is inevitable, thereby cause compressor Wet Compression even liquid hammer, reduced unit eer, long-play even can damage compressor.
Refrigeration machine is in the process of operation, variation along with operating condition, the phenomenon of degree of supercooling deficiency can appear in the liquid refrigerant that comes out from the condenser bottom, throttling action owing to pipeline when entering expansion valve produces flash gas, cause on the one hand and the expansion valve misoperation reduced unit eer on the other hand.
At present, a kind of way of routine is between the compressor inlet gas-liquid separator to be set at evaporator outlet, can prevent effectively that liquid refrigerant from entering compressor.Heat exchanger means of this extra increase makes the unit cost rise on the one hand; On the other hand, make unit pipeline complexity, strengthen the unit floor space, make troubles to production, increase the risk of system leak simultaneously.Another way is in condenser inside subcooler to be set, but also remains in some problems.
The utility model content
The purpose of this utility model is to provide a kind of solution above-mentioned pipeline complexity, strengthens the unit floor space, makes troubles to production, increases the condenser of built-in backheat subcooler of the problems such as risk of system leak simultaneously.
For solving the problems of the technologies described above, the condenser of the built-in backheat subcooler of the utility model comprises: condenser cylindrical shell and the cooling water inlet and the coolant outlet that are arranged on described condenser cylindrical shell one end; Refrigerant inlet and refrigerant outlet, described refrigerant inlet and described refrigerant outlet are separately positioned on the described condenser cylindrical shell; Also be provided with the backheat subcooler in described shell and tube condenser, be provided with the outlet of the import of backheat subcooler and backheat subcooler at the two ends of described backheat subcooler, the import of described backheat subcooler and the outlet of described backheat subcooler are stretched out outside the described shell and tube condenser.
Preferably, also be provided with refrigerant line in described condenser cylindrical shell, described refrigerant line one end is communicated with the cavity of described condenser cylindrical shell, and an other end of described refrigerant line is communicated with described refrigerant outlet.
The integrated backheat subcooler of the built-in backheat subcooler of the utility model can effectively prevent the phenomenon of the contracting of compressor band hydraulic pressure and condensator outlet cold-producing medium degree of supercooling deficiency in one, makes the operation of unit efficient stable.Make the unit pipeline simple simultaneously, convenient production, floor space is little, has reduced the unit cost, has reduced the unit slip.
