Description

This invention relates to refrigeration engineering.

Known condensers of refrigerating machines containing a housing with a refrigerant vapor inlet line.

In the known condensers, the zones are characterized by different heat transfer conditions, and in the overheating zone the heat transfer coefficient is lower than in the condensation zone. The presence of the overheating zone, which takes place mainly in the condensers of cascade refrigerating machines, does not allow efficient use of the heat meter surface of the condenser.

The purpose of the invention is to increase the thermodynamic efficiency of a capacitor.

This is achieved by the fact that on the vapor inlet line there is an installation of a bubbling chamber connected to the liquid cavity of the casing, mainly in the zone of the greatest loss but the principle of a communicating vessel, with the refrigerant inlet line connected to the vapor space of the casing.

The drawing shows the described capacitor.

Heat exchanger tubes 2 are placed in the condenser case 1, inside of which, for example, the upper stage refrigerant boils or coolant circulates. In lnipi 3 refrigerant vapor inlets installed

a bubble chamber 4, which is connected by a pipe 5 to the fluid cavity of the housing 1 in the zone of the greatest supercooler. The line 3 for the introduction of refrigerant vapor by pipe 6 is connected to the vapor space of the housing 1 above the liquid level.

Refrigerant vapor via lippi 3 inlets enters the bubbling chamber 4, where they are bubbled through a layer of liquid condensate coming from housing I via pipeline 5. Section1 of the T1 pipeline 5 provides the specified flow rate of supercooled kopden.sat. In bubbling. 1cc, at least 4 the superheat of the nozzle coolant is reduced due to the heat transfer to the condensate. The resulting condensate banks are replaced with the post-coolant and fed into the body of the condenser. Pa external to; verX) Nostp heat exchangers 2 and the rest of the refrigerant condenses and drains into the lighter part of the orifice 1. Part of the refrigerant from line 3 of the inlet, mine the bubbling chamber 4, the pipeline 6 ayustunayt into the body 1 1 condensate. The cross section of pipe section 6 01 eliminates such a coolant flow rate at which efficient operation of the heat exchange pipe pipes 2 does not deteriorate. When the ondensarore is inoperative, a pressure b is equalized with the help of a pipe b, and the capacitor prevents the condensate from flowing through livery 3 into the refrigerating system through three liquefaction systems in it.
